The former 'EastEnders' star was first rushed to hospital in August with septicaemia - a serious infection caused by bacteria or their toxins - but it seems she's still battling with the potentially-fatal illness because she's been dashing backwards and forwards for treatment over the past two months.

A representative for the blonde star told the MailOnline: "Danniella Westbrook has septicaemia caused by dental problems. She is very unwell and has been in and out of hospital several times over the last two months."

Danniella - who has battled with cocaine addiction in the past and had to have her nose rebuilt after her cocaine habit caused her septum to collapse - sparked rumours she'd relapsed when she was spotted with a plaster over her nose, but it's now been revealed her vigorous dental surgery has caused the infection and doctors were worried about it spreading.

Her spokesperson explained: "Steel rods going into her gum have caused an infection and therefore she is wearing a plaster with a sponge in her nose to stop the infection spreading."

Meanwhile, the 43-year-old actress revealed three months ago that she had to have all of her gnashers removed after contracting the illness.

She said at the time: "I've been in hospital. I've had to have all my teeth removed for a blood and bone infection, through no fault of my own. I'm not on drugs and I'm not pregnant ... I'm just very poorly with a blood infection."

Septicaemia is a type of blood poisoning, which is caused by bacteria, and can prove fatal if left untreated.

Urgent medical care at hospital is required to stop the infection progressing into sepsis, which occurs when the body's immune system goes into overdrive and can reduce the blood supply to vital organs such as the brain and heart.
