"Keeping Up With the Kardashians" star Rob was recently brought to the hospital, and was diagnosed with diabetes.
According to TMZ, Kardashian started feeling unwell over the weekend, and was only taken to the hospital after his condition worsened.
He was later on diagnosed with diabetes, and he was unaware that he had the condition.
In an interview with People, a source close to the reality TV star revealed that he's still struggling with his weight loss.
"Rob is still struggling and it makes the family sad. He deals with depression, weight issues and low self-esteem, but that's been going on for a long time," the source said.
Back in October, Khloe spoke with the same publication about her relationship with her only brother.
Khloe and Rob are closest to each other. In fact, the latter has been living in the former's home for several months now.
"He's such a great guy. That's also what's so infuriating. He's charming, charismatic, everything. But I'm like, where is your will to live? Where is your will to live life? Let's be around people!"
Kardashian reportedly started excluding himself from others because he didn't like people talking about his weight gain.
There was also a time wherein he didn't appear much on "Keeping Up With the Kardashians" because he didn't want to public to see or poke fun on his appearance.
As of late, it is unclear how long Kardashian has to stay at the hospital, and whether or not his recent diagnosis will push him to finally lose weight.
