Why Do I Bloat After Eating

If after every meal you feel your belly inflating like a balloon, you're not alone. Postprandial abdominal bloating affects more than 30% of the adult population. The most common cause isn't what you eat—it's who lives in your gut.

What Happens Inside Your Gut

When you eat, your gut microbiome ferments undigested carbohydrates, producing gases. If you have dysbiosis (an imbalance in your gut microbiome), this fermentation spirals out of control, resulting in the bloating that bothers you.

Most Common Causes of Post-Meal Bloating

  • Gut dysbiosis: excess gas-producing bacteria
  • SIBO: bacterial overgrowth in the small intestine
  • Lactose/gluten intolerance: influenced by your microbiome
  • Low microbial diversity: reduced nutrient metabolism
  • Chronic stress: cortisol alters microbiome and slows digestion
