K20-K31: Diseases of oesophagus, stomach and duodenum
K29: Gastritis and duodenitis
Gastritis and duodenitis are conditions that cause inflammation in the lining of the stomach and the start of the small intestine, respectively. Commonly brought on by infections, long-term use of pain relievers, or heavy alcohol intake, they can also result from issues like stress and certain autoimmune disorders. Symptoms may include upper abdominal pain, nausea, and, in more severe cases, vomiting blood or having black, tarry stools. Symptoms often worsen when the stomach is empty. Over time, the inflammation can damage the gastrointestinal lining, leading to complications such as stomach ulcers or, in rarer cases, stomach cancer. Both conditions mainly affect the digestive system and can cause discomfort and disruption to one's daily life.
