    Tom Macdonald would describe himself as pretty relaxed-unless he sees the doctor. Then, suddenly, his blood pressure（血压） rises.

“I was a truck driver, I would be under pressure all day, dealing with traffic and long journeys to make sure we were on time, ” said Tom. “But I never got worried with work. Yet medical settings made me very nervous. ”

This wasn’t a problem until ten years ago when Tom developed an umbilical hernia（脐疝）. His doctor told him although not considered serious, if left untreated, a hernia can cause bad results. However. Tom’s situation created problems. “When I had my blood pressure taken in hospital, the doctor told me that I wouldn’t be able to have the surgery（手术）because it was so high. ”

Surgery for patients with high blood pressure can be risky. But when Tom’s blood pressure was later taken, the top number fell to below 140high, but not high enough to prevent surgery. “Soon afterwards, my doctor told me that I suffered from ‘ white coat syndrome（综合征）’.He explained it was seeing a doctor or being in a hospital that caused your blood pressure to rise even if it is usually normal. ”

“The main difficulty with white coat syndrome is that it only happens in a medical setting, which means you can’t really treat it,” says Professor Peter Sever, “You can’t send a patient away with medicine because once they get home and take it, their blood pressure is going to fall through the floor. ” The good news is that many people do gain control over the syndrome; knowledge can make a difference. “For some people, if they know they have it, they do seem to be able to take some control over it and it can improve,” says Professor Sever.

Many hospitals now have methods to solve the problem of white coat syndrome. They include the Will Adams NHS Treatment Centre in Gillingham, Kent, where Tom finally had his hernia repaired earlier this year.
