K31: Other diseases of stomach and duodenum

The diseases classified under the category 'Other diseases of stomach and duodenum' are a set of disorders that primarily affect the stomach and the duodenum, the first part of the small intestine. These conditions may be caused by multiple factors such as certain bacteria, chronic gastritis, autoimmune conditions, stress, certain medications, and lifestyle habits like alcohol consumption or smoking. Common symptoms of these diseases include stomach pain, nausea, vomiting, bloating, discomfort in the upper abdomen, and in some severe cases, unexplained weight loss. Over time, the symptoms might exacerbate leading to more serious complications if not addressed. Depending on the specific disease, these conditions can affect digestion, nutrient absorption, and can even influence the overall functioning of the gastrointestinal system. It is crucial to recognize that while these diseases present commonly in the digestive system, they can indirectly impact other systems of the body as well.
