For starters, he's still struggling with kidney failure and receiving dialysis treatments. There has even been talk of him needing a kidney transplant.
When fans heard that Lamar might need a new kidney, fans were quick to offer up their own, which is a nice gesture and everything, but there are currently over 93,000 people on the kidney transplant waiting list, some of whom have been waiting years for a transplant.
As TMZ first noted, many fans have taken to Twitter to share their offer with Khloe Kardashian and Lamar, with some tweeting their blood type and others saying they would donate - for a price.
Obviously, the reaction has been mixed. "So he can destroy it with drugs. Try someone who cherishes their life. He have to prove change to me first," one person commented. "These regular people who have been fighting for years are waiting. Who wants to donate to them?" another wrote, along with a link to a Facebook page for people on dialysis.
Others are sympathizing with Lamar and defending people who choose to make that offer. "If anyone offers to donate for ANY reason, it is THEIR business! Be careful, you or a loved one may walk in similar shoes one day!" someone said. "Awww! That's sweet! That's probably the nicest thing I've ever heard a fan would do! Bless them!" another chimed in.
No word yet on whether or not Lamar will even need a transplant, but people are throwing their offers out there just in case.
