The Coronation Street actor told his fans he’d been taken to hospital.
Gareth Berliner, who plays Macca in the show, shared a snap from his hospital bed on his Instagram page.
Posting to his 3.3k Instagram followers, the soap star revealed he’d been taken to hospital in an ambulance at 1am on Friday morning.
The comedian has battled with Crohn’s disease for the past 30 years.
He has previously revealed he takes a nutritional feed into his blood via a tube in his chest.
Speaking of being taken to hospital, Gareth said: “Well, I was brought into hospital by ambulance at about 1am owing to some amount of sepsis ….vomiting and upset gut and a temp of 39.”
His following flocked to share their well-wishes.
One Instragram user said: “Hope you get well soon.”
While another continued: “No way, I’m sorry to hear that, wishing you a speedy recovery.”
Crohn’s disease is an inflammation of the gut – it affects how the body absorbs and digests food.
Speaking to the Mirror Online, Gareth said: “Having Sepsis of any kind is part and parcel of living with Total Parenteral Nutrition and just one of those things that happens from time to time. I’ve had TPN as a result of short gut syndrome for 19 years.
“I’m ok today… just stuck in here and they’re investigating what caused the issue. I don’t have a temperature anymore and am now being infused with some strong antibiotics to fight whatever bug is messing with my immune system.
“I am dressed and mobile as I see no reason to gets into PJ’s and give up.”
