‘Benign’ Adrenal Gland Tumors Might Cause Harm to Millions

Posted on January 8, 2022 by MaryO

Millions of people are at increased risk of type 2 diabetes and high blood pressure and don’t even know it, due to a hidden hormone problem in their bodies.

As many as 1 in 10 people have a non-cancerous tumor on one or both of their adrenal glands that could cause the gland to produce excess amounts of the stress hormone cortisol.

Up to now, doctors have thought that these tumors had little impact on your health.

But a new study out of Britain has found that up to half of people with these adrenal tumors are secreting enough excess cortisol to raise their risk of diabetes and high blood pressure.

Nearly 1.3 million adults in the United Kingdom alone could suffer from this disorder, which is called Mild Autonomous Cortisol Secretion (MACS), the researchers said.

Anyone found with one of these adrenal tumors should be screened to see if their health is at risk, said senior researcher Dr. Wiebke Arlt, director of the University of Birmingham Institute of Metabolism and Systems Research in England.

“People who are found to have an adrenal tumor should undergo assessment for cortisol excess and if they are found to suffer from cortisol overproduction they should be regularly screened for type 2 diabetes and hypertension and receive treatment if appropriate,” Arlt said.

These tumors are usually discovered during imaging scans of the abdomen to treat other illnesses, said Dr. André Lacroix, an endocrinologist at the University of Montreal Hospital Center, who wrote an editorial accompanying the study. Both were published Jan. 4 in the Annals of Internal Medicine.

Adrenal glands primarily produce the hormone adrenaline, but they are also responsible for the production of a number of other hormones, including cortisol, Lacroix said.

Cortisol is called the “fight-or-flight” hormone, and can cause blood sugar levels to rise and blood pressure to surge — usually in response to some perceived bodily threat.

Previous studies had indicated that about 1 in 3 adrenal tumors secrete excess cortisol, and an even lower number caused cortisol levels to rise so high that they affected health, researchers said in background notes.

But this new study of more than 1,300 people with adrenal tumors found that previous estimates were wrong.

About half of these patients had excess cortisol due to their adrenal tumors. Further, more than 15% had levels high enough to impact their health, compared to those with truly benign tumors.

MACS patients were more likely to be diagnosed with high blood pressure, and were as much as twice as likely to be on three or more blood pressure medications.

They also were more likely to have type 2 diabetes, and were twice as likely to require insulin to manage their blood sugar, the study found.

“This study clearly shows that mild cortisol production is more frequent than we thought before, and that the more cortisol you produce, the more likely to you are to have consequences such as diabetes and hypertension,” Lacroix said.

About 70% of people with MACS were women, and most were of postmenopausal age, the researchers said.

“Adrenal tumor-related cortisol excess is an important previously overlooked health issue that particularly affects women after the menopause,” Arlt said.

Lacroix agreed that guidelines should be changed so that people with adrenal tumors are regularly screened.

“Everybody who is found to have an adrenal nodule larger than 1 centimeter needs to be screened to see if they’re producing excess hormone or not,” he said. “That’s very clear.”

A number of medications can reduce cortisol overproduction or block cortisol action, if an adrenal tumor is found to be causing an excess of hormone.

People with severe cortisol excess can even have one of their two adrenal glands removed if necessary, Lacroix said.

“It is quite possible to live completely normally with one adrenal gland,” he said.

Adrenal Fatigue: Faux Diagnosis?

Posted on November 30, 2021 by MaryO

This article is based on reporting that features expert sources.

U.S. News & World Report

Adrenal Fatigue: Is It Real?

You may have heard of so-called ‘adrenal fatigue,’ supposedly caused by ongoing emotional stress. Or you might have come across adrenal support supplements sold online to treat it. But if someone suggests you have the controversial, unproven condition, seek a second opinion, experts say. And if someone tries to sell you dietary supplements or other treatments for adrenal fatigue, be safe and save your money.

Physicians tend to talk about ‘reaching’ or ‘making’ a medical diagnosis. However, when it comes to adrenal fatigue, endocrinologists – doctors who specialize in diseases involving hormone-secreting glands like the adrenals – sometimes use language such as ‘perpetrating a diagnosis,’ ‘misdiagnosis,’ ‘made-up diagnosis,’ ‘a fallacy’ and ‘nonsense.’

About 20 years ago, the term “adrenal fatigue” was coined by Dr. James Wilson, a chiropractor. Since then, certain practitioners and marketers have promoted the notion that chronic stress somehow slows or shuts down the adrenal glands, causing excessive fatigue.

“The phenomenon emerged from the world of integrative medicine and naturopathic medicine,” says Dr. James Findling, a professor of medicine and director of the Community Endocrinology Center and Clinics at the Medical College of Wisconsin. “It has no scientific basis, and there’s no merit to it as a clinical diagnosis.”

An online search of medical billing code sets in the latest version of the International Classification of Diseases, or the ICD-10, does not yield a diagnostic code for ‘adrenal fatigue’ among the 331 diagnoses related either to fatigue or adrenal conditions or procedures.

In a March 2020 position statement, the American Association of Clinical Endocrinologists and American College of Endocrinology addressed the use of adrenal supplements “to treat common nonspecific symptoms due to ‘adrenal fatigue,’ an entity that has not been recognized as a legitimate diagnosis.”

The position statement warned of known and unknown health risks of off-label use and misuse of hormones and supplements in patients without an established endocrine diagnosis, as well as unnecessary costs to patients and the overall health care system.

Study after study has refuted the legitimacy of adrenal fatigue as a medical diagnosis. An August 2016 systematic review combined and analyzed data from 58 studies on adrenal fatigue including more than 10,000 participants. The conclusion in a nutshell: “Adrenal fatigue does not exist,” according to review authors in the journal BMC Endocrine Disorders.

Adrenal Action

You have two adrenal glands in your body. These small triangular glands, one on top of each kidney, produce essential hormones such as aldosterone, cortisol and male sex hormones such as DHEA and testosterone.

Cortisol helps regulate metabolism: How your body uses fat, protein and carbohydrates from food, and cortisol increases blood sugar as needed. It also plays a role in controlling blood pressure, preventing inflammation and regulating your sleep/wake cycle.

As your body responds to stress, cortisol increases. This response starts with signals between two sections in the brain: The hypothalamus and the pituitary gland, which act together to release a hormone that stimulates the adrenal glands to make cortisol. This interactive unit is called the hypothalamic pituitary adrenal axis.

While some health conditions really do affect the body’s cortisol-making ability, adrenal fatigue isn’t among them.

“There’s no evidence to support that adrenal fatigue is an actual medical condition,” says Dr. Mary Vouyiouklis Kellis, a staff endocrinologist at Cleveland Clinic. “There’s no stress connection in the sense that someone’s adrenal glands will all of a sudden just stop producing cortisol because they’re so inundated with emotional stress.”

If anything, adrenal glands are workhorses that rise to the occasion when chronic stress occurs. “The last thing in the body that’s going to fatigue are your adrenal glands,” says Dr. William F. Young Jr., an endocrinology clinical professor and professor of medicine in the Mayo Clinic College of Medicine at Mayo Clinic in Rochester, Minnesota. “Adrenal glands are built for stress – that’s what they do. Adrenal glands don’t fatigue. This is made up – it’s a fallacy.”

The idea of adrenal glands crumbling under stress is “ridiculous,” Findling agrees. “In reality, if you take a person and subject them to chronic stress, the adrenal glands don’t shut down at all,” Findling says. “They keep making cortisol – it’s a stress hormone. In fact, the adrenal glands are just like the Energizer Bunny – they just keep going. They don’t stop.”

Home cortisol tests that allow consumers to check their own levels can be misleading, Findling says. “Some providers who make this (adrenal fatigue) diagnosis, provide patients with testing equipment for doing saliva cortisol levels throughout the day,” he says. “And then, regardless of what the results are, they perpetrate this diagnosis of adrenal fatigue.”

Saliva cortisol is a legitimate test that’s frequently used in diagnosing Cushing’s syndrome, or overactive adrenal glands, Findling notes. However, he says, a practitioner pursuing an adrenal fatigue diagnosis could game the system. “What they do is: They shape a very narrow normal range, so narrow, in fact, that no normal human subject could have all their saliva cortisol (levels) within that range throughout the course of the day,” he says. “Then they convince the poor patients that they have adrenal fatigue phenomena and put them on some kind of adrenal support.”

Loaded Supplements

How do you know what you’re actually getting if you buy a dietary supplement marketed for adrenal fatigue or ‘adrenal support’ use? To find out, researchers purchased 12 such supplements over the counter in the U.S.

Laboratory tests revealed that all supplements contained a small amount of thyroid hormone and most contained at least one steroid hormone, according to the study published in the March 2018 issue of Mayo Clinic Proceedings. “These results may highlight potential risks for hidden ingredients in unregulated supplements,” the authors concluded.

Supplements containing thyroid hormones or steroids can interact with a patient’s prescribed medications or have other side effects.

“Some people just assume they have adrenal fatigue because they looked it up online when they felt tired and they ultimately buy these over-the-counter supplements that can be very dangerous at times,” Vouyiouklis Kellis says. “Some of them contain animal (ingredients), like bovine adrenal extract. That can suppress the pituitary axis. So, as a result, your body stops making its own cortisol or starts making less of it, and as a result, you can actually worsen the condition rather than make it better.”

Any form of steroid from outside the body, whether a prescription drug like prednisone or extract from cows’ adrenal glands, “can shut off the pituitary,” Vouyiouklis Kellis explains. “Because it’s signaling to the pituitary like: Hey, you don’t need to stimulate the adrenals to make cortisol, because this patient is taking it already. So, as a result, the body ultimately doesn’t produce as much. And, so, if you rapidly withdraw that steroid or just all of a sudden decide not to take it anymore, then you can have this acute response of low cortisol.”

Some adrenal support products, such as herbal-only supplements, may be harmless. However, they’re unlikely to relieve chronic fatigue.

Fatigue: No Easy Answers

If you’re suffering from ongoing fatigue, it’s frustrating. And you’re not alone. “I have fatigue,” Young Jr. says. “Go to the lobby any given day and say, ‘Raise your hand if you have fatigue.’ Most of the people are going to raise their hands. It’s a common human symptom and people would like an easy answer for it. Usually there’s not an easy answer. I think ‘adrenal fatigue’ is attractive because it’s like: Aha, here’s the answer.”

There aren’t that many causes of endocrine-related fatigue, Young Jr. notes. “Hypothyroidism – when the thyroid gland is not working – is one.” Addison’s disease, or adrenal insufficiency, can also lead to fatigue among a variety of other symptoms. Established adrenal conditions – like adrenal insufficiency – need to be treated.

“In adrenal insufficiency, there is an intrinsic problem in the adrenal gland’s inability to produce cortisol,” Vouyiouklis Kellis explains. “That can either be a primary problem in the adrenal gland or an issue with the pituitary gland not being able to stimulate the adrenal to make cortisol.”

Issues can arise even with necessary medications. “For example, very commonly, people are put on steroids for various reasons: allergies, ear, nose and throat problems,” Vouyiouklis Kellis says. “And with the withdrawal of the steroids, they can ultimately have adrenal insufficiency, or decrease in cortisol.”

Opioid medications for pain also result in adrenal sufficiency, Vouyiouklis Kellis says, adding that this particular side effect is rarely discussed. People with a history of autoimmune disease can also be at higher risk for adrenal insufficiency.

Common symptoms of adrenal insufficiency include:

  • Fatigue.
  • Weight loss.
  • Decreased appetite.
  • Salt cravings.
  • Low blood pressure.
  • Abdominal pain.
  • Nausea, vomiting or diarrhea.
  • Muscle weakness.
  • Hyperpigmentation (darkening of the skin).
  • Irritability.

Medical tests for adrenal insufficiency start with blood cortisol levels, and tests for the ACTH hormone that stimulates the pituitary gland.

“If the person does not have adrenal insufficiency and they’re still fatigued, it’s important to get to the bottom of it,” Vouyiouklis Kellis says. Untreated sleep apnea often turns out to be the actual cause, she notes.

“It’s very important to tease out what’s going on,” Vouyiouklis Kellis emphasizes. “It can be multifactorial – multiple things contributing to the patient’s feeling of fatigue.” The blood condition anemia – a lack of healthy red blood cells – is another potential cause.

“If you are fatigued, do not treat yourself,” Vouyiouklis Kellis says. “Please seek a physician or a primary care provider for evaluation, because you don’t want to go misdiagnosed or undiagnosed. It’s very important to rule out actual causes that would be contributing to symptoms rather than ordering supplements online or seeking an alternative route like self-treating rather than being evaluated first.”

A Case of Cushing’s Disease Presenting with Isolated Suicidal Attempt

Posted on November 2, 2021 by MaryO

Abstract

Cushing’s disease is an abnormal secretion of ACTH from the pituitary that causes an increase in cortisol production from the adrenal glands. Resultant manifestations from this excess in cortisol include multiple metabolic as well as psychiatric disturbances which can lead to significant morbidity and mortality. In this report, 23-year-old woman presented to mental health facility with history of severe depression and suicidal ideations. During evaluation, she found to have Cushing’s disease, which is unusual presentation. She had significant improvement in her symptoms with reduction of antidepressant medications after achieving eucortisolism. Cushing syndrome can present with wide range of neuropsychiatric manifestations including major depression. Although presentation with suicidal depression is unusual. Early diagnosis and prompt management of hypercortisolsim may aid in preventing or lessening of psychiatric symptoms The psychiatric and neurocognitive disorders improve after disease remission (the normalization of cortisol secretion), but some studies showed that these disorders can partially improve, persist, or exacerbate, even long-term after the resolution of hypercortisolism. The variable response of neuropsychiatric disorders after Cushing syndrome remission necessitate long term follow up.

Introduction

Endogenous Cushing syndrome is a complex disorder caused by chronic exposure to excess circulating glucocorticoids. It has a wide range of clinical signs and symptoms as a result of the multisystem effects caused by excess cortisol.1

The hypercortisolism results in several complications that include glucose intolerance, diabetes, hypertension, dyslipidemia, thromboembolism, osteoporosis, impaired immunity with increased susceptibility to infection as well as neuropsychiatric disorders.2,3

Cushing syndrome presents with a wide variety of neuro-psychiatric manifestations like anxiety, major depression, mania, impairments of memory, sleep disturbance, and rarely, suicide attempt as seen in this case.2,4

The mechanism of neuropsychiatric symptoms in Cushing’s syndrome is not fully understood, but multiple proposed theories have been reported, one of which is the direct brain damage secondary to excess of glucocorticoids.5

Case Report

A 23-year-old female presented to Al-Amal complex of mental health in Riyadh, Saudi Arabia with history of suicidal tendencies and 1 episode of suicidal attempt which was aborted because of religious reasons. She reported history of low mood, having disturbed sleep, loss of interest, and persistent feeling of sadness for 4 months. She also reported history of weight gain, facial swelling, hirsutism, and irregular menstrual cycle with amenorrhea for 3 months. She was prescribed fluoxetine 40 mg and quetiapine 100 mg. She was referred to endocrinology clinic at King Fahad Medical City, Riyadh for evaluation and management of possible Cushing syndrome as the cause of her abnormal mental health.

She was seen in the endocrinology clinic where she reported symptoms as mentioned above in addition to headache, acne, and proximal muscle weakness.

On examination her vital signs were normal. She had depressed affect, rounded face with acne and hirsutism, striae in the upper limb, and abdomen with proximal muscle weakness (4/5).

Initial investigations showed that 24 hour urinary free cortisol was more than 633 µg which is more than 3 times upper limit of normal (this result was confirmed on second sample with level more than 633 µg/24 hour), cortisol level of 469 nmol/L after low dose 1 mg-dexamethasone suppression test and ACTH level of 9.8 pmol/L. Levels of other anterior pituitary hormones tested were within normal range. She also had prediabetes with HbA1c of 6.1 and dyslipidemia. Serum electrolytes, renal function and thyroid function tests were normal.

MRI pituitary showed left anterior microadenoma with a size of 6 mm × 5 mm.

There is no abnormal signal intensity or abnormal enhancing lesion seen.

No further hormonal work up or inferior petrosal sinus sampling were done as the tumor size is 6 mm and ACTH level consistent with Cushing’s disease (pituitary source). She was referred to neurosurgery and underwent trans-sphenoidal resection of the tumor. Histopathology was consistent with pituitary adenoma and positive for ACTH. Her repeated cortisol level after tumor resection was less than 27 and ACTH 2.2 with indicated excellent response to surgery.

She was started on hydrocortisone until recovery of her hypothalamic pituitary adrenal axis documented by normal morning cortisol 3 months after surgery (Table 1).

During follow up with psychiatry her depressive symptoms improved but not resolved and she was able to stop fluoxetine 5 months post-surgery. Currently she is maintained on quetiapine 100 mg with significant improvement in her psychiatric symptoms.

Currently she is in remission from Cushing’s disease based on the normal level of repeated 24 hour urinary free cortisol and with an over-all improvement in her metabolic profile.

Discussion

Cushing syndrome is a state of chronic hypercortisolism due to either endogenous or exogenous sources. Glucocorticoid overproduction by adrenal gland can be adrenocorticotropic (ACTH) hormone dependent which represent most of the cases and ACTH independent.6 To the best of our knowledge this is the first case documented in Saudi Arabia.

There are multiple theories behind the neuropsychiatric manifestations in Cushing syndrome. These include increased stress response leading to behavioral changes, prolonged cortisol exposure leading to decreased brain volume especially in the hippocampus, reduced dendritic mass, decreased glial development, trans-cellular shift of water and synaptic loss, and excess glucocorticoid levels inhibiting neurogenesis and promoting neuronal tendency to toxic insult.3,7

In this report, the patient presented with severe depression with suicidal attempt. She had significant improvement in her symptoms with reduction of antidepressant medications but her depression persisted despite remission of Cushing disease. A similar case has been reported by Mokta et al,1 about a young male who presented with suicidal depression as initial manifestation of Cushing disease. As opposed to the present case he had complete remission of depression within 1 month of resolution of hypercortisolism.

In general, psychiatric and neurocognitive disorders secondary to Cushing syndrome improves after normalization of cortisol secretion, but some studies showed that these disorders can partially improve, persist, or exacerbate, even long-term after the resolution of hypercortisolism. This may be due to persistence hypercortisolism creating toxic brain effects that occur during active disease.2,8 Similar patients need to be followed up for mental health long after Cushing syndrome has been resolved.

Conclusion

Depression is a primary psychiatric illness, that is, usually not examined for secondary causes. Symptoms of depression and Cushing syndrome overlap, so diagnosis and treatment of Cushing disease can be delayed. Early diagnosis and prompt management of hypercortisolsim may aid in preventing or lessening psychiatric symptoms. The variable neuropsychiatric disorders associated with Cushing syndrome post-remission necessitates long term follow up.

Researchers Report Rare Case of Cushing’s Caused by Bilateral Adrenal Tumors

Posted on July 8, 2019 by MaryO

Cases of adrenocorticotropic hormone (ACTH)-independent Cushing’s syndrome are often caused by unilateral tumors in the adrenal glands, but Indian researchers have now reported a rare case where the condition was caused by tumors in both adrenal glands.

Fewer than 40 cases of bilateral tumors have been reported so far, but an accurate diagnosis is critical for adequate and prompt treatment. Sampling the veins draining the adrenal glands may be a good way to diagnose the condition, researchers said.

The study, “Bilateral adrenocortical adenomas causing adrenocorticotropic hormone-independent Cushing’s syndrome: A case report and review of the literature,” was published in the World Journal of Clinical Cases.

Cushing’s syndrome, a condition characterized by excess cortisol in circulation, can be divided into two main forms, depending on ACTH status. Some patients have tumors that increase the amount of ACTH in the body, and this hormone will act on the adrenal glands to produce cortisol in excess. Others have tumors in the adrenal glands, which produce excess cortisol by themselves, without requiring ACTH activation. This is known as ACTH-independent Cushing’s syndrome.

Among the latter, the disease is mostly caused by unilateral tumors — in one adrenal gland only —  with cases of bilateral tumors being extremely rare in this population.

Now, researchers reported the case of a 31-year-old Indian woman who developed ACTH-independent Cushing’s syndrome because of tumors in both adrenal glands.

The patient complained of weight gain, red face, moon face, bruising, and menstrual irregularity for the past two years. She recently had been diagnosed with high blood pressure and had started treatment the month prior to the presentation.

A physical examination confirmed obesity in her torso, moon face, buffalo hump, thin skin, excessive hair growth, acne, swollen legs and feet, and skin striae on her abdomen, arms, and legs.

Laboratory examinations showed that the woman had an impaired tolerance to glucose, excess insulin, and elevated cortisol in both the blood and urine. Consistent with features of Cushing’s syndrome, cortisol levels had no circadian rhythm and were non-responsive to a dexamethasone test, which in normal circumstances lowers cortisol production.

Because ACTH levels were within normal levels, researchers suspected an adrenal tumor, which led them to conduct imaging scans.

An abdominal computed tomography (CT) scan showed adrenal adenomas in both adrenal glands (right: 3.1 cm × 2.0 cm × 1.9 cm; left: 2.2 cm × 1.9 cm × 2.1 cm). A magnetic resonance imaging (MRI) scan showed that the pituitary gland (which normally produces ACTH) was normal.

To determine whether both adrenal tumors were producing cortisol, researchers sampled the adrenal veins and compared their cortisol levels to those of peripheral veins. They found that the left adrenal gland was producing higher amounts of cortisol, thought the right adrenal gland was also producing cortisol in excess.

“Our case indicates that adrenal vein [blood] sampling might be useful for obtaining differential diagnoses” in cases of Cushing’s syndrome, researchers stated. Also, they may help design a surgical plan that makes much more sense.”

The tumors were surgically removed — first the left, and three months later the right — which alleviated many of her symptoms. She also started prednisolone treatment, which helped resolve many disease symptoms.

“Bilateral cortisol-secreting tumors are a rare cause of Cushing’s syndrome,” researchers said. So when patients present bilateral adrenal lesions, “it is crucial to make a definitive diagnosis before operation since various treatments are prescribed for different causes,” they said.

The team recommends that in such cases the two tumors should not be removed at the same time, as this approach may cause adrenal insufficiency and the need for glucocorticoid replacement therapy.

Laparoscopic Removal of Adrenal Glands Safe for Obese Cushing’s Patients

Posted on March 9, 2019 by MaryO

Laparoscopic adrenalectomy — a minimally invasive procedure that removes the adrenal glands through a tiny hole in the abdomen — can be safely performed in obese patients with Cushing’s syndrome, a retrospective study reports.

The surgery resolved symptoms in 95% of cases, reducing cortisol levels, lowering blood pressure, and leading to a significant loss of weight in morbidly obese patients.

The study, “Minimally invasive approach to the adrenal gland in obese patients with Cushing’s syndrome,” was published in the journal Minimally Invasive Therapy & Allied Technologies.

Cushing’s syndrome results from the prolonged secretion of excess cortisol, the major glucocorticoid hormone. While most cases are caused by tumors in the pituitary gland, up to 27% result from tumors in the adrenal glands.

In these cases, the standard therapeutic strategy is to remove one or both adrenal glands, a surgical procedure called adrenalectomy. However, because glucocorticoids are key hormones regulating fat metabolism, Cushing’s syndrome patients are known to be prone to obesity, a feature that is often associated with post-operative complications.

In this study, researchers aimed to compare the outcomes of morbidly obese patients versus the mildly obese and non-obese who underwent a minimally invasive procedure to remove their adrenal glands.

The approach, called laparoscopic adrenalectomy, inserts tiny surgical tools through a small hole in the abdomen, along with a camera that helps guide the surgeon.

The study included 228 patients (mean age 53.4 years). Of them, 62 were non-obese, 87 were moderately obese, and 79 were considered morbidly obese. There were 121 patients with tumors in the right adrenal gland, 96 in the left gland, and 11 in both glands.

High blood pressure was the most common symptom, affecting 66.7% of the participants.

Surgery lasted 101 minutes on average, and patients remained in the hospital for a median 4.3 days afterward. Six patients had to be converted into an open surgery because of uncontrollable loss of blood or difficulties in the procedure. Post-surgery complications, most of which were minor, were seen in seven patients.

One patient had blood in the peritoneal cavity and had to have surgery again; another patient had inflammation of the pancreas that required a longer admission.

The analysis showed no statistical differences among the three groups regarding the length of surgery, length of stay in the hospital, or the rate of conversion into open surgery.

However, in obese women, surgeons chose a different surgical incision when removing the left adrenal gland, “suggesting that the distribution of visceral fat in these patients could constitute a drawback for the [standard] approach,” researchers said.

After the surgery, 95% of patients saw their symptoms resolve, including cortisol levels, high blood pressure, and glucose metabolism, and none had a worsening of symptoms in the 6.3 years of follow-up. Obese patients also showed a significant reduction in their weight — 2 kg by 18 months, and 5 kg by the end of follow-up.

Overall, “laparoscopic adrenalectomy is safe and feasible in obese patients affected with Cushing’s disease and it can lead to the resolution of the related symptoms,” researchers said.

The benefits of the surgery in patients with Cushing’s syndrome “could be extended to the improvements and in some cases to the resolution of hypercortisolism related symptoms (i.e. hypertension or even morbid obesity),” the study concluded.
