Is Canada's medical system pushing people abroad for treatment?

When Victoria residentNanciWalsh's weight shot up to 300 pounds, she decided to take a drastic step to save her life.

A series of major life challenges ranging from the sudden death of her father to a stressful lawsuit had led Walsh frombeing a life-long "bigger girl" to quickly putting on 80 pounds and sliding into obesity.

The weight gain triggered debilitating sleep apnea that required her to be hooked up to a ventilator at night, and her doctor told her she was likely facing diabetes as well.

She inquired about getting bariatricsurgery also known as gastric-bypass surgery to help her lose weight.

But the wait for her in B.C. for this surgery was five to seven years. So in 2012, Walsh took matters into her own hands. After some online research, she flew to Puerto Vallarta, Mexico to get it done there.

According to arecent report from conservativethink tank theFraserInstitute, Walsh is part of an increasing number of Canadians seeking medical treatment abroad.

The study has sparkeddebate about the adequacy of Canadian medicalservices and what really drives Canadians to risk going under the knife outside the country.

The FraserInstitute report says an estimated 63,459 Canadians receivednon-emergency medical treatmentoutside Canada last year, a steady increase over previous numbers.AndB.C. appears to beleading the country with the highest percentage of patients 2.4 per cent doing so.

More choices, says think tank

The report's authors saythe rising numbers are emblematic of the lack of private optionsin the Canadian health care system, which can lead to longer wait times.

But critics have bristled atthe study's findings andthe FraserInstitute's interpretation of them.

Jeremy Snyder, a member ofSFU'sMedical Tourism Research Group, saidmany Canadian patients seek medical treatment abroad for a range of reasons."There's really no foundation for concluding that the primary cause of medical tourism by Canadians is due to wait times," Snyder said.

YanickLabrie, a senior fellow with the FraserInstitute, disagreed.

"Why would they [go abroad]if they were able to get their treatment in a timely manner in Canada for free?" Labrieasked.

'Blunt and nasty'

Walsh agrees.

Back when she spoke with a specialist about getting bariatric surgery to help her lose weight, he told her it would be years before she could get the procedure done. He told her she wasn't a good candidate for it becauseshe was an emotional eater.

"He was very blunt and nasty about it," Walsh said. "I think he doesn'trealize how close he had put me to suicide."

She says getting the operation done abroad was the best decision she has ever made.

The $5,000price tagincluded a one-week stay for her and a guest at a five-star resort, medical files in English for her GP back home, and monthly follow-up phone calls for a year.

Nurses in starched white uniforms walked the halls of the modern hospital, in the samehighriseas a casino in a gated community,and doctors spoke to her in perfect English.

"It was the cleanest hospital I've ever been in in my life," she said.

The result, five years later, has been a sustained loss of about 120 pounds

'Horror stories'

But not everyone who receivesmedical treatment abroad receives gold-standard treatment, Snyder said, arguing that patients are taking great risks by potentially encountering sub-par treatment abroad.

And patients returning home with botched surgeries can end up costing Canadian taxpayers more money one study suggests medical tourism cost the Alberta health system $560,000 in one year.

"A lot of times the care is great but there are some horror stories as well," Snyder said.

He also questions how the FraserInstitute's numbers aregathered by asking specialists to guess how many of their patients sought treatment internationally in the past year, and then extrapolating the larger number from those results.

Health authorities don't track the issue.

'He really wanted to try it'

Based on interviews Snyder has conducted with Canadians who have gone abroad for treatment, he thinks there are many reasons that drive them to do so.

Snyder saidmany Canadians alsogo abroad to seek cheaper options for expensive elective surgeries, procedures that aren't legal in Canada (like paidsurrogacy), or experimental treatment.

The latter is what lead Canadian folk-rock icon John Mann to getunproven stem cell treatment in Mexicolast Januaryfor the early onset Alzheimer'she was diagnosed with.

"It's just so terrifying, the prospect of knowing what's going to happen with you with Alzheimer's," said Jill Daum, Mann's wife.

"For John, it was if there was even the tiniest chance that this might help, then he really wanted to try it."

The couple raised more than $56,784 US to cover costs for the treatment, which included spinal and intravenous stem cell injections and vitamin therapy at a clinic in Tijuana, Mexico.

Daum said there's no way they would have gone into debt to pay for the treatment themselves.

"If stem cells cured Alzheimer's, we would know," Daum said. "Everybody knew it was a long shot."

Daum doesn't think the costly therapy made much of a difference. But it did give Mann a boost of confidence as he slogged his way throughthe last concerts he would ever play.

"I think it gave him three months of hope," she said."He really literally had nothing to lose."
