Hi Roz..... Been there... had that problem... shit everywhere!!! I have two solutions for you. Two things changed my life with an Ostomy. The first is simple and affordable and VERY effective.
"Micropore Surgical Tape" the 3M Brand is the only one that works. It is a very gentle paper tape which will not irritate the skin... ever!! This tape will not come off in water... in the shower or even in big Ocean waves. I generally tape the four sides of the Wafer... almost like a "picture frame" around the four sides of the Wafer. I use Two Inch tape... even Three inch. If a leak is beginning you will feel it under the tape... before the tape actually lifts and this gives you the critical few minutes to get to a bathroom.
"Absorbagel" is a Moisture absorbing powder (looks like Salt) which comes in little sachets about the size of a quarter. You open the end of the bag... after you empty it... and put in two or even three of the little packets (sachets). These will absorb most of the watery liquid in the Bag. What is in the Bag will end up looking and feeling like a thick Pudding and will no longer pose a threat as far as leaking. When I use the Absorbagel I can open the end of the Bag... just leave it open and hanging and NOTHING comes out... I have to squeeze the bag like... haha... Icing a cake... lol... It will not pour out if the bag breaks open in any way. Using these two products will give you a totally new life... I guarantee you!!! I introduced my G Friend (Osto Lady) to 3M Micropore Tape and the Absorbagel and it changed her life. I haven't had a leak in my bed for years!!!!.
I get Absorbagel in Ireland and it is available in England and possibly Canada. Have a look online and you will find it. It is quite expensive if you have to pay. About 75 Pounds for 150 sachets in England. If you use three every time you empty it can be expensive. Try using two when going out or going to bed... it will change your life totally!!! magoomoran@gmail.com.... please write and let me know if it works for you. The Tape is available (about 7 a 2 inch roll... can get it for a buck a roll on the Net!!!
Please try one or both, you will not regret it.
Eamon....
