Going Too Far Down
Ironically, it’s high blood pressure that may put you at the most risk for low pressure, because doctors may dish out pharmaceuticals that are too powerful in lowering blood pressure. A study in California by Kaiser Permanente shows that when doctors prescribe medications that push people’s systolic blood pressure (the top number in a blood pressure measurement) below 110mmHg, those folks taking the drugs suffer a doubled risk of falling and fainting.1 You probably know that a broken hip can be a tragic event for an elderly person, so this is a case where the medication causes more problems than it solves. The researchers warn that the risk of falls from these medications also goes way up in people who already have what’s called “orthostatic hypotension” – a condition which causes blood pressure to plummet when you get out of bed or even stand up from a chair. Orthostatic hypotension is much more widespread than most people know. Studies show that one in twenty middle-aged people now have this problem.2 Get to your sixties, and it’s one person in five. In your late seventies, a study at Texas Southern University found, it may afflict as many as 50 percent.3 If you understand the physical forces and muscular actions that take place inside of you when you stand up, say researchers, you can easily see why orthostatic hypotension is so widespread. The muscle contractions that bring you to a standing position squeeze an increased amount of blood through the veins back to the heart. That increase is sensed by the heart and arteries in a way that slows the heart’s pumping action, lowering both blood pressure and blood flow. Normally, the drop in blood pressure only lasts for a moment and the heart re-establishes normal pressure almost immediately. But aging can slow the heart and body’s response. And blood can pool in your legs.4 The result is a light-headed feeling or vertigo that can topple you to the ground when you get out of bed or rise from a chair.Dealing With Orthostatic Hypotension
Orthostatic hypotension can also be a common side effect of certain medications. These include:- Diuretics such as thiazides and furosemide which are used to treat high blood pressure and edema.
- Venodilators like nitrates that are used to treat heart failure.
- Anti-depressants such as amitriptyline and nortriptyline
- Direct vasodilators like amlodipine, hydralazine, nifedipine and alpha antagonists that are used to treat high blood pressure and heart failure.
Other Tips to Ward off Plunges in Blood Pressure
As I said before, there are also many natural ways to deal with the difficulties of orthostatic hypotension. For instance, experts advise drinking two to three liters of water every day. That’s about a half to three-quarters of a gallon. That’s supposed to help keep up your blood volume.5 Increasing your salt intake to 6 to 9 grams is also helpful.6 Salty soups and broths are good. Along with keeping your water intake up throughout the day, researchers have also found that if you need immediate help because you’re starting to feel woozy, rapidly drinking about half a quart of water can raise your blood pressure in five to ten minutes and keep it up for about an hour. Researchers note that drinking water this way produces “the time line of a very short acting medication.”7 Other helpful measures include:8- Wear abdominal binders (stomach wraps) and compression stockings. These have been shown to help maintain blood pressure.
- Sleep with the head of your bed elevated.
- Eat smaller meals with less sugar since sugar and refined carbohydrates can increase the risk of orthostatic hypotension. Avoid alcohol.
- Get some gentle exercise every day. Experts recommend activities like swimming and recumbent biking which don’t involve being on your feet.
- Try to stay cool. Avoid very hot baths and showers which can bring on dizziness. Don’t be outside too long in very hot weather.
- When you rise, get up slowly not suddenly.
- Don’t stand for long periods of time.
