explain why smoking causes a rise in blood pressure?

Answer 1

Nicotine is a powerful vasoconstrictor of the peripheral arteries and that of coronary arteries.
It's vasoconstrictor results in rise of blood pressure, due to increased output of the heart to provide oxygenated blood to the body.
NB:
one cigarette's nicotine if extracted purely and given I/V can kill 100 persons. Source Goodman Gillman Pharmacology.

Answer 3

Just about ever abnormal lifestyle will do that. Even being angry too often will do that.

Smoking affects the lungs, and oxygen affects the bloodstream. Imagine that a lack of it will affect your heartrate. Anything that affects heartrate will affect your bloodpressure.

This isn't a technical explanation, but I'm trying to illustrate that although it doesn't seem to, it will increase your blood pressure.

I've smoked before, but I've only smoked about 8 cigarettes in my whole life. I smoked five on New Year's Eve, and 3 on another non-occasion. The more I smoked, the sicker of it I got until it got to the point where I couldn't even stand the smell of it. For some reason, I've only done it like a few times here or there, the way it was meant to be. Some smoke 5 packs a day! Basically, that's like walking around with the Grim Reaper following you anywhere you go.

Answer 4

Smoking does not cause high blood pressure. However, it can temporarily raise blood pressure, and it DOES increase the risk of heart and blood vessel diseases. Smoking injures blood vessel walls and speeds up the process of hardening of the arteries. So even though it does not cause high blood pressure, smoking is bad for anyone, especially those with high blood pressure. If you smoke, quit. If you don't smoke, don't start. Once you quit, your risk of having a heart attack is reduced after the first year. So you have a lot to gain by quitting.

Answer 5

3 years ago, I was diagnosed - hypertension with a reading of 160/100. I used to feel dizzy a lot, my legs had awful cramps, and levels were very low in my potassium, causing my fingers and toes to always cramp together. One day I started to feel really faint while I was driving with my daughter in the back seat and I passed out, hitting 3 cars and ending up in a ditch. That moment,I knew I had to do something because my meds weren't working. I heard about this diet from a friend and thought I'd give it a shot. The results have been remarkable. In just 21 days, I honestly can't remember feeling this good, my blood pressure went from 175/110 to 125/70.

Answer 6

You should read "The Blood Pressure Solution" (also available in electronic format, watch the video presentation here: http://www.fixbloodpressure.com ) It's a very comprehensive step-by-step book that walks you through the natural remedies of high blood pressure. It provides you with a lot of information on what foods to eat, how you can acquire and prepare these foods, how you can change your lifestyle for the better, how to eliminate the toxins from your body, how to reduce stress, how you can check your blood pressure level the correct way etc.

The book is amazing in that it not only lowers your blood pressure without the help of medications; it also aids you in having a life that is healthy, happier, and less stressful. This book chanced my life.

Answer 7

Because a cigarette contains nicotine. Nicotine acts on the nicotinic acetylcholine receptors. In small concentrations it increases the activity of these receptors, among other things leading to an increased flow of adrenaline (epinephrine), a stimulating hormone. The release of adrenaline causes an increase in heart rate, blood pressure and respiration, as well as higher glucose levels in the blood.

Answer 8

Your circulatory system has to work harder to pump the blood due to your narrowed veins and arteries. And your heart has to work harder to pump that blood, too. Imagine drinking through a regular straw then trying to drink through a straw that lets 75% less pass through...you'd have to suck harder to get liquid through it, right? Same principal with elevated blood pressure and narrow veins. Once you quit smoking the narrowing should relax and your blood pressure should return to normal pretty quickly.

Answer 9

You're blood doesn't carry as much oxygen per liter (or whatever unit of measurement you want to use) so it takes more blood to get the same amount of oxygen to you're body. Because you still require the same amount of oxygen, but have less capability of carrying oxygen to your body, you're heart pumps more often and faster to compensate.

Answer 10

It narrows the blood vessels. The same volume of blood must be pumped through the body, but the passageways are constricted, so it has to be pushed harder (more pressure).
