Question

Help with the last question please? Briefly, discuss the role(s) of bile acids in lipid digestion. You response should include the terms: detergent(s), emulsification, lipid droplet(s), micelle(s), and cholesterol esterase. Females with severe Celiac Disease often exhibit symptoms such as steatorrhea as well as conditions such as well as conditions such as osteopenia at the time of initial diagnosis of the disease. Using your understanding of human nutrition, provide mechanistic explanations for the presence of steatorrhea and osteopenia in these individuals.

Explanation / Answer

Coeliac disease is an autoimmune disorder of small intestine. Small intestine is the part of digestive system in which all the types of nutrients are completely digested and absorbed into the body. The villi of small intestine increase the surface area of small intestine. The symptoms of this disease include chronic constipation, diarrhea, failure to thrive, anemia, pain, and discomfort in digestive tract.

Steatorrhea is a condition in which the abnormal amount of fat is excreted out with the feces. The absorption of fat in small intestine is based on bile, pancreatic lipase, and normal intestine function. In Coeliac disease, due to abnormality in small intestine, the fat is not absorbed into the body and is excreted with feces.

Osteopenia is a condition in which the bone mineral density gets reduced. In coeliac disease, the abnormality in absorption of minerals in small intestine decreases the concentration of minerals in blood. Thus, to maintain the blood mineral concentration, bone resorption occurs, which results in release of calcium into the blood. This leads to bones fragility.
