, I would urge you to talk with your /dr. about getting dizzy after a stool. I am not giving medical advice with that urge. But from my experience it is not normal with Mg. But we are all different and could be for you. I do get that, but I have other medical conditions that can cause that. I do get very constipated before & during flares. I have for over 50 years. I was also diagnosed over 20 years ago with a neurogenic bladder caused by my undiagnosed neurological problem I just got diagnosed with MG in 2020 but have had it for 58 years!! (That was what the urologist told us/me.) That causes difficulty starting (if I can go at all) & incontinence. I ended up with Glomerulonephritis!! Please if you are having troubles like this talk with Dr. again, not medical advice just Glomerulonephritis is not something I would want anyone to experience, it's bad! The last sphincter in both the bowel & bladder is the muscle we can control. This is how we are potty trained. I was told this by an MG specialist!! So yes, MG can cause some of this!!!
