Regarding the issue of frequent urination?


Hello, Dr.
Hsu! For the past three days, I've been experiencing frequent urges to urinate, approximately once every hour.
If I've had something to drink, I feel the need to go even more frequently, about every half hour.
The volume of urine is not insignificant (around 100-150cc).
The color of my urine varies; the longer the interval between urinations, the more yellow it becomes, while shorter intervals result in clear, colorless urine.
I do not experience pain or discomfort while urinating; it feels normal.
However, I haven't consumed that much liquid, so I'm puzzled as to why I'm producing so much urine.

In addition to the frequent urination, I also feel a slight burning sensation in my bladder and penis at times, along with the urge to urinate.
This sensation comes and goes, and sometimes I feel the need to urinate again within five minutes after finishing, but I can't produce any urine at that time.
I visited a urologist yesterday, where I underwent a urinalysis, X-ray, and lumbar ultrasound, all of which returned normal results.
I haven't taken any medications recently, and the night before the symptoms began, I drank a cup of Ovaltine, after which the symptoms started the next day.
Since my visit to the doctor yesterday didn't yield any results and the symptoms persist today, I would like to ask you, what could these symptoms indicate? Is this a medical condition?

Chris: Frequent urination can indeed be an embarrassing situation.
It is a symptom that can have many causes, ranging from infections, stones, medications, to anxiety.
In your case, the amount of urine you produce each time, which is about 100-150 cc, is actually not too little.
The most likely reason could be the change in weather, which has become a bit cooler and may stimulate bladder contractions; alternatively, you might be drinking more fluids, leading to an increased frequency of urination.
Additionally, emotional issues are often a concern for individuals in your age group, especially related to relationship or work-related stress.
Furthermore, there may be small stones that are not easily detected by current examinations, which could also contribute to frequent urination.
My suggestion is that since your tests have come back normal, we should consider psychological factors.
Try to relax in your daily life, or consult a physician for some bladder stabilizing medications, which should help resolve the issue of frequent urination.
Sincerely, Dr.
Hsu Wei-Kai, Director of Urology, Taitung Hospital, Department of Health, Executive Yuan.

More Info


Frequent urination, or the need to urinate more often than usual, can be a frustrating and concerning symptom. Your description of experiencing the urge to urinate every hour, or even more frequently after drinking fluids, along with the sensation of urgency and mild burning, suggests that there may be several underlying factors at play.
Firstly, it’s important to understand that frequent urination can be caused by a variety of conditions. Some common causes include urinary tract infections (UTIs), bladder irritability, prostate issues in men, diabetes, and even anxiety or stress. Given that your recent tests, including urinalysis, X-rays, and ultrasound, returned normal results, it seems that a UTI or structural abnormalities in the urinary tract may be less likely.
The sensation of urgency and the feeling of incomplete bladder emptying can sometimes be attributed to bladder overactivity, a condition known as overactive bladder (OAB). This condition is characterized by a sudden urge to urinate that may be difficult to control, and it can occur even when the bladder is not full. OAB can be triggered by various factors, including dietary irritants (like caffeine or alcohol), certain medications, or even psychological factors such as anxiety.
In your case, the burning sensation and the urge to urinate shortly after voiding could indicate bladder irritation. This irritation can be caused by a variety of factors, including dietary choices, dehydration, or even stress. The fact that you mentioned consuming a drink (like the chocolate drink you had before the symptoms started) could suggest that certain foods or beverages may be exacerbating your symptoms.
It’s also worth considering that psychological factors, such as anxiety, can manifest physically and lead to increased urinary frequency. Anxiety can heighten the body's fight-or-flight response, which may lead to increased awareness of bodily sensations, including the need to urinate. If you find that your symptoms worsen in stressful situations or when you are anxious about being away from a restroom, this could be a contributing factor.

Given that your initial tests have ruled out some serious conditions, it may be beneficial to keep a bladder diary. This diary would track your fluid intake, urinary frequency, and any associated symptoms. This information can help your healthcare provider identify patterns and potential triggers for your symptoms.
If your symptoms persist despite these measures, it may be worthwhile to consult a urologist for further evaluation. They may recommend additional tests, such as urodynamic studies, which assess how well your bladder and urethra are functioning, or a cystoscopy, which allows for direct visualization of the bladder.
In summary, while your symptoms of frequent urination and urgency can be concerning, they may not necessarily indicate a serious underlying condition, especially given the normal results of your recent tests. However, it is essential to continue monitoring your symptoms, consider potential dietary or psychological triggers, and maintain open communication with your healthcare provider to explore further diagnostic options if necessary.
