What Are the Symptoms of Lactose Intolerance?

So you just downed a milkshake and suddenly your belly's doing the Macarena. You're gassy, bloated, and wondering if your digestive system has just filed a formal complaint. Sound familiar? You might be lactose intolerant.

But don't stress we're here to break down what lactose intolerance really is, how to spot it, and most importantly, how to manage it (spoiler: plant-based goodness ahead!).

What Is Lactose Intolerance?

Lactose intolerance is a food intolerance where your body struggles with digesting lactose a natural sugar found in dairy foods like milk, cheese, and ice cream. The main culprit? An enzyme called lactase, which is produced in your small intestine and is responsible for breaking down lactose.

If you don't produce enough lactase, lactose ends up undigested in your gut, where it meets your gut bacteria and turns into… well, unpleasant symptoms.

There are four main types:

• Primary lactose intolerance: The most common, gradually developing with age.

• Secondary lactose intolerance: Triggered by digestive and kidney diseases, injuries, or infections.

• Developmental lactose intolerance: Sometimes seen in premature babies.

• Congenital lactose intolerance: A rare inherited condition where babies produce little to no lactase.

Lactose Intolerance Symptoms: What to Look Out For

So, what are the symptoms of lactose intolerance?

• Bloating

• Diarrhoea

• Gas (hello, toot town)

• Stomach pain or cramps

• Nausea

• Occasionally vomiting

These symptoms of lactose intolerance can vary depending on how much lactose you've consumed and how low your lactase levels are. Some people can tolerate hard cheeses or small amounts of milk, while others react to even a splash in their coffee.

How Is Lactose Intolerance Diagnosed?

If you're regularly experiencing these symptoms, it's worth getting checked. A few ways to diagnose lactose intolerance include:

• Hydrogen breath test: Measures hydrogen gas after consuming lactose (undigested lactose = more gas).

• Stool acidity test: More common in children.

• Blood glucose test: Tracks blood sugar response after lactose consumption.

It's important to differentiate lactose intolerance from a milk allergy or cow's milk allergy, which involves the immune system and can cause a serious allergic reaction. A milk allergy is a food allergy and is very different from lactose intolerance.

What Causes Lactose Intolerance?

The main causes of lactose intolerance boil down to lactase deficiency or lactase production that decreases over time. This can be genetic, linked to ethnicity, age, or due to digestive tract damage from illness or surgery.

Some people develop lactose intolerance after childhood. Others might experience lactose malabsorption due to gut health issues or other foods affecting the digestive system.

How to Manage Lactose Intolerance (Without Giving Up Flavour!)

Good news! You don’t have to give up delicious things to manage lactose intolerance. Here's how to keep your belly happy:

1. Follow a Lactose Free Diet

Switch to lactose free milk, lactose free formula, or dairy alternatives. Always check processed foods and labels for hidden milk solids or milk sugar.

2. Add Lactase Supplements or Drops

These help break down lactose when you're eating foods you love (cheeky cheesy pizza, anyone?).

3. Try Lactose Free Products (Like Our Plant Protein Powders)

4. Eat Dairy with Care

Some people can still tolerate small amounts of dairy products like hard cheeses or yogurt. Experiment carefully and track how your body reacts.

Can You Develop Lactose Intolerance?

Absolutely. Many people develop lactose intolerance in adulthood as lactase levels naturally decline. It's not a food allergy, but it does mean your digestive system needs a little support.

How Is Lactose Intolerance Treated?

Lactose intolerance isn't curable, but it’s super manageable. A lactose free diet, enzyme support, and plant-based products make it easy to enjoy food again. If you suspect secondary lactose intolerance, healing the underlying condition can help restore lactase production.
