In TWW Blizz added this new thingy, the temporary max health loss bar.
In this pic the max health was reduced by 50%, but the player is still at 100% health, it's just the total available amount of hp that's reduced temporarily, my assumption so far is that it's due to some raid/dungeon mechanics/auras hence the "temporary" bit in its name. This bar is kinda similar to "Reserved Life" from Path of Exile.
