Generally when we talk about hypertension, 90% of the cases we are referring to Primary and Secondary hypertension. Primary Hypertension is the most common form of hypertension (almost 95% of the cases).
Primary or essential hypertension means that high blood pressure has been found while measuring on three or more consecutive checks, and there is no other cause behind it. Once the cause of this condition like kidney disease, thyroid problem, sleep apnea etc. is treated, blood pressure goes back to normal.
Secondary hypertension means that the blood pressure is elevated due to some other underlying condition like an abnormality in the arteries supplying blood to the kidneys, airway obstruction during sleep, diseases and tumors of the adrenal glands, hormone abnormalities, thyroid disease, and too much salt or alcohol in the diet.
