Hormone secretion abnormality: patients mostly have acromegaly or gigantism, while increased secretion of ACTH (adrenocorticotropic hormone) will lead to Cushing’s syndrome, which is mainly manifested as full-moon face, buffalo back and so on, and lack of hormone level will lead to hypokalemia, low blood pressure, electrolyte disorders and other symptoms. 2. Pituitary tumor: when the tumor is too big and presses the nerves, headache will occur, and when the optic nerve is pressed, blurred vision will occur. 3. Abnormal secretion of prolactin: manifested as menstrual disorder, menopause, lactation, or sexual dysfunction and infertility. After the patients have the above symptoms, they should seek early medical examination to confirm the diagnosis, and then treat with different types of lesions.
