Hi Clara
Watery output can be an issue because it can be easier for output to find its way between your skin and the appliance, instigating a leak and reducing time between changes. However, this does not apply to everyone all the time; mine tends to move between looser, to just like rainwater at times. There are a number of factors that will produce very loose output, such as drinking too much water too fast, as it will probably pass straight through; coffee can do the same and can contribute to dehydration. Many foods create loose output as well. Others have issues with output that is too firm. There are things such as psyllium husk powder, loperamide, and some foods which can firm up output, but I find the foods inconsistent, so I don't chase them. Looser output also has a self-cleaning action when emptying too 😂
You are still very early in the process and your body is still trying to work out what is going on and will for a while longer. In time, you will learn what works for you.
