Primary hypertension occurs when the blood pressure in your arteries is too high. This makes your heart work harder to pump blood through your body. High blood pressure rarely causes symptoms, but the damage it does to your arteries can be severe. Left untreated, it can lead to heart attack, kidney failure, and stroke. Unchecked high blood pressure can also damage your vision and memory. It is associated with erectile dysfunction.
Primary hypertension can be treated by your primary care doctors with lifestyle changes including smoking cessation, diet, exercise, and antihypertensive medications. However, you may be referred to a high blood pressure specialist if resistant or secondary hypertension is present.
Resistant hypertension occurs when three or more antihypertensive medications fail to bring your high blood pressure under control. People more likely to experience resistant hypertension include:
- African Americans
- People with obesity

- Overuse of salt and alcohol
