The causes of Hypertension are unknown in 95% of patients. In 5% of cases, some specific conditions can be responsible for the high blood pressure, such as kidney disease, atherosclerosis and hormonal imbalance. There are also several risk factors that may increase your chances of developing hypertension including diabetes, obesity as well as a strong family history of the disease.
It is important to understand that the blood pressure varies throughout the day depending on what you are doing. For example, if you are exercising, feeling stressed, or in pain, your blood pressure will increase temporarily for the duration of the condition. In these instances, you do not require any medical attention; treatment is only needed if your blood pressure is constantly raised.
