Panic and dizziness may be caused by physiological factors, such as lack of sleep, emotional excitement, etc., and may also be a symptom of certain diseases, such as anemia, hypoglycemia, cardiac arrhythmia, cerebral ischemia and so on. 1. Physiological factors: lack of sleep, emotional excitement, etc. can cause abnormal brain function, blood pressure fluctuations, thus showing symptoms of panic and dizziness. Panic and dizziness caused by physiological factors can usually return to normal in a short time. 2. anemia: due to anemia, the hemoglobin content decreases, resulting in insufficient blood and oxygen supply to the brain, and the heart rate is accelerated compensatory, thus showing the symptoms of panic and dizziness. 3. Hypoglycemia: when the patient has hypoglycemia, it will affect the function of brain cells to a certain extent, and make the heart rate accelerate compensatory, so that the symptoms of panic and dizziness appear. 4. Arrhythmia: patients with arrhythmia may suffer from insufficient blood supply to the brain and accelerated heart rate, which may lead to symptoms of panic and dizziness. 5. Cerebral ischemia: Cerebral ischemia can cause sympathetic nerve excitation, which makes patients experience symptoms of panic and dizziness. Panic and dizziness can also be seen in hypertension, coronary heart disease, heart failure, hyperthyroidism, infection, vasovagal reflexes and other diseases, so we can not diagnose the disease based on the symptoms of panic and dizziness, if the patient recurrent symptoms of panic and dizziness, you should go to the hospital in a timely manner to carry out examinations to identify the cause of the disease, standardized treatment under the guidance of a professional doctor, so as to avoid delays in the condition, resulting in adverse consequences.
