UPDATED 12/29/16 1:26 p.m. ET: Blac Chyna and Kris Jenner reportedly rushed to an emergency room Wednesday after Rob Kardashian "checked himself into the hospital because his diabetes flared up," TMZ reported. Chyna and Jenner arrived separately, with Corey Gamble accompanying Jenner as they "rushed into the E.R." just before 10 p.m. near Hidden Hills.

Sources close to the Kardashian-Jenner family told TMZ Thursday morning that Rob had recently gained an "alarming amount" of weight amid his tumultuous relationship with Chyna. In turn, Rob reportedly lost control of his diabetes. Kardashian later left the hospital Thursday afternoon, with TMZ reporting he had received treatment for "symptoms associated with diabetes." He reportedly left in a Maybach.

Chyna and Kardashian seemingly broke up earlier this month after an alleged Instagram hack and a drastic change in their living situation. Following a fight, Chyna reportedly left Kardashian and took their baby Dream with her. Kardashian later apologized on Instagram. "This weekend I was in an emotional bad place and did some things that embarrassed myself and my family," he wrote. "I apologize and I'm seeking help to deal with my flaws/issues. Please pray for me and I'm sorry @blacchyna. You are a great mother to our child and I love you [sic]."

Though Chyna and Kardashian appeared to hint at a reconciliation over the holiday weekend, subsequent reports have indicated that the relationship is still a bit rocky. Their E! series, however, is currently scheduled to continue for at least one more year. The network announced earlier this month that Rob & Chyna had been renewed for an eight-episode second season, set to debut in 2017. "Rob and Chyna's romance struck such a chord with our viewers, who were engaged in their story even before we started filming the first season," Jeff Olde, E!'s executive VP of programming and development, said in a statement to Complex. "We are excited to share the next chapter of their story."
