Key Takeaways:
  • Lactose intolerance is the inability to digest lactose, a sugar found in dairy products, due to low lactase enzyme levels.
  • Symptoms include bloating, diarrhoea, and abdominal pain after consuming dairy.
  • Can be managed through dietary adjustments, lactose- free alternatives and enzyme supplements.

What Is Lactose Intolerance?

Lactose intolerance is a common digestive disorder caused by the body’s inability to break down lactose, a sugar found in milk and other dairy products. This occurs due to insufficient levels of lactase, the enzyme needed to digest lactose, in the small intestine.

Symptoms of Lactose Intolerance

Symptoms typically appear within 30 minutes to 2 hours after consuming dairy and may include:

  1. Bloating - Caused by undigested lactose fermenting in the colon.
  2. Diarrhea - A result of water being drawn into the colon due to undigested lactose.
  3. Abdominal Pain and Cramps - Triggered by gas and intestinal discomfort.
  4. Flatulence - Gas buildup due to lactose fermentation.
  5. Nausea - Sometimes accompanied by vomiting.

How to Manage Lactose Intolerance

  1. Dietary Adjustments:
    • Limit or avoid dairy products containing lactose, such as milk, cheese, and ice cream.
    • Opt for lactose-free dairy alternatives like almond milk, soy milk, or oat milk.
  2. Enzyme Supplements:
    • Over-the-counter lactase enzyme supplements can help digest lactose when taken with dairy-containing meals.
  3. Monitor Your Diet:
    • Be mindful of hidden sources of lactose in processed foods, such as baked goods, salad dressings, and soups.
Can You Develop Lactose Intolerance?

Yes, lactose intolerance can develop at any age. While some people are born with a genetic predisposition to lactose intolerance, others may develop it later in life due to:

FAQs

1. Is lactose intolerance the same as a dairy allergy?

No, a dairy allergy is an immune response to dairy proteins, while lactose intolerance is a digestive issue.

2. Can you test for lactose intolerance?

Yes, tests such as hydrogen breath tests or stool acidity tests can diagnose lactose intolerance.

3. What happens if you ignore lactose intolerance?

Consuming dairy despite intolerance can lead to prolonged digestive discomfort and nutrient malabsorption.

Conclusion

Lactose intolerance, while inconvenient, is highly manageable with the right dietary choices and strategies. By understanding your triggers and opting for lactose-free alternatives, you can maintain a balanced and enjoyable diet.
