Hard lumps in the stomach may be caused by pyloric obstruction, gastric redundancy and cirrhosis of the liver. 1. Pyloric obstruction: the pyloric stenosis may be caused by mucosal edema or contraction of the pyloric annulus muscle caused by ulcers, etc. When a large amount of food accumulates in the stomach, hard lumps will appear in the stomach because the gastric mucous membrane absorbs the water of the food. 2. Gastric superfluous organisms: if the patient suffers from gastric stones, gastric polyps, gastric tumors and other diseases, when the foreign body grows to a certain extent, pressing the stomach may feel the phenomenon of hard lumps in the stomach. 3. Cirrhosis of the liver: If the liver cells are damaged and sclerosis occurs, and the location of the lesion is in the left quarter of the ribs, it may cause the illusion of hard lumps in the stomach. Therefore, if there are hard lumps in the stomach, the patient should go to the hospital in time, to clarify the cause of the disease, and target treatment.
