How to help my dad drink more water
Hello,
My dad has been diagnosed with S3 colon cancer. He's started immunotherapy and has been told he needs to drink more water. However, he's barely drinking anything, even less than he did before his diagnosis. He says he's really struggling with drinking (not swallowing issues) a mix of him not wanting to make effort and his energy levels.
What I'd like to know is if there's a way to get him hydrated without relying only on drinking. I've thought about things like fruit with high water content, but he's not eating much either.
It's currently a heatwave where we live, and I'm worried he's going to get badly dehydrated.
