Red morning urine in women

Under normal circumstances, people's urine should be white or yellow, but many women will find that the color of their first urine in the morning is red. This may be due to red blood cells in the urine, or blood caused by inflammation in the body, which eventually leads to hematuria. This does not rule out the possibility of kidney function or bladder and urethral system diseases, which may all cause red urine.

Whether red urine is hematuria or not, we should first clarify whether it is true hematuria or false hematuria. For example, vaginal, uterine, menstrual bleeding and hemorrhoidal bleeding can be mixed in the urine and blood cells may be found in urine tests.

There are other reasons why urine may be bloody, such as hemoglobinuria, porphyria, antipyrine, rhubarb, Congo red, phenolsulfonphthalein, rifampicin, etc. There are no red blood cells in these red urines, so these are not hematuria. In my outpatient work, I often see urine that is too concentrated to a dark brown color due to insufficient water intake and is considered hematuria. None of the above is true hematuria.

True hematuria: red blood cells are present in the urine. If the number of red blood cells in urine often exceeds 3 red blood cells per high-power field of view, serious examination and treatment should be received. If the urine looks like meat washing water to the naked eye, it is called gross hematuria. They should also be examined and treated.

Regarding the cause of hematuria: It is more common in children with acute red urine. Is it hematuria? First of all, we should find out whether it is true hematuria or false hematuria.

Regarding the cause of hematuria: it is more common in children due to acute nephritis and bladder stones. Bacterial infections, tuberculosis, stones, and nephritis are more common in adolescents or middle-aged people. Painless hematuria in people over 40 years old should be considered as a tumor or inflammation. Men should consider prostate disease. Accompanying symptoms can also indicate some problems: if accompanied by edema and high blood pressure, kidney disease may be considered. Hematuria accompanied by a kidney mass should raise the possibility of a kidney tumor. Stones and blood clots are common causes of hematuria associated with renal colic. Stones are especially common.

Frequent urination, urgency, pain, and other inflammations are common causes of hematuria. Hematuria accompanied by tuberculosis symptoms such as low fever, night sweats, and frequent urination should be urinary tract tuberculosis. Hematuria accompanied by bleeding in other parts of the body should be considered a blood system disease. Hematuria and urinary incontinence should be checked for filariasis, and chyluria caused by compression of the mass should also be considered. In general, anyone with hematuria should be examined and taken seriously.
