INTRODUCTION
Lactose intolerance is a common issue for individuals with celiac disease due to gluten-induced intestinal damage. The small intestine produces lactase, an enzyme responsible for breaking down lactose, the sugar found in dairy products. When gluten damages the intestinal lining, lactase production decreases, making it difficult to digest dairy. This results in uncomfortable symptoms like bloating, gas, and diarrhoea. The good news is that easing a lactose intolerance and adopting a gluten-free diet can allow the gut to heal, restoring lactase production in many individuals. Over time, this dietary change can reduce digestive discomfort and improve overall gut health, making it easier for lactose intolerants.
CELIAC DISEASE AND LACTOSE INTOLERANCE
Celiac disease is an autoimmune condition where the ingestion of gluten triggers an immune response, causing inflammation and damage to the small intestine. The damage mainly affects the villi—tiny, finger-like projections responsible for nutrient absorption. Since the villi also produce lactase, any harm to them can lead to a temporary inability to digest lactose properly. This is why many people with newly diagnosed celiac disease experience lactose intolerance. However, once the gut heals through a strict gluten-free diet, lactase production can often resume, reducing or even eliminating symptoms of lactose intolerance.
SYMPTOMS OF LACTOSE INTOLERANCE IN INDIVIDUALS
Common symptoms include:
- Bloating: Excess gas production in the intestines due to undigested lactose.
- Diarrhoea: Lactose draws water into the intestines, leading to loose stools.
- Abdominal pain: Cramping and discomfort occur as the digestive system struggles to break down lactose.
- Gas: Fermentation of lactose in the colon leads to excessive flatulence.
- Nausea: Some individuals experience a feeling of sickness shortly after consuming dairy.
Eliminating both gluten and dairy temporarily may help pinpoint the cause of your discomfort.
HOW A GLUTEN-FREE DIET SUPPORTS GUT HEALING
The best way to restore gut health and improve lactose digestion is by eliminating gluten from your diet. When gluten is removed, the inflammation in the small intestine decreases, allowing the villi to regenerate and function properly again. This healing process takes time—some people notice improvements in a few weeks, while others may require several months or longer. As gut health improves, nutrient absorption increases, and many individuals regain the ability to digest lactose without discomfort.
TEMPORARY VS PERMANENT LACTOSE INTOLERANCE
Understanding the difference between temporary and permanent lactose intolerance is crucial for managing your diet effectively:
- Temporary lactose intolerance: Often occurs in individuals with celiac disease due to gluten-induced intestinal damage. Once the gut heals, lactase production resumes, allowing most people to tolerate dairy again.
- Permanent lactose intolerance: Some people naturally produce lower levels of lactase as they age, leading to lifelong difficulty digesting dairy. In such cases, dairy alternatives may be the best option.
For those with temporary intolerance, patience is key. A gluten-free diet can make a significant difference in how the body processes lactose over time.
ALTERNATIVES FOR THOSE WITH GLUTEN SENSITIVITY
Many nutritious dairy-free alternatives are naturally gluten-free:
- Milk substitutes: Almond milk, coconut milk, oat milk, and rice milk provide excellent dairy-free options.
- Cheese alternatives: Dairy-free cheeses made from cashews, almonds or soy offer great taste and texture.
- Yoghurt options: Coconut-based and almond-based yoghurts with probiotics support gut health.
- Butter substitutes: Olive oil, avocado and dairy-free margarine serve as adequate replacements.
These alternatives provide similar textures and flavours to dairy products, ensuring you don’t miss out on essential nutrients or enjoyable meals.
Reintroducing Dairy After Gut Healing
If you want to try adding dairy back into your diet, follow these steps:
- Start with small amounts: Begin with aged cheeses or yoghurt, which contain lower levels of lactose.
- Monitor symptoms: Track any bloating, discomfort or digestive distress after consuming dairy.
- Choose lactose-free options: If symptoms persist, try lactose-free milk or dairy products.
- Use lactase supplements: Taking lactase enzyme pills can help break down lactose for easier digestion.
- Listen to your body: If discomfort continues, it may be best to stick with dairy-free alternatives.
Taking a gradual approach helps prevent digestive distress and allows you to determine your tolerance levels effectively.
ADDITIONAL GUT-FRIENDLY STRATEGIES
Aside from eliminating gluten and managing dairy intake, adopting additional gut-friendly habits can further improve digestive health:
- Increase fibre intake: Whole, gluten-free grains like quinoa, brown rice and millet aid digestion.
- Stay hydrated: Drinking plenty of water supports overall digestion and reduces bloating.
- Exercise regularly: Physical activity promotes gut motility and reduces digestive discomfort.
- Limit processed gluten-free foods: Many gluten-free packaged products are low in fibre and nutrients, which can slow gut healing.
These small changes can have a significant impact on digestion and overall gut function.
CONCLUSION
Lactose intolerance is a common issue among individuals with celiac disease caused by gluten-related intestinal damage. However, by following a strict gluten-free diet, the gut can heal, allowing many people to regain their ability to digest lactose. In the meantime, dairy alternatives provide nutritious options for those who experience discomfort. By prioritising gut health, reducing inflammation, and making mindful dietary choices, individuals can improve digestion, alleviate lactose intolerance, and adopt a gluten-free diet to enjoy a more comfortable, balanced lifestyle.
