Are food intolerances causing your bloating?

At first glance, many people assume it’s just “something they ate.” However, the body’s response to food intolerances can be surprisingly complex, involving immune reactions, digestive imbalances, or even a compromised gut barrier.

At Randox Health, we’re here to help you identify the root of your discomfort with our new Food Sensitivity Test, from the comfort of your own home.

Before we dive into the test, let’s clarify the key differences between food allergies, food sensitivities, and food intolerances and explore the – often overlooked – role of leaky gut.

What are food intolerance symptoms?

Food intolerance symptoms arise when your digestive system struggles to properly process certain foods. They are typically more delayed and unpredictable when compared to food allergy reactions, which cause an immediate immune response.

Symptoms of food intolerances include:

Bloating
Stomach pain
Gas
Diarrhoea or constipation
Headaches
Nausea
Low mood or irritability

It’s possible that these symptoms will appear hours or even days after consuming the trigger food, making them difficult to trace without proper testing.

Food Allergy vs. Food Sensitivity vs. Food Intolerance

Food Allergy

An allergy involves a swift, often dangerous immune response (IgE antibodies) to specific foods, with common symptoms including hives, swelling and in severe cases, anaphylaxis.

Food Sensitivity

This involves a delayed immune response (IgG antibodies) to specific foods, triggering inflammation and a range of symptoms similar to intolerances – but immune-driven

Food Intolerance

Food intolerance is a non-immune reaction, typically involving the digestive system. For example, lactose intolerance occurs due to a lack of the enzyme lactase and leads to food intolerance symptoms like bloating and gas.

The Randox Health Food Sensitivity Test detects IgG responses to over 200 foods and drinks and helps you pinpoint hidden triggers to help limit your food intolerance symptoms.

Could Leaky Gut be making things worse?

Many people experiencing food intolerance symptoms may also be dealing with leaky gut syndrome. When the gut lining is damaged – due to stress, diet or medications – undigested food particles can leak into the bloodstream and this triggers an immune response, which can amplify symptoms like:

Chronic bloating
Fatigue
Headaches
Skin conditions
Increasing food sensitivities over time

To achieve long-term relief from leaky gut and improve general immune dysfunction, it is essential to heal the gut.
