Take Charge of Your Medical Conditions

If you have high cholesterol, high blood pressure, or diabetes, you can take steps to lower your risk for heart disease.

Your health care team should test your blood levels of cholesterol at least once every 4 to 6 years. If you have already been diagnosed with high cholesterol or have a family history of the condition, you may need to have your cholesterol checked more often. Talk with your health care team about this simple blood test. If you have high cholesterol, medicines and lifestyle changes can help reduce your risk for heart disease.

High blood pressure usually has no symptoms, so have it checked on a regular basis. Your health care team should measure your blood pressure at least once every 2 years if you have never had high blood pressure or other risk factors for heart disease.

If you have been diagnosed with high blood pressure, also called hypertension, your health care team will measure your blood pressure more often to make sure you have the condition under control. Talk with your health care team about how often you should check your blood pressure. You can check it at a doctor’s office, at a pharmacy, or at home.

If you have high blood pressure, your health care team might recommend some changes in your lifestyle, such as lowering the sodium in your diet; your doctor may also prescribe medicine to help lower your blood pressure.

If you have diabetes, monitor your blood sugar levels carefully. Talk with your health care team about treatment options. Your doctor may recommend certain lifestyle changes to help keep your blood sugar under control. These actions will help reduce your risk for heart disease.

If you take medicine to treat high blood cholesterol, high blood pressure, or diabetes, follow your doctor’s instructions carefully. Always ask questions if you don’t understand something. Never stop taking your medicine without first talking to your doctor, nurse, or pharmacist.

You and your health care team can work together to prevent or treat the medical conditions that lead to heart disease. Discuss your treatment plan regularly, and bring a list of questions to your appointments. Talk with your health care team about how heart disease and mental health disorders are related.

If you’ve already had a heart attack, your health care team will work with you to prevent another one. Your treatment plan may include medicines or surgery and lifestyle changes to reduce your risk. Be sure to take your medicines as directed and follow your doctor’s instructions.
