Do you have lactose intolerance?

What is lactose intolerance?

Lactose intolerance is not an allergy. Instead, it happens when your body doesn’t make enough of the enzyme lactase, which is needed to break down lactose in the small intestine. Without enough lactase, lactose travels to the colon where bacteria break it down, causing uncomfortable symptoms.

While lactose intolerance can be unpleasant, it is harmless on its own. Answering the following questions can help you understand if you could have lactose intolerance.

1. How soon after consuming dairy do you notice symptoms?

• Do you experience bloating, gas, diarrhea, or stomach cramps within a few hours of drinking milk, eating cheese, yogurt, or ice cream?
• Symptoms that appear quickly after dairy are a strong sign that lactose could be the culprit.

2. Do certain dairy products affect you more than others?

• Do milk or soft cheeses bother you more than hard cheeses or yogurt?
• People with lactose intolerance often tolerate small amounts of low-lactose foods better.

3. Are your symptoms consistent or occasional?

• Do you notice regular patterns, like bloating or diarrhea every time you have a glass of milk?
• Inconsistent or rare symptoms may be related to something else in your diet.

4. Do you experience symptoms at night?

• Some people with lactose intolerance get diarrhea or bloating during the night, especially after consuming dairy in the evening.

5. Have you had gut infections or other digestive conditions recently?

• Secondary lactose intolerance can happen after intestinal problems such as:
  • Stomach infections
  • Gluten intolerance (celiac disease)
  • Crohn’s disease or other intestinal inflammation
• If you recently had one of these, your intolerance may be temporary.

6. Do you feel better when you avoid dairy?

• Try a short experiment: remove dairy from your diet for 1–2 weeks and note whether symptoms improve.
• If discomfort decreases, it’s likely that lactose is the problem.

7. Are you getting enough calcium and vitamin D?

• If you cut out dairy, make sure you are replacing it with lactose-free alternatives or other calcium-rich foods.
• This ensures strong bones and prevents deficiencies.

What to do next

If most of your answers point to dairy as the trigger:

1. Consult a healthcare professional for confirmation.
2. Consider lactose-free or reduced-lactose products.
3. Try lactase enzyme supplements if you want to enjoy regular dairy.
4. Monitor your symptoms and adjust your diet accordingly.

Summary

Lactose intolerance is common and manageable. By paying attention to your body and answering these questions, you can identify whether lactose may be causing your digestive discomfort and take steps to eat comfortably without giving up essential nutrients.
