Hormones & Hypertension

What is hypertension?

Hypertension, or high blood pressure, is a main cause of cardiovascular disease, which may lead to death. Hypertension really raises your risk of heart attack, stroke or kidney failure. Since people with hypertension often have no symptoms, it has been called "the silent killer."

As blood flows through the body, it pushes against the walls ,of the arteries that carry it. This force in the arteries is the blood pressure. The measurement of blood pressure includes systolic and diastolic readings. An example 120/80 mm Hg. The first umber is the systolic pressure as he heart contracts. The second umber is the diastolic pressure when the heart relaxes between contractions.

Hypertension is a rise in blood pressure above the normal level. Normal blood pressure is below 20/80 mm Hg. If your systolic blood pressure is 120 to 139 mm Ig or your diastolic blood pressure is 80 to 89 mm Hg, you are prehypertensive." If your blood pressure is always at least 140/90 mm Hg, you have hypertension.

What causes hypertension?

There are two types of hyper¬tension-primary and secondary. Most hypertension is the primary type. Its cause is unknown, but genetics and things such as high salt intake, obesity, tobacco, and alcohol have a part. Hormones made in the kidney and in blood vessels play a key role in the start and maintenance of primary hypertension.

Secondary hypertension occurs with another disease, such as kidney disease, and certain hormonal disorders such as Cushing's syndrome. Use of steroid hormones to treat a different medical problem is another cause of secondary hypertension.

How is hypertension treated?

Although there is no cure for primary hypertension, more than 80 medications are available to reduce blood pressure. Doctors often prescribe medication and lifestyle changes.

Depending on its cause, surgery or medications that affect specific hormones in the body can cure secondary hypertension.

What should you do with this information?

If your doctor diagnoses hypertension, you cm control it with medication and lifestyle changes.

After a hypertension diagnosis, you should have regular blood pressure checks to see how well your treatment is working. The goal is to lower your systolic blood pressure to under 140 mm Hg and to lower your diastolic blood pressure to under 90 mm Hg. If you have diabetes or kidney disease, the goal is to lower your blood pressure to under 130/80 mm Hg.

Recommendations for Lifestyle Changes

•  Keep a healthy weight (body mass index of 18.5 to 24.9).

Reduce the amount of saturated and total fat in your diet. Eat lots of fruits and vegetables, ---and choose low-fat dairy products.

Reduce salt in your diet.

Exercise (e.g., brisk walking) at least 30 minutes a day, most days of the week.
