Pain in the lower part of the chest, mainly under the glabella, is commonly associated with diseases such as gastritis or gastric ulcer. The pain may be obvious after eating and may be accompanied by bloating, nausea, and vomiting, with recurrent episodes and a significant loss of appetite. Prolonged ulcer disease can lead to anemia and, in severe cases, complications such as bleeding and perforation caused by the ulcer. Gastroscopy can clearly diagnose and reveal superficial ulcer formation in the stomach wall, and in severe cases, also combined with erosion. Usually, you should pay attention to the structure of your diet with light, easily digestible food. Oral proton pump inhibitors can be taken to protect the mucosa of the gastrointestinal tract, and regular gastroscopy reviews should be performed. In severe cases, surgery can be chosen to remove the ulcerated surface, and regular review should also be performed after the surgery.
