Rob Kardashian Leaves Hospital After Diabetes Scare

Rob Kardashian just left the hospital after getting treated for symptoms associated with his diabetes.

TMZ broke the story ... Rob checked himself into West Hills Medical Center Wednesday night near Hidden Hills. Our sources say he'd been stress eating because of his turbulent relationship with baby mama Blac Chyna. His weight gain and related issues triggered diabetes issues.

Rob left in a Maybach.

10:55 AM PST -- Almost simultaneously to leaving the hospital Rob posted an advertisement on Instagram about a weight loss program ... a seemingly huge bonus for the company, especially if potential customers think Rob's about to jump on board.
