“Health workers: All people primarily engaged in activities intended to improve health.” — World Health Organization.

This definition reflects the broader role of healthcare professionals in supporting health and delivering coordinated care.

<h3>When Should You See a Doctor?</h3>

A medical evaluation may be appropriate when symptoms persist, worsen, or have no clear explanation. Regular healthcare visits can also support preventive care and the ongoing management of existing conditions.

A primary care doctor can provide an initial assessment and determine whether diagnostic testing, treatment, or specialist evaluation is appropriate.

Sudden or severe symptoms may require prompt medical attention.

Doctors provide essential healthcare through clinical assessment, diagnosis, treatment, prevention, and patient education. Because medical specialties differ in their areas of expertise, understanding the role of each type of doctor can help readers make more informed decisions about seeking appropriate healthcare.
