Glucocorticoid Resistance: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Glucocorticoid Resistance?
An endocrinologist, a doctor who specializes in hormones, usually leads care. A gastroenterologist may be involved when inflammatory bowel disease is not responding to steroids. Primary care doctors often start the evaluation and refer to the right specialist. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is glucocorticoid resistance?
Glucocorticoid resistance is a rare condition in which the body stops responding properly to cortisol, the natural stress hormone, and to steroid medicines that act like it. The adrenal glands keep making extra cortisol to compensate, which can affect many parts of the body.
Cortisol is a hormone that helps control blood sugar, blood pressure, inflammation, and the sleep-wake cycle. Glucocorticoids are drugs that copy cortisol's action and are used to calm inflammation in conditions such as asthma and arthritis. In glucocorticoid resistance, the receptors that cortisol normally attaches to do not work properly, so the body makes more and more cortisol. The result is weak cortisol action in the body, while other hormones made by the adrenal glands rise too high.
Symptoms
Symptoms vary from person to person. Some people have tiredness or muscle weakness. Others develop effects of the extra hormones the body makes, such as high blood pressure, low potassium, acne, extra body hair, or irregular periods. Many people have no symptoms at all.
Causes and who gets it
Most cases come from changes in the gene for the cortisol receptor, and these changes can run in families. Some cases are linked to long-term inflammation. It is very rare and can appear at any age.
How doctors diagnose it
Doctors start with blood and urine tests that measure cortisol and related hormones, often repeating them. Genetic testing can confirm an inherited form, and doctors rule out other conditions, such as Cushing syndrome.
Treatment
There is no cure, so treatment focuses on lowering excess cortisol and managing its effects. Doctors often give a steroid medicine such as dexamethasone to quiet the signal that makes extra hormones, and they treat related problems such as high blood pressure and low potassium.
When to see a doctor
See a doctor if you have ongoing tiredness, muscle weakness, unexplained weight gain, high blood pressure, or an inflammatory condition that does not improve with steroid treatment. Get help promptly for very high blood pressure or confusion.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works alongside insurance. Either can order hormone tests, monitor blood pressure and blood sugar, and coordinate care among specialists.
Common questions
Is glucocorticoid resistance the same as Cushing syndrome?
No. Cushing syndrome happens when the body is exposed to too much cortisol and shows the full effects. In glucocorticoid resistance, tissues respond weakly, so the body makes extra cortisol.
Can steroid medicines still work for me if I have this condition?
They may work less well because tissues respond weakly. Doctors can adjust the treatment plan and consider other medicines.
Is this condition passed down in families?
The inherited form runs in families and comes from changes in the gene for the cortisol receptor. A doctor may suggest genetic or hormone testing if a close relative has it.
Can it be cured?
There is no cure that removes the underlying cause. Treatment can lower excess cortisol and manage its effects, and many people improve with proper care.
