When a meal seems to trigger symptoms, it is tempting to order a long list of food tests. The useful first step is to understand what happens, when it happens and whether you might have a food allergy, an intolerance or a digestive condition. At RescueMD in Allen, we can review your history, discuss appropriate medical testing or referral, and help you build a nutrition plan without eliminating foods you do not need to avoid.
A food allergy involves the immune system and may cause hives, swelling, wheezing or other symptoms, sometimes rapidly after eating. If you have trouble breathing, throat swelling or signs of a severe reaction, seek emergency care. Suspected allergy should be assessed by an appropriate clinician; testing is chosen from the history, not a broad screening panel alone. An intolerance may cause digestive symptoms without an allergic mechanism. Lactose intolerance is one example. “Food sensitivity” is a broad everyday term, not a single medical diagnosis. Bloating or fatigue after eating can have many causes, so a careful history matters before any test is ordered.
Commercial IgG blood panels are often advertised as tests that identify foods causing inflammation or delayed sensitivity. Food-specific IgG may reflect exposure to a food; it has not been shown to diagnose a food allergy, intolerance or sensitivity. The American Academy of Allergy, Asthma & Immunology recommends against using IgG panels for this purpose. A long list of “positive” foods can lead to unnecessary restriction and nutritional gaps.
If you already have a panel, bring it to your appointment. We can review your symptoms and explain what the result can and cannot tell you. We do not use an IgG score alone to label foods unsafe.
The answer depends on your symptoms. A clinician may consider a targeted allergy evaluation for reactions suggesting an immediate allergy, tests for celiac disease when the history fits, or other medical assessment for persistent gastrointestinal symptoms. If celiac disease is a possibility, ask about testing before starting a gluten-free diet, since removing gluten can affect test results. Some people benefit from a structured symptom and food record or a short, supervised elimination and reintroduction trial. A registered dietitian can help make that process specific and nutritionally adequate. No single test or elimination plan is right for every person.
Your visit may include a review of symptom timing, usual foods, medications and relevant diagnoses. We will discuss whether testing, a referral or a guided nutrition change makes sense. If you need help with ongoing bloating or IBS symptoms, our gut health dietitian program may be a better fit. For broader nutrition support, see our registered dietitian services .
Our office is at 945 Stockton Drive, Suite 6100, Allen, TX 75013. Patients from Allen, Frisco, Plano and McKinney can visit for an assessment. Ask about the availability of a virtual nutrition visit where you live.
No. We start with your history and recommend only an assessment that fits the clinical question. Broad IgG panels are not recommended to diagnose food sensitivity.
If you think a food causes a severe allergic reaction, avoid it and seek appropriate medical guidance promptly. Otherwise, ask a clinician before starting an extensive elimination diet. If celiac testing is being considered, do not start a gluten-free diet without discussing how that may affect the test.
Yes. A dietitian can help you look for patterns, test reasonable dietary changes and keep your meals balanced while your medical team evaluates persistent symptoms.
