Blood tests may include amylase
Amylase
An amylase is an enzyme that catalyses the hydrolysis of starch into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion. Foods that contain large amounts of starch but little sugar, such as rice and potatoes, …

Low serum levels of amylase and lipase are significantly associated with type 2 diabetes mellitus, type 1 diabetes mellitus, excess adiposity, and metabolic syndrome. The role of digestive enzymes in the pathogenesis of metabolic disorders warrants further investigations.
What does low amylase level mean?
A low amylase level may suggest a pancreas, liver or kidney problem, or cystic fibrosis. A note from Cleveland Clinic. An amylase test measures the amount of amylase in blood or urine (pee). An abnormal level of amylase can indicate a health problem, particularly a problem with the pancreas.

Which organ secretes more than 10 enzymes?
The pancreas synthesizes and secretes more than 10 enzymes, including amylase and lipase, that hydrolyze macronutrients including carbohydrate, fat and protein within the lumen of the small bowel. Serum amylase and lipase values have been widely used for the diagnosis of acute inflammatory states of the pancreas. As the secretory capacity of the pancreas decreases during the course of chronic pancreatitis, serum amylase and lipase values may decrease according to the residual functional capacity.3

What enzymes help the body digest fat?
Amylase and lipase are key digestive enzymes. Amylase helps your body break down starches. Lipase helps your body digest fats. The pancreas is a glandular organ that sits behind the stomach and produces digestive juices that empty into the small intestine. The pancreas also produces both amylase and lipase , as well as many other enzymes.
What is the function of enzymes in the body?
Enzymes are proteins produced by the body to do a particular job. The pancreas produces amylase to break down carbohydrates in food into simple sugars. The pancreas makes lipase to digest fats into fatty acids. Sugars and fatty acids can then be absorbed by the small intestine.

Why is amylase high in the blood?
High levels of amylase in the blood (hyperamylasemia) are caused by either too much of the enzyme entering the bloodstream or not enough of it being cleared (by the kidneys) [ 2 ]. Amylase will usually build up in the blood as a result of issues with the salivary glands or the pancreas.
Why is amylase used instead of blood?
When needed, urine amylase may be used instead of the blood test because it’s less invasive [ 30 ].
What is the function of amylase?
Amylase Function. Amylase is an enzyme that breaks down complex carbs into simpler ones. Digestion of carbs is extremely important since carbs are ultimately broken down into glucose – the main energy source that fuels our bodies. There are two main types of amylase – salivary and pancreatic [ 1, 2 ].
Why is amylase important?
Low levels have been linked to insulin resistance, metabolic syndrome, obesity, and diabetes. High amylase can be due to issues with the salivary glands or the pancreas, which produce this enzyme.

The most important thing is to work with your doctor to find out what’s causing your high amylase and to treat any underlying conditions!
Which gland produces amylase?
Salivary amylase is produced by salivary glands and it starts digesting food as you chew it. Pancreatic amylase is produced by the pancreas and helps digest complex sugars in your gut [ 3 ].
