I get sick after dinner. What's going on?

Nausea after a meal may be caused by eating too much, eating too much spicy, raw and cold stimulating food; it may also be caused by chronic gastritis, gastric ulcer, reflux esophagitis; or hepatitis, cholecystitis and other diseases. You need to go to the hospital digestive department to do abdominal B ultrasound examination to confirm the cause.
