Hello keepers51.
I am presumiing that the mucus you refer to leaks from the anus. This is a very common thing with those who still have one and I'm sure a lot of people will chime in on your post. If not, there have been a number of previous posts on the subject which can still be found in the 'collections' section.
I have had excessive and continuous mucus from the off, so had to find my own solution quickly. Fortunately (or not, depending on your perspective) , I was faecally incontinent prior to my stoma, so I needed to cater for that and was already well prepared for relatively minor leakages from that area.
At first I tried anal plugs, but they are made of the wrong sort of material for absorbing mucus, then I tried the plugs women use for their periods, these absorbed it, but were a liability, as they tended to get stuck, or get sucked further in, or, as on one or two occasions, the tail-end broke and the only way to get it out was using artery forcepts. Also, this tail-end on some of them is made of material and the mucus simply wicked out and was still as much a problem as when I wasn't wearing it. Thus, after so many failed experiments, I simply continued using incontinence pads. However, the mucus does not absorb very quickly into them so it needs slowing down to give the pads a chance. For this, I use a folded hand tissue (Toilet roll tends to disintigrate and is rendered useless), which catches the bulk of the mucus and slows it down so that the pad has a chance to absorb it more slowly.
It is interesting that I find the anal mucus more of a nuisance than the stoma. Probably because nobody warned me about it beforehand, so I wasn't mentally prepared.
I hope this information proves helpful
Best wishes
