Food Allergies & Intolerances
Newport Beach Gastroenterologist – (949) 645-8300
Many people living with food allergies and intolerances only have a general idea of what foods actually trigger an allergic reaction. Others know what foods to avoid and think they will live their whole life without ever enjoying them. Advancements in gastroenterology and immunology are changing food allergies and intolerances for the better, though.
Come to Richard Quist, MD, FACG, FASGE, Medical Corporation, Inc. and speak with our team in Newport Beach. Gastroenterologist Richard Quist and Registered Dietician Madeline Said can diagnose your allergy with accuracy to give a better understanding of its triggers and dangers. We may also be able to help you reduce the severity of future allergic reactions through a directed diet that addresses specific gastrointestinal (GI) diseases.

What Causes a Food Allergy or Intolerance?
Every patient’s food allergy or intolerance is unique to them in terms of triggers and severity. Our team is here to diagnose and study your food allergy to get to its cause.
- A food allergy or intolerance can be caused by:
- Certain GI diseases
- Sensitivity specific substances in specific foods
- Incorrect immune system response to some chemicals
- Imbalance of digestive enzymes
When the cause of your food allergy is known, we can get to work looking for a solution that works best for you. The goal of our Newport Beach gastroenterologist is giving you the tools needed to confidently avoid trigger foods, or even build a tolerance to them overtime to reduce the severity of an allergic reaction.
Directed Diets & Other Fixes
One of the best approaches to food allergy and intolerance mitigation is a directed diet. Doctors Quist and Said may instruct you to remove certain foods from your diet for several weeks and record your digestive health during that same amount of time. This process of elimination can pinpoint which foods are causing an intolerant reaction in your digestive tract.
- Dietary diets are particularly helpful if a patient has been diagnosed with:
- Irritable bowel syndrome (IBS)
- Gastroesophageal reflux disease (GERD)
- Acid reflux disease
- Unclear or undefined food allergies
Our Newport Beach gastroenterological clinic can also suggest blood tests if it is suspected that your food allergy is related to celiac disease, lactose intolerance, or another autoimmune system complication. We may also suggest an endoscopy to view your digestive tract with a small, flexible camera to check for signs of some GI diseases.
