Dairy products have been a major part of the European diet since early childhood. They are an important source of protein and provide the body with the necessary amount of calcium for strong bones, as well as other vitamins such as D, B12, B2 (riboflavin), and minerals like phosphorus, potassium, and magnesium.

Nowadays, however, many people hear the diagnosis “lactose intolerance” and are forced to make fundamental changes to their lifestyle and diet. Often, this diagnosis comes as an answer to the question of why various symptoms occur—such as gas, bloating, stomach pain, and sometimes even more serious ones like vomiting and diarrhea. Lactose intolerance is not just a trendy diagnosis – it is a very real issue that affects millions of people around the world.

If you are among this considerable number, then understanding this intolerance and learning how to manage it is essential. In this article, we will explore everything important on the topic—from the symptoms and diagnosis to effective methods for control and treatment.

What is lactose intolerance?

Lactose and the enzyme lactase

Milk and dairy products contain a natural sugar called lactose. When we consume them, our body uses an enzyme called lactase to break them down and absorb the beneficial nutrients and vitamins they contain. Lactase is produced in the small intestine and breaks lactose down into two simpler sugars – glucose and galactose. When, for one reason or another, the amount of lactase is reduced, this process doesn’t occur, and the lactose remains undigested, passing into the large intestine where it causes a range of unpleasant symptoms.

Types of lactose intolerance

There are three main types of lactose intolerance:

Primary – The most common type, affecting the largest number of people. It occurs because lactase production naturally decreases with age.

Secondary – This type develops because of an illness or injury to the intestines (e.g., gastroenteritis, celiac disease).

Congenital (congenital alactasia) – This form is very rare and appears at birth when a baby is unable to break down lactose even in breast milk.

Why do so many people suffer from lactose intolerance?

The percentage of people worldwide who suffer from some form of lactose intolerance is extremely high—around 70%. In certain ethnic groups (e.g., Asians, Africans, Latin Americans), the percentage is even higher. Genetics play a crucial role—in some regions, people have inherited genes that keep lactase activity active into adulthood, while in others this function weakens over time.

In Bulgaria, lactose intolerance is not uncommon, but the percentage is lower—around 25–30% of Bulgarians are affected. Some local dairy products, such as yogurt, are better tolerated by the body because fermentation breaks down part of the lactose.

What are the symptoms and how can it be recognized?

Digestive issues

As already mentioned, the most common symptoms involve digestive problems, usually appearing 30 minutes to 2 hours after consuming milk or other dairy products. These include:

• Bloating
• Gas
• Stomach pain and cramps
• Nausea
• Diarrhea

These reactions are caused by the fermentation of undigested lactose by bacteria in the large intestine, which produces gases and organic acids. Symptoms vary depending on the amount of lactose consumed and the individual’s level of lactase activity. For example, one glass of milk may not cause issues for someone with a mild form of intolerance, but could trigger severe symptoms in someone more sensitive. Symptoms usually last a few hours, but in stronger reactions, they can persist for up to 24 hours.

Related symptoms beyond the stomach

In addition to digestive issues, some people also report experiencing other symptoms, including:

• General fatigue and weakness
• Irritability
• Skin rashes
• Headaches

It’s important to emphasize that these symptoms are not directly caused by lactose itself but may result from chronic discomfort and an imbalanced gut microbiota.

Diagnosis

Elimination diet

The first step is personal observation—that is, noticing if you experience stomach discomfort after consuming dairy products. In such cases, it’s a good idea to try an elimination diet: avoid milk and lactose-containing dairy products for at least 2–3 weeks. Then, slowly reintroduce them into your diet while monitoring your body for any reactions.

Medical tests

If the symptoms occur frequently and you strongly suspect an intolerance, consult a doctor. They may recommend:

Hydrogen breath test – measures the amount of hydrogen in the exhaled air after consuming lactose. Elevated levels indicate fermentation of undigested lactose.

Lactose tolerance blood test – after drinking a lactose-containing beverage, blood glucose levels are monitored. Since lactose is a sugar, if there is no increase in glucose—meaning it hasn’t entered the bloodstream—it indicates that your body is not properly digesting it.

The difference from a milk allergy

It’s important to note that lactose intolerance is not a milk allergy. The latter is an immune reaction to milk protein and can be life-threatening. Symptoms include rashes, swelling, shortness of breath, and anaphylaxis. If you suspect a milk allergy, be sure to consult an allergist.

Treatment and ways to manage the condition

Diet

The most effective approach is to limit or completely avoid products containing lactose. This may sound extreme or complicated, but it doesn’t mean the end of delicious food—just more mindful planning. Products that typically contain lactose include milk, cheese, yogurt, sour cream, butter, and even some processed foods you might not suspect, such as baked goods, ready-made dressings, and more.

Over time, you’ll start to recognize which foods trigger a strong reaction. They are not the same for everyone—some people tolerate hard cheeses with low lactose content, like Parmesan and Cheddar, quite well, while others do not. The amount can also be a determining factor—for example, you might have no problem drinking your morning coffee with a bit of milk or cream, but a full glass of milk may be out of the question.

Taking a lactase supplement

Sometimes it’s not easy to avoid lactose 100%, especially if you enjoy dairy products, are about to travel, or have an occasion where planning your meals might be more difficult. In such cases, enzyme supplements containing lactase, such as Estocal, can help. They are taken before consuming lactose-containing foods and aid in breaking down lactose in the intestines.

The formula of Estocal contains a high amount of the enzyme—7,000 FCC units in the recommended dose of two tablets—making it suitable even for meals with higher lactose content. The supplement is taken right before consuming dairy products and not only helps digest lactose but also significantly reduces the risk of bloating, gas, and abdominal discomfort. The product is a practical solution for people who don’t want to completely give up dairy and is especially useful when eating out, while traveling, or at social events.

Probiotics and a healthy gut flora

The state of the gut microbiota plays a key role not only in lactose tolerance but also in overall digestion and immunity. Probiotics—beneficial bacteria that support digestion and gut health—are largely responsible for maintaining that balance. Some studies suggest that taking specific probiotic strains may improve lactose tolerance in people with mild to moderate intolerance.

The best probiotic food sources include fermented foods such as kimchi, sauerkraut, pickles, as well as certain yogurts (there are lactose-free options too). There are also many probiotic supplements on the market that can be combined with a lactose-free diet.

Maintaining a healthy gut flora through a proper diet and probiotics can help alleviate symptoms and improve quality of life. A high-quality and effective pro- and synbiotic is B-protekt.  

Life without lactose – mission possible

Dairy substitutes

Today, we are fortunate to have an abundance of alternatives to traditional dairy products, making life without lactose easier than ever. Some popular substitutes include:

• Milk – soy, almond, rice, oat, coconut
• Yogurts – based on coconut, soy, or almond
• Cheeses – vegan cheeses made from cashews, almonds, or potatoes
• Cream and butter – plant-based creams and butters made from coconut or sunflower

Many of these products are fortified with calcium, vitamin D, and B12, making them excellent nutritional replacements.

Conclusion

Lactose intolerance is a common condition that can significantly affect quality of life if not recognized and properly managed. The symptoms are unpleasant but manageable—especially with the right diet, enzyme supplements, and alternative food products. Thanks to modern options, life without lactose can be not only healthy but also tasty and diverse. Don’t give up the pleasure that food brings—just make an informed choice.
