The cause of pituitary tumors in women is not fully understood and may be related to genetic mutations and disorders of the hypothalamus regulating hormones. Most pituitary tumors are benign, but the cause of the disease is not clear. In some women, pituitary tumors are thought to be related to genetic abnormalities in the cells and disorders of hypothalamic hormone regulation, while simple disorders of hypothalamic hormone regulation do not cause pituitary tumors. In addition, for a small percentage of people with a family history of pituitary tumors, there may be an increased chance of developing the disease. Pituitary tumor can cause headache, vision loss, visual field defect, nausea and vomiting, excessive sweating, insomnia and other symptoms, which will easily affect the quality of life and health. Therefore, pituitary tumor patients need to actively cooperate with doctors to prevent complications such as vision loss, permanent hormone deficiency and pituitary stroke. It is recommended that people diagnosed with pituitary tumors actively cooperate with their doctors and have regular medical checkups. People with vision loss and visual field defects need to be accompanied by their family members to avoid accidents such as collision and fall.
