Kanye West is out of the hospital but he's not quite stable yet.  The issue reportedly stems from his irregular pattern of taking his medication, sources connected with the family tell TMZ.

According to those sources, Kanye has suffered from psychological issues for a long time, and they were controllable by medication.  Yeezy is steady when his medication is taken properly, but he deviated from the prescribed dosage and that is what led to the downward spiral and the eventual mental breakdown he suffered.

It's not clear if Kanye just stopped taking some of the pills or if he decided to take different amounts, but he reportedly made the biggest changes after Kim Kardashian was tied up and robbed in Paris.  Doctors were able to keep Kanye in the hospital for eight days, medicating him during that time and get him more stable.

He's now getting outpatient treatment and is okay right now, but since he's no longer under 24/7 observation, it's up to him and those around him to make sure he stays on the correct dosage.
