There are many causes of dizziness in late pregnancy, which may be caused by abnormal blood pressure, hypoglycemia, anemia, neurological disorders and abnormal vestibular function, etc. As this is a special stage near the birth, pregnant women need to pay special attention. I. Common causes and treatment 1. Blood pressure abnormalities: for example, emotional changes in late pregnancy, fear, anxiety, tension, etc., can cause blood pressure fluctuations that lead to dizziness. When blood pressure is too low, it can lead to cerebral ischemia, hypoxia and inadequate supply of local nutrients, so dizziness can occur; when blood pressure is too high, it can lead to a significant increase in cerebral blood perfusion and thus dizziness. In late pregnancy, you should also be especially alert to the possibility of gestational hypertension. If you experience dizziness, it is recommended to monitor your blood pressure dynamically and visit the hospital promptly; 2. Hypoglycemia: sugar metabolism is prone to abnormalities during pregnancy, resulting in dizziness and other symptoms of hypoglycemia. It is recommended to arrange diet rationally and carry candy with you to ingest during dizziness attacks; 3. Anemia: Generally, it is mainly considered to be caused by iron deficiency. As the fetus develops and its own blood volume circulation increases, too much iron is consumed, resulting in insufficient oxygen supply in the blood, which causes dizziness. It is recommended to take more iron supplements during pregnancy, eat iron-rich foods appropriately, such as lean meat, fish, liver, etc., pay attention to proper rest and ensure nutritional supplements to avoid anemia; 4, neurological diseases and vestibular function abnormalities: like ordinary people, pregnant women may themselves have some neurological diseases or vestibular function abnormalities that may lead to dizziness, which can be treated with vestibular nerve inhibitors, such as diphenhydramine, Diazepam, diphenhydramine, etc. Because of the greater restrictions on the use of drugs during pregnancy, drug treatment is required under the professional guidance of a doctor. If dizziness persists without relief during pregnancy, it is recommended to go to the hospital in time to clarify the cause and take targeted treatment. Pregnant women should have regular maternity checkups during pregnancy, and regularly monitor the status of blood pressure and blood sugar; strengthen nutrition, diversify diet, pay attention to rest, ensure sufficient sleep, and relax the mind.
