2 years ago I developed POTS which included lots of lightheadedness and orthostatic nausea. I was diagnosed 6 months later and successfully treated my symptoms w/ salt, water and exercise over the next 6 months until they were basically gone. However, since I started treating my POTS 1.5 years ago, I developed lots of gas and bloating, as well as nightly leg cramps and eye twitches which got progressively worse. I thought it may be salt irritating my stomach or an electrolyte balance so took a PPI for 6 months, which initially seemed to help but then it got worse again. I recently went for a blood test and found my haemoglobin has decreased from 12.5 when I was first investigated for POTS, to 9. something. Weirdly I don't feel my POTS/typical anemia symptoms are any worse than they were, except I haven't been doing much exercise lately which always makes me more lightheaded. I'm going for a follow up blood test in a few days time but am feeling at a complete dead end with my symptoms. Has anyone been diagnosed with anemia and what symptoms did you have.
