Primary hypertension is also known as ‘essential hypertension’ and occurs slowly and gradually as the time proceeds. There are several causes that result in hypertension. These causes are characterized into three headings:-
Some people are genetically susceptible to hypertension. They may inherit the defective or mutated genes from their ancestors. A study suggested that only 2 to 3% of the people suffer from hypertension due to their defective genes.
Sometimes, even a small body malfunction in a day can trigger high blood pressure.
Today, environmental factors account largely for high blood pressure. People are adapting to the changing environment and this has led them to suffer from severe disease and conditions, hypertension being the most common and chronic condition of them.
Some environmental factors associated with hypertension are improper diet, lack of exercise, stress, weight problems, etc.
Secondary hypertension is the condition in which a person suffers from high blood pressure due to some serious health conditions such as kidney disease (chronic kidney disease), thyroid problem (such as hyperthyroidism), congenital heart complications, medicinal side effects, tumors, etc.

Children age 3 and older should generally have their blood pressure measured as a part of their routine checkups every year.
