In a recent Scientific Statement issued by the Endocrine Society, researchers say that high blood pressure, also known as hypertension, affects one in four American adults.
In about 15% of these people, high blood pressure is caused by hormone, kidney or other disorders.
The rate can be as high as 50% among children and 30% among young adults.
Experts advises doctors spot hormonal causes of high blood pressure that can be cured with surgery or treated effectively with medication.
Without effective screening, common hormonal causes of high blood pressure, such as the disorder termed “primary aldosteronism”, often go undiagnosed and untreated.
This can leave people with these conditions at greater risk of developing heart disease, stroke, kidney disease, and even dying.
According to the researchers, high blood pressure can be the first sign of any of 15 endocrine disorders.
The endocrine system produces and controls hormones.
Hormones are chemical messengers that govern growth, reproduction, metabolism, breathing and other essential bodily functions.
Potential causes of high blood pressure can include tumors that produce adrenal hormones such as aldosterone and adrenaline, thyroid disorders, obstructive sleep apnea, or acromegaly, a rare condition where excess growth hormone builds up in the bloodstream.
The Scientific Statement delves into the number of people affected by the 15 endocrine disorders and the screening process for these disorders.
The most common endocrine cause of high blood pressure is primary aldosteronism.
Primary aldosteronism occurs when the adrenal glands produce too much of the hormone aldosterone. The glands are the small glands located on the top of each kidney.
This causes a build-up of aldosterone, which normally balances blood levels of sodium and potassium. The resulting excess sodium can raise blood pressure levels.
As many as one in 10 people with high blood pressure may have this condition, according to the researchers.
People with primary aldosteronism face an increased risk of cardiovascular problems, including death and stroke, compared to people who have similar blood pressure levels that are not caused by an underlying endocrine condition.
The researchers suggest that screening for underlying causes of high blood pressure can save lives.
This new resource offers healthcare providers valuable guidance on when to suspect a hormone disorder and how to test for it.
