engorged
Distended from fullness
Engorged means swollen with fluid, typically blood.
The word appears most often in medical contexts—engorged blood vessels, engorged breasts during lactation—and in descriptions of feeding parasites: The tick was engorged with blood.
Extended uses describe anything swollen to capacity: rivers engorged with snowmelt.
