Signs of pressure from a tumor in the pituitary gland include headache, loss of body hair, amenorrhea or infrequent menstrual periods, increased urination and weakness, says Mayo Clinic. Additional symptoms include nausea, vomiting and loss of peripheral vision.
Pituitary gland tumors sometimes produce hormones, and these hormones can stimulate other glands to produce hormones of their own, explains Mayo Clinic. An adrenocorticotropic hormone-secreting tumor causes the adrenal glands to make too much cortisol. The symptoms of this are bruising, stretch marks, thinning skin, hypertension, hyperglycemia and a hump on the back caused by the accumulation of fat.
If the tumor causes the body to produce too much growth hormone, the symptoms include joint pain, crooked teeth, hirsutism, large feet and hands, and problems with the heart, reports Mayo Clinic. Children and adolescents may grow unusually tall.
Diabetes inspidus is another problem that is caused by a damaged pituitary gland, says MedlinePlus. This condition occurs when the pituitary gland does not produce enough antidiuretic hormone. The symptoms include the patient passing great amounts of dilute urine throughout the day and suffering from unquenchable thirst.
Hypopituitarism causes a great number of symptoms because of the number of hormones the pituitary controls, notes MedlinePlus. Symptoms can range from short height if a child suffers from the condition to infertility, weight loss, low blood sugar and low blood pressure.
