Yes it is true. Even stomach disorders can be linked to gallstones.
Gallstones will cause digestive problems, which can lead to regurgitation of bile acids and bile salts into the stomach. This changes the composition and amount of mucus created in the stomach. The mucous protects the surface lining of the stomach from the hydrochloric acid. When the protective layer is compromised a condition develops called gastritis.
You can have a chronic or acute form of gastritis. When the surface cells are exposed to acid gastric juice, the cells absorb hydrogen ions. When this happens the acidity is increased and it can cause an inflammatory reaction. In more serious cases there could be an ulcer, peptic or gastric. Duodenal ulcers will develop when acid leaving the stomach
In more severe cases there may be ulceration of the mucosa (peptic or gastric ulcer), bleeding, perforation of the stomach wall and peritonitis, a condition that occurs when an ulcer erodes through the full thickness of the stomach or duodenum and their contents enter the peritoneal cavity. Duodenal ulcers develop when acid leaving the stomach wears away the duodenum's lining. Usually this will accompany high acid production known as Esophageal reflux (heartburn) where the stomach acid washes back into the esophagus and creates irritation of the tissues lining in the esophagus.
Overeating, cigarette smoking, eating a lot of animal protein and fats, excessive alcohol consumption, daily coffee drinking, x-radiation, aspirin, inflammatory drugs, dehydration, stress, etc., are also causes of heartburn and gastritis.
A good many doctors now think that a "bug" causes stomach ulcers and they are fighting it with a combination of antibiotic drugs. This brings some relief but if there is not a life style change it will be back. Also, even though they are having a high recovery rate it is often found to have side effects and it comes back after you discontinue the antibiotic.
If the stomach, its lining, and the cells are healthy this bug would not be able to compromise the stomach. The infection is only possible due to the already damaged cell tissue in the stomach.
It is the gallstones in the liver and gallbladder that keep a regular back flushing of bile into the stomach, which causes damage to an increasing number of stomach cells. Antibiotics are not necessarily the answer because they destroy the natural stomach flora, including the good bacteria that normally help break down damaged cells. So although the antibiotic approach results in a quick relief of symptoms, it also lowers stomach performance permanently, which sets up the body for more severe challenges than just dealing with an ulcer. Looking for the fast and easy way usually does not work out as planned. On the other hand, most stomach disorders disappear spontaneously when all existing gallstones are removed, and a healthy diet and balanced lifestyle are regularly maintained.
