What Are Pancreatic Enzymes?

Pancreatic enzymes are produced by acinar cells in the panscris and sekred into the duodenum via the pankreatic duct.

Epidemiologie of EPI in Diabetes

EPI is more prevalent in diabetes than in the general population. In type 1 diabetes, autoimune destruction of beta cells often extends to acinar tissue, reducing enzyme output. In type 2 diabetes, chronic hyperglycemia, insulin resistance, and metabolic phynmation can damage pankreac acinar cells.

Proper Dosing and Administration

Te lipase content determines the dose, as fat digestion is the hardett to restate. A typical starting dose is 500 to 1,000 USP units of lipase per gram of dietary fat consumed. For an average meal concluing 30-50 g of fat, this translates to 15,000- 50,000 units of lipase. Capsules madd betn with te first bite of thee meail (not before or after).
