Overview.
High blood pressure is a prevalent circumstance in which the force of blood on the walls of your arteries is often too high.
Arteries are the blood vessels that carry blood away from your heart to supply your tissues with oxygen and nutrients.
In your heart, two chambers, called ventricles, contract with each heartbeat to push blood to your lungs and through your arteries to your body.
Factors affecting blood pressure:
As blood flows through them, three main factors affect the pressure on your artery walls.
The first is cardiac output or the amount of blood your ventricles push out of your heart each minute. Your blood pressure goes up as cardiac output increases.
The second factor affecting your blood pressure is blood volume or the total amount of blood in your body. Blood pressure also goes up as blood volume increases.
The third factor that affects your blood pressure is resistance, which is anything working against the blood flow through your arteries.
Several factors contribute to resistance:
One resistance factor is the flexibility of your artery wall. Healthy arteries expand with each heartbeat to help reduce blood pressure on the wall.
Another resistance factor is the diameter of your arteries. Your body is able to increase the diameter of your arteries to lower your blood pressure or reduce the diameter to raise your blood pressure.
A third resistance factor is blood viscosity or thickness. In your blood, more particles, such as proteins and fat, increase viscosity. If your blood is thicker, your blood pressure goes up as your heart works harder to push it through your arteries.
Your blood pressure can be measured with a device called a sphygmomanometer, or blood pressure cuff. When your heart beats, the pressure of blood on the walls of your arteries is called systolic pressure.
When your heart relaxes between beats, pressure on the artery wall is called diastolic pressure. While your blood pressure may change throughout the day, it should normally be less than 120 millimeters of mercury for systolic pressure, and less than 80 millimeters of mercury for diastolic pressure.
If your systolic pressure frequently stays above 140, or your diastolic pressure frequently stays above 90, you have high blood pressure.
Over time, high blood pressure will damage the walls of your arteries. Your artery wall may become weak and form an enlargement called an aneurysm. Or the wall may burst and bleed into the surrounding tissue.
Small tears in your artery wall may attract certain substances in your blood, such as cholesterol, fat, and calcium, to form a build-up called a plaque. Blood flow through your artery decreases as the plaque enlarges.
Blood cells can stick to the plaque and form solid clumps, called clots, further reducing, or completely blocking, your blood flow.
Damage to your arteries raises your blood pressure even more by making your heart beat more forcefully. Artery damage and reduced blood flow lead to conditions such as: a stroke, heart attack, or kidney disease.
In most cases, the cause of high blood pressure, or hypertension, is unknown. This type of high blood pressure is called primary, or essential, hypertension.

Treatment.
Treatment for essential hypertension includes lifestyle changes, such as eating a healthy diet.
If you are sensitive to the sodium in salt, your doctor may recommend limiting your intake of salt and highly processed foods.
Sodium may cause your body to retain water, which increases both your blood volume and your blood pressure.
Other lifestyle changes that can reduce blood pressure include:
- Avoiding Excessive Alcohol Intake
- Getting Regular Exercise
- Losing Weight
- Quit smoking
High blood pressure medicine.
Your doctor may also recommend medications that act on your kidneys, blood vessels, or heart to help reduce your blood pressure.
Diuretics commonly called water pills, cause your kidneys to move more salt and water from your blood into your urine, which reduces your blood volume and pressure.
Beta-blockers reduce the workload on your heart by decreasing both the rate of your heartbeat and the strength of your heart’s contractions.
Several types of drugs act directly or indirectly to reduce your blood pressure by relaxing your blood vessels, which increases their diameter.
These drugs include ACE inhibitors, angiotensin II receptor blockers, calcium channel blockers, and direct-acting vasodilators.
Remedies for high blood pressure.
Foods to lower blood pressure immediately.
Garlic

Garlic offers blood pressure lowering benefits. It helps relax blood vessels by stimulating the production of nitric oxide. Which in turn lowers blood pressure especially systolic blood pressure.
Ingredients
Garlic Cloves
Water 4 tablespoons
Method
Take few garlic cloves and crush them and extract its juice by placing it on the sieve and pressing it with a spoon.
Then take five to six drops of garlic juice and add this to water.
Stir it well and drink this to get relief from the high blood pressure.
For more effective results drink this for twice a day till you get complete relief from the high levels of blood pressure.
Lemon

Lemon a popular citrus fruit, can help regulate high blood pressure. Its antioxidant vitamin C helps neutralize the harmful effects of free radicals. This, in turn, helps lower high blood pressure, reduces high cholesterol and improves overall heart health.
In addition, lemons are high in potassium that helps lower blood pressure by reducing the effects of sodium. According to a 2014 study published in the Journal of nutrition and metabolism. Regular lemon ingestion and walking have systolic blood pressure lowering effects.
Method
Mix juice of 1/2 a lemon to a cup of warm water.
Drink it on an empty stomach every morning.
Do not add salt or sugar to it for the best results.
Tomatoes

Method
Eat a cup of fresh tomatoes, tomato sauce, or blended tomato juice, every day.
If you do not like the taste of tomatoes, try taking lycopene supplements.
Avoid commercial tomato sauce which contains high levels of sodium.
Coconut water

Method
Drink 8 ounces of coconut water, one to two times daily to lower the high blood pressure.
Fenugreek seeds

Boil two teaspoons of fenugreek seeds in water for about two minutes.
Strain the water and make a fine paste.
Consume this paste on an empty stomach twice a day to obtain significant results.
