Gill Riley, from Warrington, Cheshire, began using a weight-loss injection she bought from a friend, who acquired it from an online pharmacy.
The 43-year-old woman believed the injection contained the same active ingredient as the blockbuster slimming drugs.
At first, she was thrilled with the results, dropping from 12st 3lbs to a svelte 10st 5lbs in just three months.
But in December she started to feel ill, which the retail worker initially brushed off as a case of the flu.
However, she ended up vomiting blood and collapsing on the bathroom floor — where she was found by her 11-year-old son.
She was rushed to hospital, where medics discovered the mother-of-four had signs of severe malnourishment.
Ms Riley also claims scans showed she contracted pneumonia, a dangerous infection of the lungs, which she blamed on the jabs weakening her immune system.
Doctors have also warned she may have suffered permanent kidney damage.
She has since vowed never to use weight loss injections again saying she feels ‘stupid’ she risked her life ‘to be skinny’.
Ms Riley said she originally purchased the unnamed brand of weight loss jabs from a friend who had acquired them from an online pharmacy, paying £90 for her portion of the prescription.
