It is possible to experience nausea and vomiting half a month after menopause, but it is also important to be alert to the possibility of gastrointestinal disorders. After pregnancy, the body’s human chorionic gonadotropin secretion increases, which will stimulate the stomach and intestines, resulting in nausea, vomiting, as well as loss of appetite, drowsiness and a series of early pregnancy reactions. However, due to the different physique of individuals, the time of early pregnancy reaction is also different. When nausea occurs, if accompanied by obvious abdominal pain, abdominal distension, stool abnormalities should promptly come to the gastroenterology department of the hospital to rule out abnormalities. If the nausea and vomiting are only mild, you need to pay attention to rest, eat a light diet, do not eat stimulating and greasy food, generally after twelve weeks of pregnancy early pregnancy reaction can be relieved on its own. If the symptoms of nausea and vomiting seriously affect your daily life, you need to seek medical treatment, so as not to seriously affect the health of the mother and child.
