There is a hard lump in the fossa of the heart stomach flatulence may be caused by physiological factors, or may be caused by gastric smooth muscle tumor, gastric cancer and other disease factors, the former caused by no special treatment, the latter caused by the need for targeted treatment under the guidance of the doctor, such as general treatment, drug treatment, surgical treatment and so on. 1. Physiological factors: the heart socket is usually located in the middle depression under the sternal raphe, and it can be mistaken as a hard lump when the raphe is bent to the abdomen for a long time. If a large amount of gas-producing and indigestible food is eaten at one time at the same time, it will cause abdominal distension, which can be caused by the use of pro-digestive drugs, such as digestive enzyme tablets. 2. Gastric smooth muscle tumor: for single, diameter less than 2 cm of the tumor can be endoscopically resected, non-tibial, diameter greater than 2 cm or accompanied by obstruction, bleeding and other symptoms, laparoscopic or open surgical resection is recommended. 3. Gastric cancer: there is a possibility that there is a malignant tumor in the stomach, such as cardia cancer or gastric sinus cancer, when the mass grows up, it can be touched in the upper abdomen, and it is usually accompanied by upper abdominal symptoms, such as abdominal pain, bloating, acid reflux, burping, and even black stools, if necessary, it is necessary to carry out gastroscopy for further clarification, and if diagnosed as gastric cancer, it is necessary to carry out radical surgery for gastric cancer. If the diagnosis is gastric cancer, radical gastric cancer surgery is needed. After eliminating physiological factors, it is recommended to go to the hospital for consultation, clear diagnosis and symptomatic treatment.
