Dizziness in early pregnancy is mainly caused by early pregnancy reaction, fatigue, abnormal blood pressure, hypoglycemia, neurological lesions and vestibular system diseases: causes and treatment 1, early pregnancy reaction: early pregnancy due to the increase in the level of progesterone, resulting in intracranial vasodilation, intracranial venous pressure is reduced, thus causing dizziness, this is a normal phenomenon, until after 3 months of pregnancy dizziness will slowly disappear; 2, fatigue: pregnancy After the female body load increases, coupled with poor sleep quality, the sense of fatigue will increase significantly, so there will also be dizziness. It is recommended to work and rest reasonably, do not stay up late and enhance the quality of sleep; 3, abnormal blood pressure: when blood pressure is too low or too high, dizziness will occur. When blood pressure is too low, it will lead to brain ischemia, lack of oxygen and insufficient supply of local nutrients, so dizziness will occur; when blood pressure is too high, it will lead to a significant increase in cerebral blood perfusion, so dizziness will occur. If dizziness occurs in early pregnancy, it is recommended to monitor blood pressure dynamically and go to the hospital in time if there is any abnormality; 4. Hypoglycemia: after pregnancy, metabolism is accelerated and insulin level of pregnant women is high, coupled with pregnancy reactions, such as nausea, vomiting, loss of appetite, etc., which can easily lead to sugar deficiency and thus hypoglycemia, causing dizziness. It is recommended to regulate diet and timely supplementation of nutrient-rich foods, such as rice cakes, corn, etc.; 5. Neurological lesions and vestibular system diseases: for severe dizziness with other symptoms, such as nausea and jet vomiting, you should go to the hospital neurology and otorhinolaryngology to check whether there are neurological lesions and vestibular system diseases, and then carry out targeted treatment. It is recommended to avoid conjugal life in early pregnancy; take folic acid or vitamin supplements under the guidance of a doctor to maintain balanced nutrition; take more rest and relaxation and do not overwork; exercise properly and keep your mood happy.
