What causes pituitary tumors?

As the incidence of pituitary tumors gradually increases, people begin to pay attention to this tumor disease. I wonder how much do you know about pituitary tumors? To further understand pituitary tumors, let's first talk about what causes pituitary tumors?

1. The endocrine manifestations of different types of pituitary adenomas are the key to the causes of pituitary tumors:

(1) Growth hormone cell adenoma: The early tumor is only a few millimeters in size. The main cause of pituitary tumors is excessive secretion of growth hormone. Minor patients may grow too fast and even develop into giants. After adulthood, they will show acromegaly. Such as facial changes, enlarged forehead, protruding lower jaw, large nose and thick lips, thick fingers, tight shoes and hats, several changes to larger sizes, and even have to be specially made. Some patients also have increased appetite, rough hair and skin, pigmentation, numbness of fingers, etc.

(2) Prolactin cell adenoma: The main causes of pituitary tumors are amenorrhea, galactorrhea, and infertility. In severe cases, the symptoms include loss of armpit hair, pale and delicate skin, increased subcutaneous fat, fatigue, easy fatigue, lethargy, headache, and sexual dysfunction. In men, the symptoms include decreased libido, impotence, breast hyperplasia, sparse beards, and in severe cases, atrophy of reproductive organs, decreased sperm count, and infertility. There are not many cases of male to female changes.

(3) ACTH cell adenoma: Clinical manifestations include centripetal obesity, moon face, buffalo hump, sanguineous constitution, purple lines on the skin of the abdomen and thighs, and increased vellus hair. In severe cases, patients may suffer from amenorrhea, loss of libido, general fatigue, and even bedriddenness. Some patients also have hypertension and diabetes.

2. Visual field impairment is also one of the causes of pituitary tumors:

Early pituitary adenomas often do not cause visual disturbances. If the tumor grows and extends upward, compressing the optic chiasm, visual field defects will occur. The upper outer quadrant will be affected first, and the red field of vision will be manifested first. Later, as the lesion grows larger and the compression becomes more severe, the white field of vision will also be affected, and the defect can gradually expand to bilateral temporal hemianopsia.

Through the above introduction, we understand the causes of pituitary tumors. Therefore, we must pay attention to it and do a good job of prevention in daily life. If symptoms related to pituitary tumors occur, we should seek medical attention in time.
