My husband uses almost 10 Depends a day. Isn’t that a lot?

He may be having prostate problems, as is very common in elderly men. This causes them to urinate more often. Not sure there is a solution for this depending on your husband's cognitive level, since it will require a physical exam that is not very pleasant and requires cooperation. I would discuss this and the possibility of a UTI with his doctor.

Does he perhaps have UTI? That would cause him to pee a lot. And if not, he may just be finding it easier to go to the bathroom in his Depends, than making a trip to the bathroom. Your question is under the "Alzheimer's & Dementia" heading, so perhaps he is forgetting that he's supposed to try the bathroom first. Just be glad he's at least going in his Depends, as things could be a lot worse if he opted to pee elsewhere.(not in the toilet) And if perhaps he is a fall risk like my husband was, that could be part of the reason as well. Early on in my husbands vascular dementia diagnosis, he was getting up every hour on the hour to pee,(even though he wore Depends as well) and because he was a fall risk, I had to get up with him, because he preferred to pee in the toilet. And he actually peed a lot each time he went, which was quite surprising to me because he went so often. Because neither of us were getting any sleep, my husband ended up getting a supra pubic catheter(which is a permanent catheter), and that solved at least his peeing problem. Good luck.
