Most people have pregnancy reactions after pregnancy, which will gradually reduce and disappear in the first 3 months of pregnancy, but everyone’s constitution is different, and some people have pregnancy reactions throughout pregnancy, and they are more serious. Due to the secretion of human chorionic gonadotropin by placental trophoblast cells after pregnancy, human chorionic gonadotropin hormone stimulates the gastrointestinal tract and causes nausea and vomiting. When the pregnancy is 8-10 weeks old, human chorionic gonadotropin reaches a peak, and after another 2 weeks or so, this hormone will gradually decline and reach a stable trend, so the early pregnancy reaction, in most cases, will diminish and disappear in about 3 months. In case of early pregnancy, it is recommended to eat more light and tasty food, and you can also eat some appetizing food to help digestion, and you can take a proper walk to promote the peristaltic movement of gastrointestinal function and ease the early pregnancy reaction. If the early pregnancy reaction is more serious, you need to go to the hospital to give nutritional support such as rehydration and symptomatic treatment to relieve the symptoms.
