Gastrointestinal infections, blockages, overeating, irritable bowel syndrome, and conditions such as celiac disease and lactose intolerance cause stomach bloating after eating, states Mayo Clinic. Consuming fatty foods, gassy foods or carbonated beverages may lead to stomach bloating.
Individuals who eat too fast or drink through a straw are more likely to suffer from bloating after eating, explains WebMD. Foods that cause bloating include beans, cabbages, broccoli, lettuce and onions. Other conditions that cause bloating include appendicitis, ovarian cysts, urinary tract infections, Crohn's disease and intestinal obstruction, says Healthline. Pregnant women sometimes experience bloating after eating because they digest food slowly.
