Pregnancy vomiting is a normal early pregnancy reaction in early pregnancy. Due to the different tolerance of different individuals and the different hormone levels in the body, there will be a situation where some people experience pregnancy vomiting while others do not. In early pregnancy, due to the large changes in hormone levels in the body, it will lead to gastrointestinal reactions such as nausea and vomiting. However, different individuals have different tolerance to early pregnancy reactions, and the degree of change in hormone levels in the body is also different, so there will be individual differences in the symptoms of pregnancy vomiting and the severity of the reaction. If the pregnant woman’s physical condition is poor or she suffers from intestinal diseases, the symptoms of pregnancy vomiting may be serious, while the pregnant woman’s tolerance is better, the degree of pregnancy vomiting reaction may be lighter, or even no pregnancy vomiting. If a pregnant woman has severe symptoms of vomiting, dehydration or other symptoms, it is recommended that she go to the hospital in a timely manner.
