I'm a 35 yr old female i have high blood pressure my doctor says its from my adrenal gland not shutting down how serious is this?

Serious enough.: This is fairly important to deal with. If it is from your adrenal gland, you might need endocrine tests/see endocrinologist to ascertain the cause. It might be due to a pituitary hormone/chemical causing the adrenal to overproduce whatever hormone causing your high bp. See your doctor to discuss it more and try to get to an endocrinologist to find out.

Hypertension: The cause of your high blood pressure can be due to a few hormonal/chemical imbalances that would warrant further discussion with your doctor to better understand what may be the cause. This may necessitate medical or surgical therapy depending on the cause.
