Question
Hello doctor, in the past few weeks, I have noticed small brown spots near the opening of my underwear every time I shower and change my underwear.
I consulted a physician who believed it might be blood, but the urinalysis results were normal.
The results from another hospital the following day were also the same.
I do not have symptoms such as frequent urination or burning in the urethra, and I do not experience abdominal pain.
I am unsure why this is happening and whether I need further examinations.
One of the doctors suggested it might be related to my diet; is there a possibility of that?

That's strange! Are you sure it's urine? Could it be an issue with the skin of the genital area? I suggest you see a urologist for a thorough examination.

More Info
The presence of brown spots in your underwear, particularly near the front opening, can be concerning and warrants a thorough understanding from a urological perspective. Given your description, it seems that you have already consulted with medical professionals who have ruled out urinary tract infections (UTIs) and other common issues based on your urine tests. This is a positive step, as it helps narrow down potential causes.
Brown spots in underwear can arise from various sources. One possibility is that they are indeed related to blood, which could originate from several areas, including the urinary tract, the reproductive system, or even the skin. However, since your urine tests have come back normal and you are not experiencing symptoms such as frequent urination, burning sensations, or abdominal pain, it is less likely that the issue is related to a significant urological condition.
Another potential cause could be related to the skin or the genital area. Conditions such as folliculitis, which is inflammation of hair follicles, or other dermatological issues could lead to localized bleeding or discharge that may appear as brown spots. Additionally, if there is any irritation or friction in the area, it could lead to minor bleeding that might not be noticeable until it stains your underwear.
Dietary factors can also play a role in the coloration of bodily fluids. Certain foods, medications, or supplements can cause changes in urine color or even lead to discoloration in other bodily secretions. For example, foods like beets, blackberries, or certain medications can lead to reddish or brownish discoloration. If you have recently changed your diet or started new medications, it might be worth considering this as a potential factor.
Given that you have not reported any other concerning symptoms, it may not be immediately necessary to pursue invasive testing. However, if the brown spots persist, worsen, or if you develop any new symptoms, it would be prudent to seek further evaluation. A urologist may consider additional tests, such as imaging studies or a cystoscopy, to visualize the urinary tract more clearly if there is a suspicion of an underlying issue.
In the meantime, maintaining good hygiene and wearing breathable, loose-fitting underwear can help minimize irritation. If you notice any changes in your symptoms or if the brown spots continue to appear, do not hesitate to follow up with your healthcare provider for further assessment.
In summary, while the presence of brown spots in your underwear can be alarming, it is essential to consider various potential causes, including dietary factors, skin conditions, or minor bleeding from the genital area. Since your initial tests have returned normal, monitoring the situation and maintaining open communication with your healthcare provider is key. If symptoms change or worsen, further investigation may be warranted to ensure your health and peace of mind.
