When you have a glass of milk or enjoy your favorite cheese, you want to sit back and enjoy every drop or bite without any interruptions. However, for people who have lactose intolerance, this simple pleasure can be a nightmare. Lactose intolerance is a common digestive disorder that affects millions of people worldwide. Without proper knowledge and understanding, it can lead to discomfort, embarrassment, and even malnutrition. In this article, we will explore the signs and symptoms, causes, diagnosis, and coping strategies for lactose intolerance.

Signs and Symptoms of Lactose Intolerance

Lactose intolerance symptoms can vary from person to person and depend on the amount of lactose consumed. However, some of the most common signs and symptoms include:

  • Abdominal pain
  • Bloating
  • Gas
  • Nausea
  • Diarrhea
  • Constipation

If you experience any of these symptoms regularly, it is recommended to seek medical advice to make sure they are not related to any other condition.

Causes and Diagnosis of Lactose Intolerance

Lactose intolerance occurs when your body cannot digest lactose, the natural sugar found in milk and dairy products. This happens when your small intestine stops producing lactase, the enzyme that breaks down lactose into simple sugars that can be easily absorbed by your body.

In some cases, lactose intolerance can be genetic, while in others, it can develop later in life due to various factors such as aging or illness. Common conditions that can cause lactose intolerance include celiac disease, Crohn’s disease, and ulcerative colitis.

To diagnose lactose intolerance, your healthcare provider will likely recommend a lactose intolerance test. This may involve drinking a liquid containing lactose and then measuring your blood glucose levels or hydrogen breath levels over a period of time. In some cases, your doctor may also recommend a trial elimination of dairy products from your diet to see if your symptoms improve.

Effects of Lactose Intolerance on Health and Well-being

Lactose intolerance can have a significant impact on your digestive system, leading to discomfort, pain, and embarrassment. It can also impact your nutritional status, especially if you eliminate dairy products from your diet without finding suitable alternatives. Dairy products are a good source of calcium, vitamin D, and other essential nutrients that are crucial to maintaining healthy bones, teeth, and overall health.

Moreover, lactose intolerance can also affect your mental and emotional well-being, causing stress, anxiety, and embarrassment. People with lactose intolerance may feel excluded from social events or find it challenging to eat out, leading to feelings of isolation and loneliness.

Coping with Lactose Intolerance Symptoms

Fortunately, there are many ways to cope with lactose intolerance symptoms and enjoy a healthy and happy life. One effective strategy is to limit your intake of lactose-containing foods or find suitable alternatives that are lactose-free or low in lactose. Some examples of non-dairy food sources of calcium and other nutrients include leafy greens, almonds, tofu and fortified soy milk, fish, and eggs.

You can also try taking lactase enzyme supplements before eating dairy products to aid digestion. These supplements are available over-the-counter and can be taken in the form of tablets, capsules, or drops.

If you are unsure about which foods contain lactose or how to make healthy and delicious lactose-free meals, seek guidance from a registered dietitian or nutritionist who can help you develop a personalized meal plan.


Lactose intolerance is a common digestive disorder that affects many people worldwide. Understanding the signs and symptoms, causes, diagnosis, and coping strategies is crucial for managing this condition and living a healthy and happy life. If you experience symptoms of lactose intolerance, seek medical advice to receive proper diagnosis and guidance on how to manage your symptoms. Remember, lactose intolerance does not have to limit your enjoyment of food or social life.
