The pressure on the stomach and intestines is relatively low when a pregnant woman is lying down, so the reaction to pregnancy vomiting will be relatively light. But this situation varies from person to person, not everyone lying down will reduce the reaction of pregnancy vomiting. During pregnancy, due to the rise of human chorionic gonadotropin in the body, gastrointestinal peristalsis slows down, gastric juice secretion decreases, 90% of pregnant women will experience stomach bloating, nausea, vomiting, heartburn, acid reflux and other gastrointestinal symptoms. Usually it will gradually improve after 4 months, so don’t worry too much. Pregnant women are advised to eat light food and avoid oily and spicy food when they have vomiting. Keep a happy mood, pay attention to emotional stability, regular work and rest, eat more fresh vegetables and fruits, and replenish water in time to avoid dehydration. Try not to go to places with irritating odors or go there as little as possible, and open windows regularly in the living environment to keep the air circulating. If the pregnancy vomiting is particularly serious and you can’t eat anything, consider severe pregnancy vomiting, which requires medical treatment.
