There has been frequent urination in the past two months?


Hello Doctor, I have been experiencing frequent urination for the past two months.
I need to urinate approximately every hour, with a measured urine volume of around 200 cc.
However, according to online information, the normal interval for urination should be 2 to 3 hours, and the volume should be over 350 cc, so I believe I am significantly deviating from the normal values.
After each bathroom visit, I feel a sensation of bladder fullness again after about 20 minutes.
When I press on my abdomen, it feels like urine is about to be expelled, which is very uncomfortable, and I constantly feel tightness in the muscles of my lower abdomen (similar to the feeling of holding in urine).
I can only hold it for an hour at most, and sometimes I accidentally leak a little.
However, at night, I can sleep through until morning, and the first urine volume upon waking is over 500 cc.
Additionally, I noticed that when I press about five centimeters below my navel, I feel slight pain when pressing deeper, and I'm unsure if this is related to the frequent urination or if it is a pre-existing issue.
I visited the hospital yesterday and will return next week to check the results, but I am worried it might be overactive bladder or a severe infection.
Thank you, Doctor.

Hello: If there is a significant decrease in urine output, it is important to seek medical evaluation.
Also, pay attention to any changes in medication, diet, or activity level.
Ensure adequate hydration and maintain regular bowel movements.

More Info


Frequent urination, or polyuria, can be a distressing symptom that significantly impacts daily life. Your description of needing to urinate every hour, with a feeling of urgency and discomfort, suggests that this is more than just a minor inconvenience. The normal frequency of urination is typically every 2 to 3 hours, with a volume of about 350 cc per void. Your experience of feeling the need to urinate every hour with a volume of around 200 cc indicates a deviation from these norms, which warrants further investigation.

There are several potential causes for your symptoms. One possibility is overactive bladder (OAB), a condition characterized by a sudden urge to urinate that may be difficult to control. This can lead to increased frequency of urination, urgency, and even incontinence. OAB can be caused by various factors, including bladder irritation, neurological conditions, or even certain medications.

Another potential cause could be a urinary tract infection (UTI), which can lead to increased frequency and urgency of urination, often accompanied by discomfort or a burning sensation. However, you mentioned that you have already sought medical attention and are awaiting test results, which is a prudent step. If a UTI is ruled out, other conditions such as interstitial cystitis or bladder inflammation could be considered.

The sensation of bladder fullness and discomfort in the lower abdomen you described could also indicate bladder distension or irritation. The fact that you can sleep through the night without needing to urinate suggests that your bladder function may be somewhat normal during sleep, which is a positive sign. However, the pain you feel when pressing on your abdomen could indicate an underlying issue that should be evaluated further.

Given your symptoms and concerns, it is essential to follow up with your healthcare provider. They may recommend additional tests, such as a urinalysis, bladder diary, or imaging studies, to better understand the underlying cause of your frequent urination. It is also important to discuss any other symptoms you may be experiencing, such as pain or discomfort, as these can provide valuable clues to your healthcare provider.

In the meantime, there are some strategies you can consider to help manage your symptoms. Behavioral techniques, such as bladder training and pelvic floor exercises, can be beneficial for some individuals with OAB. Additionally, keeping a bladder diary can help you and your healthcare provider identify patterns and triggers related to your urination.

If your symptoms persist or worsen, or if you experience additional concerning symptoms such as blood in your urine, fever, or severe pain, it is crucial to seek immediate medical attention. Your health and comfort are paramount, and addressing these symptoms early can help prevent further complications.

In summary, while frequent urination can be caused by various factors, it is essential to work closely with your healthcare provider to determine the underlying cause and appropriate treatment. Your proactive approach to seeking medical attention is commendable, and I encourage you to continue advocating for your health as you navigate this challenging situation.
