Charisse Timbol Gumapas, ARNP, with The Everett Clinic discusses Asthma. Asthma is a chronic illness that affects the airways. It is treated and managed with inhalers - a daily controller medication and a rescue medication. Keeping your home clean and reducing dust and pet hair can reduce symptoms in your child - daily vacuuming and keeping covers on mattresses and pillows reduces exposure to dust mites. Properly controlling your child's asthma allows them to play and be kids!
