The most common cause for high blood pressure is something called , essential hypertension. This means that there is no clear correctable cause and the doctor can procede with medical treatment.
Rare correctable causes of hypertension
One of the correctable causes include a tumor in the adrenal gland producing an excess of a hormone called aldosterone ( Conns Disease). A tip off to diagnosing this disease is high blood pressure associated with an unexplained low blood potassium level. Potassium levels are included in most routine chem. screens.
Another rare adrenal gland tumor is pheochromcytoma. This tumor is difficult to diagnose and may cause periodic episodes of high or low blood pressure , excessive sweating , fast heart rate and anxiety.
Renal artery stenosis -
A narrowing or obstruction of arterial blood flow to one kidney can cause hypertension.
Most doctors will go through their medical careers with out ever seeing a patient with one of the above problems.
