Do not want to eat, stomach discomfort need to be alert to diseases such as gastritis and indigestion, some of them are related to gastric ulcer, gastric cancer and other diseases.

Secondly, when indigestion occurs, the stomach cannot empty the food in time, which leads to an increased burden. The food in the stomach will not only cause irritation to the stomach wall, but will also produce too much gas due to abnormal fermentation, and the patient will therefore suffer from loss of appetite, accompanied by a feeling of stomach distension. Then gastric ulcer will cause stomach acid to irritate the stomach lining during the attack, thus affecting the stomach discomfort, which will also affect the appetite in the long run and lead to loss of appetite. Finally, gastric cancer is a malignant tumor, especially in the advanced stage, patients will suffer from loss of appetite and stomach discomfort because the gastric power is affected.
