Description: Gastritis is the inflammation of the stomach lining, which can cause abdominal pain, nausea, and vomiting. This condition can be acute or chronic, depending on the duration and severity of the symptoms. Acute gastritis occurs suddenly and can be caused by irritants such as alcohol, certain non-steroidal anti-inflammatory drugs (NSAIDs), or bacterial infections, with Helicobacter pylori being the most common. On the other hand, chronic gastritis develops gradually and may be related to factors such as prolonged alcohol consumption, stress, autoimmune diseases, or persistent infections. Typical symptoms include discomfort in the upper abdomen, a feeling of fullness, indigestion, and, in severe cases, gastrointestinal bleeding. Untreated gastritis can lead to more serious complications, such as gastric ulcers or even stomach cancer. Therefore, proper diagnosis and timely treatment are essential, which may include dietary changes, medications to reduce stomach acidity, and, in some cases, antibiotics to eradicate infections. Preventing gastritis involves avoiding known irritants and maintaining a healthy lifestyle.
