12 Causes of Stomach Pain


7. Gluten intolerance

Gluten is protein present in wheat, barley and rye that causes a reaction in individuals who are gluten intolerant. The most severe form of this condition is known as celiac disease where the body is unable to process gluten at all. Common symptoms include digestive discomfort, abdominal pain and cramping, gas, bloating and a sense of fatigue.

Upon ingestion, gluten causes damage to the small intestine, impairing its ability to absorb nutrients properly. This malabsorption can then cause chronic diarrhea, weight loss and even malnutrition.

8. Gallstones

Gallstones are hardened deposits of cholesterol, calcium salts or bilirubin in the gallbladder. While the majority of people may not experience gallstone symptoms, others can complain of abdominal discomfort including frequent pain, fever, and nausea or vomiting along with indigestion and discolored urine or stools.

Stomach pain in this case is experienced when the stones block the flow of bile in the gallbladder and an increased pressure develops in the organ. If left untreated, the pressure can lead to gallbladder rupture.

9. Peptic ulcers

Painful sores that develop in the stomach lining, lower esophagus or the small intestine are known as peptic ulcers. Typically these can be identified by a burning abdominal pain that can span between the navel and the chest area. The pain may range from mild to severe and may even be uncomfortable enough to wake individuals up at night.

Sores develop as a result of inflammation caused by the H. pylori bacteria or from erosion of stomach acids. Peptic ulcers may be detected when changes in appetite are noticed or other symptoms like nausea, unexplained weight loss, indigestion, vomiting and dark stools are observed.
