What are hormones?

Hormones are chemical messengers produced by endocrine glands that regulate various activities and functions in the body.

They are released directly into the bloodstream and travel to target organs or tissues, where they control processes such as growth, metabolism, reproduction, mood, and development.

Examples of hormones include insulin, which regulates blood sugar levels, and sex hormones like testosterone and estrogen, which control changes during puberty.

Hormones are essential for maintaining coordination and balance among different body systems.

Even small changes in hormone levels can significantly affect body functions and overall health.
