How Much Does Alcohol Affect Blood Pressure
Raises it, usually: Acutely, like in alcohol poisoning it can lower your blood pressure to shock levels- in fact many alcohol ods die of shock. Chronically, in heavier drinkers (3/day on average or more), it elevates blood pressure, and in fact is a cause of secondary hypertension. For the most part, people with elevated BP should drink very much in moderation, if at all. I ask my pt's to keep it to special occasion. ...Read more
Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
Caffeine can cause a short, but dramatic increase in your blood pressure, even if you don't have high blood pressure: It's unclear what causes this spike in blood pressure. Some researchers believe that caffeine could block a hormone that helps keep your arteries widened. Others think that caffeine causes your adrenal glands to release more adrenaline, which causes your blood pressure to increase. Some people who regularly drink caffeinated beverages have a higher average blood pressure than do those who drink none. Others who regularly drink caffeinated beverages develop a tolerance to caffeine. As a result, caffeine doesn't have a long–term effect on their blood pressure. It seems that caffeine has a stronger blood pressure increasing effect in men who are older than 70 or who are overweight. If you have high blood pressure, ask your doctor whether you should limit or stop drinking caffeinated beverages. If you're concerned about caffeine's effect on your blood pressure, try limiting the amount of caffeine you drink to 200 milligrams a day — about the same amount as in two 12–ounce (355–millileter) cups of brewed coffee. Keep in mind that the amount of caffeine in coffee and other beverages varies by brand. Also, avoid caffeine right before activities that naturally increase your blood pressure, such as exercise, weightlifting or hard physical labor. To see if caffeine might be raising your blood pressure, check your blood pressure within 30 to 120 minutes of drinking a cup of coffee or another caffeinated beverage. If your blood pressure increases by five to 10 points, you may be sensitive to the blood pressure raising effects of caffeine. If you plan to cut back on caffeine, do so gradually over several days to a week to avoid withdrawal headaches. ...Read more
Can increase it: Heavy alcohol intake (more than 4 drinks a day, or, after a binge) can increase your pressure a lot, by 20 points or more. I have seen patients whose pressure is 160/110 when they are drinking heavily (pint a day), and then have normal pressure of 130/80 once they go sober. Light alcohol (1-2 drinks per day for men, 1 drink / day for women) should not increase the pressure much at all. ...Read more
In Maaaaaany ways: Healthy arteries are flexible, strong and elastic. Their inner lining is smooth so that blood flows freely. If you have high blood pressure, the increased pressure of blood flowing through your arteries gradually can cause: 1) Aneurysm 2) Artery damage and narrowing 3) Hypertrophy - Heart Failure 4) Coronary Artery disease 5) Strokes 6) Kidney and Eye problems More important than people think! ...Read more
Drinking too much alcohol can raise blood pressure to unhealthy levels: Having more than three drinks in one sitting temporarily increases your blood pressure, but repeated binge drinking can lead to long-term increases. Heavy drinkers who cut back to moderate drinking can lower their systolic blood pressure (the top number in a blood pressure reading) by 2 to 4 millimeters of mercury (mm Hg) and their diastolic blood pressure (the bottom number in a blood pressure reading) by 1 to 2 mm Hg. Heavy drinkers who want to lower blood pressure should slowly reduce how much they drink over one to two weeks. Heavy drinkers who stop suddenly risk developing severe high blood pressure for several days. If you have high blood pressure, avoid alcohol or drink alcohol only in moderation. Moderate drinking is generally considered to be: Two drinks a day for men younger than age 65, One drink a day for men age 65 and older, One drink a day for women of any age. A drink is 12 ounces (355 milliliters) of beer, 5 ounces (148 milliliters) of wine or 1. 5 ounces (44 milliliters) of 80-proof distilled spirits. Keep in mind that alcohol contains calories and may contribute to unwanted weight gain — a risk factor for high blood pressure. Also, alcohol can interfere with the effectiveness and increase the side effects of some blood pressure medications. ...Read more
How low can you go?: Is not just about limbo, it can also be about your blood pressure. If your top number is 90 or less, the key is how do you feel? Dizzy, lightheaded [especially when you sit up or stand up], heart running fast, even passing out .... Not good. Talk with your doc! on the other hand, some people - especially athletes or yogis - feel fine & it's a sign of how healthy, body& mind, they are. ...Read moreSee 1 more doctor answer
Does not: Well women who are pregnant sometimes develop hypertension so there is a relationship between the two and if you have hypertension it can worsen when you are pregant but the hypertension does not relate to your becoming pregnant. Either way, if your blood pressure is high you need evaluation and treatment. ...Read moreSee 1 more doctor answer
Requires both muscle: to work harder to drive blood forward & ?es valve leaflet loads to block reverse blood flow. Heart muscle requires more blood flow for more work (more susceptible to damage of artery Ds), muscle gets thicker/stronger but also stiffer (no longer allows blood return from veins at low pressure) over time. Both lead to ?ed heart attack rates, enlargement, congestive failure, atrial fibrillation, etc. ...Read more
Impairs Nervous Sys: Chronically high blood sugar (diabetes mellitus) impairs the central and peripheral nervous system both directly and indirectly. The brain's only source of energy is glucose and chronically high readings (above 270 mg/dl) is associated with mild cognitive dysfunction. Indirect effects include acceleration of atherosclerosis increasing the risk for stroke and kidney failure. This is but a few ex. ...Read more
Yes: Caffeine can raise blood pressure by up to 10 points in people who don't have caffeine very often. This will lower back to normal when the effects of caffeine wear off. This temporary rise in blood pressure is worse in people who already have high blood pressure. If one consumes caffeine on a regular basis, it may raise blood pressure by a small amount over the long term. ...Read moreSee 1 more doctor answer
Several ways.: Smoking causes constriction of the blood vessels. This occurs less commonly in the veins as compared to the arteries. Smoking is one of the major risk factors for the development of atherosclerosis (hardening and narrowing of the arteries). In addition to this it can lead to intrinsic lung disease, which could then lead to thickening of the blood(polycythemia) which could lead to blood clots. ...Read more
15 min: The effects of the caffeine in soda should take effect within 15 minutes. Caffeine can raise blood pressure very slightly, but this should not be a problem unless you already have extremely high and uncontrolled blood pressure, or you are drinking gallons of soda a day, which wouldn't be good for many reasons. Hope this helps! ...Read more
