Lactose Intolerance: More Common Than You Think

Lactose Intolerance: More Common Than You Think


Lactose intolerance is a prevalent digestive disorder that affects a significant portion of the global population. While many people have heard of lactose intolerance, few may fully grasp its prevalence and the impact it has on individuals' daily lives. In this blog post, we'll explore just how common lactose intolerance is, its causes, symptoms, and ways to manage it for a more comfortable and symptom-free life.

The Prevalence of Lactose Intolerance

Lactose intolerance is more common than you might imagine. It is estimated that approximately 65% of the world's population has some degree of lactose intolerance. This statistic varies by region and ethnicity, with certain groups being more susceptible to lactose intolerance than others.

Causes of Lactose Intolerance

Lactose intolerance occurs when the body has a reduced ability to digest lactose, a sugar found in milk and dairy products. This reduced ability is typically due to a deficiency of an enzyme called lactase, which is responsible for breaking down lactose into more easily digestible sugars, glucose, and galactose.

There are three primary types of lactose intolerance:

Primary Lactose Intolerance: This is the most common type and occurs as people age. Over time, many individuals naturally produce less lactase, leading to symptoms of lactose intolerance.

Secondary Lactose Intolerance: This form is typically temporary and arises as a result of injury to the small intestine, often due to an illness, infection, or surgery. Once the underlying condition is treated or resolved, lactase production may return to normal.

Congenital or Developmental Lactose Intolerance: In rare cases, lactose intolerance can be present from birth due to genetic mutations affecting lactase production.

Signs and Symptoms

The symptoms of lactose intolerance can vary in severity and typically manifest within a few hours after consuming foods or beverages containing lactose. Common signs and symptoms include bloating, which leads to abdominal discomfort, and gas, resulting in excessive flatulence. Diarrhea is another prevalent symptom, attributed to the body's inability to absorb lactose properly. Individuals with lactose intolerance may also experience abdominal pain and cramps, sometimes accompanied by nausea and, in more severe cases, vomiting. Audible stomach rumbling or noises are also common symptoms associated with this condition. These symptoms collectively contribute to the discomfort and digestive distress experienced by those with lactose intolerance.

Managing Lactose Intolerance

Managing lactose intolerance involves a variety of strategies aimed at minimizing symptoms and ensuring a comfortable and symptom-free life. Firstly, individuals can explore lactose-free alternatives readily available in most supermarkets, including lactose-free milk, yogurt, and cheese. Vitaminis Gut Health is a dairy-free way to incorporate probiotics, fiber and vitamins into your diet.  Over-the-counter lactase supplements can be taken before consuming lactose-containing foods to aid in the digestion of lactose.

For those with mild lactose intolerance, gradually introducing dairy products into the diet while monitoring tolerance can be an option. Plant-based milk alternatives like almond, soy, or coconut milk are readily available and can serve as substitutes for regular milk. Additionally, it's essential to read food labels carefully to identify hidden sources of lactose in processed foods and medications. 

Keeping a food diary can help pinpoint specific triggers, allowing individuals to avoid or moderate their consumption accordingly. By incorporating these strategies, individuals with lactose intolerance can effectively manage their condition and enjoy a more comfortable dietary experience.


Lactose intolerance is a common digestive disorder that affects a significant portion of the global population. While it can cause discomfort and digestive distress, managing lactose intolerance is possible through dietary modifications, the use of lactase supplements, and increased awareness of lactose-containing products. If you suspect you have lactose intolerance or experience symptoms, consult with a healthcare professional or a registered dietitian to develop a personalized plan for managing your condition and enjoying a symptom-free life.
