Blood pressure - Animation

The force of blood on artery walls is called blood pressure. Normal pressure is important for the proper flow of blood from the heart to the body's organs and tissues. Each heart beat forces blood to the rest of the body. Near the heart, pressure is higher, and away from it lower. Blood pressure depends on many things, including how much blood the heart is pumping and the diameter of the arteries the blood is moving through. Generally, the more blood that's pumped and the narrower the artery the higher the pressure is. Blood pressure is measured both as the heart contracts, which is called systole, and as it relaxes, which is called diastole. Systolic blood pressure is measured when the heart ventricles contract. Diastolic blood pressure is measured when the heart ventricles relax. A systolic pressure of 115 millimeters of mercury is considered normal, as is a diastolic pressure of 70. Commonly, this pressure would be stated as 115 over 70. Stressful situations can temporarily cause blood pressure to rise. If a person has a consistent blood pressure reading of 140 over 90, he would be evaluated for high blood pressure. Left untreated, high blood pressure can damage important organs, such as the brain and kidneys, as well as lead to a stroke.

Carrying a lot of extra weight around your middle or sprinkling too much salt onto your food at each meal can cause high blood pressure, otherwise known as hypertension. Stress and your genes can also bring your blood pressure up. Sometimes when your blood pressure is high, your doctor might not be able to find any direct cause for it. That's what's called essential hypertension. When your doctor talks to you about your blood pressure, he's referring to the force of your blood pushing against your artery walls. The top number in your blood pressure is called the systolic blood pressure. That's the pressure in your blood vessels while your heart is pumping. The bottom number is called the diastolic blood pressure and that's the pressure when your heart rests between beats. You want your blood pressure to stay at 120 over 80 or less. A blood pressure of 140 over 90 or more is considered high. Why is high blood pressure a problem, you ask? Well, you can think of high blood pressure as being like a river that's rushing too hard, eventually it's going to damage its banks. With high blood pressure, the extra force of your blood pushing against your artery walls eventually damages them. It can also damage your heart, your kidneys, and other organs. So, how do you know if you have high blood pressure?Often you don't know, because high blood pressure doesn't have symptoms like a fever or cough. Usually there are no symptoms at all, and you won't be able to find out that you have high blood pressure unless you've had it checked, or you've developed complications like heart disease or kidney problems. You can check your blood pressure yourself with a home monitor, or have it checked at your doctor's office. If it's high, you and your doctor will set a blood pressure goal. You can achieve that goal in different ways, like eating a healthy diet, exercising for at least 30 minutes a day, quitting smoking, eating less than 1,500 milligrams of salt per day, and using programs like meditation and yoga to relieve your stress. But if these lifestyle changes aren't enough, your health care provider might prescribe one or more medicines to lower your blood pressure. The reason why doctors are so serious about a patients' blood pressure is that having uncontrolled blood pressure can cause a lot of serious health problems, including heart attack, stroke, kidney disease, and loss of vision. When it comes to your blood pressure, it's best to be proactive. Call your doctor for a check-up if you haven't had one in a while, and get your blood pressure checked. If it's high, follow your doctor's advice for bringing it back into a healthy range.

If your doctor told you that you have high blood pressure, you may have wondered, what's the big deal? Well high blood pressure IS a big deal, because it can lead to a heart attack, stroke, vision loss, and kidney disease, sometimes before you even realize you have it. When you have high blood pressure, you'll want to control it before it can lead to these dangerous complications. Let's talk about high blood pressure, otherwise known as hypertension. Blood pressure measures the force at which your blood rushes against the walls of your arteries as your heart pumps it through your body. The higher the force, meaning the higher your blood pressure, the harder your heart has to work. High blood pressure damages not only your heart but also your arteries. When your doctor or nurse measures your blood pressure, you'll see two numbers. The top number is called systolic blood pressure. That's the force of blood in your arteries whenever your heart beats. The bottom number measures diastolic blood pressure, or the force of blood in between heartbeats.   You're more likely to have high blood pressure if you don't exercise regularly, you're obese, you eat too much salt, you have diabetes, you smoke, or you have a family history of high blood pressure. Most of the time, you won't know that you have high blood pressure. That's because high blood pressure usually doesn't cause symptoms. Unless you get your blood pressure checked, you may have no idea there's a problem until you develop heart disease or another complication. If your blood pressure is high, a few simple lifestyle changes can help bring it back down, and prevent its complications. Eat a heart-healthy diet that includes plenty of fresh fruits and vegetables, whole grains, and low-fat dairy, avoid fatty, salty, and sugary foods, exercise at least 30 minutes a day, limit salt to 1,500 milligrams or less a day, that's less than a teaspoon per day, and if you smoke, now is the perfect time to quit. Ask your doctor for tips on how to kick the habit. If these measures don't work, your doctor may prescribe one or more medicines to control your blood pressure. Because high blood pressure can sneak in without warning, stop it before it starts. Stay healthy, and have your blood pressure checked at least once a year. If you already have high blood pressure, follow your doctor's advice to get it under control.

Tracking your blood pressure at home - Animation

Following your blood pressure at home has gotten a lot easier in the last few years. I'm Dr. Alan Greene. I'd like to share with you a little bit about that. Not too long ago when you wanted to follow your blood pressure at home, you had to have the old fashioned sphygmomonometer, and the device was a complex as that word sounds. You had to pump something up, and put a stethoscope in your ears, and fumble all these different tubes and even so wouldn't get a very accurate reading. Now, there are simple, high quality, digital blood pressure cuffs. They're easy to use at home. They're built so they snap on the arm very easily, just press a single button, and the chip inside does the work for you. It blows it up, it gives you the reading, and some of the newer models even connect it to your PC and track the readings for you. Now, how accurate are they? They're really pretty good. I wouldn't trust a single reading that much if you get one that's high or low. I wouldn't be either reassured or panicked. But, I would trust the pattern of readings. So, if you have one that tracks it for you, that's great, if not, just write them down what date and time you took it and see what the pattern is over time. If there's anything of concern, be sure to report it to your physician.
