Allergies and intolerances are two distinct types of adverse reactions that can occur when a person consumes or comes into contact with certain substances. Here's an overview of the differences between allergies and intolerances:
Allergy:
An allergy is an immune system response to a specific substance, known as an allergen. When a person with an allergy is exposed to the allergen, their immune system reacts abnormally, considering the substance as harmful and initiating an immune response. This immune response triggers the release of histamine and other chemicals in the body, leading to allergy symptoms. Common allergens include certain foods (e.g., peanuts, shellfish), pollen, dust mites, animal dander, insect venom, and certain medications.
Key features of allergies include:
1. Involvement of the immune system.
2. Immediate or delayed reaction after exposure to the allergen.
3. Symptoms can range from mild to severe and may include hives, itching, swelling, nasal congestion, sneezing, coughing, wheezing, difficulty breathing, gastrointestinal issues, and in severe cases, anaphylaxis.
Intolerance:
An intolerance refers to difficulty digesting or processing certain substances, typically due to a lack of specific enzymes or sensitivity to certain components in the substance. Unlike allergies, intolerances do not involve an immune system response. Intolerances can manifest in various ways and can be caused by different factors, such as enzyme deficiencies (e.g., lactose intolerance due to a lack of lactase enzyme) or sensitivity to food additives (e.g., sulfites, monosodium glutamate).
Key features of intolerances include:
1. Lack of immune system involvement.
2. Symptoms are typically related to the digestive system, such as bloating, gas, diarrhea, abdominal pain, or discomfort.
3. Symptoms may occur hours or days after consuming the offending substance, making it more challenging to identify the specific trigger.
It's important to note that intolerances, although not life-threatening like severe allergies, can still cause significant discomfort and impact an individual's quality of life. Allergies, particularly severe ones, can be life-threatening and require immediate medical attention.
If you suspect you have an allergy or intolerance, it's advisable to consult with a healthcare professional for an accurate diagnosis and appropriate management strategies. They can help determine the specific triggers, recommend tests if needed, and provide guidance on avoidance measures or treatment options to alleviate symptoms.

An allergy is an immune system reaction to a particular substance that is usually harmless, such as pollen or peanuts. Symptoms of an allergy can range from mild to severe and can include itching, swelling, hives, and difficulty breathing.
An intolerance is a reaction to a particular substance, usually food, that is caused by the body's inability to digest or process it. Symptoms of an intolerance can include abdominal pain, bloating, gas, and diarrhea.

ALLERGY: AN ALLERGY IS AN IMMUNE SYSTEM RESPONSE TRIGGERED BY EXPOSURE TO A SPECIFIC SUBSTANCE KNOWN AS ALLERGEN. WHEN A PERSON WITH AN ALLERGY COMES INTO CONTACT WITH AN ALLERGEN, THEIR IMMUNE SYSTEM RECOGNIZES IT AS ATHREAT AND PRODUCES AN ALLERGIC RESPONSE.
INTOLERANCE: FOOD INTOLERANCE ALSO REFERRED TO AS A NON- ALLERGIC FOOD HYPERSENSITIVITY IS A REACTION TO A PARTICULAR FOOD OR INGREDIENT THAT DOESN'T INVOLVE THE IMMUNE SYSTEM.
