Patients with cerebral blood supply insufficiency can get pregnant. First of all, the pathogenesis of cerebral blood supply insufficiency is due to the occurrence and development of atherosclerosis with the increase of age, which leads to the thickening of blood vessel wall and the narrowing of blood vessel lumen, so that the flow of cerebral blood per unit of time through the brain decreases and the cerebral blood supply insufficiency occurs. Normal cerebral blood flow per minute is 800-1000ml, below this value is called the phenomenon of cerebral ischemia. It does not affect pregnancy because cerebral hypoperfusion can be treated with medications that improve blood circulation and will soon improve. In addition, patients with cerebral blood supply insufficiency should avoid too much mental stress, avoid overwork, and should not stay up late at night, drink alcohol, smoke, eat spicy and stimulating food, eat a low-salt, low-fat diet, and should not eat fatty and greasy food, because all of the above reasons will lead to the aggravation of cerebral blood supply insufficiency, which will cause the patient’s pregnancy to be affected.
