What does it mean to have hbp at the age og 20?

It means: That your blood pressure is high and that you should immediately listen to the advice of your doctor regarding lifestyle and dietary changes, exercise, lose weight if necessary, stop smoking and if drugs are involved, stop using. If medications are recommended in the interim until you can successfully make the other changes then follow that advice as well. This will help avoid future complication.

HBP: Higher salt intake and excess body weight may lead to higher blood pressure. Hypertension in younger individuals may be related to secondary causes such as hormonal or vascular conditions. This should be evaluated by your physician. Regardless of cause, high blood pressure should be treated appropriately.
