Health officials say women should only be diagnosed with a urinary tract infection if they have at least two symptoms.
Doctors have been told they should only give a diagnosis if women under 65 have two "key symptoms" of infection - including a burning pain when passing urine, needing to wee more at night and "cloudy" urine. New advice on diagnosing these infections also warns that medics should rule out other causes before diagnosing a UTI.
The National Institute for Health and Care Excellence (Nice) said that diagnosing UTIs correctly will "support appropriate management" and reduce the unnecessary use of antibiotics. It also made recommendations on the length of time adults should be put on antibiotics to treat "uncomplicated" bladder infections, also known as cystitis.
