Gastritis is a condition affecting which part of the body?

Gastritis specifically refers to the inflammation of the stomach lining. This condition can occur due to various factors, including excessive alcohol consumption, chronic stress, certain medications, and bacterial infections such as H. pylori. When the stomach lining becomes inflamed, it can lead to symptoms such as abdominal pain, nausea, vomiting, and indigestion. Understanding that gastritis affects the stomach lining helps in recognizing its symptoms and potential treatments, such as antacids or other medications aimed at reducing stomach acidity and promoting healing. The other body parts listed—intestines, liver, and kidneys—do not relate directly to the condition described, making the connection to the stomach lining essential in defining gastritis.
