Description

Gallstones are the hardened deposits of bile formed in the gallbladder.

Indications

Gallstones of any size or number are frequently asymptomatic. These "silent stones" do not require treatment and can be asymptomatic for years.

A gallstone attack is recognized by colic-like pain in the upperright side of the abdomen, which is frequently accompanied by nausea and vomiting. Pain from symptomatic gallstones can range from mild to severe and can increase gradually over a period of 30 minutes to several hours. Fever and referred pain between the shoulder blades or below the right shoulder are possible symptoms.

Jaundice and itching may occur if one or more gallstones block the bile ducts and cause bilirubin to leak into the bloodstream and surrounding tissue. In this case, the levels of liver enzymes are likely to be elevated.

Gallbladder attacks frequently occur after a large meal. Attacks are most common in the late afternoon or early evening.

Gallstones that cause severe inflammation can erode through the gallbladder and into adherent bowel, potentially causing gallstone ileus.

Other complications include ascending cholangitis, which occurs when a bacterial infection causes purulent inflammation in the biliary tree, and liver and acute pancreatitis, which occurs when the bile ducts become blocked, preventing active enzymes from being secreted into the bowel and instead damaging the pancreas. Gallbladder cancer is an uncommon complication

Risk factors

Gallstones are more common in females (especially before menopause) and people over the age of 40; the condition is more common in North and South Americans and people of European descent than in other ethnic groups. Melatonin deficiency may contribute significantly to gallbladder stones because it inhibits gallbladder cholesterol secretion, improves the conversion of cholesterol to bile, and is an antioxidant that can reduce oxidative stress to the gallbladder. Gilbert syndrome is associated with a higher risk of gallstones. Gallstones may be caused by a combination of factors, including inherited body chemistry, body weight, gallbladder motility (movement), and a low-calorie diet, according to researchers. The absence of such risk factors, however, does not rule out the formation of gallstones. Constipation; eating fewer meals per day; low intake of the nutrients folate, magnesium, calcium, and vitamin C; low fluid consumption; and, at least for men, a high carbohydrate, high glycemic load, and high glycemic index diet are all nutritional factors that may increase the risk of gallstones. Wine and whole-grain bread may reduce the likelihood of gallstones.

Rapid weight loss raises the risk of gallstones. The weight loss medication has been linked to an increased risk of gallstones.

Cholecystokinin deficiency caused by celiac disease increases the risk of gallstone formation, particularly when celiac disease diagnosis is delayed.

Pigment gallstones are most common in developing countries. Hemolytic anemia’s (such as sickle cell disease and hereditary spherocytosis), cirrhosis, and biliary tract infections are all risk factors for pigment stones. Gallstones are more likely in people who have Erythropoietic Protoporphyria (EPP). Furthermore, pron pump inhibitors have been shown to reduce gallbladder function, potentially leading to gallstone formation.

Cholesterol-lowering medications can have an impact on gallstone formation. Statins inhibit cholesterol synthesis, and there is evidence that using them may reduce the risk of developing gallstones. Fibrates raise the concentration of cholesterol in bile, and their use has been linked to an increased risk of gallstones. Bile acid malabsorption is another possibility.
