Back pain caused by stomach pain can be the result of gastric ulcers, reflux esophagitis, and so on. The anatomical location of the stomach and the back is relatively close to each other. When the pain in the stomach is particularly severe, the pain will be radiating to the surrounding area, which will be accompanied by back pain. 1. The pain caused by gastric ulcer is more intense in nature, and in some patients, the ulcer surface is located in the back wall of the stomach body. When gastric acid infringes on the ulcer surface, the smooth muscle of the back wall will spasm and contract, thus causing pain in both the stomach and the back. 2. Reflux esophagitis: there can be obvious heartburn, acid reflux, stomach pain, which can be reflected to the back. Gastroparesis patients who experience radiating pain in the back should seek medical attention as soon as possible to clarify the cause of the disease under the guidance of a specialized physician, and actively treat the disease to avoid delaying the condition.
