What Are Food Allergies?
Food allergies are reactions that happen when your body thinks certain foods are harmful. In fact, your immune system tries to fight these foods, even though they are usually safe for most people. Because of this, you may notice symptoms soon after eating the food. Food allergy symptoms can range from mild to severe. According to the CDC, food allergies affect millions of people worldwide. For many, managing food allergies is a daily part of life.
Most Common Food Allergens
Some foods are more likely to cause allergies than others. These foods are called common allergens. For example, the following foods cause most allergic reactions:PeanutsTree nuts (such as almonds, walnuts, cashews)MilkEggsFishShellfish (like shrimp, crab, lobster)SoyWheat
Even a small amount of these foods can trigger a reaction in some people. Therefore, it is important to know which foods you need to avoid.
Symptoms and Signs of Food Allergies
Food allergy symptoms can appear within minutes or up to two hours after eating. However, some people may notice signs even later. Common symptoms include:Itchy skin or hivesSwelling of lips, face, or throatStomach pain, nausea, or vomitingDiarrheaWheezing or trouble breathingDizziness or fainting
Sometimes, a severe reaction called anaphylaxis can happen. This is a medical emergency and needs quick treatment. If you notice trouble breathing or swelling in the throat, call for help right away.
How Food Allergies Affect Overall Health and Daily Life
Living with food allergies can change your daily routine. For instance, you may need to read food labels carefully. Eating out can also be risky. Because of the risk of severe reactions, some people feel anxious about trying new foods. Over time, food allergies can affect your nutrition if you avoid many foods. However, with good planning, you can still eat a healthy diet. Support from family and friends also makes a big difference.
Diagnosis: How Food Allergies Are Identified
If you think you have a food allergy, see a doctor. Usually, your doctor will ask about your symptoms and medical history. Next, they may suggest tests such as:Skin prick test: A small amount of food is placed on your skin to see if a reaction occurs.Blood test: This checks for allergy-related antibodies in your blood.Food challenge: You eat small amounts of the food under medical supervision.
Because these tests can have risks, they should only be done by a trained healthcare provider.
Emergency Management and Treatment Options
Quick action is important during a severe allergic reaction. For mild symptoms, antihistamines may help. However, if you have trouble breathing, swelling, or feel faint, use an epinephrine auto-injector if you have one. Then, call emergency services right away. Always carry your emergency medicine if you have a known food allergy. In addition, let friends and family know what to do in an emergency. Emergency treatment for food allergies can save lives.
