What is the endocrine system?
Your endocrine system includes glands and organs that make and release hormones, which are chemicals that help your body work properly. They control growth, sexual development, how your body uses and stores energy (metabolism), how it deals with illness, and more. You need proper types and amounts of hormones to feel well.
Two important parts of the endocrine system—the pituitary gland and the hypothalamus—are located in or near the brain. TBI can injure them, causing hormone problems. A person with TBI may have hormone problems right away or months or even years after the injury.
