Dizziness, panic, nausea and vomiting may be related to otolithiasis, insufficient blood supply to the brain and anemia. 1. Otolithiasis: Otolithiasis is a peripheral vertigo disease associated with changes in head movement. Strong vertigo or dizziness will occur when the position of the head changes, and it will be accompanied by symptoms of autonomic dysfunction such as nausea and vomiting. 2. Insufficient cerebral blood supply: it may be caused by one’s own hypertension or other cardiovascular and cerebrovascular diseases, resulting in insufficient blood supply to the brain. Insufficient blood supply to the brain is caused by the circulatory disorder of cerebral arteries, which leads to insufficient blood supply to the brain. Insufficient blood supply to the brain will lead to headache, dizziness, nausea, vomiting, fluctuation of blood pressure and other symptoms. 3. Anemia: Anemia is the absence of a sufficient amount of red blood cells in the peripheral blood of the human body. The common symptoms of anemia are dizziness, weakness, easy fatigue, panic, etc. If anemia is more serious, it may lead to anemia in the digestive tract as well, which in turn causes nausea and vomiting. 4. Heart disease: heart disease can not be ruled out as a cause of dizziness, panic, nausea and vomiting, because heart disease patients have poor cardiac function or cardiac arrhythmia, it will cause insufficient blood supply to the cerebral arteries, thus inducing discomfort. It is not recommended that patients treat themselves, because the causes are different, the specific treatment will be different, and it is recommended that patients go to the hospital in a timely manner.
