Introduction: The prevalence of hypertension (HTN) in Saudi Arabia is witnessing an ascending trend since 1992. Hypertension (HTN) is a primary global health concern in ageing . Moreover, according to the 2020 Global Burden of Disease, hypertension accounted for roughly a quarter of cardiovascular disease fatalities and 1.9 percent of all deaths in Saudi Arabia in 2012. High blood pressure (hypertension) continues to be a global health problem. It was responsible for a yearly 10.2 million deaths and 208 million years of modified life for disability. In 2021, the Saudi Minister of health MOH declared that out of five elderly Patients in the middle east four are suffering from hypertension. However, earlier Saudi studies showed that hypertension (HTN) prevalence among elderly was around 49%. This high prevalence of hypertension in elderly would be associated with an increase in hypertension in adult. Also, hypertension is a significant risk factor for cardiovascular disease, morbidity, and mortality especially for the elderly. However, assessing blood pressure (BP) and preventing hypertension among elderly has become a global priority. Education is one way that can be used to increase one's knowledge and awareness education can be given in various fields, including health, the important of this study was to knowledge the effect of health education on increasing the knowledge and awareness of elderly people with hypertension in Saudi Arabia.
