Does bad stomach cause back pain?

Stomach problems may cause back pain.

When suffering from some serious stomach diseases such as gastric ulcer, duodenal ulcer, etc., especially the ulcer of the back wall, it may cause radiation pain in the back. This is because there is a certain connection between the nerve in the affected area and the nerve in the back. When the stomach disease stimulates the relevant nerve, the pain may radiate to the back. In addition, in patients with acid reflux disease, acid reflux stimulates the esophagus, causing heartburn, chest pain and other symptoms. Sometimes the pain may also radiate to the back. In this case, stomach acid stimulation is one of the main causes of back pain. Not only that, but severe inflammation of the stomach, if spread to surrounding tissues, may affect tissues and nerves in the back, causing back pain.
