In the language of medicine, there is no disease called gastric. The organ which is referred to as gastric is known as stomach in Bengal. Although there is no disease called gastric, the problems that patients come with are also diseases. None of this is just gas. Again, any acidity. Gas: According to the American Research Center for Gastroenterology, one -fourth of the world's population suffers from gas. Remember , it is normal for gas to build up in the intestines (small intestine and large intestine) after a meal. At least one to four points of gas is produced in the intestine in 24 hours. This gas is usually swallowed 14 times in 24 hours or is excreted in the anus. The food we eat is digested. This process of digestion produces gas as a byproduct. In the large intestine (where digested food is stored as feces) there are many bacteria. These also play a special role in gas production. The gases produced in the gut include carbon dioxide , hydrogen and methane. Sometimes sulfide gas is also produced. If gas is produced more than usual for some reason, gas problem is created. There are generally three types of gas production problems. Belching or bloating, blistering or bloating, fasting, or gas in the anus. This acid has a slippery lining on the inside of the stomach so that it does not digest or erode the lining of the stomach. This coating contains mucus layer or lining of mucus. If for some reason the acid secretion is increased or the gastric mucosa is eroded (ulcer), the surface of the stomach burns. The stomach is attached to the upper esophagus (part of the esophagus). If for some reason this acid gets into the esophagus , the heartburn problem occurs. Heartburn is also known as heartburn. Helicobacter pylori is a major cause of gastrointestinal erosion in 90% of people with acidosis in Bangladesh. This inflammation is usually more on an empty stomach. With this the mouth becomes sour , sometimes there is also nausea. People with ulcers may have hemorrhage and black stools
