Hematuria or Blood in the Urine – Causes, Diagnosis

What is hematuria?

 The presence of visible blood in the urine (hematuria, medical term) is not normal and is an occasion to consult the doctor, even if it disappears quickly or spontaneously. The cause of hematuria must be clarified because sometimes it can be consequence of a serious illness. Although adoption of medications that dilute the blood (anticoagulants or antiplatelet agents) could strengthen the hematuria, they are not sufficient to explain it. In these cases again it should not be underestimated and the reasons for its presence should be specified.

Hematuria may be accompanied by clots and in these cases you should take more fluids to dilute the urine (about 2 liters / day). Need of urgent medical attention is required only when blood clots are heavy and cause obstruction with inability to urinate spontaneously (the so called Tamponade ofbladder).
