Michael Lohan is battling health problems as well as legal ones.

The father of Lindsay and Ali Lohan collapsed during an Alcoholic's Anonymous meeting on Tuesday and was taken to the hospital, according to reports.

"Michael started to feel light headed during his meeting so he walked outside, and that's when he collapsed," a source close to MiLo told Radar Online.

The diagnosis came soon after: "He was taken in an ambulance to Palm Beach Gardens Hospital where doctors found another blood clot in his lung."

Michael was given medication to break down the clot and the 51-year-old was given CAT scans and an MRI to make sure the clot hadn't spread to his brain.

Since Michael's hilarious arrest when he violated a restraining order and tried to flee police out of a window, he's split time between rehab and the hospital.

The ex-boyfriend of Kate Major had surgery to unclog his artery and repair blockage in his heart in early December, only to suffer from a staph infection.

He remains in the hospital now awaiting the results of a round of tests.

Whenever he's released, MiLo will be sent back to rehab, again.
