Regurgitation after meals may be caused by pregnancy, stomach disorders, liver and gallbladder diseases. 1. Pregnancy: When married women experience regurgitation after meals with symptoms such as delayed menstruation, it may be an early pregnancy reaction caused by elevated chorionic gonadotropin due to pregnancy. 2. Stomach diseases: indigestion, gastritis, gastric ulcer, gastric cancer and other stomach diseases may affect the digestion and peristaltic function of the stomach and cause regurgitation after meals. 3. Liver and gallbladder diseases: Viral hepatitis, alcoholic hepatitis, fatty liver, liver cirrhosis, liver cancer, cholecystitis and other liver and gallbladder diseases may lead to abnormal secretion or excretion of digestive enzymes and regurgitation after meals. Reflux after meals may also be caused by other reasons, so you need to go to the hospital for further examination of chorionic gonadotropin, gastroscopy, liver function, abdominal ultrasound and other items to find the cause.
