Michelle Watt: 60 Minute Makeover host suffered depression due to spinal surgery

60 Minute Makeover host Michelle Watt took her own life because of chronic headaches caused by a spinal procedure, it has been revealed.

Her father, boxing champion Jim Watt, 66, said his daughter suffered crippling pain following a lumbar puncture that left her depressed.

The mother-of-one had the surgery to test for problems affecting her brain after suffering headaches and blackouts late last year.

After the lumbar puncture, in which a needle is inserted into the spine, doctors gave Michelle MRI and CAT scans, which revealed calcium deposits on her optical nerve.

Her father revealed that Michelle fell into a deep depression after the surgery, losing her appetite and her love of life.

"There was a problem with her optical nerve so they gave her the lumbar puncture to check for things like pressure on the brain," her father told The Scottish Sun.

"From that point her life was horrendous. She was in constant pain and wasn't sleeping. It knocked the stuffing out of her. Her appetite went and the weight was falling off her. She had no enthusiasm — she didn't want to see anyone or go anywhere. The spark just went. She just ceased to be Michelle."

"She hadn't had a decent night's sleep since the procedure and not sleeping is an illness in itself," he said. "It was a terrible time for Michelle and compounded into a deep depression. At that point she wasn't answering texts from friends, she shut the whole world out."

Jim said he noticed an improvement after Michelle received professional help for her depression, but nobody had suspected she might take her own life.

Her body was discovered in the £350,000 detached house she shared with husband Paul Kerr, 43, and daughter Jaymi, five, in Stirlingshire, Scotland.

Jim paid tribute to his daughter, describing her as "the most wonderful girl in the world". He added that her husband Paul and daughter were "shattered" by the loss.

Celebrity friends of the popular TV host paid their tributes. Lorraine Kelly posted on Twitter: "Absolutely shocked to hear of death of Michelle Watt. Lovely woman and a fantastic mum. Thoughts with her family and everyone who loved her."

Police have confirmed there are no suspicious circumstances surrounding her death.
