Hormones are the body’s chemical messengers and are part of the endocrine system. Endocrine glands make hormones, which travel through the bloodstream to tissues and organs, and control most of our body’s major systems. The endocrine system regulates our heart rate, metabolism – how the body gets energy from the foods we eat – appetite, mood, sexual function, reproduction, growth and development, sleep cycles, and more.


  • Hormones play a critical role in our body’s chemistry, carrying messages between cells and organs.
  • Hormones affect our body’s functions, from growth and sexual development and mood to how well we sleep, how we manage stress and how our body breaks down food.
  • When they are in proper balance, hormones help the body thrive. But sometimes hormone levels are too high or too low. Hormone imbalances can occur any time regardless of one’s age and cause serious health problems requiring ongoing medical management.

If you have concerns about any of your hormones, talk to an endocrinologist. To find an endocrinologist in your area, search our online directory today.
