My neurologist insists that MG has no connection – causation or otherwise – with urinary incontinence so please share any research studies that indicate they might be related. He says that urinary incontinence is controlled by a muscle group that is not affected by MG. For me, what was very occasional light leakage dramatically worsened just before and after my MG diagnosis in 2019. I don’t think Mestinon made it worse for me but I was only on it for a few months. It has continued with Cellcept. I do pelvic floor exercises my physiotherapist gave me which help but I’ve noticed that on days when I’m really active (i.e., babysitting my granddaughter), urination increases to like 20 times/day and is difficult to control. Worst is the frequent UTIs due to being immune suppressed, which are extremely sudden, painful and progress rapidly to not being able to leave my house due to lack of control. My family doctor won’t prescribe antibiotics before an infection, even though I get them like clockwork, so I didn’t take the last 2 pills of one prescription and kept them for the next infection so I could at least start treatment immediately and slow the progression. I get UTIs 2Xyear, sometimes 3.
