I do live in the Texas heat, and yes, the slime problem does exist. There are a couple of possible solutions. First of all, let me introduce myself. I'm your friendly neighborhood ostomy nurse. I live near Austin, Texas, and I too got my ostomy in 2009 for the same reason. Most people do not know how to use powder properly, specifically karaya powder, which is also known as stoma powder. It is not the same as talcum powder or cornstarch or anything like that. Those will actually make an appliance fall off faster than anything. Karaya powder is a type of natural rubber from the chicle tree. If you've ever heard of Chiclets gum, you have an idea of what I'm talking about. You can actually make a skin barrier out of layering powder if you know how. What you need to do is dust your area with powder, then moisten your finger and tap the powder down all over where your flange will go, and make a couple of layers of powder and a little bit of water, and it'll be very, very sticky, but you should still have enough absorbency in the powder. I'll try and make a video and show how to do this, but I have dialysis today, so not today. Tomorrow morning perhaps I will do my best, but yes, the Texas heat can be beat.
