Frequent urination?

Hello, doctor.
I have multiple issues, and I'm back again with a problem of frequent urination.
Since the weather has turned cooler, I've suddenly noticed an increase in the frequency of urination.
Starting from Monday, I've felt a sense of heaviness in my abdomen and a strong urge to urinate.
During the day at work, I've been urinating approximately every two hours, and by the end of the workday, I've gone about five times (not including nighttime).
The volume each time varies between 100 to 300 mL.
By Wednesday, the frequency increased to ten times.
I visited a doctor, and they said that my urinalysis showed nothing significant, but my urine specific gravity was low at 1.005.
I explained the situation and mentioned that I had consumed a lot of water before the appointment.
The doctor said this could affect the specific gravity but did not prescribe any medication.
They advised me to keep a urinary diary for a week.
I started this yesterday morning, and including nighttime, I've been urinating about eleven to twelve times a day.
Should I be concerned about this? I will return to see the doctor next Wednesday for further evaluation.
Is this related to menopause? I had an abdominal ultrasound in September to monitor adrenal tumors and a left kidney tumor, and there hasn't been much change.
Am I just worrying myself? The doctor mentioned that I am not dehydrated and that I might be drinking too much water.
My current weight is around 38 to 39.5 kg, and I drink about 1500 mL of water a day.

Hello: The frequency of urination is closely related to fluid intake, as well as factors such as the nature of your work, stress, changes in weather, and dietary choices.
If you can maintain a more even fluid intake, and your urine color is a light yellow, it is generally not a concern.
Keeping a urination diary can be helpful, but since you can produce 100-300cc of urine, it should be fine.
Currently, you should focus on consuming water as evenly as possible, limit diuretic foods and beverages, and engage in moderate physical activity, such as walking for 20-30 minutes daily.
I understand that you have regular check-ups, so there is likely no need for excessive worry; sometimes, the body simply adjusts to seasonal changes and will return to normal.
As for how much fluid you need, if your urine is light in color, that is sufficient.
Additionally, some water content comes from food, and individuals who are less active may not sweat as much, so they do not need as much fluid as suggested online.
Regarding menopause, its effects on urology tend to be gradual and are not as pronounced as other menopausal symptoms, so you can observe the situation.
Wishing you good health.

More Info

Frequent urination, or polyuria, can be a concerning symptom that warrants careful evaluation, especially when it appears suddenly or is accompanied by other symptoms. Based on your description, it seems that you have been experiencing an increased frequency of urination, with episodes occurring approximately every two hours during the day and even more frequently at night. The fact that your urine specific gravity was low (1.005) suggests that your urine is quite dilute, which can be indicative of several underlying conditions.

One of the most common causes of frequent urination is increased fluid intake, which your doctor has already mentioned. If you are consuming a significant amount of fluids—around 1500 cc per day—it could lead to more frequent urination. However, it’s essential to consider other potential causes, especially since you mentioned a feeling of heaviness in your abdomen and the sudden onset of these symptoms.

Some possible causes of frequent urination include:
1. Diabetes Mellitus: Both type 1 and type 2 diabetes can lead to increased urination due to high blood sugar levels, which cause the kidneys to excrete more glucose and water. If you have not been screened for diabetes recently, it may be worth discussing this with your healthcare provider.

2. Diabetes Insipidus: This is a less common condition that results from a deficiency of the hormone vasopressin, leading to excessive urination and thirst. It is characterized by the production of large volumes of dilute urine.

3. Urinary Tract Infection (UTI): Although your urine tests did not indicate an infection, UTIs can cause frequent urination, urgency, and discomfort. Sometimes, the infection may not show up in standard tests, especially if it is localized or if you have recently started antibiotics.

4. Overactive Bladder: This condition is characterized by a sudden urge to urinate that may be difficult to control. It can occur without any underlying infection or other identifiable cause.

5. Hormonal Changes: You mentioned the possibility of this being related to menopause. Hormonal fluctuations can affect bladder function and lead to increased urinary frequency.

6. Medications: Certain medications, especially diuretics or those that affect fluid balance, can lead to increased urination.

Given that you have already started a urinary diary, this is an excellent step in tracking your symptoms. It can provide valuable information to your healthcare provider regarding your fluid intake, the volume of urine produced, and any patterns that may emerge.
As for your concerns about the adrenal tumor and kidney issues, it is essential to keep your healthcare provider informed about any changes in your symptoms. While the tumor may not have changed significantly, it is still crucial to monitor any new symptoms that arise.

In conclusion, while your doctor has suggested that increased fluid intake may be the cause of your frequent urination, it is essential to continue monitoring your symptoms and follow up with your healthcare provider. If your symptoms persist or worsen, further evaluation may be necessary, including blood tests to check for diabetes or other underlying conditions. It is also important to discuss any concerns you have regarding hormonal changes or the potential impact of your previous health issues on your current symptoms.
