Westlife’s Mark Feehily sues surgeon over weight-loss operation

Westlife singer Mark Feehily is suing a UK-based surgeon for medical negligence following a 2020 weight-loss operation. Feehily alleges that complications from the surgery led to recurring sepsis and eventually required the removal of his entire stomach.
Why it matters
The case highlights the risks associated with bariatric surgery and the legal accountability of medical professionals in high-profile negligence claims.
Westlife singer Mark Feehily has launched a medical negligence lawsuit in England against a surgeon who performed a weight-loss operation that he claims caused him to develop recurring sepsis.
The 46-year-old Sligo singer has spoken publicly over the year about the health issues that led to his hiatus from the group in 2024.
According to The Sunday Times, the singer’s health complications began in August 2020 after he underwent a laparoscopic sleeve gastrectomy, a type of weight-loss surgery.
The newspaper reported that UK-based bariatric surgeon Nick Carter failed to remove enough of Feehily’s stomach during the operation.
The tissue left behind allegedly caused a leak leading to severe abdominal infections, recurrent sepsis and hospital admission, until in 2023 he had to undergo an operation to have his entire stomach removed, known as a gastrectomy.
