Overview

Digestive enzymes are crucial for how our bodies decompose food and absorb essential nutrients. Many Australians seek information about digestive enzymes when dealing with problems such as bloating, indigestion, IBS, or food intolerances. These enzymes transform the food we consume into usable energy and nutrients for our bodies. When enzyme production is insufficient or ineffective, digestion can be troublesome.

What are digestive enzymes?

Digestive enzymes are proteins that help break down food into smaller components for nutrient absorption. The body naturally produces them, primarily in the salivary glands, stomach, pancreas, and small intestine. Each enzyme works on a specific food type, such as carbohydrates, proteins, or fats, allowing efficient digestion.

Types of digestive enzymes and what they do

The table below outlines the main digestive enzymes, where they are produced, and their functions.

Digestive enzyme	Produced by	Breaks down	Examples of food digested
Amylase	Salivary glands, pancreas	Carbohydrates	Bread, pasta, potato
Protease	Stomach, Pancreas	Proteins	Meat, eggs, legumes
Lipase	Pancreas	Fats	Oils, butter, nuts
Lactase	Small intestine	Lactose	Dairy products
Sucrase and maltase	Small intestine	Sugars	Fruits, sweets, grains

How digestive enzymes work in the body

• Food enters through the mouth, where salivary enzymes start to break down carbohydrates.
• In the stomach, acids and enzymes further digest food, particularly proteins.
• The pancreas releases digestive enzymes into the small intestine.
• Nutrients are absorbed through the intestinal lining and into the bloodstream.
• Waste products advance to the large intestine and are eventually eliminated.

This process enables the body to access vitamins, minerals, and energy from food.

Signs you may have low digestive enzymes

Common signs of low digestive enzyme activity include:

• Bloating after eating
• Excessive gas or cramping
• Watery, pale, or floating stools
• A feeling of fullness after eating small amounts
• Unexplained weight loss
• Chronic diarrhoea
• Persistent indigestion

These symptoms may overlap with conditions like IBS, coeliac disease, and pancreatic insufficiency, emphasising the need for medical evaluation.

Common digestive enzyme problems in Australia

Multiple health issues in Australia are associated with digestive enzyme dysfunction, including:

• Lactose intolerance, which is quite prevalent and results from insufficient lactase levels
• Pancreatic insufficiency, often linked to pancreatitis or cystic fibrosis
• Coeliac disease, which harms the gut lining and disrupts enzyme functionality and absorption of nutrients
• Irritable bowel syndrome (IBS), where digestion is disturbed even without inflammation

Each condition requires a tailored management approach.

Foods that naturally boost digestive enzymes

Certain foods feature natural enzymes that may promote digestion, especially for mild symptoms:

• Pineapple (contains bromelain, a type of protease)
• Papaya (contains papain, a type of protease)
• Yoghurt and kefir (boost lactase production through probiotics)
• Ginger
• Sauerkraut and kimchi
• Avocado (contains lipase)

While these foods may aid digestion, they are not substitutes for managing underlying medical issues.

Digestive enzyme supplements: do they work?

Digestive enzyme supplements can benefit some individuals, such as those suffering from lactose intolerance or pancreatic insufficiency. Many over-the-counter options are available in Australia, but they aren’t universally effective for everyone.

When selecting a supplement, consider:

• The specific type of enzyme included
• Whether the product is registered in Australia
• Matching the enzyme to your symptoms (for instance, lactase for dairy-related problems)
• It’s advisable to consult a healthcare professional before using them long-term.

When to see a GP

You should see a doctor if you experience:

• Chronic bloating or abdominal discomfort
• Unintentional weight loss
• Oily or floating stools
• Severe or persistent reflux
• Symptoms lasting more than two weeks
• Digestive issues in children or adolescents

A GP may recommend blood tests, stool analyses, or a referral to a gastroenterologist.

If you experience severe abdominal pain, difficulty breathing, or any life-threatening symptoms, call 000 immediately or visit your nearest Emergency Department (ED).

How Hola Health can help

Hola Health’s online GPs can support Australians facing digestive issues by:

• Assessing symptoms via telehealth
• Guiding digestive enzyme usage
• Prescribing medications for symptom management, where clinically appropriate
• Referring patients to gastroenterologists if necessary
• Offering quick access to care from anywhere in Australia.

Note: While telehealth is a convenient option for initial advice, some digestive symptoms require a physical examination to diagnose. Your online GP will advise if an in-person assessment is necessary.

Conclusion

Digestive enzymes are crucial for breaking down food and promoting healthy digestion. While mild enzyme deficiencies may improve through dietary modifications or supplements, persistent digestive issues should be addressed. Collaborating with a GP to identify the root cause ensures safe and effective management. With appropriate assistance, most individuals can enhance digestion and minimise discomfort.
