How the blood pressure works?
What are systolic and diastolic blood pressure and what are their symptoms?How many types of blood pressure are there? What are hypertension and hypotension? In this article, hypertension, normotension and hypotension were explained simply and informatively. We encourage you to continue using USFREEHEALTHCARE. Everyone needs blood pressure (BP) to survive. High blood pressure is a silent killer. Therefore, you must be aware of it and calmly fight this danger.
How does the heart pump blood?
To know your blood pressure, hypertension, hypotension, and normotension, you first need to know your heart.
The heart is made up of four chambers, two atria and two ventricles. Blood that has been oxygenated by the body's tissues returns to the right side of the heart through venous circulation. This blood is pumped into the right ventricle and then into the lungs where carbon dioxide is released and oxygenation takes place again. The oxygenated blood then returns to the left side of the heart, enters the left atrium, and from there flows into the left ventricle. The place from which blood is directed into the aorta and arteries.
heart:
slow pump
The heart is a fist-sized muscle that pumps blood 365 days a year. The human heart keeps pumping blood rich in oxygen and nutrients throughout the body.
blood vessel
veins and arteries:
Veins are a network of soft, flexible tubes that surround muscles and nerve vessels. Arteries are blood vessels that carry fresh blood from the heart to the body. Veins carry dirty blood from the body back to the lungs. Blood that has lost oxygen and nutrients from the upper and lower body returns to the right heart chamber through the veins.
The heart pumps used blood to the lungs through the pulmonary artery. The lungs absorb fresh oxygen from the air we breathe and release it into the blood. When you exhale, carbon dioxide is released from your lungs. Fresh, oxygenated blood returns from the lungs to the left ventricle of the heart. In this way, blood circulates throughout the body through the aorta and other veins. Arteries carry oxygen-carrying blood to the heart (coronary arteries). This is how the heart is supplied with the blood and energy it needs.
Blood pressure is the pressure that blood exerts on the walls of arteries. When you measure your bp you get two numbers like 80/120. The first number is the systolic pressure and the second number is the diastolic pressure. The numbers above indicate and measure the pumping and resting phases of the heart.
Systolic blood pressure (maximum)
The first number indicates the strength of the heart and the stage of the blood pump. A normal healthy systolic blood pressure is below 120 mmHg.
Diastolic blood pressure (minimum)
The second number indicates the resting (beat-to-beat) blood pressure. Healthy, normal diastolic bp is below 80 mmHg. Diastolic bp almost always stays the same, while systolic bp changes frequently. The body's response to daily activity and physical and psychological stress causes frequent changes in systolic bp. For example, if normal bp is 120/80 mmHg, stress can change it to 160/80 mmHg during work. Bp increases from 110/80 mm Hg to 150/80 mm Hg during the game.
What is high blood pressure?
High blood pressure puts undue strain on your arteries and heart. High bp is also called hypertension. Untreated and managed high bp can lead to serious health problems. These problems include heart failure, blindness, stroke, and kidney disease.
High blood pressure is very common, especially among older people. About 1 in 4 people suffer from high bp. Among younger patients, it is more common in men, but more common in women than in older men. In general, risk increases with age.
Blood pressure rises naturally with stress and physical activity, but people with high bp have higher than normal resting bp.
Blood pressure is her one of the most important signs of life. As large arteries lose their elasticity and natural strength and smaller vessels become narrower, bp rises. High bp is sometimes called the silent killer because symptoms often do not appear until later in life.
Causes of high blood pressure
Although the causes of high bp are not yet fully understood, several factors predispose to high bp, including:
After the age of 60, the likelihood of developing high bp increases with age.
Obesity and overweight;
smoking;
alcohol consumption;
A diet high in salt and saturated fat and avoiding fruits and vegetables.
inactivity and insufficient physical activity;
Emphasis;
Genetic factors, if one or both parents have high bp, the risk of developing high bp increases.
Taking birth control pills, steroids, and some types of appetite suppressants.
sit at the table.
Race:
Caucasians and Indo-Europeans are more likely to have high bp.
high blood pressure symptoms
Hypertension, or hypertension, is a chronic condition that usually presents with multiple symptoms and is sometimes asymptomatic. Commonly rare symptoms include dizziness, headaches, and nosebleeds.
People diagnosed with high blood pressure should have their blood pressure checked regularly.
The most common symptoms of high bp are:
headache;
nausea;
throw out;
dizzy;
blurred vision or double vision;
palpitations or a strong, irregular heartbeat;
difficulty breathing;
Symptoms of hypertension in children:
headache;
Malaise;
blurred vision;
nosebleed;
Bell's palsy, or inability to control muscles on one side of the face;
Symptoms of high blood pressure in babies and young children:
failure to thrive;
convulsions;
hypersensitivity;
faint;
respiratory disorders;
When should I see a doctor for high blood pressure?
If you notice any of the above symptoms, be sure to see your doctor. The above symptoms may be symptoms of another problem or negative side effects of medications. In this case, it may be necessary to prescribe another drug with fewer side effects.
Note:
Once hypertension is noticed, bp should be constantly monitored and treated. Bp may return to normal, but this is extremely rare. Medications and lifestyle changes should be continued to stabilize blood pressure.
What is normal blood pressure?
Normal blood pressure for all humans should be 120/80. So the major or systolic pressure is 120mmHg and the minor or diastolic pressure is 80mmHg.
Some people who suffer from low blood pressure all the time sometimes faint with lethargy and need to be taken to the hospital to recover with serum injections. There may be no particular reason for low bp in these people. No, hypotension means systolic blood pressure less than 90 mm Hg. But when the mercury drops below 80 mm, problems arise. People with low bp are usually young, very thin women whose bodies are accustomed to this condition, but certain circumstances can cause the pressure drop to be greater than before.
Low blood pressure is a symptom. Symptoms include weakness, dizziness, red eyes, severe lethargy with sometimes loss of consciousness, and, in the final stages, a complication called syncope. Of course, excessive bleeding can also cause bp to drop. Examples include internal bleeding from accidents, gunshot wounds, and clotting disorders.
This type of bleeding is very dangerous and can quickly lead to low blood volume, low bp, and even death. Some disorders, such as diarrhea and vomiting, also cause dehydration, low blood volume, and low bp. For this reason, prompt fluid exchange in patients is always recommended, and patients with diarrhea or vomiting should increase their fluid intake. Of course, some cardiovascular and pulmonary diseases also lead to low bp.
Causes of low blood pressure
One cause of low blood pressure is excessive blood loss from the body, and other causes of low bp can be serious, life-threatening infections or allergic reactions.
Medical conditions that can lead to low blood pressure include:
pregnancy:
Blood pressure tends to drop during pregnancy because the circulatory system dilates rapidly. This is normal and bp usually returns to pre-pregnancy levels after delivery.
heart problems:
Heart conditions that can lead to low blood pressure include a very slow heart rate (bradycardia), heart valve problems, heart attack, and heart failure.
Endocrine issues:
Thyroid disease, such as parathyroid disease, adrenal insufficiency (Addison's disease), hypoglycemia (hypoglycemia), and possibly diabetes, can increase the likelihood of low bp.
dehydration:
One cause of low bp is dehydration, which can lead to weakness, dizziness and fatigue. Fever, vomiting, severe diarrhea, overuse of diuretics, and strenuous exercise can lead to dehydration.
Severe infection:
Another cause of low bp is a severe infection (sepsis). When an infection in the body enters the bloodstream, it can cause a dangerous drop in bp called septic shock.
Blood loss is another cause of low bp, including serious injuries and internal bleeding that reduce the amount of blood in the body and cause a sudden drop in bp.
A severe allergic reaction (anaphylaxis) is also a cause of low bp. Food, certain drugs, and insect bites are common causes of this serious and potentially life-threatening reaction. Anaphylaxis can cause trouble breathing, itching, a sore throat, and a dangerous drop in bp.
Nutrient deficiencies in the diet, such as vitamin B-12 and folic acid deficiencies, can also contribute to low blood pressure. Taking some drugs can also cause low bp.
When should I see a doctor?
If your blood pressure is persistently low and you don't have any of the above symptoms, it's usually nothing to worry about. It is normal for bp to rise over time, and the body can usually bring it back to normal. If your bp drops suddenly and you experience symptoms such as dizziness, be sure to see a doctor to diagnose the factors and causes of your low bp.
