Listen to your body: Telltale signs of lactose intolerance you shouldn’t ignore


Lactose intolerance is a common digestive issue that affects people worldwide. If you’ve been experiencing discomfort after consuming dairy products, you might be wondering if lactose intolerance is the culprit.

In this article, we’ll explore seven signs that could indicate you are lactose intolerant. Recognising these symptoms is the first step toward managing your diet and improving your digestive health.

Bloating and Gas:


One of the primary indicators of lactose intolerance is bloating and excessive gas after consuming dairy. If you find yourself feeling uncomfortably full and gassy shortly after enjoying a milkshake or cheese-heavy dish, your body might be struggling to break down lactose.


Frequent bouts of diarrhea, especially after consuming dairy products, could be a sign of lactose intolerance. If your digestive system has difficulty processing lactose, it can lead to an upset stomach and loose stools.

Stomach Cramps:

Experiencing abdominal pain or cramps after consuming dairy may be a clear signal of lactose intolerance. These discomforting sensations are often a result of your body’s struggle to digest lactose effectively.

Nausea and Vomiting:

If you frequently feel nauseated or experience vomiting after consuming dairy, it could be a sign that your body is unable to tolerate lactose. Pay attention to these symptoms, especially if they occur consistently after consuming milk-based products.


While diarrhea is a common symptom, some people with lactose intolerance may experience constipation. This occurs as the body attempts to compensate for the inefficient digestion of lactose by slowing down bowel movements.


Lactose intolerance can sometimes lead to nutrient malabsorption, particularly calcium. A deficiency in essential nutrients may result in fatigue and overall weakness. If you’re consistently tired and suspect lactose intolerance, it’s essential to address your dietary habits.

Unexpected Weight Loss:

Unexplained weight loss can be a less common but serious sign of lactose intolerance. If your body is not absorbing nutrients properly due to lactose intolerance, it may lead to weight loss over time. Consult with a healthcare professional if you notice a significant and unintended change in your weight.

If you’re experiencing any combination of these signs, it’s crucial to consult with a healthcare professional for a proper diagnosis. Managing lactose intolerance often involves adjusting your diet to limit or avoid dairy products. Understanding these common symptoms will empower you to make informed choices about your nutritional intake and promote a healthier digestive system.
