Amylase is an enzyme that is normally present only in very low levels in the blood. Amylase, along with other enzymes, is produced by the pancreas to digest carbohydrates. It is released into the duodenum (the first part of the small intestines) in the digestive tract where it assists in food breakdown. Amylase is also produced by other organs in the body, particularly, the salivary glands.
Helicobacter pylori (H. pylori) is a type of bacteria. These germs can enter your body and live in your digestive tract. After many years, they can cause sores, called ulcers, in the lining of your stomach or the upper part of your small intestine. For some people, an infection can lead to stomach cancer.
