Information

Have you been feeling any of these symptoms lately?

The Food Intolerance Blood Test is recommended for individuals who have noticed one or more of the following symptoms:

Itching in the mouth or throat
Swelling of the face, lips, or mouth
Difficulty breathing or shortness of breath
Red or irritated rashes on the skin
Severe reactions to food, such as chest tightness, difficulty speaking, or dizziness

Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert

Cortisol plays a vital role in the body, assisting with stress management, inflammation control, regulation of blood pressure, metabolism, and blood sugar levels.

Excessive cortisol in the blood can lead to symptoms such as weight gain, a round face, skin marks, thinning of the arms and legs, bruising, and muscle weakness. High cortisol levels are commonly associated with Cushing’s Syndrome, the use of certain medications like steroids, or the presence of certain tumors.

On the other hand, low cortisol levels can cause symptoms like fatigue, weight loss, muscle weakness, appetite loss, and abdominal pain. These low levels are typically seen in conditions such as Addison’s disease, adrenal insufficiency, and may also result from certain infections, autoimmune disorders, or brain injuries.

Monitoring cortisol levels is essential for diagnosing these conditions and managing their effects on overall health.

Additional Information

If you suspect you may have a food intolerance, a food intolerance test can help identify the foods your body struggles to digest or absorb. These tests are a valuable tool in pinpointing which foods may be causing discomfort.

Home Food Intolerance Tests
There are various food intolerance tests, each with its own benefits and drawbacks. It’s important to choose the one that best suits your needs.

Elimination Diet: This involves removing potential allergens from your diet for a period of time and gradually reintroducing them. While effective, it can be difficult to stick to such a restrictive regimen.

Skin Prick Test: In this test, a needle with a small amount of a potential allergen is pricked into your skin. A reaction at the site of the prick can indicate an allergy or intolerance. It’s easy to perform and can detect both food allergies and intolerances.

Blood Test: This test measures IgG antibodies in your blood. Elevated levels of IgG antibodies suggest an intolerance to specific foods that your body mistakenly perceives as harmful.

Hydrogen Breath Test: This test measures the hydrogen gas in your breath after consuming certain carbohydrates. Elevated hydrogen levels can indicate an intolerance to specific carbohydrates.

Regardless of the test you choose, it’s essential to consult with a healthcare professional for accurate interpretation of the results. They can help you adjust your diet accordingly, manage symptoms, and improve your overall well-being.

Understanding Food Intolerance
Food intolerance occurs when the body has difficulty digesting certain foods, leading to uncomfortable symptoms like bloating, gas, and diarrhea. Though less severe than food allergies, food intolerance can still impact your quality of life.

Common types of food intolerance include:

Lactose Intolerance: Difficulty digesting lactose, a sugar found in dairy products, leading to bloating, cramps, and diarrhea.
Gluten Sensitivity: Causes discomfort after consuming gluten-containing foods, with symptoms like bloating, gas, and diarrhea.
Fructose Malabsorption: Difficulty digesting fructose, a sugar found in fruits and vegetables, causing digestive upset.
If you suspect food intolerance, consult with your doctor. Diagnostic tests can help identify the offending foods, making it easier to manage your symptoms. In addition, dietary supplements may alleviate symptoms—consult with a doctor or nutritionist to find the right options for you.

Why Take a Food Intolerance Test?

The Food Intolerance Test helps identify any potential allergies or sensitivities to a wide range of common foods. This includes everyday items like tea, coffee, cow’s milk, pork, eggs (both whites and yolks), almonds, wheat, gluten, and oats. It also tests for specific foods, such as beef, chicken, lamb, cod, salmon, shrimp, crab, casein, spelt, rye, rice, potatoes, various nuts (including hazelnut, peanut, and walnut), soy, mustard, and a variety of fruits and vegetables, including apples, oranges, strawberries, kiwis, peaches, bananas, tomatoes, carrots, celery, and onions. The test also checks for sensitivities to gluten, sesame, black pepper, baker’s yeast, and more. Taking this test provides valuable insights into which foods may be affecting your health, helping you make informed dietary choices.
