Kidney Issues: Urination Patterns and Posture Effects

Kidney problems

Hello Doctor: My urine output is not very high, about 100 to 200 ml each time, and the color is yellow or dark yellow.
I feel the urge to urinate every 2 to 3 hours.
However, when I am half-reclining and half-sitting on my bed using my phone at night, the time between urges decreases to about every 30 minutes, and the urine color changes to light yellow and somewhat transparent, with a volume of 150 to 200 ml each time.
I haven't been drinking much water, and I also feel a bit uncomfortable in my back and sleepy.
A few months ago, urine tests showed no protein and normal values.
I do not have nocturia while sleeping, but my morning urine tends to be orange.
I would like to know if this situation could be related to my half-reclining position.
If I sit normally at my desk at night, I do not experience this frequent urination issue.
Is this related to my posture or could it indicate impaired kidney function?

1.
Urine color is not related to posture; it is recommended to visit a hospital for examination to rule out urinary system issues.
2.
Kidney function impairment is assessed by serum creatinine and glomerular filtration rate.
If there is no proteinuria and the values are normal, it does not indicate abnormal kidney function.

Understanding your kidney issues and urination patterns can be quite complex, especially considering the various factors that can influence urinary habits and kidney function. Based on your description, it seems that your urination frequency and volume vary significantly depending on your posture, which is an interesting observation that can indeed be related to both physiological and anatomical factors.

Firstly, the fact that you experience increased urgency and frequency of urination when in a semi-reclined position could be attributed to several reasons. When you are sitting or lying down, especially in a semi-reclined position, the pressure on your bladder can change. This change in pressure may stimulate the bladder more than when you are sitting upright at a desk. Additionally, the position of your body can affect the distribution of fluids in your body, potentially leading to increased urine production or a sensation of needing to urinate more frequently.

The color of your urine can also provide insights into your hydration status and kidney function. Yellow or dark yellow urine typically indicates that you may be slightly dehydrated, while pale yellow or clear urine suggests adequate hydration. The fact that your urine appears darker in the morning could be due to the concentration of urine overnight, as you are not consuming fluids while you sleep. This is a normal physiological response. However, if you notice persistent changes in urine color or consistency, it is always a good idea to consult with a healthcare professional.

Regarding your back discomfort and feelings of sleepiness, these symptoms could be related to various factors, including posture, muscle strain, or even kidney function. While your urine tests have shown no proteinuria and normal values, which is reassuring, it is essential to consider that kidney function can be influenced by many factors, including hydration, posture, and overall health.

If your symptoms persist or worsen, it may be beneficial to undergo further evaluation. This could include imaging studies or additional blood tests to assess kidney function more comprehensively. It is also important to maintain a healthy lifestyle, including adequate hydration, a balanced diet, and regular physical activity, which can all contribute to better kidney health.

In summary, your urinary patterns and symptoms may indeed be influenced by your posture, but they could also reflect underlying kidney function or hydration status. It is crucial to monitor these symptoms and discuss them with your healthcare provider, who can provide tailored advice and potential interventions based on your specific situation. Regular follow-ups and open communication with your healthcare team will help ensure that any changes in your condition are addressed promptly.
