One morning, Xiao C went to the toilet the same as usual, but inadvertently found that the urine in the toilet was red ? ! This scared Xiao C, who has always been timid and cautious! Moreover, she once heard someone say "Red urine may have cancer", which scared her to the hospital immediately ask about the reason.
But is Xiao C's red urine hematuria ? Does hematuria mean cancer risk? The answer to is definitely no! So what exactly causes abnormal urine color? With these two questions, let’s study this barometer in your body with Xiao C.
Is red urine hematuria?
Normally, normal urine should be transparent light yellow . This light yellow color mainly comes from urea after metabolism of and a small amount of urinary bilirubin and other products, and changes with the amount of urine, diet, drugs and lesions. The hematuria mentioned in our medicine includes naked eye hematuria and microscopic hematuria:
If one day you find that your urine is red, don't panic first. This does not necessarily mean that your body is sick. It may be just pseudohematuria . You can first recall whether you have taken food or medicine that can make your urine red recently... Let me briefly summarize the possible "pseudohematuria" situation:
food factors | drug factors | drug factors | other factors | other factors |
red heart dragon fruit, red amaranth , beet , carrots, broad beans, rhubarb , aloe vera , blackberry , blueberries, etc. | rifampin, aminobilin , doxorubicin, nitrofurantoin , phenytoin sodium, Warfarin, chlorpromazine , metronidazole , etc. | 1 Menstrual contamination, acne bleeding, etc. |
If none of the above situations are present, it is recommended to go to a specialist for help, and determine whether it is true hematuria based on the consultation and test results, so as to avoid misdiagnosis and misdiagnosis.
Is there a risk of cancer if hematuria?
We ordinary people cannot believe that hematuria is at risk of cancer based on subjective judgment. Further examinations must be used to clarify the cause of hematuria. For example, urine routine, urinary erythrocyte morphology examination, urogenital ultrasound/CT, kidney vascular color ultrasound, cystoscopy, renal puncture biopsy , etc.
Normal people may also experience transient hematuria under causes such as excessive exercise or some violent trauma. Therefore, when hematuria is found after excessive exercise, multiple re-examinations should be conducted every once in a while. If all are positive, further checks are needed for problems with the urinary system.
In addition, some people may experience orthostatic hematuria, the main reason is Nutcracker phenomenon , which is caused by the squeeze of the left renal vein by the abdominal aorta and the superior mesenteric artery, which blocks the return of the left renal vein and blood seeping of varicose veins in the renal pelvis.
Below I will list the common causes of hematuria:
, urinary system inflammation : acute and chronic glomerulonephritis, acute and chronic pyelonephritis, acute cystitis , urethritis , prostatitis , etc.
, urinary tract stones : renal pelvis , ureter, bladder , and stones at any part of the urethra.
. Urinary system tumor : Malignant tumors in any part of the urinary system or malignant tumors adjacent to the organs can cause hematuria when invade the urinary tract.
4, some other hemorrhagic diseases: , such as thrombocytopenic purpura, allergic purpura , hemophilia , leukemia , aplastic anemia , etc. can all cause hematuria.
Maintenance Kidney Tips
No matter whether the urine test is abnormal, it is recommended that everyone pay attention to the following points in their life:
. Drink more water, urinate frequently
Replenishing water can prevent the body from losing a lot of water and increase the metabolic burden of the kidneys. Therefore, people who urinate blood in must increase the amount of water.
. Develop good urination habits and avoid holding urine
In daily life, if there is a desire to urinate, you should excrete urine in time to avoid holding urine for a long time, which will cause certain metabolic waste or toxins to stimulate the urethra and even affect the functions of the bladder and kidneys.
, Avoid drug abuse
, especially painkillers, antipyretic drugs, proton pump inhibitors, antibiotic , etc. These drugs may have the risk of causing kidney damage and need to be taken under the guidance of a doctor.
4, regular physical examination
routine urine test, urinary ultrasound (especially over 45 years old), etc., to prevent problems before they occur.
