Understanding lactose intolerance in children

As a parent, it’s natural to be worried if you notice any discomfort or unusual symptoms in your child. Constant nausea or worrying skin irritation can leave you feeling anxious about their health. 

If this is your child, you’re not alone. 50% of children in the UK have one or more allergies. One of the more common issues that many parents encounter is lactose intolerance. The good news is, as lactose intolerance is so common if this is affecting your child, there is a path to a more comfortable life for them. 

Understanding lactose intolerance is crucial for parents. It’s not the same as a milk allergy, and it can be challenging to diagnose in children. However, by knowing the key symptoms to monitor, you can be better prepared to manage your child’s condition.

What is lactose intolerance?

Lactose intolerance is a common condition that affects up to 750,000 children in the UK. It happens when the body doesn’t produce enough lactase, which is an enzyme required to digest lactose in the digestive system. When there’s insufficient lactase, lactose passes through the intestines without breaking down properly, causing various gastrointestinal symptoms. It’s worth noting that lactose intolerance is not life-threatening, but it can cause discomfort for your child.

How is lactose intolerance different to a milk allergy?

It’s important to know the difference between lactose intolerance and a milk allergy. A milk allergy occurs when the immune system reacts to the proteins present in milk. This reaction can cause a range of symptoms, such as hives, itching, and even severe anaphylactic reactions. On the other hand, lactose intolerance is a digestive issue and does not involve the immune system. 

Challenges in diagnosing lactose intolerance in children

Diagnosing lactose intolerance can be tricky, especially in children. Our young ones aren’t able to articulate precisely what feels wrong, making it hard for you to pinpoint the issue. Additionally, symptoms of lactose intolerance can mimic those of other digestive disorders, such as irritable bowel syndrome or even a temporary stomach bug. On top of this, there are sneaky foods that contain hidden lactose. Your child might still be consuming lactose, even if you think you’re avoiding it, leaving you feeling confused.

Lactose intolerance symptoms to watch for

If you suspect that your child may be lactose intolerant, it is important to watch for certain symptoms that may appear after consuming dairy products. These symptoms include:

• Bloating
• Diarrhoea
• Tummy cramps
• Excessive wind
• Complaining of feeling sick

Typically, symptoms appear within a few hours of consuming dairy. If you’re observing these symptoms, it may be helpful to keep a food diary for your child, noting what they eat and any symptoms that follow. This can help you pinpoint the issue and take the necessary steps to manage your child’s lactose intolerance effectively.

What to do if you suspect lactose intolerance in your child

If you notice that your child consistently experiences discomfort after consuming dairy, it may be a good idea to test them for possible dairy intolerance. By identifying the root cause of their discomfort, you can take steps to help them lead a healthier and happier life. Additionally, if you experience any of these symptoms yourself, it may be a good idea to get tested for possible dairy intolerance.
