1.0 Introduction
1.1 Background of Study
Hypertension, also known as high blood pressure, is a major public health issue and one of the leading causes of cardiovascular diseases worldwide. It is a chronic medical condition characterized by persistently elevated arterial blood pressure, which increases the risk of stroke, heart disease, and kidney failure (World Health Organization [WHO], 2023). The condition is particularly prevalent among elderly individuals due to age-related physiological changes, including arterial stiffness and reduced vascular elasticity (James et al., 2021). These changes contribute to the increased incidence and severity of hypertension in older adults.
The global burden of hypertension is alarming, with over one billion people affected, and the prevalence is significantly higher in elderly populations (Centers for Disease Control and Prevention [CDC], 2023). In many developing countries, including Nigeria, the prevalence of hypertension among the elderly is rising due to urbanization, sedentary lifestyles, and dietary changes (Okafor & Adeyemi, 2022). Unfortunately, awareness and control rates remain low, resulting in a high incidence of hypertension-related complications such as stroke, heart failure, and chronic kidney disease (Brown et al., 2022). Uncontrolled hypertension in elderly individuals presents unique challenges in management, as it often coexists with other chronic conditions such as diabetes, arthritis, and cognitive impairment (Smith & Johnson, 2020). Additionally, poor adherence to medication, limited healthcare access, and socio-economic factors contribute to poor hypertension control among this age group (Williams et al., 2022). While pharmacological treatments play a crucial role in blood pressure management, non-pharmacological interventions such as dietary modifications, physical activity, and stress management are equally important in reducing hypertension-related complications (American Heart Association [AHA], 2022).
Hypertension is a significant public health concern, especially among elderly individuals. Aging is associated with physiological changes that affect the elasticity of blood vessels, leading to increased blood pressure levels (James et al., 2021). The prevalence of hypertension among older adults is notably high, with studies indicating that over 60% of individuals aged 60 and above suffer from the condition (Centers for Disease Control and Prevention [CDC], 2023). The progressive nature of hypertension makes early detection, proper management, and adherence to treatment essential in preventing severe complications such as stroke, heart failure, and renal dysfunction (Smith & Johnson, 2020).
Hypertension, commonly known as high blood pressure, is a chronic medical condition characterized by persistently elevated blood pressure levels in the arteries. According to the World Health Organization (WHO, 2023), hypertension is defined as a systolic blood pressure (SBP) of 140 mmHg or higher and/or a diastolic blood pressure (DBP) of 90 mmHg or higher, based on multiple readings taken on different occasions. This condition increases the risk of cardiovascular diseases, kidney failure, and other serious health complications (American Heart Association [AHA], 2022). Therefore, this study seeks to explore the causes, complications, and management of hypertension among elderly individuals.
1.2 Statement of Problems
Investigation revealed that many elderly individuals are either unaware of their hypertensive status or do not receive proper medical attention until complications arise. Inadequate health education, limited access to healthcare services, and financial constraints make it difficult for many older adults to seek early diagnosis and consistent treatment (Brown et al., 2022). Even when treatment is available, adherence to antihypertensive medication is a challenge due to forgetfulness, lack of understanding of the condition, and concerns about medication side effects (Williams et al., 2022).
Furthermore, the impact of lifestyle factors such as poor diet, physical inactivity, stress, and excessive salt intake is another critical issue. Many elderly individuals struggle to adopt and maintain healthier lifestyles due to mobility limitations, cultural food preferences, and the absence of strong social support systems (James et al., 2021). As a result, non-pharmacological interventions that are known to be effective in managing hypertension are often underutilized.
In many developing countries, the burden of hypertension among the elderly is worsened by weak healthcare systems, inadequate funding for geriatric care, and a lack of trained medical personnel specializing in elderly health (Okafor & Adeyemi, 2022). The absence of structured hypertension screening programs means that many elderly individuals remain undiagnosed until they experience severe complications. The psychological impact of living with a chronic illness also contributes to poor management, as depression and anxiety often reduce the motivation to seek care and adhere to treatment (Anderson & Lee, 2022). It is against the backdrop that this study seeks to address these problems by identifying challenges in diagnosis, treatment, and prevention strategies to improve health outcomes and quality of life.
1.3 Aim and Objectives of Study

1.9 Definition of Terms
Hypertension:
Hypertension, commonly known as high blood pressure, is a medical condition characterized by consistently elevated blood pressure levels above 140/90 mmHg (World Health Organization [WHO], 2020). It is often referred to as the "silent killer" because it may not present noticeable symptoms but can lead to serious health complications such as heart disease, stroke, and kidney damage if left unmanaged.
Elderly People:
Elderly people, in the context of this study, refer to individuals who are aged 60 years and above (United Nations, 2019). The elderly population is particularly vulnerable to various health conditions, including hypertension, due to the physiological changes associated with aging, such as a decrease in the elasticity of blood vessels and an increase in vascular resistance.
Complications of Hypertension:
Hypertension-related complications refer to the severe health problems that arise as a result of uncontrolled high blood pressure. These include conditions such as stroke, heart failure, kidney disease, and cognitive decline (American Heart Association [AHA], 2020). These complications can significantly impair the quality of life and lead to disability or death, particularly among elderly individuals.
Management of Hypertension:
The management of hypertension involves various strategies aimed at controlling blood pressure levels and preventing complications. These may include lifestyle modifications (such as dietary changes, physical activity, and stress management), pharmacological treatments (such as antihypertensive medications), and regular monitoring by healthcare providers (National Institute for Health and Care Excellence [NICE], 2019).
Pharmacological Treatment:
Pharmacological treatment refers to the use of medications to manage hypertension. Common antihypertensive drugs include diuretics, beta-blockers, calcium channel blockers, and ACE inhibitors. These medications help reduce blood pressure by either relaxing blood vessels, reducing the heart's workload, or eliminating excess fluid from the body (Mayo Clinic, 2021).
Non-Pharmacological Treatment:
Non-pharmacological treatment includes lifestyle interventions that do not involve medications. These strategies focus on improving health through diet, physical activity, weight management, stress reduction, and reducing alcohol and tobacco consumption (American College of Cardiology [ACC], 2021).
