The causes of fast heart rate and nausea may be hypoglycemia, food poisoning, hypertension and cardiac arrhythmia.
1. Hypoglycemia: When hypoglycemia strikes, the glucose level in the plasma is lower than the normal physiological level, and clinical manifestations such as dizziness, nausea and rapid heart rate will occur.
2. Food poisoning: When food poisoning is caused by consuming unclean or toxin-containing food, the toxin will stimulate the gastrointestinal tract, causing nausea, vomiting, abdominal pain, diarrhea and other symptoms, and when the symptoms are more serious, it can lead to autonomic nervous system being affected, such as elevated blood pressure, increased heart rate and so on.
3. Hypertension: If you have high blood pressure, it can cause a reflexive increase in the level of catecholamines in the body, and catecholamines will stimulate the heart to contract, so it will lead to a fast heart rate. High blood pressure for a long time will increase the cerebrovascular pulse pressure, causing headaches, dizziness and other symptoms, and in severe cases, nausea.
4. Arrhythmia: heart disease, including myocarditis, coronary heart disease and rheumatic heart disease, including heart pumping malfunction of the phenomenon can lead to arrhythmia. When arrhythmia affects gastrointestinal function, it can cause nausea.
If you have a fast heart rate and nausea, you should go to the hospital to find out the cause and actively cooperate with your medical professional.
