Hypertension

hypertension cardiovascular_disease blood_pressure chronic_disease
Hypertension, also known as high blood pressure, is a chronic medical condition where the blood pressure in the arteries is persistently elevated. It is a major risk factor for cardiovascular diseases and can lead to severe health complications if left untreated.

Introduction to Hypertension

Hypertension, commonly referred to as high blood pressure, is a condition characterized by consistently elevated pressure of blood against the arterial walls. This condition can lead to serious health problems, such as heart disease, stroke, and kidney failure.

Causes and Risk Factors

Hypertension can result from various factors, including genetics, lifestyle, and underlying health conditions. Common risk factors include obesity, a high-salt diet, lack of physical activity, excessive alcohol consumption, and stress. Additionally, conditions such as diabetes and chronic kidney disease can contribute to the development of hypertension.

Symptoms and Diagnosis

Often called the 'silent killer', hypertension may not present clear symptoms in its early stages. When symptoms do occur, they may include headaches, shortness of breath, or nosebleeds. Diagnosis is typically made through regular monitoring of blood pressure using a sphygmomanometer.

Treatment and Management

Treatment for hypertension often involves lifestyle modifications such as a healthy diet, regular physical activity, weight loss, and reducing salt intake. Medications, such as diuretics, ACE inhibitors, and beta-blockers, may also be prescribed to help control blood pressure.

Complications

Uncontrolled hypertension can lead to severe complications, including heart attack, stroke, heart failure, and kidney damage. Therefore, early detection and management are crucial to prevent these outcomes.

Context from Referenced By
Chronic Kidney Disease

Chronic kidney disease (CKD) can contribute to the development of hypertension by causing an imbalance in fluid and electrolytes, leading to increased blood volume. Additionally, the kidneys may produce more renin, a hormone that regulates blood pressure, further increasing hypertension risk. Effective management of CKD is essential to mitigate the risk of developing hypertension.
