High & Low Blood Pressure board

Reading your post has made me wonder about the causes of low blood volume. Can they be readily identified? I guess I am wondering whether chronic hypotension (not drug induced hypotension) can be reversed by taking certain measures. Because blood pressure increases with the blood volume, if a hypotensive person could increase and maintain higher levels of blood volume, the blood pressure would increase. My reasoning probably sounds pretty naive. I am sure that in reality this is not how things work. When it comes to out bodies' function, nothing is that simple. :confused:It depends on the cause, it could simply be from a person not drinking enough fluids and eating enough sodium - though this is unlikely as a person starts craving salt at some point. Various medical conditions can cause salt wasting - Addison's is one of them, and other hormone problems can cause things to swing either way. Damage to parts of the nervous system, hypothalamus, or a problem with the kidneys can cause it. Basically, the kidneys don't know that they should hold the extra fluid (the same thing that can be caused by meds). Deficiencies don't help. Actual blood loss is the most direct cause - though most walking around with low volume obviously aren't experiencing this. lol

Some get symptoms, others don't. It makes heart problems such as mitral valve prolapse more noticeable symptom wise, and certain other illnesses like chronic fatigue syndrome tend be on the low side.

I don't know why I'm low. I've increased sodium and I'm always drinking water. My body simply does not hold onto it - what goes in comes right out. 16 bags of fluids in the hospital and drinking didn't do much. I'm not sure if it's my kidneys, brain, or nervous system causing them not to hold the fluids. I can't keep my potassium within a normal range, either. For several people, this can be the case - so while increased fluids and sodium may help it doesn't "fix" anything - Something I've chimed in on more than a few times on here.
I hang around this section precisely because not many here have experience with low BP or the other things that can cause/come along with it. :)

Again, chronic hypotension can come along with other illnesses or it can be the main symptom of one. That's why it is always best to see one's doctor if a person is feeling bad and their blood pressure is not good.

I have neurocardiogenic syncope - also called neurally mediated hypotension, with this and other autonomic nervous system problems there can be issues with blood pressure not staying up (and being low to begin with). When I stand my blood pressure either drops right away (orthostatic hypotension) or slowly falls. As with high blood pressure, hormone problems can be a big issue. If I could ever get my doctor to listen I would like to get a few checked out.
My doctor hasn't wanted to try florinef, yet. Maybe because I'm chronically hypokalemic?

I've tried up to 5gs of salt a day - it's hard to do and doesn't help me hold onto the fluids, only lose potassium that much faster.

I do wear hose because of some blood pooling issues in my legs. I'm not touching Sudafed since I have tachycardia.

Again, mine is nervous system related, as many others can be, so the typical things that would normally correct the problem only go so far. Even if I could correct the volume issue, I'd still have the nervous system problem that allows my blood pressure to fall (and me to lose consciousness). I honestly believe this is a lot more common then people think it is and people giving advice here should always consider it and related disorders as a possibility when the person is two things - 1) female and 2) within childbearing age.

Along with it comes weird reactions to things that usually do not bother healthy people, including medications. So it can be a bit dangerous to suggest some meds such as Sudafed.
Have you tried bringing your electrolytes back into balance? How about using potassium supplements, given a good kidney function? I know that doing so is not going to resolve your hypotension, as you mentioned, but it should be attempted anyway. So many of us struggle with electrolyte imbalances - potassium and a few others- on an ongoing basis. I too have been having some difficulties with these issues. Some of the antihypertensive drugs we take contribute to these imbalances. Abnormal electrolyte levels can cause many disturbances to the internal processes in our bodies. They can affect the cardilogical function to such an extent that changes are seen on the ECGs, thus adding to the side effects of our drug therapies. Of course, if your hypokalemia is chronic, correcting it might not be possible. We were able to correct mine by using several potassium holding/sparing drugs.

I read that a good way to get sodium is by using soya sauce in cooking. Personally, I can't imagine eating a high-sodium diet anymore, though I did for many years. Achieving and maintaining the right fluid balance, whenever possible, is very important for our blood pressure control and for proper function of our bodies. That is why we have several complex built -in mechanisms that regulate the blood volume.

[QUOTE=flowergirl2day;3786931]Have you tried bringing your electrolytes back into balance? How about using potassium supplements, given a good kidney function? Yep. OTC and prescription, even 16 bags of lacted ringer's solution doesn't make much of a dent for long. I'm lucky if I can stay at around 3.1.
What did not help was ongoing gallbladder problems. Now that's been removed I still have episodes of diarrhea - though this is not daily. The problem with always being low is that is doesn't take much for it to fall to a dangerous level.

I'm not really sure how much potassium is safe to take in supplement form. I believe it may be 4g max a day? but I do eat plenty of high potassium foods - except for bananas. I take magnesium, too, when I remember but this usually has to be before bed so I end up forgetting some nights.

I have to be careful with cooking. My husband has had a few blood pressure readings that I did not like (around 139/81) and I do not want to encourage his blood pressure to go up. His mother has high BP (and untreated at that :rolleyes:), so I'd rather not risk him.
Hydergine might be worth a try, very few side effects, no tolorance develops, and it seems to be quite effective.

Re a potasium suplement, I think in the US you can only get 99mg tablets, so you would need perhaps 10 a day, or, ask your doctor for a prescription for effervessant potasium tablets

Perhaps taking potasium tablets AND salt tablets would help, say after breakfast and dinner (they might irritate the stomach if it is empty)

Wearing compression stockings can help venous return and thus help improve blood preasure by stopping pooling of blood in the legs.

If this is realy effecting your life, push your doctor for Florinef (aask him for say a 1 month trial of it, and see if it helps).... and continue your potassium and salt supplements
