Frequent urination issues?


Hello, I am currently in the first year of junior high school.
I have been experiencing constipation for the past two days, and today I frequently feel the urge to urinate, but the urine volume is less than 100cc.
I also have nocturia, which I didn't have before.
What could these symptoms indicate? Thank you.

Hello: Urination is related to lifestyle, diet, and water intake.
First, drink more water, aiming for over 2000cc a day.
Avoid beverages and spicy, irritating foods.
Walking for half an hour daily should help with recovery.
If symptoms persist, medical attention is necessary.
Wishing you good health.

More Info


Frequent urination, especially in adolescents, can be a concerning symptom that may arise from various underlying causes. In your case, the combination of recent constipation and the urge to urinate frequently, with a low urine output, suggests a few potential issues that warrant further exploration.

Firstly, it’s important to understand that the urinary system and the gastrointestinal system are closely linked. Constipation can lead to increased pressure in the abdomen, which may irritate the bladder and create a sensation of urgency or frequency in urination. This is sometimes referred to as "bladder irritability." When the bowel is distended due to constipation, it can push against the bladder, leading to a feeling of needing to urinate even when the bladder may not be full.

Additionally, the fact that you are experiencing nocturia (the need to urinate at night) is noteworthy. In adolescents, nocturia can be caused by several factors, including increased fluid intake before bedtime, urinary tract infections (UTIs), or even psychological factors such as anxiety. Although you mentioned that you have not experienced this symptom before, it’s essential to consider any recent changes in your lifestyle, diet, or stress levels that may contribute to this condition.

Another important aspect to consider is the possibility of a urinary tract infection. UTIs can cause frequent urination, urgency, and discomfort, even if the urine output is low. Symptoms may also include burning during urination, cloudy or foul-smelling urine, and sometimes fever or abdominal pain. Since you mentioned that your urine output is less than 100cc, it would be prudent to consult a healthcare provider for a urinalysis to rule out any infections.

Moreover, psychological factors such as anxiety can also manifest as frequent urination. Adolescents often face various pressures, whether academic, social, or familial, which can lead to increased anxiety levels. This anxiety can sometimes result in a heightened awareness of bodily sensations, including the need to urinate.

To address your symptoms, here are some recommendations:
1. Hydration: Ensure you are drinking enough water throughout the day, but try to limit fluid intake in the hours leading up to bedtime to reduce nocturia.

2. Dietary Adjustments: Incorporate more fiber into your diet to help alleviate constipation. Foods such as fruits, vegetables, whole grains, and legumes can promote regular bowel movements.

3. Bladder Diary: Keeping a record of your fluid intake, urination times, and volumes can help identify patterns and triggers for your symptoms. This information can be valuable for your healthcare provider.

4. Consult a Healthcare Provider: Given your symptoms, it would be wise to see a doctor. They can perform a thorough evaluation, including a physical examination and necessary tests, to determine the underlying cause of your frequent urination and constipation.

5. Stress Management: If you suspect that anxiety may be contributing to your symptoms, consider engaging in relaxation techniques such as deep breathing, mindfulness, or physical activities that you enjoy.

In conclusion, while frequent urination in adolescents can stem from various causes, the combination of your recent constipation and urinary symptoms suggests a need for further evaluation. It’s essential to address both the urinary and gastrointestinal symptoms to find a comprehensive solution. Don’t hesitate to reach out to a healthcare professional for personalized advice and treatment options.
