Basic definitions of a broad and thorough (though certainly not exhaustive) list of endocrine disorders.


Occurs in adults: caused by a benign pituitary tumor (adenoma).


Occurs in children: caused by a benign pituitary tumor (adenoma).

Empty Sella Syndrome

May result in loss of pituitary functions: ceasing of menstrual periods, infertility, fatigue, and intolerance to stress/infection.


Milky discharge from the breasts of men or women who are not breastfeeding


Inhibited production of one or many of the following: GH, LH, FSH, TSH and ACTH

Addison's Disease

Feel weak, tired, and dizzy when standing up after sitting or lying down and may develop dark skin patches.

Congenital Adrenal Hyperplasia

Too much salt and water are lost in the urine, genital anamolies


The fatty covering (myelin sheath) on nerve fibers in the brain is lost, and the adrenal gland degenerates, leading to progressive neurological disability and death.

Conn's Disease

Hypokalemia, increased blood pH (alkalosis), hypertension, excess aldosterone

Cushing's Syndrome

Obesity, increased fat in the neck and shoulder area, and thin fragile skin that bruises easily and heals slowly.

Diabetes Mellitus Type I

The body's pancreas does not produce enough insulin

Diabetes Mellitus Type II

Glucose isn't properly processed due to insulin insensitivity


Excess hair growth


Osteoporosis, osteomalacia, kidney stones


Spasms, tetany, seizures


Menstrual cramps severe enough to prevent participation in normal activities

Multiple Endocrine Neoplasia

Predispose people to develop benign tumors of the endocrine glands


Bone loss and weakness

Polycystic Ovary Syndrome

If untreated may lead to infertility, excessive hair growth, acne, obesity, diabetes, heart disease, high blood pressure, abnormal bleeding from the uterus, and cancer.


Caused by lack of iodine in diet

Graves' Disease

Autoantibody 'thyroid-stimulating immunoglobulin' (TSI) mimics the action of TSH on the thyroid

Hashimoto's Thyroiditis

Autoimmune attack on thyroid causes it to become swollen and unable to synthesize sufficient hormone


Any condition in which the thyroid is overactive


Any condition in which the thyroid is underactive


Thyroid deficiency in newborns can lead to growth failure and permanent mental retardation

Low T3 Syndrome (Wilson's Syndrome)

Reduced thyroid function due to a failure to convert sufficient T4 to T3
