Lactose Intolerance After Pregnancy: Understanding the Causes and Finding Relief

Pregnancy is a transformative experience that brings about many changes to a woman's body. One of these changes is an increased risk of developing lactose intolerance after pregnancy. This can be a surprising and uncomfortable condition for new mothers who may have previously enjoyed dairy products without issue. As a Registered Dietitian Nutritionist, I've worked with many clients who have experienced lactose intolerance after pregnancy, and I'm here to share some insights and tips to help manage this condition.

Understanding Lactose Intolerance After Pregnancy

Lactose intolerance is a condition that occurs when the body has difficulty digesting lactose, a sugar found in milk and other dairy products. This happens when the body doesn't produce enough lactase, the enzyme that breaks down lactose in the small intestine. When lactose isn't properly digested, it can cause uncomfortable symptoms such as bloating, gas, diarrhea, and abdominal pain.

During pregnancy, the body produces higher levels of lactase to help break down lactose and provide nutrition for the growing fetus. However, after giving birth, lactase production may decrease, leading to lactose intolerance in some women. Additionally, changes in the gut microbiome and hormonal fluctuations after pregnancy can also contribute to lactose intolerance.

Finding Relief from Lactose Intolerance

If you suspect you may have lactose intolerance after pregnancy, it's important to talk to your healthcare provider and get a proper diagnosis. In the meantime, there are some steps you can take to manage symptoms and find relief.

  1. Try lactose-free dairy products: Lactose-free dairy products, such as lactose-free milk and cheese, are available at most grocery stores and can be a good option for those with lactose intolerance. These products have been treated with lactase enzyme to break down the lactose, making them easier to digest.

  2. Choose dairy alternatives: There are many dairy alternatives available, such as soy milk, almond milk, and oat milk, that are naturally lactose-free. These alternatives can be used in place of dairy milk in recipes or enjoyed on their own.

  3. Consider probiotics: Probiotics, which are beneficial bacteria that live in the gut, may help improve lactose digestion and reduce symptoms of lactose intolerance. Talk to your healthcare provider or a Registered Dietitian Nutritionist about which probiotic supplement may be best for you.

  4. Experiment with portion sizes: Some people with lactose intolerance may be able to tolerate small amounts of lactose. Experiment with different portion sizes of dairy products to see what works for you. For example, you may be able to tolerate a small amount of cheese on a sandwich, but not a glass of milk.

  5. Be mindful of hidden sources of lactose: Lactose can be found in many unexpected foods, such as processed meats, salad dressings, and baked goods. Be sure to read food labels and look for hidden sources of lactose.


Lactose intolerance after pregnancy can be a frustrating and uncomfortable condition, but it's important to remember that there are many ways to manage symptoms and find relief. By trying lactose-free dairy products, choosing dairy alternatives, considering probiotics, experimenting with portion sizes, and being mindful of hidden sources of lactose, you can still enjoy a healthy and varied diet without discomfort. If you're struggling with lactose intolerance after pregnancy, don't hesitate to reach out to a healthcare provider or Registered Dietitian Nutritionist for support and guidance.
