> An allergist is a doctor who diagnoses and treats allergies and asthma. They find out what triggers your reactions and plan how to manage them.

## When people see one

- Hay fever or sinus symptoms that medicine does not control
- A reaction to food, an insect sting, or a medicine
- Asthma that keeps flaring up
- Hives or eczema with no clear cause

## How it differs

- Ear, nose and throat doctor (ENT): An ENT treats the ears, nose, and throat, including some allergy-related sinus problems. An allergist tests for triggers and treats the immune reaction behind them.

## On 2027 Colorado plans
