What is Lipase and Why Do We Use Them?

What is a lipase test?

Lipase is a type of digestive enzyme or "digestive juice." It helps your body digest fats. Most of your lipase is made in your pancreas, an organ located behind the lower part of your stomach. Lipase is also made in your salivary (spit) glands and in your stomach.

It's normal to have a small amount of lipase in your blood. But if the cells of your pancreas are damaged, they will release larger amounts of lipase. So high levels of lipase in your blood may mean you have pancreatitis, (an inflamed, swollen pancreas) or another type of pancreatic disease. A lipase tests can help diagnose these conditions and others.

Other names: serum lipase, lipase, LPS

Most people do not need additional lipase. However, people with the following conditions may find lipase supplements helpful.

Celiac disease

Celiac disease is a condition in which gluten (a protein found in grains) damages the intestinal tract. Symptoms include abdominal pain, bloating, weight loss, and fatigue. People with celiac disease must follow a strict diet that is free of gluten. Pancreatic enzymes have been studied as part of the treatment for celiac disease, however, it is not clear how much they help. In one study of 40 children with celiac disease, for example, those who received pancreatic enzyme therapy (including lipase), had a modest weight gain compared to those who received placebo. The weight gain happened during the first month. Taking pancreatic enzyme supplements for another month did not lead to more weight gain.

Indigestion

In a small clinical study of 18 people, supplements containing lipase and other pancreatic enzymes helped reduce bloating, gas, and fullness following a high-fat meal. These symptoms are commonly associated with irritable bowel syndrome (IBS). So some researchers speculate that pancreatic enzymes might help treat symptoms of IBS. No studies have been done to test this theory.

Cystic fibrosis

People with cystic fibrosis, an inherited condition that causes the body to produce abnormally thick, sticky mucus, often have nutritional deficiencies because mucus blocks pancreatic enzymes from getting to the intestines. Taking pancreatic enzymes as prescribed by a doctor helps improve the nutrition they get from food.
