What Are The Symptoms Of A Pituitary Tumor?

Weight Loss Or Gain

A common symptom of a pituitary tumor is sudden weight loss or gain. Several different types of pituitary tumors can cause unexplained weight loss or weight gain. Adenoma tumors that secrete too much ACTH hormone can cause a patient to gain weight in their belly, chest, and face. Pituitary tumors referred to as thyroid-stimulating hormone-secreting adenomas cause increased production of thyroid-stimulating hormone, which produces a state of an overactive thyroid gland. A common symptom that occurs in patients who have high thyroid-stimulating hormone levels is unexplained weight loss. Tumors of the pituitary gland referred to as macroadenomas can cause damage to parts of an individual's pituitary gland that results in a shortage of one or more pituitary hormones in the body. Low levels of these hormones can result in either unexplained weight loss or unexplained weight gain, depending on which hormone or hormones are being affected.
