Bloating – stomach distension due to gas built in the stomach or bowel – may be caused by certain foods, intestinal disorders, bacterial overgrowth or food poisoning with bacteria or parasites.
What Causes Bloating Shortly After Eating?
Bloating in the upper abdomen appearing within minutes after starting a meal may be caused by:
- Carbonated drinks, like soda or beer
- Baking soda
- Helycobacter pylori infection of the stomach. Infection with this bacterium is common and may cause nausea, early satiety, bloating and burping shortly after starting a meal

- Fibrous tissue (resulting from chronic infection, ulcer or surgery) obstructing the exit of the stomach (pylorus)
- Hypothyroidism
- Atherosclerosis of abdominal vessels or damage of abdominal nerves in long lasting diabetes, or smoking
