Hypertension is a common disorder of the circulatory system, affecting around one in seven adult Australians and becoming more common with age. Older people may experience a change in their blood pressure pattern due to their arteries becoming more rigid (less elastic). High blood pressure is a risk factor for many diseases such as heart attack, kidney failure and stroke. Generally Hypertension is not associated with any specific symptoms and regular measurement is the only way to monitor its control. Lifestyle modification is one of the best way to prevent and treat high blood pressure. Sometimes blood pressure control becomes difficult despite many medications called resistant hypertension. In such cases specialist care is required to assess, review and treat the condition.
