Rob Kardashian was admitted to a hospital Wednesday, Dec. 28, and Blac Chyna and Kris Jenner were seen arriving separately to be by his side.
TMZ reported that sources close to the family have said that Kardashian, 29, checked himself in for a diabetes flare-up.
Another source told Us Weekly that the attack was due to his stressful relationship and ongoing drama with Chyna.
"He's been so stressed out so [he's] not taking care of himself or eating right," the source said. "Stress affects his diabetes."
Kardashian and Chyna welcomed their daughter, Dream, last month but not long after her arrival they had a very public split which partly played out on social media.
"So I get home and Chyna took the baby, took the whole nursery we built. And Chyna took everything that we built for the nursery for the baby, Dream and she left and she just left me alone and took the baby," he said in a video on Dec. 17. "I'm pretty upset and I'm pretty sad because it's about to be Christmas and I want to be with my baby."
However, the two have reportedly reconciled since then.
