Pituitary microadenomas need to be treated because they are intracranial forms of tumors, benign or malignant, that can grow over time, resulting in volume changes and the release of certain abnormal substances. It will have a certain effect on the skull, with an occupying effect, and when it grows to a certain size and stimulates the surrounding nerve tissue, it will form a series of reactions such as headache, dizziness, nausea, vomiting, visual impairment, blurred vision, etc. If the growth belongs to pituitary adenoma with endocrine function, it may secrete corresponding hormones, thus causing endocrine disorders, such as lactation in men or non-lactating women, irregular menstruation in women, which may lead to infertility in the long term, and some people may have thickened terminal knuckles of the limbs and a distinctly different face, which are all changes of endocrine system diseases. Try to actively treat the disease at an early stage, otherwise there is a risk of distal metastasis if it becomes malignant at a later stage, and even erosion of the surrounding bone, so that there is no way of ordinary treatment.
