Food intolerance (food sensitivity) happens when an individual is having difficulty digesting a particular food. It can lead to intestinal gas, diarrhea or abdominal pain. The initial symptoms are frequently slow and delayed for hours of digestion after eaten the food, and the symptoms might last for hours, till the next day, sometimes a lot longer.
It is usually difficult to know if it is because of illness, and which food is responsible. When it comes to food tolerance, some persons can handle a particular quality of the food and get symptoms when the food is taken in excessively. The symptoms of food intolerance differ, but include nausea, joint pain, night sweats, fatigue, diarrhea, and other serious conditions.
When a particular food is suspected, the condition should be diagnosed, evaluated and treated by a medical professional that is qualified, such as a certified allergist. Some testing methods are not proven and are considered controversial. Some may trigger an allergic reaction. The allergist may have to conduct tests to diagnose a food allergy, and these tests can’t provide clear-cut answers. It will be combined with your medical history to provide the right diagnosis.
- Skin Prick Test
During this test, the allergist uses a solution that contains food and drops it on your forearm or back. The food solution will include fruits, vegetable or fresh food, using a probe or needle. The allergist scratches or pricks the skin gently to allow a small amount of the food solution go below the skin surface. The skin prick test is not painful, and you will not bleed. However, you will feel a prick like a fingernail is scratching you. Although 50-60 percent of skin prick test results show false positive results, in the hands of an allergist with experience it can be extremely helpful.
- Oral Food Challenge
Over the course of the food challenge, the allergist gives you the food suspected inconsistent doses. It typically begins with small amounts that might not result in symptoms. The allergist keeps you on observation for some time to see if you have any reactions. If there are no reactions, the dosage will be increased. If you still do not react, the challenge will be discontinued. With this procedure the reactions are mostly mild. Severe reactions are not common. You will be given some medication to help with relieving the symptoms. If there are no symptoms, the intolerance will be ruled out. The allergist will provide food avoidance methods and medications if the test establishes that you have the food intolerance.
- Elimination Diet
This diet lasts for two to four weeks. During this period, you will not take in the suspected food. The allergist will monitor your symptoms and introduce the food to your diet from time to time. The elimination diet must be done under the guidance of a certified allergist.
