There are many reasons for the hidden pain in the left upper abdomen under the ribs, and the common ones are diseases of the digestive system, circulatory system and respiratory system.
1. Digestive system: Stomach disorders such as chronic gastritis, gastric ulcers and even stomach tumors may cause subcostal pain in the upper left abdomen. In addition, the left side of the colon lesions, such as colitis, colon polyps, etc. can also appear in the left side of the subcostal pain.
2. Circulatory system: such as myocarditis, coronary heart disease, etc., can cause the left side of the subcostal pain. At the same time, patients may also be accompanied by chest tightness, shortness of breath and other symptoms.
3. Respiratory system: usually the left upper abdomen subcostal pain is seen in its surrounding lung inflammation such as bacterial pneumonia.
If the pain is intermittent for a long time, the patient should consult the doctor as soon as possible for diagnosis and symptomatic treatment.
