Lactose intolerance in adults: symptoms to recognise

Is it possible to become lactose intolerant as an adult?

Yes, that's right. Contrary to popular belief, lactose intolerance does not only affect children. It can occur at any ageeven after 30, 40 or 50 years. In reality, it is normal to produce less and less lactase (the enzyme that digests lactose) over the years. This phenomenon is called secondary lactase deficiency.

This explains why many people experience digestive problems after consuming dairy products, without necessarily making the connection immediately.

What are the most common symptoms in adults?

Here are the most frequent digestive signs related to lactose intolerance in adults :

  • Bloatingfeeling of a swollen stomach after meals
  • Abdominal crampsdiffuse or localised pain
  • Gas and flatulencesometimes associated with bowel sounds
  • Diarrhoea or, on the contrary, slow transit
  • Nausea Occasionally, especially after meals rich in dairy products
  • Digestive fatiguea feeling of heaviness and loss of energy

These symptoms generally appear between 30 minutes and 2 hours after lactose ingestion. Their intensity depends on several factors:

  • the amount of lactose consumed,
  • the type of dairy product (milk, cream, fromage frais, etc.),
  • the individual susceptibility,
  • the meal composition (a dairy product eaten on its own often leads to a faster reaction).

Symptoms that can be misleading

In adults, the symptoms of lactose intolerance are sometimes confused with other digestive disorderssuch as :

This can delay diagnosis and cause daily discomfort. If you notice recurrence of the same symptoms after milky mealsIt may be useful to test a temporary avoidance of lactose to see how it develops.

What are the signs of lactose intolerance in adults?

In adults, symptoms include bloating, cramps, gas, diarrhoea and nausea. They often appear after eating dairy products and can last for several hours.

How can you recognise lactose intolerance and not something else?

If digestive problems occur regularly after consuming milk, fromage frais or cream, and disappear without lactose, it may be a case of intolerance. An eviction test or breath test can confirm this.

At what age can you become lactose intolerant?

Lactose intolerance can appear as early as adolescence or adulthood. It is often progressive, as lactase production naturally declines with age.

What products should I look out for if I'm intolerant?

Milk, cream, unfermented yoghurt, fromage frais and dairy desserts, as well as certain ready-made meals, cold meats and medicines may contain lactose.

How can symptoms of lactose maldigestion be relieved?

You can take a lactase supplement such as LACTOLERANCE 9000 or LACTOLERANCE ULTRA before a meal containing lactose. This helps prevent digestive symptoms in adults with lactose intolerance.
