What Are Stomach Ulcers?

Stomach ulcers, also known as gastric ulcers or peptic ulcers, are open sores that develop on the lining of your stomach or duodenum (the upper part of your small intestine). They can range in size from small spots to larger patches and tend to be extremely tender when touched.

The Science behind Gas due to Stomach Ulcer

Stomach ulcer occurs when there’s damage on mucus lining that protects stomach tissue from harsh acidic digestive fluids (which often breaks down complex substances into simpler molecules). Thus, presence of these open sores could trigger an increased release of acid and gastric residue into stomach.

This increase activates certain enzymes like Protease which carries out digestion process by breaking down protein molecule unto amino-acids thereby releasing gases such as Nitrogen and Sulfur Oxides- causing bloating feeling/belching respectively (interesting huh?)
