What causes high blood pressure?
Blood pushing vessel walls is measured with blood pressure. The blood is transported throughout the body by the heart's pumping of blood into the arteries (blood vessels). High blood pressure, commonly known as hypertension, is risky because it makes the heart work harder to pump blood throughout the body and causes atherosclerosis, or the hardening of the arteries, those lead to heart failure.
How Much Blood Pressure Is "Normal"?
Systolic and diastolic readings of blood pressure have top and bottom numbers, respectively. Ranges include:
Prehypertension: 120-139 over 80-89
Stage First high BP: 140-159 over 90-99
Stage Second high BP: 160 and above over 100 and above
People whose blood pressure is above the normal range should consult their doctor about steps to take to lower it.
What Causes High Blood Pressure?
Although the precise causes of high blood pressure are unknown, a number of disorders and variables, such as the following, may contribute to its occurrence:
Being overweight or obese
Lack of physical activity
Too much salt in the diet
Too much alcohol consumption (more than 1 to 2 drinks per day)
Stress
Older age
Genetics
Family history of high blood pressure
Chronic kidney disease
Adrenal and thyroid disorders
Essential Hypertension
Up to 95% of reported high blood pressure cases in the U.S. lack a known underlying cause. This form of hypertension is known as essential hypertension.
Certain risk factors have been linked to essential hypertension, despite the fact that it is still mainly unknown. High blood pressure is more common in males than in women, and it usually runs in families. Race and age are further factors. Black Americans are twice as likely as White Americans to have high blood pressure, while the difference starts to close around the age of 44. Black women experience the highest frequency of high blood pressure after the age of 65.
Essential hypertension is also significantly influenced by dietary and lifestyle decisions.
High blood pressure and salt consumption are related
The inhabitants of Japan's northern islands, where salt consumption is highest per capita, are those with the highest prevalence of essential hypertension. People who don't salt their food, in comparison, exhibit almost no signs of essential hypertension.
Most persons with high blood pressure are "salt sensitive," which means that anything that exceeds their body's basic requirement for salt causes their blood pressure to rise.Stress, insufficient potassium, calcium, and magnesium intake, a lack of physical activity, and chronic alcohol use can all raise the chance of developing essential hypertension in addition to obesity, diabetes, and other conditions.
Secondary Hypertension
When a direct cause of high blood pressure can be identified, the disorder is referred to as secondary hypertension. Kidney illness is the most common cause of secondary hypertension. Additionally, tumors and other abnormalities that cause the small glands that sit on top of the kidneys, the adrenal glands, to emit excessive amounts of the hormones that raise blood pressure can result in hypertension. Blood pressure can be raised by pregnancy, blood pressure-raising medications, and birth control pills, particularly those containing estrogen.
