Peptic Ulcers
A peptic ulcer occurs in the lining of the stomach or duodenum or just above the stomach in the esophagus (esophageal ulcer). Such ulcers occur as inflammation or soreness within these organs. Ulcers cause severe pain due to the acid that the stomach contains for digestion. They may appear due to long-term use of aspirin or ibuprofen, infection with Helicobacter pylori bacteria, or tumors of the stomach, duodenum, or pancreas.
Gallstones
Gallstones are small and made of cholesterol. Their formation happens in the gallbladder. A person may not be aware of them due to the lack of symptoms, and they also do not need treatment. When a gallstone enters the duct inside the gallbladder, a person may experience severe abdominal pain called biliary colic, lasting from 1 to 5 hours. Gallstones can lead to inflammation of the gallbladder – cholecystitis.
Diarrhea and Constipation
Constipation is a problem with bowel movement when it occurs less than three times a week or is difficult to pass, and it can be caused by a lack of fiber or water in the diet. Diarrhea is a problem with loose or watery stools that may be accompanied by nausea or chills, often caused by infections. In the small and large intestines, coordinated contractions and relaxations of smooth muscles transport food. Diarrhea is associated with water absorption problems, while constipation is associated with the passage or formation of stool.
Dental Caries
Caries occurs as a result of the participation of bacteria in the breakdown of food in the oral cavity. These bacteria produce acids that can damage tooth enamel. The uncontrolled proliferation of bacteria causes the bacteria to digest the sugars left from the food, converting them into acids as waste. These acids then demineralize the enamel of the teeth, create tiny holes, and cause caries.
