Digestive Enzymes Are Important During Chemotherapy

Digestive Enzymes Are Important During Chemotherapy

Your body makes enzymes in the digestive system, including the mouth, stomach, and small intestine. The largest share is the work of the pancreas.

Digestive enzymes help your body break down carbohydrates, fats, and proteins from food. This is necessary to allow for the absorption of nutrients and to maintain optimal health. Without these enzymes, the nutrients in your food go to waste.

Certain health conditions can interfere with the production of digestive enzymes.

When a lack of digestive enzymes leads to poor digestion and malnutrition, it’s called exocrine pancreatic insufficiency (EPI). When that happens, you can add digestive enzyme replacement before meals to help your body process foods effectively.

How do digestive enzymes work?

When the pancreas doesn’t naturally secrete digestive enzymes, it affects your body’s ability to break down the foods you eat and absorb nutrients. This can lead to malnutrition as well as symptoms such as bloating, cramping, and diarrhoea.

Replacement digestive enzymes take the place of natural enzymes, helping to break down carbohydrates, fats, and proteins from the foods you eat. Then the nutrients are absorbed into your body through the wall of the small intestine and distributed through the bloodstream.

As a result, replacement digestive enzymes can help prevent malabsorption and related digestive discomforts.

Because they’re meant to mimic your natural pancreatic enzymes, replacement digestive enzymes must be taken just before you eat. That way, they can do their work as food hits your stomach and small intestine.

In some cases, you may break up the dose. For example, if you’re eating a large meal that takes longer than usual to eat, or if you’re a slow eater, your doctor may recommend taking half the dose at the start of the meal and the rest halfway through your meal.

If you don’t take replacement digestive enzymes with food, they won’t be of much use.

Types of digestive enzymes

The main types of enzymes are:

  • Amylase. This enzyme breaks down carbohydrates, or starches, into sugar molecules. Insufficient amylase can lead to diarrhoea.
  • Lipase. This works with liver bile to break down fats. If you don’t have enough lipase, you’ll be lacking in fat-soluble vitamins such as A, D, E, and K.
  • Protease. This enzyme breaks down proteins into amino acids. It also helps keep bacteria, yeast, and protozoa out of the intestines. A shortage of protease can lead to allergies or toxicity in the intestines.

Replacement enzyme medications and supplements come in many forms with varied ingredients and dosages.

Pancreatic enzyme replacement therapy (PERT) is available only by prescription. These medications are usually made from pig pancreases. They’re subject to the Food and Drug Administration’s (FDA) approval and regulation.

Some prescription enzymes contain pancrelipase, which is made up of amylase, lipase, and protease. These medications are usually coated to prevent stomach acids from digesting the medication before it reaches the intestines.

Dosage varies from person to person based on weight and eating habits. Your doctor will want to start you at the lowest possible dose and make adjustments as needed.

Natural sources of enzymes

Certain foods contain digestive enzymes, including:

  • avocados
  • bananas
  • ginger
  • honey
  • kefir
  • kiwi
  • mangos
  • papayas
  • pineapples
  • sauerkraut

Supplementing your diet with some of these foods may aid digestion.
