Rob Kardashian was rushed to a hospital in Los Angeles over the weekend but he is now recuperating at home after being diagnosed with diabetic ketoacidosis.

E! News recently confirmed that the 28-year-old reality star is now recovering after he was rushed by his family to an L.A. hospital Sunday. He initially complained about not feeling well, but his condition reportedly worsened at an alarming rate.

The doctors reportedly performed a series of tests and found out that he suffered from a conditioned called diabetic ketoacidosis.

Medline Plus defined diabetic ketoacidosis as a potentially life-threatening situation that affects people with diabetes. This condition happens once the body uses fat "when the body cannot use sugar (glucose) as a fuel source because there is no insulin or not enough insulin." If left untreated, people with this condition can experience diabetic coma.

Some of the symptoms of having diabetic ketoacidosis include deep and fast breathing, headache, stomach pains, nausea and vomiting, muscle aches or stiffness, as well as decreased alertness.

It was reportedly the first time that Kardashian learned that he is diabetic.

Kardashian used to be very active on TV and social media when he joined his family in the long-running reality show "Keeping Up With the Kardashians" on the E! network. But he has been away from the spotlight in the last two years because of his battles with depression and weight gain. He even chose not to attend his older sister Kim's wedding to rapper Kanye West to avoid the press.

A source reportedly told People magazine that Kardashian has to make a drastic lifestyle change to help him control his diabetes.

"He has to take medicine now to control his blood sugar level. He was also told he needs to rethink his whole lifestyle," the source explained. "He needs to see a dietician and change the way he eats. If he doesn't change his lifestyle, he was told that it could have serious consequences."
