Can A Gastroenterologist Diagnose Food Allergies

Naturopathic Doctor Or Nutritionist

Food Allergies-Mayo Clinic

If you are convinced you are reacting to gluten even though your tests are negative, you might have a subset of gluten allergy that doesn’t fit neatly into either category of celiac disease or wheat allergy. The Gluten Intolerance Group of North America differentiates gluten intolerance/sensitivity from celiac disease as experiencing distress when eating gluten-containing products and showing improvement when following a gluten-free diet while having negative blood and biopsy testing. A naturopathic doctor or nutritionist is trained extensively in nutrition and identifying food intolerance through the use of an elimination diet or specialized testing.

A Final Word About A Gluten Free Diet

A gluten free diet can present a challenge in regards to whole grain intake since it eliminates some of the most common sources of whole grain, including wheat, rye and barley. Fortunately, it can also provide an opportunity to eat a more whole food diet as is evidenced by the list above. While there are many refined gluten-free grain replacements such as cornstarch, potato starch, tapioca starch and white rice flour, the variety of nutritious gluten free whole grains is plentiful. So, rather than having the gluten free diet be a challenge, look at is as an opportunity to increase both variety and nutrient content through the incorporation of the above mentioned gluten free foods, including whole grains.

Id like to leave you with two gluten free recipes to try that will help incorporate the whole grains listed above.

When To See A Doctor

You should see your doctor if you have any of the symptoms above when you eat foods containing gluten. This can be a sign of gluten intolerance or another serious problem like celiac disease or wheat allergy.

If you work with a doctor or registered dietician nutritionist to remove gluten from your diet but you still have symptoms or your symptoms get worse, you might have a condition other than gluten intolerance. If this happens, you should talk to your doctor or RDN, because you might need to change your diet or have additional testing done.

Food Allergy And Food Intolerance

Many products and internet sites promise a miracle cure for food allergy or food intolerance but many of their claims are not based on any solid evidence.

The best thing to do if you think you have a food allergy or are intolerant to foods such as dairy or wheat, is to see a specialist who uses evidence.

Consultant Gastroenterologist Ana Wilson offers expert food allergy testing, diagnosis and professional advice and treatment.

Gut Barrier And Oral Intolerance

Food Allergy or Food Intolerance

Food allergy represents an abnormal response of the mucosal immune system to antigens delivered through the oral route. The gastrointestinal mucosal barrier is a complex physical and immunologic structure. Despite the complex mucosal barrier, about 2% of ingested food antigens are absorbed and transported throughout the normal mature gut wall., Even though intact foreign food antigens routinely penetrate the gastrointestinal tract, they infrequently induce clinical symptoms because of the development of oral tolerance to dietary proteins in most individuals. Recent studies suggested that antigen-presenting cells, especially intestinal epithelial cells and dendritic cells, and regulatory T cells play a central role in oral tolerance., However, the underlying immunologic mechanisms involved in oral tolerance induction are not fully understood.

A large epidemiologic study has identified infectious gastroenteritis as the most significant environmental risk factor for the development of IBS, suggesting that previous infection and persistent low-grade inflammation may play an important role in the pathogenesis of functional gut diseases. This may be because of impairment of the complex immune response of the gastrointestinal mucosa, which results in a breakdown of oral tolerance.

When To Try Home Treatment

You can treat your symptoms at home when you have hives over a small area of your body that aren’t associated with other allergy symptoms .

Many people assume that food allergies are the only cause of hives, but hives can be caused by many triggersâheat, cold, stress, medications, infections, and exercise are others.

Mild cases of hives that don’t cover much of the body and don’t appear with other symptoms of a severe reaction can be treated with over-the-counter antihistamines such as Benadryl to reduce itching and swelling.

Nonetheless, if your hives do not respond to several doses of antihistamine, cause severe discomfort, or if they appear every time you eat a particular food, they warrant a call to your healthcare provider.

Managing Childrens Food Allergies

There are many steps you and your child can take to help manage your childs food allergies. A successful management plan may include:

  • Read food labels carefully to avoid the allergen
  • Informing all caretakers of the allergy
  • Wearing a medical alert I.D.
  • Having medication available at all times
  • Taking medication as soon as a reaction occurs

You should discuss developing an emergency plan for you and your child with your doctor.

Where Do I Start

This was my biggest question and the one that caused me the most angst. Once I got started though, it became easier and almost second nature to cook within the parameters of these new food omissions. So, for starters, lets focus on gluten first. Over the next few months, I plan to post more on food allergies and intolerances, specifically gluten and dairy, so please stay tuned.

Allergies On Your Food Plate? | FYI

90% of all reactions to food in children occur from these eight common allergens, but could be allergic to any number of foods:

  • Milk
  • Wheat
  • Peanut
  • Tree Nuts almonds, Brazil nuts, cashews, pecans, pistachios, pine nuts, chestnuts, filberts/hazelnuts, macadamia nuts, and walnuts
  • Fish
  • Shellfish shrimp, crab, crawfish, crawdad, crayfish, lobster and prawns

    Should I See A Gastroenterologist For Ibs

    Gastroenterologists are not the best at treating IBS since they are specialists in life threatening digestive conditions. For serious symptoms like severe abdominal pain, bloody diarrhea, or severe watery diarrhea, you should see a gastroenterologist in order to rule out other problems.

    Once that has happened the gastroenterologist may diagnose you with IBS and may provide you with some type of treatment. If that is not successful in curing your IBS, then you should see an IBS specialist.

    How Is Food Intolerance Managed

    The first step is expert medical assessment to make sure there is no underlying medical condition, e.g. inflammation or structural problem with the digestive tract. Once a positive diagnosis has been made, dietary exclusion is usually the next step, although some physicians will use medications to reduce histamine release.

    Involvement of a dietician can be very helpful to identify foods which trigger symptoms. Recently, its become clear that many food intolerances involve complex carbohydrates, which can be managed with a low FODMAP diet. FODMAP stands for fructose, oligo-, di- and monosaccharides and polyols. Reducing these can be effective in about 70% of cases. Overall, a structured diet is usually effective at reducing symptoms.

    The Approach Of A Gastroenterologist

    Inflammatory symptoms, immune system and food intolerance ...

    Gastroenterology is primarily a specialty in assessing the structure of the digestive tract. Gastroenterologists are experts in evaluating how the digestive tract looks and in very specific diseases of the digestive tract, not syndromes or symptoms that can only be described by the patient but not seen by the doctor.

    Gastroenterologists primarily focus on the visual inspection of the digestive tract, like performing colonoscopies and upper endoscopies. They also do other imaging work of the GI tract, such as an ultrasound, CT scan, MRI, x-rays, and even pill cameras.

    They may also perform studies that assess the motility of the digestive tract. Therefore, if you go to a gastroenterologist, your diagnosis will be based on these types of testing.

    Gastroenterologists are focused on diagnosing ulcers, polyps, cancers, and other physically and visually apparent abnormalities of the digestive tract. This is a very important specialty, and their significance cannot be overstated. However, this does not mean that they are experts in everything related to digestion.

    Gastroenterologists have no special training in immunology even though the digestive tract is the single most concentrated area of immune activity in the body, nor do they have any special training in diet or nutrition, or most types of reactions to foods. They also do not have any special training in the use of different types of probiotics, different types of enzymes, or the treatment of deficiencies of stomach acid.

    Food Intolerance Or Food Allergy

    Food intolerances are very common. In fact, many people often confuse food intolerance with food allergies. However, they are different.

    Food allergy

    A legitimate food allergy causes an immune system response, which affects several organs within the body. These reactions can vary from moderate symptoms, like developing hives or a body rash, to life-threatening symptoms, such as anaphylaxis, which causes your immune system to release a flood of chemicals that can cause you to go into shock.

    Other symptoms of food allergies include:

    • Tingling of tongue, lips or face
    • Swelling of hands, feet, mouth or tongue
    • Rapid pulse or arrhythmia
    • Wheezing or trouble breathing
    • Blurred vision

    If you are experiencing any of the above symptoms, you should speak to your primary health care provider or seek emergency care if needed.

    Food intolerance

    In contrast, food intolerances typically have less serious symptoms and are more commonly related to the gastrointestinal tract. The most common food intolerances are lactose intolerance and food additive intolerances, such as monosodium glutamate or flavor enhancers.

    Food intolerances with digestive tract symptoms include but are not limited to:

    • Abdominal bloating
    • Vomiting
    • Abdominal pain or cramping

    Food intolerance does not cause bloody or black stools, fainting, abnormal heart rates, muscle weakness or seizures. If you are experiencing any of these symptoms, you should speak to your primary health care provider.

    Adverse Food Reaction Is Not Always An Allergy

    Many types of adverse food reactions are often confused with food allergies. Allergists consider a true food allergy to be an abnormal response of the immune system to food protein.

    These abnormal responses are mediated by immunoglobulin E antibodies or by immune cells .

    The IgE-mediated food allergies are the kind that may result in immediate hives and swelling or anaphylaxis, a potentially life-threatening reaction with multiple symptoms. Common food allergies in children include allergies to egg, milk, peanut, tree nuts, fish, shellfish, soy and wheat however, children can develop an allergy to almost any food.

    Symptoms develop typically within 30 minutes, but can occur up to two hours after ingestion, and may include hives, lip and/or eye swelling, mouth itching, throat discomfort, coughing, wheezing, difficulty breathing, vomiting, diarrhea and a drop in blood pressure, which may be lead to dizziness or fainting. These symptoms are the result of chemicals, such as histamine, which are released in the body when IgE binds to a particular food protein.

    Non-IgE-mediated food allergies typically cause gastrointestinal symptoms. These symptoms may include repetitive vomiting, chronic diarrhea, blood in the stool, weight loss or difficulty swallowing. These gastrointestinal food allergies are often diagnosed either by history alone or with endoscopy by a gastroenterologist.

    Prevalence Of Food Hypersensitivity And Allergy In Ibs

    Although the prevalence of perceived adverse food reactions is high, with up to 20% of the general population reporting skin allergy, asthma, intestinal symptoms, headaches, and behavioral changes related to foods, the actual prevalence of true food hypersensitivity or intolerance is estimated to be 5% in the general population.- The prevalence of food hypersensitivities is greatest in the first few years of life, affecting about 6% of infants less than 3 years of age in the United States, but decreases with age. The perception of food hypersensitivity in IBS seems to be higher than in the general population, with 2065% of IBS patients attributing their symptoms to food hypersensitivity. ,, In fact, patients with IBS often report that specific foods aggravate their symptoms. However, there are discrepancies between perceived food hypersensitivity or food intolerance and actual food allergies in patients with IBS. Dainese and colleagues reported that more than 50% of IBS patients were found sensitized to some food or inhalant by skin prick test without any typical clinical signs, but patients were unable to identify potentially offending foods.

    Diagnosing Food Allergies And Food Intolerances

    Knowing whether you have an allergy or intolerance is important because food allergies are potentially life-threatening. People with food allergies should carry emergency lifesaving medications, such as epinephrine in an injectable form.

    The diagnosis of a food allergy is made based on a history of a reaction to a food and a positive skin or blood test that confirms the allergy.

    For example, if you eat shrimp and you develop hives on your skin and swelling of your lips immediately afterwards, there is a strong clinical suspicion for shrimp allergy, so we would confirm this diagnosis with allergy testing by skin prick method or by blood test, Dr. Sheikh says.

    A positive skin or blood test alone, without symptoms suggestive of an allergic reaction, means your body may be sensitized but not necessarily that youre allergic.

    Food intolerance is sometimes difficult to diagnose because theres no accurate, validated test to identify food intolerance.

    A good way to identify if a food is causing intolerance is to keep a food diary to track and recognize what regularly eaten food may be causing an adverse reaction, Dr. Sheikh says.

    Symptoms associated with a food intolerance that we worry about and say see a doctor as soon as possible would be sudden weight loss, blood in the stool, throwing up blood and having food stick when you swallow, Dr. Dellon says. Those could indicate a more serious condition.

    Treatment Of Food Allergies In Children

    Treating a food allergy may involve avoiding the foods that contain the allergen causing the reaction. Unfortunately, there is currently not a cure for food allergies.

    Milder symptoms may be treated using:

    • Antihistamines
    • Inhalers
    • Injectors

    You should speak with your childs doctor about the best treatment methods for the child.

    Things You Can Do To Prepare For Allergy Testing

    Signs and Symptoms of Anaphylaxis

    The best thing to do before going in for food allergy testing is to relax. The process is simple, and once its done you can rest easier knowing that youre on the path to eliminating annoying or dangerous symptoms associated with eating certain foods.

    You can also ask your gastroenterologist or nurse practitioner to write you a prescription for a numbing cream.

    Applying the cream to your back before testing can help to reduce the amount of itching you feel from being exposed to the antigens. It also reduces how much you feel the prick of the applicator points, though most people dont find them too painful.
