Weight loss
The stomach ulcers hurt the most when food enters the stomach and signals the body to secrete the gastric juice in the stomach. These gastric juices are a combination of specific enzymes for the digestion of food and hydrochloric acid whose concentration is pretty high. The gastric juice with pretty high acidity again comes in contact with the source already form in the stomach and cause pain. So the people with stomach ulcers should try to avoid meals as much as they can keep the pain at bay. The frequent skipping of the meals leads to weight loss and severe muscle wasting in chronic conditions of stomach ulcers.
