Food Allergies Symptoms
2 AnswersThe symptoms of a dairy allergy are widespread. People with this allergy typically have gas, bloating, abdominal pain, and diarrhea. Food allergies cause widespread inflammation and may cause malabsorption, leading to iron deficiency anemia, osteoporosis and other diseases.

No. The symptoms develop within minutes or up to 2 hours after a person has eaten food that contains the allergen. If you experience similar symptoms over 2 hours later, see your doctor to rule out other possibilities.
The only exception is that a breastfed baby may develop symptoms between 2 and 8 hours after mom has ingested the allergen.

2 AnswersMs. Vandana R. Sheth , Nutrition & Dietetics, answered on behalf of Academy of Nutrition and DieteticsTeenagers typically do not want to seem different from their peers. This is a stage when socialization and friendships have a profound effect. A teenager with food allergies needs to be vigilant about their food allergies while continuing to enjoy life as a teenager. Parents need to be supportive while reminding their teens about "safe" food choices. A registered dietitian specializing in food allergies can be a valuable team member who can support and provide teens with tips to handle various social situations while maintaining food allergy safety.
1 AnswerDr. Christopher M. Webber, MD , Allergy & Immunology, answered on behalf of Sky Ridge Medical CenterFood allergy and intolerance symptoms differ. The symptoms of a food allergy tend to be relatively predictable, and include the following:
- Hives/welts: These skin reactions happen in about 90 percent of patients with an allergy. Hives tend to be itchy welts with individual lesions lasting more than 24 hours, although the total rash itself might come and go over more than a day. If you break out in a rash, take pictures to show your healthcare professional.
- Swelling (angioedema): There may also be swelling of the mouth, face, hands, feet or groin area.
- You may experience abdominal pain, nausea, vomiting or loose stools.
- You might get lightheaded, or feel dizzy or about to pass out.
- Anaphylaxis: Allergic reactions also carry with them the risk of death.
- Rash: not a hive rash, but a red rash that may or may not be itchy and tends to last for more than 24 hours.
- There is rarely swelling.
- There is often abdominal pain, nausea, possibly vomiting, constipation or loose stools. This is a very common symptom with food intolerance.
- Headaches sometimes happen. But feeling lightheaded, dizzy or passing out is very unusual for a food intolerance.
- You may feel fatigued or have decreased energy.
- Weight gain or weight loss is not a usual symptom of intolerance although it can happen. It is always important to search for more common causes of weight changes if this is the only problem.

It causes symptoms like bloating, cramping, fatigue, diarrhea and general gastrointestinal issues; it can even predispose you to liver disease or cancer.

While there are many tests out there to test for allergies, an elimination diet, when done correctly, is the one of the best ways to identify the culprit of a food allergy or intolerance. This diet is done by eliminating possible trigger foods, particularly the foods that are typically allergens including: Wheat and gluten, dairy, eggs, nuts, fish, shellfish and soy. A person should plan to stay on a complete elimination diet, avoiding all possible trigger foods, for about 4 days. After that initial elimination, trigger foods will be eaten one at a time, including one particular trigger food 3 times during a day, unless, of course, a reaction occurs!
During this diet, a food diary should be kept where all foods that are eaten are recorded and any side effects or reactions are noted. After introducing a food, the individual should plan to go back on the complete elimination diet for 2-3 more days, continuing to record foods and negative reactions in a food diary. One will continue this process of introducing possible trigger foods until the food causing the allergy or intolerance is identified. It is important that this diet is monitored by a Registered Dietitian or physician to ensure the proper balance of nutrients are being provided during the elimination period.
