kidneys

Officials tested everything from drinking water to mosquitoes before the truth emerged: their kidneys had failed.

Ms Jones, from the Vale of Glamorgan, says she was born "with a defect in my kidneys" and has suffered with UTIs every other month since she was 18 years old.

Some symptoms can include fever, chills with cough, shortness of breath if the bacteria infect the lung, and pain or blood when urinating if the bladder/kidneys are infected.

Doctors say that when given to young children, drugs such as these can damage the child's heart, kidneys and liver, and can even be life-threatening if given for a prolonged period of time.

People with conditions affecting their kidneys should consult a doctor before taking it.
