Dr. Álvaro Campillo warns poor posture during meals affects gut health

Surgeon and microbiome specialist Dr. Álvaro Campillo has warned that body posture during meals can significantly impact digestive health, food transit, and the gut microbiome.

According to Campillo, slouching while eating—particularly with crossed legs—creates pressure on the torso that can impede breathing and digestion. This poor posture is linked to slower intestinal transit, increased gas accumulation, and reduced oxygen supply to the digestive tract. He notes that such habits may increase the risk of reflux, heartburn, bloating, constipation, and microbial imbalance.

To optimize digestion, Campillo recommends sitting upright with a straight back and relaxed shoulders, ensuring both feet remain flat on the floor. He cites research suggesting that gas accumulation can be ten times lower when sitting upright compared to slouching.
