Blood pressure is the force of blood pushing against the walls of the arteries as it circulates through the body. It is measured in two numbers: the top number, called systolic pressure, measures the force when the heart beats, while the bottom number, called diastolic pressure, measures the force when the heart is at rest between beats. Blood pressure is an important indicator of overall health and can be affected by various factors such as age, diet, exercise, stress, and medical conditions. It is important to maintain a healthy blood pressure level to prevent various health problems such as heart disease, stroke, and kidney disease._

Uncontrolled high blood pressure (hypertension) can lead to a range of serious complications that can affect various parts of the body. Some of the most common complications of uncontrolled high blood pressure include:

1. Heart disease: High blood pressure can lead to the buildup of plaque in the arteries, which can increase the risk of heart disease, heart attack, and heart failure.

2. Stroke: Uncontrolled high blood pressure can cause the arteries in the brain to narrow or burst, leading to a stroke.

3. Kidney damage: High blood pressure can damage the small blood vessels in the kidneys, leading to kidney failure or the need for dialysis.

4. Eye damage: Uncontrolled high blood pressure can cause damage to the blood vessels in the eyes, leading to vision loss or blindness.

5. Peripheral artery disease: High blood pressure can cause narrowing of the blood vessels in the legs and arms, leading to pain and numbness.

6. Aneurysm: Uncontrolled high blood pressure can cause the blood vessels to weaken and bulge, leading to the risk of aneurysm, which is a potentially life-threatening condition.

7. Cognitive decline: High blood pressure can damage the blood vessels in the brain, leading to cognitive decline and an increased risk of dementia.

It is important to monitor and manage blood pressure to prevent these complications and maintain overall health.
