If high blood pressure is caused by some other disease or health condition, like kidney disease or pregnancy, it's called secondary high blood pressure. Sometimes blood pressure returns to normal when the other condition is treated.
Treating the condition that has caused your secondary high blood pressure will not always lower your blood pressure back to a normal level. In this case, you may need to treat the high blood pressure itself.
Your doctor may decide to treat both if it will take a long time to cure the other condition or if your blood pressure is dangerously high. If it takes too long to cure the other condition, the high blood pressure will have more time to damage your system.
If treating the other condition will put you at high risk for serious problems, your doctor may choose to treat your high blood pressure only.
