Yes and no. There's a few things that can help blood volume - fludrocortizone (a steroid that makes the body hold onto salt and fluids), something like erythropoietin to help a person make more blood. Less commonly DDAVP (to hold onto fluids) or IVIG (if it's related to illness) gets used. A common non pharmaceutical some have tried when other things make them ill is licorice root extract. Some rely on regular IV transfusion (ouch!).
But there's no guarantee that any of these will be of much help if something is messed up - for those of us with low volume our bodies think this is normal. The first line of treatment "drink more and eat more salt" doesn't always help because we just pee it all out (likely a problem somewhere along the renin angiotensin system).
For low blood pressure vasoconstrictors are sometimes used. These help the body constrict the blood vessels because they're not doing it well enough on their own. A common med for this is Midodrine (NASA uses it, too). There's also mestinon and another drug that will hopefully be approved in the US soon. There's also caffeine if it doesn't make one's heart react.
If there's tachycardia or other arrhythmias medication to control this may be used. It's great for some and for others it makes them much worse.
Another very simple way to fight blood pooling is compression hose. There's no chance of permanent damage to one's self but they're rather hot in summer and can be hard to wear.
All of these, even the hose, do have the chance for side effect - namely raising blood pressure too much.
So yes, there's treatments but finding a doc that even knows what's going on and whether it should be treated is difficult. Finding a doctor who is willing to do more testing to try to actually find out where the body is messing up seems to have the probability of getting struck by lighting...
But ultimately it's not as simple or easy as getting treated for many other things. Doctors tend not to worry when they see someone younger with a blood pressure of 90/60 or 90/50, they think this looks great (even when you report that you are taking medication to get your blood pressure that high) because they're trained that high blood pressure is serious and that low is good (unless very very low). Never mind that living with low blood pressure is very tough on some of us and can have negative effects. Getting pasted this first hurdle, unless one seeks a specialist, is tough. I wish luck to those who seek treatment. Don't give up if you're feeling terrible and if you drive and have had these symptoms while sitting, please do seek treatment!
