Causes of secondary high blood pressure include: 1  Kidney disease, such as narrowing of the kidney arteries. 2  Certain medicines, such as birth control pills, amphetamines, appetite suppressants, some antidepressants, steroids, and some nonsteroidal anti-inflammatory drugs (NSAIDs).f a health problem is the cause, this high blood pressure may return to normal when the other health problem is treated.
