Gastritis is a condition where the stomach lining becomes inflamed, often due to factors such as excessive alcohol use, prolonged medication (NSAIDs), or bacterial infections. Symptoms can range from mild discomfort to severe pain, and treatment usually involves addressing the root cause, such as medication or lifestyle changes.

Mild erythematous refers to slight redness or inflammation, often found during endoscopic exams. In the stomach or intestines, it can indicate irritation or early stages of inflammation caused by infections, acid reflux, or mild gastritis.

Bariatric relates to treatments aimed at weight reduction, especially in individuals with severe obesity. This includes medical, surgical, and behavioral interventions. Bariatric surgery, such as gastric sleeve or bypass, is often a last resort for those who have struggled with losing weight through traditional methods.

A total gastrectomy is a surgical procedure where the entire stomach is removed, usually due to stomach cancer or severe damage. The esophagus is then directly connected to the small intestine. This life-altering surgery requires patients to follow strict dietary guidelines, including smaller, more frequent meals, and take supplements to ensure proper nutrition.
