In early pregnancy, diarrhea may be caused by improper diet or cold. The problem can be solved by improving the diet and keeping warm. If the diarrhea is severe, it can cause contractions, which can lead to miscarriage. More attention needs to be paid in the early stages of pregnancy. After finding the problem, you can ask your doctor in time to prevent the unfortunate occurrence. When it comes to the diet of pregnant women, it is best to be light and not to eat anything too greasy to increase the burden on the stomach and intestines. Try to avoid eating raw and cold food, and do not eat spicy and stimulating food. Pregnant women can drink more millet porridge and warm liquid food to relieve the symptoms of diarrhea.
