  • Gastritis
  • Gastritis is an inflammation, irritation, or erosion of the lining of the stomach. It can occur suddenly (acute) or gradually (chronic). What Causes Gastritis? Gastritis can be caused by irritation due to excessive alcohol use, chronic vomiting, stress, or the use of certain medications such as aspirin or other anti-inflammatory drugs. It may also be caused by any of the following: • Helicobacter pylori (H. pylori): A bacteria that lives in the mucous lining of the stomach; without treatment, the infection can lead to ulcers, and in some people, stomach cancer. • Bile reflux: A backflow of bile into the stomach from the bile tract (that connects to the liver and gallbladder) • Infections caused by bacteria and viruses If gastritis is left untreated, it can lead to a severe loss of blood and may increase the risk of developing stomach cancer.

  • Hyperbilirubinemia
  • Hereditary hyperbilirubinemia refers to the condition where levels of bilirubin are elevated, for reasons that can be attributed to a metabolic disorder.

  • Liver intoxication
  • Stomach cancer
  • Stomach cancer begins when cancer cells form in the inner lining of your stomach. These cells can grow into a tumor. Also called gastric cancer, the disease usually grows slowly over many years. If you know the symptoms it causes, you and your doctor may be able to spot it early, when it’s easiest to treat. What Causes Stomach Cancer? Scientists don’t know exactly what makes cancer cells start growing in the stomach. But they do know a few things that can raise your risk for the disease. One of them is infection with a common bacteria, H. pylori, which causes ulcers. Inflammation in your gut called gastritis, a certain type of long-lasting anemia called pernicious anemia, and growths in your stomach called polyps also can make you more likely to get cancer.

  • Stomach ulcer
  • What is a stomach ulcer? Stomach ulcers, which are also known as gastric ulcers, are painful sores in the stomach lining. Stomach ulcers are a type of peptic ulcer disease. Peptic ulcers are any ulcers that affect both the stomach and small intestines. Stomach ulcers occur when the thick layer of mucus that protects your stomach from digestive juices is reduced. This allows the digestive acids to eat away at the tissues that line the stomach, causing an ulcer. Stomach ulcers may be easily cured, but they can become severe without proper treatment. What causes stomach ulcers? Stomach ulcers are almost always caused by one of the following: • an infection with the bacterium Helicobacter pylori (H. pylori) • long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, or naproxen Rarely, a condition known as Zollinger-Ellison syndrome can cause stomach and intestinal ulcers by increasing the body’s production of acid. This syndrome is suspected to cause less than 1 percent of all peptic ulcers.
