Bloat is "inchar", more used to refer to "inchaço da barriga" (a bloated stomach) due to gas accumulation.

There are other concepts on that one, but I will be dealing with the pair bloat vs swell.
Other related expression is i.e. having a bloated ego.
as in: The promotion has bloated his ego to an alarming degree.

===========
Swell is "inchar" and more often used in English, it can be used in a literal way and as a figure of speech as well.

"The water swells the wood" (literally)
The toothache made her face swell up. (literally)


Too pleased with oneself; conceited. He's very swollen-headed about his success.
(figure of speach.)

=========================================
Here plenty of definitions to "swell" on context, anyway as I said before, I
stuck to the "inchar" definition. Viz-à-viz with "bloat"
