What are food intolerances?

Food intolerance is characterized by difficulty in digesting particular foods. Food contains proteins, vitamins, carbohydrates, fats, and natural chemicals that add to its flavor and smell. Some of these can trigger symptoms of food intolerance. Food intolerance differs from a food allergy, where even a small amount of allergic food can cause a mild to severe immune response. Food intolerance usually develops gradually and may occur when you consume too much of a particular food, too often. To learn more about food intolerances and how they can affect your GI tract, contact GI Alliance to speak to a skilled gastroenterologist.

What are the symptoms and causes of food intolerances?

A number of symptoms may result from food intolerances. Some of the most common include:

  • Fatigue
  • Dark circles under the eyes
  • Joint pain
  • Night sweats
  • Diarrhea
  • Vomiting
  • Bloating
  • An irritable bowel
  • Skin-related symptoms (such as rashes and eczema)

Food intolerance is specific to you and is caused by foods that are normally safe for a majority of others. Among the most common causes are:

  • Lack of enzymes specific for the breakdown of certain foods
  • Certain naturally occurring chemicals such as caffeine
  • Some foods such as kidney beans or chickpeas that have a toxic effect when undercooked
  • Food containing histamines (such as fish that has been stored poorly)
  • Salicylates in certain fruits, vegetables, herbs, and spices
  • Wide variety of artificial additives, preservatives, and coloring agents used in processed foods

How are food intolerances treated?

The pattern and type of symptoms help to distinguish food intolerance and differentiates it from allergic reactions. Keeping an accurate record of your food intake and resulting symptoms helps to identify the foods that may cause these reactions. Once the triggering food is determined, you are advised to temporarily eliminate it from your diet under controlled conditions. Our GI Alliance gastroenterologists will then observe you for improvement or relief from symptoms. Following this, the trigger is reintroduced into your diet to confirm the diagnosis. This is carried out under the supervision of a dietitian who will substitute the eliminated food with similar food, ensuring that nutrition is maintained.

Dr. Russo has been with our daughter since leaving the NICU 2 years ago and I cannot say enough how much we appreciated his professionalism and medical expertise. Every visit he was so welcoming and very gentle with our little girl. Thank you so much for being her primary GI specialist so glad we’ve finally graduated from the visits and will recommend your name to everyone.

Dr. Volak took such excellent care of my extremely sick mom before she passed that I decided to make him my GI doc as well. He found the issues my mom had when others could not. He has consideration for his patients and listens without judgement or preconceived notions. As a disabled person with numerous health issues and specialists myself, I feel confident and safe in his care. Love him, would recommend to anyone who wants excellent care. 😉 We're all deserving of that!
