Hi there . I do experience a lot of dizzy spells, almost every day. I have only fainted, more so blacked out, a handful of times though. It seems to happen mostly when I stand up, around my period, and sometimes when my sugar is way too low. I don't really know the rhyme or reason or if there is an exact cause, but I have heard it can be common for some endometriosis warriors to suffer with POTS syndrome. I haven't been tested yet, as I think it is sort of time consuming, but my symptoms certainly match. So I hope someday I can go get proper testing to rule that out. I would definitely keep a journal of every little time you feel dizzy or faint. What was the temperature, the weather, had you eaten or drank anything, how were you feeling, etc. It is time consuming but will be really helpful to have if you decide to see/talk with a doctor. Hoping you do get some answers and relief soon from this. -Kimberli (team member)
