What is High Blood Pressure? | New Hypertension Guidelines! | Doctor Mike

junio 4, 2018

[VidSitePro id=3 ]Hey guys what’s going on I want to take the time out and talk about a specific medical topic that’s been making headlines all across and use this week who should be diagnosed with high blood pressure blood pressure half of all adults redefining the danger zone plus it’s a medical issue that affects one in three individuals at least here in the States that topic is hypertension before we start talking about what hypertension is let’s talk a little basic anatomy the human body has a human heart the human heart has two ventricles the left ventricle is a strongest ventricle and that part of the heart squeezes and pumps blood to the rest of the body it does so through blood vessels called arteries arteries take blood and allow it to travel away from the heart the way we memorize that in medical school is a away from the heart a four artery when you measure blood pressure all you’re doing is you’re measuring the pressure that’s on the arterial walls and there are really three major factors that play a role in this pressure number one is cardiac output which is how much blood your heart pumps out with each beat number two is blood volume and number three is that resistance your heart has to pump against normally when you visit a doctor’s office or a hospital and you have a health professional measure your blood pressure you see them use a cuff that cuff has a name it’s called a sphygmomanometer as a mouthful I understand so we tend to use the term blood pressure cuff the way that the blood pressure cuff works is by constricting the arteries within your arm and while the doctor or other health professionals listening at the brachial artery you hear that first sound of blood rushing through the artery that’s known as the systolic blood pressure which is measured in millimeters of mercury and then when that sound disappears that’s known as a diastolic pressure sometimes you see the numbers written as a fraction the top number is the systolic number and the bottom number is the diastolic number the top number also known as the systolic blood pressure is the pressure during maximal contraction of your heart and a diastolic or bottom number is when your heart is completely relaxed well it sounds like taking a blood pressure is a fairly simple process there’s a lot that can go wrong and there’s a lot of room for error the blood pressure cuff is too small if the blood pressure cuff is used over clothing if the patient has a rested for at least five minutes if the arms back her feet are unsupported if the patients in an emotional state if the patient is talking if the patient just had a cigarette if the patient just drank a cup of coffee or had some alcohol if the patient is cold if the patient has a full bladder and really needs to use the bathroom all those things can throw off the blood pressure and make it look like your patient has high blood pressure when they really don’t because there are so many external factors that influence a person’s blood pressure we don’t give the diagnosis of hypertension until we have to elevated readings from two separate visits let’s do a little hypothetical here you or even your family member is diagnosed with hypertension what does that mean what are you at risk for doctors make a really big deal about hypertension so let’s talk about it hypertension damages the blood vessels throughout your entire body starting from your brain to your eyes to your lungs to your heart it’s your kidneys and even to your penis if you have a penis that is normally I don’t like to be the doctor that’s all doom and gloom but it’s really important to say that having hypertension significantly raises your risk of having a heart attack stroke heart disease and kidney disease this is precisely why hypertension is known as the silent killer because you don’t have symptoms until you already have some serious complications having your blood pressure well controlled decreases the risk of dying by 25% and it lowers your risk of having a heart attack and stroke by 30% now you want to treat your hypertension and you’re not necessarily keen on going the pharmacologic approach right away there are lifestyle changes you can make in order to lower your blood pressure naturally in fact 90% of hypertension is caused by poor diet lack of exercise and other bad habits so if you’re not exercising you should be doing moderate intensity exercise for 30 minutes on most days of the week next comes diet probably the most important thing that you can do to alter your blood pressure the DASH diet which is a specific diet which I’ll link down below is one that’s been proven to lower your blood pressure by 11 points one of the highest successes we’ve seen for a diet the two bad habits that have been proven to elevate your blood pressure is heavy alcohol consumption and smoking when we say heavy alcohol consumption what we mean is more than two drinks per day per week for a man and more than one drink per day per week for a woman when we speak about smoking we’re actually talking about smoking in any amount so do not be a smoker and do not be a heavy drinker if you don’t want your blood pressure elevated now these lifestyle modifications to lower your blood pressure work exceptionally well to prevent you from getting hypertension in the first place so I always like to think in terms of prevention rather than cures so follow these habits live a healthy lifestyle and don’t develop high blood pressure now let’s get into the numbers of the matter and talk about some of these new guidelines that are making a splash in the headlines across the news before we had these cut-offs where we diagnose people with either having normal blood pressure pre hypertension or what we called stage 1 hypertension or stage 2 and now those cut-offs have completely changed now a normal blood pressure is less than 120 over 80 and an elevated blood pressure is 120 to 129 over 80 and at that point we should recommend healthy lifestyle changes and check it every three to six months Stage one high blood pressure is now 130 to 139 over 80 to 89 which used to fall into the pre hypertension range that’s the major change within these new guidelines basically what we do is we plug in some of your statistics into a calculator and what it does is it spits out a risk or percentage of you having a heart attack or stroke within the next ten years if you have less than 10% risk we have to stress the lifestyle changes and again reassess in three to six months now if your blood pressure is over a hundred forty over 90 that’s considered stage 2 high blood pressure at this point we can start to consider a pharmacologic approach in addition to lifestyle changes in or to get your blood pressure to the normal values now under these new guidelines approximately 30 million more people in the United States will be defined as having hypertension and while that sounds like a dream for pharmaceutical companies it’s not a party for them just yet the reason being is that these 30 million people will be defined as having hypertension but only about 4 million out of those 30 million people will actually need pharmaceuticals to keep their blood pressure in check there are a few things these guidelines do really well the best research done in the last two decades proves that controlling blood pressure to a tighter limit of 120 over 80 actually yields better results and allows people to live longer and avoid heart attacks and strokes number two there’s a strong emphasis place on measuring blood pressure in the correct manner and number three they put a great deal of focus on lifestyle changes this is something I preach everywhere I go and with every patient I meet it’s much better to prevent this problem than to take a pill once it’s already there in the medical community we know we don’t treat hypertension well there’s a couple of reasons for that number one patients don’t often come in for screenings unless there’s already a problem and we don’t catch hypertension when we should and number two is when we actually do catch hypertension and we’ve tried lifestyle factors and they haven’t worked we prescribe a medicine and oftentimes patients are reluctant to take their medicines here’s the thing if a doctor recommends a medication I’m not saying you have to take it what I’m saying is if you tell your doctor you’re gonna take it take it because if you don’t you’re ultimately putting yourself at risk some people decide to not take a medicine because of its side effects there are alternatives you’re not stuck to taking one medication or these two medications there are definitely options and you should always talk about your worries with your doctor because the last thing that we want as doctors is for you to have a problem and not have it treated simply because of a miscommunication high blood pressure is a complex topic and it has major implications for your health I hope this video was able to demystify a little bit of what illnesses and steps that you can do to not only prevent it but to treat it in case you already have it I know I didn’t cover everything there is to know about hypertension within this video so if you have some remaining unanswered questions leave them down below in the comments so I can respond also if you enjoy this format please let me know because I want to continue making content that you guys enjoy as always stay healthy and happy see you next Sunday why can’t I say it blood pressure blood pressure a little blood pressure it’s called a sphygmomanometer a sphygmomanometer that’s the right word see can these sirens stop today like I just don’t understand is there an emergency everywhere on 42nd Street just leave guys come on high blood pressure but only about 4 million out of those 30 million will actually need pharmaceuticals to keep their blood pressure under check under check let’s do it again [Music]
