Cushing's syndrome
Cushing's syndrome is a hormonal disorder caused by prolonged exposure to high levels of cortisol in the body. It often leads to distinct physical changes like a rounded face and fatty hump between the shoulders.
Overview
Cushing's syndrome is a hormonal disorder caused by prolonged exposure to high levels of cortisol in the body. It often leads to distinct physical changes like a rounded face and fatty hump between the shoulders.
Understand this condition
The adrenal glands sit on top of the kidneys and produce cortisol to manage stress and metabolism. In Cushing's syndrome, the body loses its ability to regulate this hormone, keeping levels constantly high. This flood of cortisol forces the body to store fat and break down muscle.
Why it happens
The condition is usually triggered by a tumor or by taking steroid medication for other illnesses. Excess cortisol causes the body to over-process sugars and fats while weakening structural tissues. Without treatment, it can lead to chronic heart disease and brittle bones.
