Garlic is useful for preventing the development of gastric disease, but does not treat it. Garlic contains a large amount of allicin, which has been shown in studies to be able to resist Helicobacter pylori, reduce nitrite levels in the stomach, and have some antibacterial and anti-inflammatory effects. However, gastric disease is a general term that usually includes chronic gastritis, gastric ulcer, duodenal ulcer, gastric cancer and other stomach disorders, each of which has a different treatment plan. After the occurrence of gastric diseases, you should seek medical attention to improve the gastroscopy and blood tests, and make a clear diagnosis according to the test results, and carry out scientific and standardized treatment under the guidance of doctors to promote the recovery of the disease. In addition, you should develop good eating habits in daily life, chew slowly, eat less and more often, avoid overeating, reduce the intake of cold, greasy and spicy stimulating foods, drink less or no strong tea, coffee and other stimulating drinks, and quit smoking and alcohol. In addition, garlic is a spicy and stimulating food, so too much of it may stimulate the gastric mucosa and lead to excessive secretion of gastric acid, which may cause acid reflux, heartburn, abdominal distension, abdominal pain and other symptoms, and may lead to further aggravation of the patient’s condition.
