Pituitary & Adrenal

The pituitary and adrenal glands are small, but they have a significant effect on the body. The pituitary gland sits at the base of the brain and helps regulate several other hormone-producing glands. The adrenal glands sit on top of the kidneys and make hormones that help control stress response, blood pressure, metabolism, salt balance, and other essential functions. When these glands produce too much or too little hormone, symptoms can be difficult to identify because they often overlap with many other medical conditions.

At The Endocrinology Group, our clinicians evaluate pituitary and adrenal concerns for patients in Falls Church, Arlington, and across Northern Virginia. These conditions can be complex and may require careful interpretation of symptoms, lab results, imaging, medication history, and long-term monitoring. Our role is to help patients understand what may be happening hormonally and what next steps may be appropriate.

Pituitary disorders may involve hormone deficiencies, hormone excess, pituitary tumors, elevated prolactin, growth hormone concerns, adrenal signaling problems, thyroid signaling problems, reproductive hormone changes, or water balance disorders. A pituitary growth is often benign, but it can still affect hormone function or, in some cases, vision if it presses on nearby structures. Patients may be referred after abnormal labs, MRI findings, headaches, vision changes, menstrual changes, low testosterone, infertility concerns, unexplained fatigue, or symptoms suggesting hormone imbalance.

An adrenal evaluation may involve concerns such as adrenal insufficiency, Cushing’s syndrome, adrenal nodules, aldosterone excess, cortisol abnormalities, or androgen-related symptoms. Adrenal insufficiency occurs when the body does not make enough cortisol or does not receive the proper hormonal signal to make cortisol. Symptoms may include fatigue, weakness, weight loss, low blood pressure, dizziness, nausea, abdominal discomfort, salt cravings in some cases, and low blood sugar symptoms. Because cortisol is essential during illness and physical stress, true adrenal insufficiency requires proper diagnosis, education, and ongoing management.

Cushing’s syndrome is a condition caused by too much cortisol over time. Symptoms may include weight gain, easy bruising, muscle weakness, high blood pressure, high blood sugar, bone loss, mood changes, and changes in body shape. One of the challenges with cortisol disorders is that many symptoms are common and can have several possible causes. Testing must be selected and timed carefully, and results often need expert interpretation.

A visit for pituitary or adrenal concerns typically begins with a detailed history. Your clinician may ask about symptoms, medication use, steroid exposure, prior surgeries, imaging results, menstrual or reproductive history, blood pressure changes, weight changes, headaches, vision symptoms, and family history. Depending on the concern, testing may include morning hormone levels, stimulation or suppression testing, urine testing, saliva testing, electrolyte testing, or imaging review. The exact approach depends on the suspected condition.

Treatment varies widely. Some pituitary or adrenal disorders are monitored over time, while others require medication, hormone replacement, surgery referral, imaging surveillance, or coordination with additional specialists. Patients with adrenal insufficiency may need education about daily hormone replacement and what to do during illness or physical stress. Patients with pituitary tumors may need periodic MRI review, lab monitoring, or referral to a pituitary surgeon or other specialist if needed.

Medication history is particularly important in adrenal evaluation. Steroid tablets, inhalers, creams, injections, and certain other treatments can influence cortisol testing or adrenal function. Patients may not always think of these as relevant to an endocrine visit, but they can be essential for accurate interpretation. Your clinician may ask about current and past steroid use, recent illness, surgeries, hospitalizations, and any emergency symptoms such as fainting, severe vomiting, dehydration, or confusion.

For adrenal nodules, the question is often whether the nodule is making excess hormone or whether it has features that require additional imaging follow-up. Many adrenal findings are discovered incidentally during scans done for other reasons. Endocrine evaluation helps determine whether the finding is clinically important and what monitoring is reasonable.

If you have abnormal pituitary or adrenal labs, a pituitary or adrenal finding on imaging, symptoms of cortisol imbalance, concerns about adrenal insufficiency, or a complex hormone concern that needs endocrine evaluation, The Endocrinology Group provides pituitary and adrenal disorder care in Falls Church and Arlington, VA.
