Discussion in 'Problems Standing: Orthostatic Intolerance; POTS' started by Tony Mach, Jul 15, 2011.
Just wanted to ask if anybody has made any experience regarding caffeine and POTS.
I have no problems at all. Some get palps with it. Many feel better though. We are all different.
Here's what caffeine does to our bodies ... I only copied in a small portion of this article but the rest is fascinating. IMHO this is a must read for us ... I'm not sure if this article states that caffeine also causes cells to drop calcium but if you google caffeine calcium you'll find it.
I had to stop all caffeine in order to stop feeling jazzed up and crashing all day. It really didn't make me any more productive anyways. I just felt like it did while I was under the influence.

Helps me in short term but than causes exhaustion.
Don't know if he'll see this, so I thought I'd mention that I think Joey finds it helpful.
(mojoey that is...)
A cup of coffee actually seems helps me, but I know it's probably not good for my body in other respects. A pint of water is my only sure fire way of helping my POTS in the short-term as it seems to slow the heart down.... I have no idea why.
Caffeine seems to increase pooling of fluids in my extremities, which is weird since it should be vasoconstricting and a diuretic (should have the opposite effect). So, I'd have to say its decidedly negative for POTS in my n=1 experience.
Can be tested
Drug response testing. Every year thousands of people are send to the hospital from having an adverse side effect to medication. At DNA Testing Centres of Canada we offer a genetic test to determine if you are at an increased risk. We can determine genetically how you metabolize these drugs and weather they stay in your body longer then they should.
Are you taking any of the following types of medications? If so then we strongly recommend that you come in for a free consultation.
Abacavir For HIV and Aids
Aminoglycoside Antibacteriam medications
Carbamazepine mood stabilizing drug to treat epilepsy, bipolar disorders and trigeminal neuralgia
Clopidogel blood clot medication
Methotresate treatment of cancers and autoimmune diseases
Estrogen supplementation Oral contraceptive and hormone replacement therapy
Statin Cholesterol lowering medication
Tamoxifen breast cancer medication

Clopidogrel (Plavix) ... About Caffeine MetabolismPrintable Version Some people get jumpy after drinking a single cup of coffee, while others can gulp down a Venti Americano without feeling a thing. Part of that variability is due to the development of tolerance by regular coffee drinkers; but there are genetic differences in how people metabolize caffeine as well.

Caffeine is primarily metabolized by the liver enzyme cytochrome P450 1A2 (CYP1A2). The form of the SNP rs762551 a person has determines how fast CYP1A2 metabolizes caffeine. In this study, people with the slower version of the CYP1A2 enzyme who also drank at least two to three cups of coffee per day had a significantly increased risk of a non-fatal heart attack. The study found that fast metabolizers, on the other hand, may have actually reduced their heart attack risk by drinking coffee.

Caffeine seems to help me - I only have it in coffee and tea though so is a minimal amount.
Same for me it helps. And it can stop a migraine in the process. Never had caffeine much last couple days. Got migraine today. Got a coffee now = migraine diminishing i guess vasoconstriction.
I had a strong coffee and it made me collapse and I then couldnt walk due to POTS... so now im certain coffee has a negative impact as far as my POTS goes.
Ive read thou that caffiene thou helps some POTS people but others it has a negative effect on.
I have periods when even half a cup of coffee will make me fall asleep - Unfortunately it's not predictable
Took me a few times of having a coffee and being totally wiped out and much worse for a week to make the connection, but I'm pretty confident now that for some reason the caffeine triggers a major worsening of things for me. I figured probably something to do with the water loss. I've always been sensitive to caffeine and its diuretic effects. Probably just matters more now that I don't have much extra to lose.
