Cushing’s disease is a rare condition that is caused when the body is exposed to high hormone cortisol for a long period. Also known as hypercortisolism, this disease is usually caused when the body produces too much cortisol hormone. Cortisol is a hormone that is essential for the smooth functioning of the body and is made by the adrenal glands. It largely affects body tissues and controls the body’s use of nutrition such as proteins and fats. It is necessary to help an individual deal with situations that include illnesses and stress. Cushing’s disease can cause several complications such as an increase in blood pressure, loss of bone density and in some cases Type 2 diabetes. The Cushing’s disease symptoms depend on the levels of cortisol produced in the body. Here are few typical Cushing’s disease symptoms that may be experienced by an individual who suffers from the condition: Gain in body weight – Increase in body weight is one of the most common Cushing’s disease symptoms. An individual begins to suddenly bloat, especially in the upper parts of the body. This includes the arms, chest, and abdomen. Back-hump – A lump begins to form in the upper portion of the back, between the shoulders.
