Doctors told Danielle Yallop, a marketing boss at Manchester United, that her potentially fatal blood clot had been triggered by going to the gym too often.

She had to have emergency surgery to remove a rib after being struck down by a deep vein thrombosis, a condition most often associated with long-haul flights.

Danielle, who works out up to five times a week, was stunned when doctors blamed her fitness regime. She said: “I’ve always been a fit person and have never had any problems like this before and never imagined it would be caused by the gym.”

Experts say Danielle is just one of a surge in cases involving previously fit and healthy young men and women in Greater Manchester. They believe more patients are falling sick because of overdoing it at the gym – with their bodies unable to cope with the stresses of strenuous exercise.
