Q: Blood pressure?
I have a omron Hem-815f blood pressure monitor using your finger, and i was wondering if someone could help me with how you use it exactly and what is normal for it. the device is with batteries

A: hi, first of all the answer you just recieved from TinaO was really dumb. From my experience as a home care nurse, these bp cuffs are not accurate at all. You are better off returning it and using the blood pressure machines at the stores. Best to check approx same time each day and keep a record for your doctor. Good luck.

Q: blood pressure?
A doctor gives you an diuretic that will make you lose K+ in order to lower your blood pressure. HOw does it work? All I know is that this creates hypoalkemia and that the resting membrane potential of neurones are hyperpolarized

A: To answer it at the easiest level: Potassium (K+) is an ion that attracts water, drawing the water OUT of the cells making them hypotonic. That actually RAISES the liquid in the blood vessels (hypertonic) but it is quickly filtered off through the kidneys, causing a decrease in blood pressure. Once again it goes into the ion charge and diffusion across the membrane walls in the kidneys. Diuretics help you urinate and tend to draw off excess liquids to do this, lowering the liquids in the blood stream and the related pressure. Is this understandable? I can go into a more complex explanation but I don't know your level of medical understanding.

Q: Blood Pressure?
Im 46 years old, and my blood pressure is 147/91, do I need to be concerned? what is the normal range before treatment?

A: No, you have no need for concern. The averages for all the world population show that your systolic pressure is usually "100 plus your Age" - and you can't get much more average than yours, can you?....... It doesn't really matter about the diastolic (the lower one). You see, the B/P figures given by your doctor (or home monitor) aren't 'real' or 'true". By the simple laws of physics they CAN'T be. So, in spite of "received wisdom" your indicated figures are more a reflection of the state of your arteries than the pressures within them. And so, just like the colour of your hair, your eyes, the length of your arms, or shape of your knees, -or even inside leg measurements-, whether you're bald, or spotty, or handsome and dapper, these figure you read on your monitor are simply "YOU" - neither good, nor bad. Think about it... honestly, how on earth can the air pressure inside a bladder cuff wound round your arm tell the pressure within an artery!? Think of it as a fireman's hose pipe, and a truck going over it. - It all depends what the pipe is made of, yes? If it's cast-iron, or weak, elastic rubber, you'd get completely different pressures needed to stop the flow wouldn't you. - It's precisely the same with monitor cuff. On the other hand, CHANGES in indicated monitor pressures ARE pretty true. So if your B/P indicated readings suddenly change, then you should take those CHANGES seriously. However, you can safely ignore 90% of what you read on Answers. P.S. Edit ... Change that to 99.999% - see all the tosh above...

Q: How does blood pressure change depending on your body position?
I'm doing a lab for school, and I'm testing how lying down, sitting down, and standing up change blood pressure. However, the people in my lab lie down for 15 minutes, then take their blood pressure, then sit down for 15 minutes, and take their blood pressure, and then stand up for 15 minutes and take their blood pressure. How should the blood pressure change from these positions? Also, can someone maybe give me what they think might be an average person's readings for 15 minutes of lying down, sitting down, and then standing up?

A: your blood is being pumped by your heart into various valves and arteries and capillaries, when you are at rest for a while, some of the tubes that your blood moves through bend up like a garden hose... so when you stand up, all the blood that was waiting to move through starts to gush through, and that affects the overall pressure in your body

Q: What exactly is blood pressure and what are the risks if you have high blood pressure? Im curious?
I went to an eye appointment the other day, and they took my blood pressuure. They said that it was a bit higher then normal, and honestly im scared. What is high blood pressure and what does it cause? Also, are there ways to help lower blood pressure?

A: High blood pressure is when your blood vessels (the tubes that carry blood around your body) are slightly narrower for some reason causing pressure inside them. It could be due to cholesterol (which is like plaque that builds up in your blood vessels). A high calorie diet with inadequate exercise could cause cholesterol build up. Very high blood pressure due to very high cholesterol levels can lead to heart attack and stroke if not dealth with. However, some people's blood pressure has times when it goes high for a little while. Maybe you should get them to check your cholesterol level. Then they will be able to tell you whether or not it is due to something serious or not.

Q: How high can blood pressure get before a heart attack?
I spoke with my mom today. She's in her late 60s and has had high blood pressure for years. She still works regularly but is staying home this week to see if her blood pressure can be moderated after spiking to 236/145. (I'm not 100% sure about the second number--it may be a little off, but I am absolutely positive about the 236.) She was given a new medication, as well as some anxiety medicine. She's always had high blood pressure, but the 236 even scared her. So, how close is someone to a heart attack (or some other major body malfunction) when blood pressure goes that high? I remember my mom's mom had high blood pressure and died from a massive heart attack at age 70 about twenty years ago.

A: There is no number that causes a heart attack. So if your BP is say 236/120 for a few days nothing will happen. Or a brisk run or stress that drives up blood pressure for a few minutes or an hour is normal. Its the prolonged high blood pressure for YEARS that damages permanently damages one's heart. Yes, its the length of time that the heart sees this kind of a load that in the end causes damage to the hearts muscles, arteries, veins, valves and nearly every part of the heart. The liver, the kidneys and internal organs get damaged with high blood pressure for a prolonged period of time. This is irrepairable, so it is important to do everything possible to lower it to at least the160/100 mark . That includes a crash diet to get off any extra pounds like now. It is possible that if your mom has had this kind of a blood pressure for years, she has already damaged her heart and her liver and kidneys and of course that will geatly shorten her life. I dont mean to scare you, but I do want to scare you sufficiently to get mom to a Cartiologist immediately. Yes, a Cartiologist, not some Family Practice Doctor. What your mom needs is a new medical advice and treatment of kind. . Even if you have to drive a long distance, go to somewhere like the Cleveland Clinic for treatment or in Minnesota, the Mayo Clinic. These are examples, so find the best Heart Hospital around. I am mentioning this because your mom needs special kind of help to combat this high blood pressure. Not some oridinary doctor or even an ordinary Cartiologist. It is that important to get treatment right now at the level ive mentioned above.

Q: How soon would you reduce blood pressure with exercise? How long before you begin to see a change?
If I exercised for at least one hour on a treadmill a day, 7 days a week, how long before I'd notice a drop in blood pressure? Would it begin to take effect in under 6 months or no? I don't know if I'm phrasing this correctly, but I just would basically like to find out how long it would take for my blood pressure to start dropping if I were to adopt a healthier lifestyle and exercise (because I'm fairly sedentary due to my job). Thanks. (I'm looking for expert advice or advice from people who have lowered their blood pressure or know of someone who has. My goal is to lower my blood pressure and by extension my resting heart rate.) :) I'm not on medication. I used to have okay blood pressure, then through a series of traumatic events, I began eating a lot. I was severely depressed and I gained like 70 lbs. Horrible I know, but I was on medication depressed and I was practically suicidal. I'm better now and I want to work on myself, and be healthy and live a nice long life, but I don't want to be on medication for blood pressure or cholesterol so I want to lose the weight I've amassed. Is it possible or unlikely that if I lose the weight I've gained, and maybe a little more, through diet and exercise (focusing on whole grains/fiber, etc..) that I could return to a healthy blood pressure number? Or is it impossible to lose weight and exercise and eat a healthy diet to lower blood pressure? I would really rather avoid medication if it's at all possible because I feel like if it's through my own sedentary lifestyle and eating habits that I got this way, I would rather fix the problem than put a bandaid on it.

A: It is good that you want to lower your blood pressure by exercise. Yes, it will lower it by exercise. I have a family history of High Blood Pressure and heart disease. I have to watch my diet and exercise. I don't exercise that much, neither does my dad, but he is also on blood pressure medication, he noticed in a week. I am not on medication, but I also practice deep breathing and I lower mine within that time frame. I don't exercise as much, only when I feel like it. I try. My Blood pressure wasn't that high though. Mine use to be low, but went up because of some cold medication, we finally figured out what caused mine to go way up. Good for you for getting motivated. Here is some information on a website for you. I know it talks about medication, which I don't think you are on, which is good. It just happens to be on here. Good luck on getting healthier.:http://seniorhealth.about.com/library/howto/htbp.htm Here's How: Lose weight if you are overweight. Losing ten pounds can have a dramatic effect on blood pressure. Exercise daily. At least 20 minutes of aerobic exercise is recommended. Read nutrition labels, especially on convenience foods. Choose foods low in sodium (salt). Most fast-food restaurants post nutrition information in their stores. Reduce or limit alcohol intake. Stop smoking. Reduce stress in your life as much as is possible. Untreated sleep apnea can contribute to high blood pressure. If you snore heavily or feel tired even after a full night sleep, ask your doctor for an evaluation. Follow your doctor's orders and take prescription medications as ordered. Tips: Even a small amount of weight loss can lower blood pressure. Sudden, significant elevations in blood pressure should be reported immediately. Never discontinue a blood pressure medication except on the advice of your physician.

Q: What causes high blood pressure in a young man?
I am 26 I drink like a fish smoke like a freight train and have blood pressure averageing around 165/110. My drunken friend who lives the same life style has near perfect blood pressure. I think whole blood pressure thing may be a consipiracy to get me to go to the doctor about 38 times so they can make more money. Discuss.

A: There are so many things that can cause high BP, even in younger people. You should check your cholesterol. If they are both high that leads to different answers than if your cholesterol is low. There are many deficiencies that can cause high bp in people. You can be B deficient, and taking a B-complex everyday could lower it. You could be L-methionine deficient, and taking L-methionine along with B-complex everyday could lower it. You could be calcium deficient, or potassium deficient. Do you have any other symptoms? Do you have trouble sleeping at night? Does your skin itch? Do you have digestive issues? What foods do you usually crave or desire the most? All of these questions need to be answered before an answer can really be given. Your blood pressure is high, and it isn't a conspiracy just to get you to spend money. When your bp spikes, it can cause you to have a stroke. Smoking makes the bp worse, and makes it more likely that you would stroke if your bp spiked. You can't compare yourself to others because genetic make-up definitely effects what happens with us! If he genetically has low bp, then doing what you are both doing will raise it, but it will still be within the norm. You might already have a predisposition to high bp, and then what you are doing is exacerbating the problems you already have. You only have one body to live in. You can live fast, and die young in a smoking/drinking debauchery, or you can live a little more healthy, like quit smoking, and still do nearly everything else, but live longer. It isn't like you need to give up /everything/ just so you can live to be 100, but you need to consider how worth it is to you to take care of your body, and whether the un-needed strain on your body is worth it.

Q: How to lower high blood pressure in healthy teen?
I'm 16 and have inherited high blood pressure from my mom. They have ran numerous tests(kidneys, blood, urine, etc) and have found all to be normal. I am athletic and eat rather healthy compared to most teenagers. I rarely ever drink soda and never add salt to my food. What are some ways to lower my blood pressure? Eat more fruits and vegetables? Drink more water? I REALLY do not want to live the rest of my life taking a pill to keep my blood pressure low.

A: Try increasing your exercise and reducing your stress levels by not worrying. Meditation is good for lowering blood pressure too.

Q: What is considered high blood pressure for a 19 year old?
When I was at school, my university doctor diagnosed me with high blood pressure. I took medication (Atenol sp?) for a while before running out and summer vacation starting. I saw my family doctor at home now 3 months into summer vacation, and he said my blood pressure is fine. I recently decided to log my blood pressure over the past month. Thus far in the morning it's averaging at 135/79, and at night 136/85. Hypertension starts at 140/90, which it looks like I'm just beneath. My family doctor says im in the 95th percentile for my age in blood pressure, but 95 still in the range that it's normal... Should I be getting a third opinion? Could it be higher because of the stress at school? Should I be taking blood pressure meds? I really dont wanna die of a heart attack when I'm 35, so advice is appreciated here.

A: there is a lot of factor about u hbp, family gen, u dad or u mam has hbp too?? or bad diet , u have a hbp for sure and u have to take the atenol for a while in conjunction with a strict diet, try only vegetables, no salt, no sugar, change the white sugar for the brown, no sweets, change the sweets for fruits, no rice, change the rice for steam potatoes, on Saturday and Sunday eat meat white and red, avoid the fish and crab ..ah for sure avoid the coca cola and other sodas, avoid the orange juice and other no natural juices change for natural juices -avoid the sugar-. Avoid the alcohol and dont smoke. Do exercises Monday to Friday if you get tired only Monday to Thursday and rest Friday Saturday and Sunday, with 30 minutes run in the tread mil -4- is enough, and do abs and lift weight. Well i think is not the stress at the school maybe a little bit but for sure is about your body, maybe when u go to the doctor u get a little bit nervous, try to use u own bp machine at the school or in u free time anytime and u can check or usually at the supermarket. But for sure take u meds and keep u diet this is for long time, but dont worry everything is g b OK, u dont need to go to another doc is OK is not the end of the world.

Q: Blood Pressure - What is happening to my body to cause the systolic and diastolic pressures to change?
Hi, I have to answer that question relating to blood pressure for biology. If you could provide any links that would be very helpful. Thanks.

A: Heart pumping and relaxing

Q: What can cause high blood pressure in a female who was perfectly fine before she gave birth?
An associate of mine of normal weight and blood pressure, got pregnant and developed high blood pressure throughout her pregnancy. The moment she gave birth, the BP went back to normal. The doctor told her she should never get pregnant again. Against his advice, she got pregnant again and the high blood pressure not only came back but it stayed and has been with her since. Still a fairly normal weight, her BP can be normal one day and way the next. Any ideas on what could be causing this? It even has her doctors stumped.

A: A lot of times high bp is idiopathic, meaning doctors don't know the cause of it. A lot of women get preeclampsia or high bp during p/g it's quite common. As to why the high bp stayed with her after p/g there's no telling. Even just a 10% weight gain can affect bp as well as salt, caffeine ect.. If your friend loses a bit of weight, cuts salt out of her diet and stops any and all caffeine she might see improvement. But otherwise she may just need to take a simple bp med from now on. I myself have high bp and have had it for 6 years and i'm only 28. My weight is a factor and my history as a bulimic affects it too, but even when i was skinny i still had high bp. I just accept it and work to keep it down with medication,diet,exercise, and no salt or caffine. People can live long healthy lives on bp med sif necessary. It's not a huge life altering crisis..

Q: What position is blood pressure normally the highest and lowest?
If a person was sitting, reclining, or standing, which position would cause the blood pressure to be highest and lowest? Also, if there was an increase in blood viscosity, cardiac ouput, and diameter of the arterioles would this constitute to an increase in blood pressure as well?

A: blood pressure (BP) is usuall lowest standing position and highest in supine (reclining) position. This is because the blood return to the heart is decreased when standing.

Q: How does blood pressure apply to science?
For my final science project, I am taking the blood pressure of 6 students, three males, and three females. I hope to conclude whether the students blood pressure is higher in the morning before school, or after school in the afternoon. I made a prediction that it will be higher after school, when they are relieved that the day is over. My only issue is, that I have to tell how it applies to science. Does anyone have any idea of how blood pressure would apply to science?

A: Blood pressure is important in the study of the human body. If your pressure is to low then the organs do not get get needed oxygen if it is to high then it can damage the system. BP is measured systolic over diastolic (120/80) Systolic is the amount of pressure when the heart contracts and that's why its higher and diastolic is measured when the heart relaxes it is the amount of pressure let on the system.

Q: Why is blood pressure relatively more important than flow?
Why is blood pressure more important than flow. For instance, you can have a lot of blood that will flow through an artery, but that is not good enough, it must also be a certain pressure. Indeed pressure is almost more important than the absolute amount of blood that flows. Can anyone explain why this is true?

A: The blood pressure is directly related to the flow. Because the pressure is the highest right out of the heart and lowest coming back into the heart there is a pressure gradient. The greater the difference between the pressure coming out of the heart and the pressure of the blood wherever the blood happens to be going, the more flow there will be. We mostly concern ourselves with pressure because it is a good indicator of how things are going on acutely and also has long term consequences. When we talk about high blood pressure, we're concerned with the long term effect of excessive pressure on the various tissues of the body. Essentially we want there to be enough pressure to move blood along to feed all the body's tissues, but not so much that the pressure causes damage to other tissues. Flow is only a concern when we are talking about problems with the plumbing, usually to a specific area.
