Why Was This Woman Gaining Weight Despite Her Diet?

“I just can’t seem to lose weight,” the 59-year-old woman said quietly. She had tried everything, she told the young doctor, who was training to be an endocrinologist at Mount Sinai Hospital in New York City. Weight Watchers. Exercise. She ate more vegetables, less fat, then fewer carbs. But still she was gaining weight, 30 pounds during the past seven months, including 12 in the past two weeks. She had never been skinny, she continued, but shapely. In her mid-40s, she started gaining weight, slowly at first, then rapidly. She was considering bariatric surgery, but she wanted to make sure she wasn’t missing something obvious. She had low thyroid hormones and had to take medication. Could her thyroid be off again?

The doctor asked her about symptoms associated with a low thyroid-hormone level. Fatigue? Yes, she was always tired. Changes in her hair or skin? No. Constipation? No. Do you get cold easier? Never. Indeed, these days she usually felt hot and sweaty.

It was probably not the thyroid, the doctor said. She asked if the woman had any other medical problems. She had high blood pressure and high cholesterol — both well controlled with medications. She also had obstructive sleep apnea, a disorder in which the soft tissue at the back of the throat collapse during sleep, cutting off air flow and waking the person many times throughout the night. She had a machine that helped keep her airway open, and she used it every night. She also had back pain, knee pain and carpal-tunnel syndrome. The pain was so bad that she had to retire from her job years before she was ready.

Big, Bigger, Biggest

The doctor examined her, then went to get Dr. Donald Smith, an endocrinologist and director of lipids and metabolism at Mount Sinai’s cardiovascular institute. After hearing a summary of the case, Smith asked the patient if she had anything to add. She did: She didn’t understand why she was getting so much bigger. Her legs were huge. She used to have nice ankles, but now you could hardly see them. Her doctor had given her a diuretic, but it hadn’t done a thing. Everything was large — her feet, her hands, even her face seemed somehow bigger. She hardly recognized the woman in the mirror. Her doctors just encouraged her to keep trying to lose weight.

Worth a Thousand Words

“Let me show you a picture,” she said suddenly and reached over to her purse. The patient’s sister had made a comment recently that led the patient to wonder whether the changes she saw in the mirror were more than simple aging. The patient pulled out a photograph of an attractive middle-aged woman and handed it to Smith. That was me eight years ago, she told him. Looking at the two faces, it was hard to believe they belonged to the same woman. Smith suspected this was something more than the extra pounds.

Two possibilities came to mind. Each was a disease of hormonal excess; each caused rapid weight gain. The first was Cushing’s disease, caused by overproduction of one of the fight-or-flight hormones, cortisol. The doctor looked at the patient, seeking clues. On her upper back, just below her neck, the woman had a subtle area of enlargement. This discrete accumulation of fat, called a buffalo hump, can occur with normal weight gain but is frequently seen in patients with Cushing’s. Do you bruise more easily these days? he asked. Cushing’s makes the skin fragile. No, she said. Did she have stretch marks on her stomach from the weight gain? The rapid expansion of the abdomen can cause the fragile skin to develop dark purple stretch lines. No. So maybe it wasn’t Cushing’s.

Froedtert and MCW researchers investigate Cushing syndrome incidence in bariatric surgery patients

Researchers at the Medical College of Wisconsin determined that Cushing syndrome, an endocrine disorder, may be the potential cause for weight gain and metabolic complications for patients who have undergone bariatric surgery for obesity. The study, published in the journal Obesity Surgery, was conducted by Ty B. Carroll, MD, assistant professor of endocrinology; James W. Findling, MD, FACP, professor of endocrinology ; and Bradley R. Javorsky, MD, assistant professor of endocrinology. The physicians practice at Froedtert Hospital in Wauwatosa and Community Memorial Hospital in Menomonee Falls.

Cushing syndrome can occur when the human body is exposed to high levels of cortisol for an extended period of time. Cortisol is a hormone in the body which affects blood pressure regulation and cardiovascular system functions. Cortisol also helps regulate the body’s conversion of proteins, carbohydrates and fats from diet into usable energy. However, when the level of cortisol becomes too high, Cushing syndrome can develop.

Cushing syndrome is associated with a variety of symptoms including weight gain and fatty tissue deposits in the body. According to the American Association of Neurological Surgeons, 10 to 15 million people are affected each year by Cushing syndrome.

Bariatric surgery is a procedure performed to help with extreme cases of obesity. Weight loss is achieved by reducing the size of the stomach with a gastric band, removal of a portion of the stomach or resecting and rerouting the small intestine to a small stomach pouch. Bariatric surgery is often used as an option for individuals unable to lose weight through diet and exercise, or have serious health problems caused by obesity.

According to the American Society for Metabolic and Bariatric Surgery, 179,000 bariatric surgeries were performed in the U.S. in 2013. However, despite successes in normal weight loss cases, bariatric surgery does not provide long term weight loss for individuals diagnosed with Cushing syndrome. Cushing syndrome often goes undiagnosed as a potential cause for weight gain and metabolic complications until after the surgery is performed.

MCW researchers in this study analyzed the incidence of Cushing syndrome in patients who underwent bariatric surgery for weight loss. During the investigation, the researchers performed a retrospective chart review on a series of 16 patients diagnosed with Cushing syndrome from five tertiary care centers in the U.S. who underwent bariatric surgery. The results from the study found 12 of the analyzed patients were not diagnosed with Cushing syndrome prior to their bariatric surgery. The remaining four patients had Cushing syndrome surgery prior to bariatric surgery, without recognition that their Cushing syndrome was persistent until after the weight loss surgery. The findings from the research indicate that Cushing syndrome may be often overlooked in patients undergoing bariatric surgery.

According to the researchers, testing for Cushing syndrome should be performed prior to bariatric surgery in patients with persistent hypertension, diabetes mellitus or excessive weight regain.
