What is a Food Intolerance Test?


Have you ever felt bloated, tired, or just not quite right after eating, but had no clue why? That uncomfortable, silent struggle can make mealtimes stressful and confusing. This is where understanding meets relief with a Food Intolerance Test.

Food intolerance symptoms often hide beneath the surface; they do not shout, but quietly disrupt your well-being. It is frustrating when beloved foods become hidden triggers, and guessing won’t unlock the answers your body needs.

At Sun Diagnostics, we guide people across Navi Mumbai, from busy professionals to caring families, to listen to their bodies with confidence. Our accurate and timely food intolerance tests provide the clarity you need to work with your doctor and make informed choices for a healthier, happier life.

What is Food Intolerance and How is it Different from Food Allergy

That stomach twist after a favourite meal isn’t always about overeating-it might trace back to how your body processes food. Understanding food sensitivities begins with recognising the body’s unique responses that don’t always involve the immune system.

Defining Food Intolerance

Food intolerance occurs when the digestive system reacts poorly to certain ingredients, primarily due to an inability to process or break them down properly.

Symptoms such as bloating, cramps, or headaches may appear hours later, creating confusion about the actual cause. These issues typically don’t cause emergencies but affect your day-to-day comfort.

Food Intolerance vs Food Allergy

Unlike a food allergy, which triggers the immune system and can be severe or life-threatening, food intolerance does not cause an immediate immune reaction. Allergy tests check for IgE antibodies, which are often used to detect sensitivities to nuts, shellfish, or eggs. Meanwhile, food intolerance tests explore delayed responses, usually through IgG testing.

Common Causes of Food Intolerances

A lack of digestive enzymes, such as lactase, can cause intolerance. Some react to chemicals like amines in cheese or additives like MSG and artificial colourings. These reactions can creep in subtly and build up over time, causing daily discomfort.

Signs and Health Effects of Food Intolerance

Sometimes, recurring discomfort is more than a coincidence. Recognising food intolerance symptoms is the first step in finding lasting relief.

Digestive Issues

Bloating, gas, stomach pain, and irregular bowel movements often point towards unwanted food triggers. These symptoms fluctuate with diet and aren’t tied to busy schedules or stress, although they can feel similar.

Skin and Respiratory Reactions

Flares of acne, eczema patches, or rashes may link to poorly tolerated foods. Even mild respiratory issues, such as nasal congestion, may be linked to something in your diet.

Unexplained Fatigue and Mood Changes

Feeling mentally foggy or unusually tired after meals could be your body responding to something it dislikes. Some report mood swings or irritability linked to certain food ingredients.

Impact on Long-term Health

Continued exposure to tolerated foods can trigger ongoing inflammation. Over time, this affects nutrient absorption, skin clarity, weight, and general wellness.

Types of Food Intolerance Tests

Testing helps shift health from guesswork to clarity-whether you prefer lab work or self-assessment from home.

IgG Blood Tests

These tests measure IgG antibodies in response to foods. At Sun Diagnostics, we utilize advanced machines to capture even the most subtle reactions, with a quick turnaround and expert review by Dr. Nikhil.

Elimination Diets

This method involves removing foods for approximately two weeks and then reintroducing them one at a time. It suits those wanting insight without lab tests but requires close tracking and consistency.

At-home Testing Kits

Test kits delivered to your doorstep help you collect samples and send them to a lab. While convenient, some may not be as accurate as direct lab-based testing at centres like ours in Navi Mumbai.

Genetic and Advanced Diagnostic Tools

We offer DNA tests and MRT testing that dive deeper into genes and pathways. These options are best suited for individuals with ongoing issues or those whose past tests have been inconclusive.

Specific Food Intolerance Categories

Knowing which food causes trouble lets you live more freely. At Sun Diagnostics, we test for the top culprits with precision and accuracy.

Gluten Sensitivity and Celiac-related Testing

Testing can help determine if symptoms are caused by gluten intolerance or the autoimmune disease called Celiac Disease. We help you decode symptoms using detailed gluten and wheat protein panels.

Dairy-related Intolerances

We check for lactose and casein sensitivity through blood and breath tests. Symptoms like bloating or gassy discomfort often clear up when dairy triggers are removed.

Other Frequently Intolerant Foods

We identify issues related to soy, nuts, eggs, and wheat. These aren’t just allergens, but also familiar sources of intolerance. Pinpointing them reduces recurring discomfort, especially in mixed or processed meals.

Why Take a Food Intolerance Test

If eating right feels like walking a tightrope, a food intolerance test helps you step with confidence.

Persistent Unexplained Symptoms

Tests help explain headaches, digestive troubles or tiredness. We even offer food intolerance quizzes to support early recognition and guide necessary testing.

Personalized Health Management

Your test results create a personal guide for smart eating. Our specialists work with you to shape meal choices that keep you energised and comfortable.

Prevention and Long-term Wellness

Identifying problem foods early prevents more significant issues later. Regular testing prevents future nutritional gaps, skin challenges, and energy dips.

Physician Recommendations

Dr. Nikhil Ningurkar, with over a decade of expertise, advocates intolerance testing to protect digestive and immune well-being. Our certified team interprets test panels using scientific precision.

Using Test Results for Better Living

Every result holds answers to questions your body has been asking for months, maybe even years.

Creating a Tailored Diet

We help build food lists that avoid your triggers. You’ll know what to switch out and what to enjoy without second-guessing your plate.

Improving Energy, Mood and Concentration

Feeling clear-headed and active again often begins with removing one small item from your diet. Food has the absolute power to influence how the body and mind function.

Supporting Weight Management and Skin Health

Undiagnosed food issues secretly affect metabolism or skin clarity. Our testing clears the fog, putting weight and glow back under your control.

Regular Monitoring and Follow-ups

We guide you through re-tests and check-ins if symptoms return or patterns shift. Your body changes-so testing does too.

Interpreting and Understanding Test Results

Knowing your results means knowing your next step, rather than guessing through trial and error.

Reading IgG Test Panels

We explain each IgG response in simple terms. If wheat, milk, or tomato shows a high reaction, that food likely contributes to your symptom patterns.

Consulting Healthcare Professionals

Dr. Nikhil Ningurkar and our diagnostic centre team provide detailed consultations post-testing. This bridges your results with real lifestyle action, not just data on paper.

Avoiding Common Misconceptions

Intolerance tests don’t replace allergy tests. Gluten sensitivity isn’t the same as an allergy, and IgG isn’t about danger-it’s about patterns and digestion clues.

Your Body’s Been Whispering It Is Time to Listen


Our bodies often send gentle signals through discomfort or fatigue that we may overlook. These subtle messages are important and deserve attention. Listening carefully to your body can help you understand its needs and take steps toward better health.

Food is not just fuel. It is an experience to be savoured and honoured. As the saying goes, “Eat to live, do not live to eat.” Taking the time to enjoy each bite allows your body to absorb nutrients more effectively and helps you connect with what feels right for you.

At Sun Diagnostics, we offer food intolerance tests that provide clear insights into how your body reacts to various foods. By paying attention to these signs and choosing your meals mindfully, you can create a healthier and more joyful relationship with food.

Trust your body’s wisdom and begin the journey to wellness today.
