Definitely the presence of blood in the urine is a cause for concern and a reason to go for a check-up with the doctor, since something is happening in the body and it is necessary to find out what it is to be able to give a solution as soon as possible.
In addition to blood, the presence of another symptom is very important when evaluating a person with blood in the urine (hematuria) and that is pain when urinating (dysuria); It is common to associate pain with the severity of a disease: the more it hurts, the worse.
However, that is not true in all cases. There are diseases that can be very severe and do not necessarily hurt like the diabetic foot, the greater the damage to the nerves, the less pain there will be; And that’s precisely the same situation in this case.
Blood and pain when urinating
When there is blood and pain when urinating, the possible diagnoses vary between: urinary tract infection (can be from the kidneys, ureters, bladder or urethra), renal lithiasis (stones in the kidneys or urinary tract) or prostate problems (can be infection, cancer or enlargement of it).
In these cases, the bleeding is usually due to inflammation in the affected part, for example, as the prostate is affected, it obstructs the passage of urine and the friction caused by this obstruction is what causes the bleeding.
In the case of stones (stones) the bleeding is due to the inflammation and injury that they cause as they go down from the kidneys.
Blood without pain when urinating
When there is blood, but there is no pain when urinating, then the possible diagnoses are different: kidney diseases (glomerulonephritis), clotting problems (Henoch-Schölein purpura), autoimmune diseases (such as systemic lupus erythematosus), anemia, among others.
In these cases, the reason for bleeding may change according to each disease.
Especially in kidney diseases, in the case of glomerulonephritis the bleeding is due to the fact that the kidney is damaged in such a way that it cannot prevent the blood from being “pulled” into the urine, in the case of anemia it is due to red blood cells are fragile and can break easily.
Medical review in all cases of blood in the urine
There are times when a person may present blood when urinating, but since there is no pain, then they do not go for a review with the doctor since they think it is not something serious.
It is important to clarify that regardless of whether there is pain or not, the presence of blood in the urine is not normal and therefore it is advisable to investigate what the cause is.
The evaluation of a person with this symptom should be complemented with a history to see if there are any extra symptoms, a physical examination and also laboratory studies that help guide the diagnosis.
