Introduction
Dizziness and nausea during sleep may be caused by conditions such as cerebral infarction, excessive fatigue, or hypertension. When cerebral infarction occurs in the posterior circulation region, it can damage the cerebellar-vestibular nervous system, leading to symptoms like dizziness and vomiting. After intense physical labor, dizziness and nausea may arise due to hypoglycemia or insufficient cerebral blood supply. A sudden increase in blood pressure beyond the threshold of cerebral perfusion can also cause these symptoms.
Dizziness and nausea during sleep are usually caused by conditions such as cerebral infarction, excessive fatigue, or hypertension.
1. Cerebral infarction: If cerebral infarction occurs in the posterior circulation area, it may damage the cerebellar-vestibular nervous system, leading to symptoms such as dizziness and vomiting. It is recommended to seek timely medical attention at a hospital and follow medical advice to take medications such as butylphthalide soft capsules and betahistine mesylate tablets.
2. Excessive fatigue: After intense physical activity, symptoms such as nausea, dizziness, and vomiting may occur due to low blood sugar, insufficient cerebral blood supply, or decreased cardiopulmonary function. These symptoms can be improved by consuming appropriate amounts of carbohydrates, getting adequate rest, and enhancing physical exercise.
3. Hypertension: A sudden increase in blood pressure beyond the brain's cerebral perfusion threshold may lead to symptoms such as nausea and vomiting. It is recommended to follow medical guidance and take antihypertensive medications such as captopril tablets or irbesartan tablets to manage the condition.
