Adult Diseases and Conditions: G

  • G6PD Deficiency

    G6PD deficiency is an inherited condition. It is when the body doesn’t have enough of an enzyme called G6PD (glucose-6-phosphate dehydrogenase). This enzyme helps red blood cells work properly. A lack of this enzyme can cause hemolytic anemia. This is when the red blood cells break down faster than they are made.

  • Gallstone Pancreatitis

    Pancreatitis is a disease that causes inflammation and pain in your pancreas, the small organ that produces fluids and enzymes to break down food. This is part of the digestive process. When a gallstone blocking your pancreatic duct causes pancreatitis, it’s known as gallstone pancreatitis.

  • Gallstones

    Gallstones are lumps of solid material that form in your gallbladder. They are made when the digestive juice called bile gets hard and stone-like. Gallstones can be as small as a grain of sand or as big as a golf ball. Your gallbladder may form 1 large stone, hundreds of tiny stones, or both sizes at the same time.

  • Gangrene

    Gangrene happens when blood flow to tissues is cut off. This causes the tissue to die.

  • Gas in the Digestive Tract

    Everyone has gas. It may be painful and embarrassing, but it is not dangerous. Your body gets rid of gas by burping or by passing it through your rectum. Most people make about 1 to 4 pints of gas a day. It is common to pass gas about 14 times a day.

  • Gastric Restrictive Surgery

    Gastric restrictive surgery is a type of bariatric surgery or weight loss surgery. It limits the amount of food you can eat. This surgery may be used to treat severe obesity when diet, exercise, and medicine have failed.

  • Gastritis

    Gastritis is when your stomach lining gets red and swollen (inflamed). Your stomach lining is strong. In most cases acid does not hurt it. But it can get inflamed and irritated if you drink too much alcohol, eat spicy foods, or smoke.

  • Gastroesophageal Reflux Disease (GERD)/Heartburn

    GERD (gastroesophageal reflux disease) is a digestive disorder. It is caused when gastric acid from your stomach flows back up into your food pipe or esophagus.
