Although brain injury symptoms may subside enough for you to return to daily life, trauma to the brain can continue to subtly wreak havoc on how your body functions and feels for month and even years later. For instance, many people notice their hormone function isn’t the same after a brain injury.
Your hormonal command center — the hypothalamus and pituitary gland — is in the brain. Although a head injury may occur in an isolated area, the vast networks of communication across the entire brain mean that damage to one area affects the entire brain. And because the brain runs the body, it only makes sense daily operations of the body take a hit too.
Estimates on how many people suffer from hormone disorders caused by brain injury vary, however, one study of 1,000 patients with traumatic brain injury (TBI) found almost 30 percent had compromised pituitary function.
