In 38 weeks of pregnancy, as the fetus increases in size, part of the nutrition is supplied to the fetus, it is easy to have low blood pressure and low blood sugar, and because of the heavy body burden of pregnant women, it is easy to cause insufficient cerebral blood supply and cervical compression, and these conditions can induce dizziness. If combined with other diseases, it may also lead to dizziness in pregnant women at 38 weeks: 1. Hypoglycemia: If in 38 weeks of pregnancy, pregnant women eat too little resulting in hypoglycemia, episodes of dizziness can occur, accompanied by palpitations, weakness, cold sweat symptoms. Such pregnant women should pay attention to a reasonable diet, and it is best to take some cookies or candies when going out to eat when the symptoms of dizziness appear, which can help relieve the symptoms; 2, hypotension: if the blood pressure drops at 38 weeks of pregnancy, the blood flow to the brain will be reduced, and then the symptoms of dizziness can appear. It is recommended that pregnant women should strengthen nutrition and take blood pressure-raising drugs under the guidance of a doctor if necessary; 3. Insufficient cerebral blood supply: due to the excessive size of the fetus at 38 weeks of pregnancy, it compresses the abdominal blood vessels, resulting in a sharp decrease in the effective circulation of blood, which in turn causes cerebral ischemia and hypoxia, causing dizziness. It is recommended that pregnant women take the left side position when sleeping to reduce the compression and relieve the discomfort symptoms; 4. Cervical spine compression: at 38 weeks of pregnancy, some pregnant women may have excessive weight growth, resulting in the compression of blood vessels in the neck, thus causing the symptoms of dizziness. However, the dizziness symptom can be effectively relieved by changing the body position. In this case, pregnant women should pay attention to avoid maintaining a posture for a long time, and try to avoid abnormal compression of the cervical spine; 5, combined diseases: if pregnant women themselves suffer from cardiovascular disease or anemia, symptoms of dizziness can occur. In this case, you should go to the hospital in time to clarify the cause and treat the cause.
