Dear Dr. Roach: I had apoplexy, a ruptured pituitary tumor, developed panhypopituitarism, then adrenal insufficiency. I am doing fairly well with cortisol replacement, thyroid supplement and oral diabetic medicine.

My problem is exhaustion that comes on very easily. I have other ailments to blame, too — chronic pain from fibromyalgia and tendinitis. I am 67. I am still able to work. Is adrenal fatigue a real issue, and if so, what can be done about it? — S.M.

Answer: The term “adrenal fatigue” is increasingly used, and not always correctly — or, at least, it is used in cases where it’s not clear if that is actually the case. But let me start by discussing what has happened to you. Pituitary apoplexy is bleeding into the pituitary gland, usually into a pituitary tumor, as in your case. This may cause severe headaches and vision changes, and often it prevents the pituitary from making the many important hormones that control the endocrine glands and regulate the body.

For example, without TSH from the pituitary gland, the thyroid won’t release thyroid hormone, and importantly, the adrenal gland can’t make cortisol without the influence of ACTH from the pituitary.

Rather than trying to replace TSH, ACTH and the other pituitary hormones, it is easier to directly replace the hormones made by the adrenal, thyroid and gonads. That’s why you are taking cortisol and thyroid hormone, and why younger women take estrogen and men testosterone. Although there is nothing wrong with your thyroid and adrenal glands, they simply won’t work unless stimulated.

Inadequate adrenal function from any cause leads to profound fatigue, and in the presence of severe stress, such as surgery or major infection, the body’s need for cortisol increases dramatically. Unless enough adrenal hormone is given in response, the result can be an immediate life-threatening condition called an Addisonian crisis.
