The occurrence of diarrhea is usually not related to pregnancy. Most of the diarrhea is caused by unhygienic diet, gastrointestinal infection, and gastroenteritis. Diarrhea can be caused if the patient eats something unclean or gets cold, etc. Pregnancy is usually considered only if there is a delay in menstruation. Since the first symptom of pregnancy is menopause, if a woman with diarrhea symptoms also has menopause and nausea, it is recommended to go to the hospital for a test, mainly a blood test for chorionic gonadotropin. If the test result is significantly higher than the normal range, it indicates pregnancy, because the chorionic gonadotropin level in the body will increase significantly after pregnancy.
