Around 4 yr ago I have a bad bout of gastroenteritis - I actually thought it was food poisoning but doc ruled that out- since then I've had constipation diarrhoea, stomach cramps,bad & irregular periods, anxiety attacks, mood swings, painful indigestion, wind & just felt generally crap!after colonoscopy, endoscopy, c.t scan & external & internal ultrasounds the doc said I had a stomach infection(now gone) an hiatus hernia & IBSa have been on Omeprazole 20mg daily and mebeverine 3times a day for around 2yrs now up to 3 month ago my symptoms just seemed to merge into 1long battle but then I started on Symprove and my life has improved dramatically. My constipation has more or less disappeared, I've found my triggers for diarrhoea, connected my indigestion to my triggers & got a grip on my anxiety BUT I still can't figure my periods out which in turn gives me mood swings. I have a normal period - sometimes a bit painful bit nothing major- they range between 3-4 wks but I get shocking mood swings & I have sort of mini periods after sex - lasting from an hour to 3 days or sometimes even setting my full period off- they're light & pain free but very inconvenient and just not a nice ending yo sex basically! Been to doc a few times but as nothing showed on the ultrasounds all she's willing to do is fit a Mirena coil, but I've read so many bad things about these & all side effects seem to be what I'm trying to get rid of! I also feel this is treating the symptom rather than finding the cause - so what I want to know is - does anyone else have this? Anyone have an idea what it could be causing it? Is it just part of IBSa? Any thoughts on the Mirena coil?
