Eli5 why do people who are battling cancer get so skinny?
In: 6
Chemotherapy targets cells that frequently divide, since cancer cells are always dividing.
It kills the cancer cells in large numbers, but also takes out a lot of digestive lining cells, hair follicles, and immune cells that also divide a lot.
With mass casualties in your digestive tract, you’ll struggle to eat much and keep it down. What you do eat doesn’t process as well.
