Lipase is an enzyme that hydrolyzes lipids (breaks down fats). Fats require special digestive action before absorption because the end products must be carried in a water medium (blood & lymph) in which fats are not soluble. It is the primary digestant used to split fats into fatty acids and glycerol. It helps reduce cholesterol and triglycerides. It aids weight loss; may reduce the size 'of gallstones; increases cell permeability so that nutrients can enter and wastes can exit. A common symptom of lipase deficiency is muscle spasms, which occur across the upper shoulders, neck or rectum.
