High blood pressure, also known as hypertension, is classified as "essential'' (primary) or "secondary.” Essential hypertension does not have an apparent cause. It may be due to such things as family history or lifestyle. Most people with high blood pressure have essential hypertension.
Secondary hypertension, on the other hand, is less common and is the result of another condition, such as:
By starting a few new food habits, including counting calories and watching portion sizes, you may be able to lower your blood pressure and reduce the medications you need to control high blood pressure. Here's how.
Disorders of the adrenal gland (small organs, located above the kidneys, that create hormones), including Cushing's syndrome (a condition caused by an overproduction of cortisol); hyperaldosteronism (too much aldosterone); and pheochromocytoma (a rare tumor that causes oversecretion of hormones like adrenaline)
After you are diagnosed with hypertension, your doctor may perform other tests such as blood and urine screening to make sure you don't have secondary hypertension.
How Is Secondary Hypertension Treated?
In order to treat secondary hypertension, your doctor will address the condition or disorder that is causing the hypertension (adrenal gland disorder, kidney disease, sleep apnea, etc.) and try to correct that.
In cases where narrowed arteries are the cause of high blood pressure (coarctation, narrowed kidney arteries) surgery may be required to correct the problem. Not all patients will be eligible for surgery, however.
Your doctor may also choose to treat you with antihypertensive drug therapy, in addition to addressing the underlying health issues.
If you have secondary hypertension that is caused by a drug, your doctor may suggest that you stop taking or decrease the dose of the drug.
