Stomach Conditions
|
- Zollinger-Ellison syndrome (ZES): One or more tumors that secrete hormones that lead to increased acid production. Severe GERD and peptic ulcer disease result from this rare disorder.
- Gastric varices: In people with severe liver disease, veins in the stomach may swell and bulge under increased pressure. Called varices, these veins are at high risk for bleeding, although less so than esophageal varices are.
- Stomach Bleeding: Gastritis, ulcers, or gastric cancers may bleed. Seeing blood or black material in vomit or stool is usually a medical emergency.
- Gastroparesis: Nerve damage from diabetes or other conditions may impair the stomach’s muscle contractions. Nausea and vomiting are the usual symptoms.
