Cholestasis is a condition where the flow of bile from the liver to the duodenum is impaired. [1] The two basic distinctions are: [1] obstructive type of cholestasis, where there is a mechanical blockage in the duct system that can occur from a gallstone or malignancy, and
Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis). [1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
Acid lipase disease or deficiency is a name used to describe two related disorders of fatty acid metabolism. Acid lipase disease occurs when the enzyme lysosomal acid lipase that is needed to break down certain fats that are normally digested by the body is lacking or missing. This results in the toxic buildup of these fats in the body's cells ...
The weight loss drug orlistat is known to increase the risk of gallstones. [28] Cholecystokinin deficiency caused by celiac disease increases risk of gallstone formation, especially when diagnosis of celiac disease is delayed. [29] Pigment gallstones are most commonly seen in the developing world.
Some researchers claim that obesity has protective effects against lipotoxicity as it results in extra adipose tissue in which excess lipids can be stored. Others claim obesity is a risk factor for lipotoxicity. Both sides accept that high fat diets put patients at increased risk for lipotoxic cells.
Deficiency of this enzyme will increase the possibility of cholesterol gallstones. [13] Disruption of CYP7A1 from classic bile acid synthesis in mice leads to either increased postnatal death or a milder phenotype with elevated serum cholesterol. [11]
Biliary colic, also known as symptomatic cholelithiasis, a gallbladder attack or gallstone attack, is when a colic (sudden pain) occurs due to a gallstone temporarily blocking the cystic duct. [1] Typically, the pain is in the right upper part of the abdomen, and can be severe. [2] Pain usually lasts from 15 minutes to a few hours. [1]
Lysosomal acid lipase deficiencies occur when a person has defects (mutations) in both copies of the LIPA gene. Each parent of a person with LAL deficiency carries one copy of the defective LIPA gene. With every pregnancy, parents with a son or daughter affected by LAL deficiency have a 1 in 4 (25%) chance of having another affected child.
