The symptoms include weight loss, poor appetite, nausea and vomiting, fatigue, darkening of skin only in primary adrenal insufficiency , abdominal pain, among other. The causes of primary adrenal insufficiency may include autoimmune disorders, fungal and other infections, cancer rarely , and genetic factors.

Although adrenal insufficiency usually develops over time, it can also appear suddenly as an acute adrenal failure adrenal crisis. It has similar symptoms, but the consequences are more serious, including life-threatening shock, seizures, and coma. These may develop if the condition is left untreated. Adrenal insufficiency can also result from a genetic disorder called congenital adrenal hyperplasia.

Children who are born with this disorder are missing an essential enzyme necessary to produce cortisol, aldosterone or both. At the same time, they often experience excess of androgen, which may lead to male characteristics in girls and precocious puberty in boys. Congenital adrenal hyperplasia can remain undiagnosed for years depending on the severity of the enzyme deficiency.

In more severe cases, infants may suffer from ambiguous genitalia, dehydration, vomiting and failure to thrive. Sometimes, adrenal glands may develop nodules that produce too much of certain hormones. Nodules 4 centimeters or larger and nodules that show certain features on imaging increase suspicion for malignancy. Both benign and cancerous nodules may produce excessive amounts of certain hormones, which is referred to as a functional nodule.

Functional tumors, malignant tumors or nodules greater than 4 centimeters are recommended to be referred for surgical evaluation. Cushing syndrome results from excessive production of cortisol from the adrenal glands.

The symptoms may include weight gain and fatty deposits in certain areas of the body, such as the face, below the back of the neck called a buffalo hump and in the abdomen; thinning arms and legs; purple stretch marks on the abdomen; facial hair; fatigue; muscle weakness; easily bruised skin; high blood pressure; diabetes; and other health issues.

Excess cortisol production can also be triggered by overproduction of ACTH by a benign tumor in the pituitary gland or tumor elsewhere in the body.
