High blood pressure/hypertension- what is it and why you should care...

Tasmia Ahmed, MD

We have all likely heard of high blood pressure, or "hypertension", at some point in our lives. Our grandmother may have been taking blood pressure medicines. We may have checked our own blood pressures out of curiosity at those little machines at our local pharmacy.  Or, perhaps our own doctor has mentioned high blood pressure to us.
  But, what exactly is high blood pressure, and why such a big deal about it?  Let's start with some numbers. High blood pressure, or "hypertension," is defined as repeated blood pressure above 140/90mmHg. Normal blood pressure is blood pressure up to 120/80mmHg.  The blood pressures in between 120/80-140/90mmHg are considered "pre-hypertension."
  How do these numbers affect our health?  According to the Centers for Disease Control, heart disease is the current leading cause of death in the United States.  About one third of all deaths above age 35 is due to heart disease, and hypertension is a major risk factor in the development of heart disease. Hypertension also increases risk for stroke, heart failure, and kidney disease.
  Just imagine trying to water your lawn using a garden hose that has a kink in it. You'll be working harder and struggling to push the water past the high pressure in the hose, and those flowers in your garden will suffer from the poor supply of water coming through. That is a simplified version of the way our hearts are working to pump blood through our arteries to feed our body's organs like the brain, eyes, kidneys, etc. With hypertension, our vital organs are suffering the damages of a high pressure system.
 The good news is that healthy lifestyle changes like regular exercise, lower sodium diet, and weight loss can significantly lower blood pressure, thereby decreasing the risk for stroke, heart attack, and heart disease.
  Aerobic exercise regularly can lower blood pressure by 5-15mmHg, and the intensity of the workout is more important than its duration. An easy way to improve our diet to a lower sodium diet is to limit or cut out the processed foods and canned foods. Eating fresh foods, and preparing your own meals can help reduce that excess salt in our diet. As for weight loss, there are many benefits to reaching a healthy weight, and better blood pressure is one major benefit. Every few pounds we lose can improve our blood pressure by as many points. Some people may also need medications to treat their hypertension and its risks.
 Now that we know more about hypertension, let's be on the lookout for it, and take healthy
 steps to help combat it. Talk with your doctor about your blood pressures and whether you have hypertension. Together, you can develop an individual health plan to keep you at your best.
