Sydney woman received an extremely personal gift from her dad.

When Rachel Challen, 21, fell chronically ill as a teenager her father Jeremy Challen donated his faeces to her.

From the age of 15, the Sydney-based student suffered from chronic constipation. And while doctors prescribed her different medicines and diets, nothing stopped her from feeling bloated.

“There were days when I was in so much pain, I’d just have to go back to bed,” she tells the Daily Telegraph.

On several occasion she was admitted to hospital and she admits her mental health suffered.

“Dad always teased me when I was constipated,” she reveals.

“He’d say, ‘I’m like clockwork’. So when we were looking for a [faecal microbiota transplant or FMT] donor, I said, ‘Hey, you always say your bowel is like clockwork...’”

That’s when Professor Thomas Borody from the Centre of Digestive Diseases in Sydney, suggested Jeremy donate his faeces to his daughter to help retrain her gut flora.

The procedure involves transferring good bacteria and other micro-organisms from a healthy donor’s bowels to one with bad bacteria to help restore their gut flora.

“My condition no longer rules my life,” Rachel adds. "If my health went downhill, I’d definitely do it again."

And experts believe a FMT could help treat depression, as senior research scientist Dr. Michael Conlon says good gut flora can help improve brain behaviour, mood, obesity, rheumatoid arthritis and autism.

“There is potential [that] gut microbes play a wider role and there is promise this might work for a lot of things, we just need that opportunity to research using microbiota to alter other conditions,” he says.

Doctors in the US have also revealed that FMT could also he with fibromyalgia, alopecia and chronic fatigue.
