Urinary problems


Hello doctor, I am a high school senior weighing 66 kg and standing 174 cm tall.
I often feel the need to urinate at school, about once every hour.
I drink a normal amount of water, and my urine output is neither too much nor too little.
After exercising (working out) after school, I usually urinate one or two times, which seems normal.
I generally eat quite a bit because I want to gain weight.
Is there any connection between my frequent urination at school and my eating habits? I have calculated that I urinate about six times a day sometimes, and other times around nine to ten times.
What could be the issue?

Dr. Wu Jiyu reply Internal Medicine


Based on your inquiry, urinating 6-10 times a day with each instance being over 200cc should not be a concern.
As for experiencing frequent urination at school, it may be related to stress.
If you are still worried, it is advisable to consult a urologist for further evaluation to determine if you have overactive bladder syndrome.
Thank you for your question, and the Nephrology Department at Changhua Hospital is here to support you.

Frequent urination, especially in teenagers, can be a concerning issue that may stem from various causes, both physiological and psychological. In your case, as a high school senior, it’s essential to consider several factors that could contribute to your symptoms.

Firstly, let’s address the physiological aspects. The average person typically urinates about six to eight times a day, but this can vary based on fluid intake, activity level, and individual bladder capacity. If you are drinking a normal amount of fluids and still experiencing frequent urination—like every hour or more—this could indicate a condition known as overactive bladder (OAB). OAB is characterized by an urgent need to urinate, often accompanied by increased frequency and, in some cases, nocturia (waking up at night to urinate).
In your situation, you mentioned that you are trying to gain weight and are consuming more food, which may lead to increased fluid intake, even if you are not consciously drinking more water. Foods with high water content can also contribute to your overall fluid intake, potentially leading to more frequent urination. Additionally, certain foods and beverages, such as caffeine, alcohol, and spicy foods, can irritate the bladder and increase the urge to urinate.

Another important consideration is the psychological aspect. Stress and anxiety can significantly impact urinary habits. As a high school student, you may be experiencing academic pressure, which can lead to increased anxiety. This anxiety can manifest physically, causing you to feel the need to urinate more frequently. It’s not uncommon for students to experience this, especially during exam periods or when facing significant life changes, such as preparing for college or entering the workforce.

Moreover, if you have a history of holding in urine due to limited access to restrooms at school or during stressful situations, this could lead to a conditioned response where your bladder becomes more sensitive, prompting you to feel the urge to urinate more frequently. This cycle can perpetuate itself, leading to a heightened awareness of bladder sensations and an increased frequency of urination.

To address your concerns, here are some steps you can take:
1. Keep a Bladder Diary: Document your fluid intake, urination frequency, and any associated symptoms. This can help identify patterns and triggers, which you can discuss with a healthcare provider.

2. Evaluate Fluid Intake: Ensure you are drinking an adequate amount of fluids, but be mindful of excessive intake, especially before activities where restroom access may be limited.

3. Manage Stress: Consider stress-reduction techniques such as mindfulness, meditation, or yoga. These can help alleviate anxiety and may reduce the frequency of urination related to stress.

4. Consult a Healthcare Provider: If your symptoms persist or worsen, it’s essential to consult a healthcare professional. They may recommend tests to rule out any underlying medical conditions, such as urinary tract infections, diabetes, or bladder dysfunction.

5. Behavioral Techniques: If overactive bladder is diagnosed, behavioral techniques such as bladder training or pelvic floor exercises may be beneficial. These techniques can help improve bladder control and reduce urgency.

In conclusion, while frequent urination can be concerning, it is often manageable with the right approach. By understanding the potential causes and implementing strategies to address them, you can improve your urinary health and overall well-being. If you continue to experience issues, seeking professional medical advice is crucial for proper diagnosis and treatment.
