A Country Antrim woman has claimed she is going blind after drinking 28 cans of Red Bull a day.

Lena Lupari’s weight rose to 26 stone as she spent roughly €8,500 per year on the energy drink, but she said she didn’t realise it was a problem until she collapsed in June of this year, the Belfast Telegraph reports.

She has developed Idiopathic intracranial hypertension, doctors say, as a result of her weight gain. The condition can mean an increases of pressure inside the skull. It is most commonly seen in overweight women in their 20s. Symptoms include headaches and changes in vision.

"I used to drink 28 cans of Red Bull in a day and I'd only have a meal at night but it would usually be something fast-food like a takeaway or a packet of pasta," she told the Daily Mail.

"I've got three young children, one with special needs, and didn't have time to make anything.

"I'd been suffering from migraines and headaches for about five years but I just ignored them and took painkillers.

"Then my vision went and I couldn't even lift my head off the bed and I ended up in hospital for six days."

Doctors have told Ms Lupari she needs to drop seven stone to keep herself free of the symptoms of the condition. She says she has since cut out Red Bull entirely and dropped two stone.

She has said she believes the NHS should held fund some of her recovery, perhaps with fitness camps rather than surgery.

"I don't want a gastric band or surgery but I think they should offer help for someone with this and to motivate them - something like a boot cam.

"Losing the weight doesn't mean it will go away forever but it means I won't need surgery," she said.
