  • Food Allergies: These can be lifelong and triggered by specific foods.

2. Severity of Allergy: How long do allergies last?

  • Mild Reactions: These might just cause mild symptoms like sneezing, itchy eyes, or a runny nose, and can last a few hours to a few days.
  • Severe Reactions: Anaphylaxis is a severe, life-threatening allergic reaction that can last for hours and require immediate medical attention.

3. Treatment:

  • Antihistamines and other medications: These can help reduce allergy symptoms and shorten their duration.
  • Immunotherapy: This type of treatment can help desensitize your body to allergens over time, reducing symptoms and even potentially eliminating allergies.

4. Individual Factors:

  • Age: Allergies can develop or change over a person's lifetime.
  • Overall Health: People with weakened immune systems might experience longer or more severe allergy symptoms.
  • Environmental Exposure: Exposure to allergens can trigger or worsen allergies.

In short, allergy duration can range from a few hours to a lifetime.
