Is It Blood in Urine? When to Seek Medical Attention - Urology

Share to:

I just went to the bathroom and noticed what seems to be blood in my urine?


I just noticed something red in the urinal while urinating outside, but it quickly flowed into the urinal.
I'm not sure if it was blood in my urine, but the second half of my urination was normal.
Should I get this checked, or should I just observe it for now? I've never had any issues with blood in my urine before.
Thank you.

Hello, based on your symptoms, there is a high possibility of kidney stones.
Just because you haven't had stones before doesn't mean you won't have them now.
In addition to drinking plenty of water, please follow up with a urology clinic for further evaluation and treatment.

Blood in urine, or hematuria, can be a concerning symptom that warrants medical attention. While it may sometimes be a benign issue, it can also indicate underlying health problems that need to be addressed. In your case, since you noticed something red in the urine but it quickly flowed away, it is important to consider a few factors before deciding whether to seek medical attention.

Firstly, the presence of blood in urine can be caused by a variety of factors, including urinary tract infections (UTIs), kidney stones, trauma, or even more serious conditions like tumors in the urinary tract. If you have never experienced hematuria before, it is advisable to take this symptom seriously, especially if it recurs.

Here are some guidelines on when to seek medical attention for blood in urine:
1. Persistent Symptoms: If you notice blood in your urine again, or if it persists over a few days, you should consult a healthcare professional. Even if the blood is not visible but you have other symptoms like pain during urination, frequent urination, or abdominal pain, it is important to get checked.

2. Associated Symptoms: If you experience additional symptoms such as fever, chills, back pain, or difficulty urinating, you should seek medical attention promptly. These could indicate a more serious condition, such as a kidney infection.

3. Volume of Blood: If you see a significant amount of blood in your urine, or if your urine appears consistently red or brown, this is a clear sign that you should seek medical care immediately.

4. History of Medical Conditions: If you have a history of kidney disease, urinary tract issues, or other relevant medical conditions, it is wise to consult your doctor even if the blood in your urine seems minimal.

5. Age and Risk Factors: If you are over 40, or if you have risk factors such as a family history of kidney disease or cancer, it is prudent to have any instance of hematuria evaluated by a healthcare provider.

In summary, while a single instance of blood in urine may not always indicate a serious problem, it is essential to monitor your symptoms closely. If you notice any recurrence or associated symptoms, do not hesitate to seek medical attention. A healthcare professional can perform the necessary tests, such as urinalysis, imaging studies, or cystoscopy, to determine the underlying cause of the hematuria and recommend appropriate treatment.

In the meantime, keep track of any additional symptoms you may experience, and consider maintaining a diary of your urinary habits and any changes you observe. This information can be very helpful for your healthcare provider in diagnosing the issue. Remember, it is always better to err on the side of caution when it comes to your health.
