What causes poor dietary fat absorption?

Poor dietary fat absorption can be caused by a variety of factors, including pancreatic insufficiency, where the pancreas doesn't produce enough digestive enzymes necessary for fat breakdown. Conditions such as celiac disease, Crohn's disease, or other gastrointestinal disorders can impair the intestinal lining's ability to absorb fats effectively. Additionally, certain surgical procedures that alter the digestive tract may also hinder fat absorption. Lastly, bile acid deficiency or dysfunction can prevent the emulsification of fats, further contributing to malabsorption.
