Undergo carries the sense of enduring a trial or problem. Examples: “He’s undergoing cancer treatment” or “she’s undergoing therapy.”
Undergoes is the simply the second-person tense: I undergo, he undergoes…

We don’t typically use the expression “undergo through.” Instead, we say “go through” as a kind of synonym for undergo. Example: “I know you’re going through a tough time right now…” OR: “Let’s go through this again” – in this case, “go through” means “to review,” and is synonymous with “go over” (“Let’s go over this again…”)
