Though her sister's surgery went smoothly, Kandi's nearly turned tragic. Just hours after the operation, she went into cardiac arrest and was put into a medically induced coma (via Us Weekly). Despite fears that she might have suffered brain damage from lack of oxygen, Kandi made a complete recovery — and remained fixed on her goal. Per InTouch, both Brandi and Kandi dropped more than 200 pounds in the first year following their surgery, but they didn't stop there.

In the four years since their episode of "My 600-Lb Life" aired, they've both continued to drop the pounds to the point where they barely resemble their heavier selves now (via Shareably). Best of all, their new bodies have given them a new start. 

Kandi, who stays active on Facebook, posts every so often to share her joy with her followers. Her photos show her as a proud "Titi" to her two young nieces (yes, Brandi is a married mom now), whom she's nicknamed "Boog" and "Goob."
