Side effects of digestive enzymes include trouble breathing, difficulty talking, throat inflammation and peeling skin. Abdominal pain, headaches, chest tightness, constipation and vomiting are other side effects of consuming digestive enzymes. Additionally, coughing, stuffy nose, pain in the neck, ear pain and nosebleeds are also side effects of taking digestive enzymes, according to MedicineNet.
Digestive enzymes increase the risk of developing fibrosing colonopathy, which causes colon inflammation and scarring. People allergic to pork should avoid taking digestive enzymes. Additional side effects include itching, rashes, wheezing and heartburn. A patient who experiences any of these symptoms should seek immediate medical attention, says MedicineNet.
Digestive enzymes are proteins that assist the body in breaking down food. The pancreas produces digestive enzymes. The inability of the pancreas to produce digestive enzymes creates a need for oral digestive enzymes. Medical conditions treated with digestive enzymes include cystic fibrosis, chronic pancreatitis, pancreatic cancer and Shwachman-Diamond syndrome. Celiac disease, Crohn's disease and the deficiency of pancreatic enzymes also require oral digestive enzymes, states MedicineNet.
People with a history of acute pancreatitis should inform their doctor before taking digestive enzymes. They should also inform the doctor of any medication they are taking, including herbal products, says WebMD.
