I’m doing a lab for school, and I’m testing how lying down, sitting down, and standing up change blood pressure. However, the people in my lab lie down for 15 minutes, then take their blood pressure, then sit down for 15 minutes, and take their blood pressure, and then stand up for 15 minutes and take their blood pressure. How should the blood pressure change from these positions? Also, can someone maybe give me what they think might be an average person’s readings for 15 minutes of lying down, sitting down, and then standing up?

your blood is being pumped by your heart into various valves and arteries and capillaries, when you are at rest for a while, some of the tubes that your blood moves through bend up like a garden hose… so when you stand up, all the blood that was waiting to move through starts to gush through, and that affects the overall pressure in your body

Is there a general rule for how antihistamines - as a class of molecules - affect blood pressure? Or is their no such generalization for either the affect they have on blood pressure or for all antihistamines in general, that is, maybe certain ones affect blood pressure differently. If their is such a rule, what is it and how does this occur, biochemically speaking?

In general they do not affect blood pressure.

Now, if someone were to have a severe allergic reaction, sometimes blood pressure can fall to dangerous levels, and antihistamines can to some extent prevent this.

I suffer from High blood pressure and high cholesterol what would be a good and safe workout in regards to weight machines and cardio machines. What should i push my heart rate too if my resting heart rate is 89 bpm. What percentage of my max should i lift?

Sorry you cannot do weight lifting, but you can do walking, even brisk, avoid fat, sugar, stimulants. and be stress free.

I know that chemoreceptors regulate blood pressure by monitoring the levels of H, O2 and CO2 in the blood, but why and how do these chemicals effect blood pressure?

I know that if too much CO2 and H is found in the blood by chemoreceptors, the medula oblongata will cause vasodialation (or constriction if there is too little im guessing) along with a slower heart rate. But how and why do these chemicals effect the blood pressure?

Recent scientific research suggests that a problem of the inner lining of blood vessel walls, called the endothelium Singular layer of flat cells that lines the walls of the heart, blood vessels, and lymphatic vessels; inner lining of the tunica intima layer of blood vessels, may contribute to hypertension. Substances released from the endothelium can cause blood vessels to dilate or constrict. Some substances also promote or inhibit growth of the smooth muscle cells in the blood vessel wall.

Normally, the actions of these substances are held in balance. But in some people, the constriction chemicals may overpower the relaxation chemicals. Arteries narrow, and blood pressure goes up because it is more difficult for blood to circulate.

What foods do you have to consume to prevent low blood pressure? How do you know if you have low blood pressure? Which is worse low blood pressure or high blood pressure?

High blood pressure is definitely worse. There is really no danger associated with low blood pressure, as long as it is not too low.
To prevent or treat low blood pressure, you should drink at least 8 bottles of water a day, and eat as much salt as possible in your foods.
If you feel like you are going to pass out when you stand you or sit up after lying down, or you notice that your heart rate increases a lot after changing your position from sitting or standing, these could be signs of low blood pressure.
If you think you might have low blood pressure, you should go to your doctor to check it out.

I would like to know what is the average or normal blood pressure in the morning, noon and evening.

its all diferent depending on your day. but 120 over 60 is a good one for a young person…

My dad has been suffering from high blood pressure for about a year now. He is at low risk for heart attack because he is very healthy, swimming at the gym every morning 5 days a week (although I’m not sure how good the genetics are). He has noticed just recently that the higher his heart rate is, the lower his blood pressure is. I’m guessing this has something to do with the physiological mechanism behind blood pressure and heart rate, so any additional information about that would be welcome.

The relationship between heart rate and blood pressure is complex. Heart rate and blood pressure vary during the day and are influenced by many factors. Medications also influence the heart rate and blood pressure. I know your father has high blood pressure, but I am not sure if he is on medications. There are certain medications that decrease blood pressure and increase heart rate, such as Hydralazine or Minoxidil. These are not routinely used for most cases of high blood pressure. Other medications decrease both heart rate and blood pressure, such as beta blockers. Many conditions associated with a low blood pressure such as dehydration will be associated with a reflex increase in heart rate. Sometimes if the heart rate is very fast the blood pressure can decrease. As you can see it is pretty complex and difficult to say the reason in your father’s case with limited information. If your father does not have symptoms like lightheadedness, then it is most likely nothing to worry about. He can discuss it with his doctor if he is concerned, because his doctor knows the details of his medical history. Good luck.

A year ago i was working out for 1 1/2 hours and running 3 miles a day at a maximum pace. I suffered a back injury, and havent worked out for about 10 months really. I gained about 30lbs, and my blood pressure has gone up a lot. I want to work out as hard as I can because I dont like easy workouts, but is it safe with high blood pressure? Can I hurt myself?

YES!!!!! You can cause a stroke or heart attack or annurisym if you are genetically prone to have one. Go to the Dr. 1st and get on a BP medication and as you work out check your BP frequently. It should lower just because you are working out again and then because you have lost weight and then you probably wont need the meds anymore. But be careful, if you exercise and drop your BP and dont check it you could pass out and doing this while your driving or whatever can be dangerous also. Rule of thumb is check your BP often and know what to do to raise your BP and to lower it quickly if you have to. There are many simple things you can do to lower your BP like bearing down (pushing like you have to go #2, but try not to hold your breath.)

High blood pressure is a malady that is associated with several complications. In some cases hypertension nurtures complications or diseases while in others it is a by product of various complications and physical states of humans.

A woman on family way has been often found afflicted with high blood pressure. The cause of this hypertension is also debatable like other types of hypertensions. Well, there could be two or three possible reasons of it. Wherein, the most prominent one is preeclampsia.

In case of this pregnancy induced hypertension, initially you witness a surge in systolic BP by thirty mm and diastolic BP by twenty mm. Presence of protein contents in urine confirms this type of hypertension.

It is just because of this preeclampsia resulted hypertension a pregnant is constantly required to keep track of blood pressure. This blood pressure complication usually arises in mid pregnancy. Women who have conceived for the first time are very much susceptible to preeclampsia. Pregnancy in late thirties or forties may also be a cause of such high blood pressure.

Among most pregnant women this preeclampsia propelled surge in BP is witnessed after six or seven months of pregnancy. This high blood pressure usually prevails till the delivery. Once the child is borne the hypertension lowers down and vanishes within few days. If a woman suffers a greater surge in blood pressure in her later stage of pregnancy, cesarean delivery before the scheduled date of delivery remains the only option. For, only the delivery would result in normalcy of blood pressure.

Although a less severe case of preeclampsia is difficult to be identified, a reasonably higher level of preeclampsia hypertension could be identified with constant headache, frequent vomiting, dizziness and blurring of vision.

A pregnant woman must be informed of various symptoms of this hypertension so that she could take immediate action once she finds herself with these symptoms.

This hypertension originates probably due to placental disorder. It is said that placental blood vessels constricts to result in hypertension. Women may also suffer from this complication due to less than required intake of various vitamins and nutrients that are essential during pregnancy. Some hormonal disorders may also contribute to this hypertension.

All in all, I would suggest all pregnant women to take preventive measures for preeclampsia as it adds to the ordeal of being pregnant.
