Hi all,
I was hoping for some clarification about POTS and its symptoms. I feel like I meet the medical qualifications, but I've never had lightheadedness or fainting symptoms. The reason I'm coming to all of you for help is that I saw my primary care doctor on Saturday, and she hadn't heard of POTS. She halfheartedly put me through the standing test, but dismissed me, because I don't feel lightheaded when standing.
I have been dealing with a wide array of health problems since I was about 12 years old. I have always believed that many of my symptoms are related to the digestive system and IBS. That said, I was diagnosed with MCAS two years ago. I was doing some research and found an article saying those with mast cell issues might also be dealing with POTS. Many of the symptoms of POTS fit, but then many do not. I've tested myself a number of times going from lying down to standing. Always, my pulse rate jumps to 30+ and remains at that level longer than 10 minutes. Usually, the supine pulse is 50-60 bpm, and my standing pulse is 90-115 bpm. An example might be the following:
Lying down
115/71 - 59 bpm
Standing
2 mins - 106/78 - 109
5 mins - 107/78 - 102
10 mins - 132/77 - 94
I know that my pulse rate and blood pressure used to be much higher. I've been on a restricted diet for 5 years, and that has helped bring my resting pulse rate much lower. In fact, a very restricted diet is the only thing that has allowed me to function close to "normal". I do have difficulty standing for longer periods of time. Eventually, I start feeling very uncomfortable and my body temperature rises. I also have to shift weight between legs, as I cannot stand comfortably with both legs locked, distributing the weight.
Could this all still be POTS, or something else entirely? There's much more to talk about and many more symptoms, but I don't want to overwhelm you with a huge post. Two things that have helped immensely is consuming smaller meals and drinking a ton of water during a day.
Thank you! I appreciate any input.
