Holding urine and drinking water inquiry?

Hello, doctor! Due to my work circumstances, I often have limited opportunities to use the restroom during working hours, which has made holding in urine for long periods and drinking insufficient water a regular habit.
I would like to ask the doctor: Can long-term retention of urine and insufficient water intake harm kidney function, potentially leading to the need for dialysis? What are the possible long-term consequences of these two bad habits? Thank you for your clarification!

Hello: If you drink less water, you can make up for it by drinking more during less busy times of the day.
It's advisable to limit water intake 2-3 hours before work.
Generally, normal urinary retention during certain periods should not affect kidney function, but it may weaken the bladder.
Therefore, if you experience any urinary symptoms, you should seek medical attention.
Most people have similar work schedules, where certain times are inconvenient for drinking water and using the restroom, but it's important to maintain normal hydration during other times of the day.
As for dialysis, blood tests should be done every six months, and if any abnormalities are detected, your doctor will notify you.
There's no need to be overly anxious.
Wishing you good health.

More Info

Long-term urine retention and inadequate hydration can indeed pose significant risks to kidney health. The kidneys play a crucial role in filtering waste products from the blood and maintaining fluid and electrolyte balance in the body. When urine is retained for extended periods, it can lead to several complications that may ultimately affect kidney function.

Risks of Long-Term Urine Retention
1. Increased Pressure in the Urinary Tract: When urine is held for too long, it can cause increased pressure in the bladder and urinary tract. This pressure can lead to bladder distension and may eventually affect the kidneys, potentially causing hydronephrosis (swelling of the kidney due to a build-up of urine).

2. Urinary Tract Infections (UTIs): Retaining urine can increase the risk of urinary tract infections. Bacteria can multiply in stagnant urine, leading to infections that may ascend to the kidneys, causing pyelonephritis, which is an infection of the kidney. Recurrent UTIs can lead to scarring of kidney tissue and impaired function over time.

3. Bladder Dysfunction: Chronic urine retention can lead to bladder overactivity or underactivity. This can result in a condition known as bladder dysfunction, where the bladder loses its ability to contract effectively, leading to further complications.

4. Kidney Damage: In severe cases, prolonged urine retention can lead to kidney damage. The increased pressure from the bladder can back up into the kidneys, causing them to swell and potentially leading to permanent damage if not addressed promptly.

Risks of Inadequate Hydration
1. Concentration of Urine: Insufficient fluid intake leads to concentrated urine, which can cause irritation of the urinary tract and increase the risk of kidney stones. Kidney stones can obstruct the urinary tract, leading to further complications, including hydronephrosis.

2. Decreased Kidney Function: Chronic dehydration can impair kidney function over time. The kidneys require adequate hydration to filter blood effectively. When dehydrated, the kidneys may not be able to perform their functions optimally, leading to a decline in overall kidney health.

3. Electrolyte Imbalance: Inadequate hydration can lead to imbalances in electrolytes such as sodium and potassium, which are critical for various bodily functions, including muscle contractions and nerve signaling. Severe imbalances can lead to serious health issues.

Long-Term Consequences
If these habits persist, they can lead to chronic kidney disease (CKD), which is characterized by a gradual loss of kidney function over time. In advanced stages, CKD can progress to end-stage renal disease (ESRD), requiring dialysis or kidney transplantation.

Recommendations
1. Regular Bathroom Breaks: It is essential to make time for regular bathroom breaks, even during work hours. This helps prevent urine retention and reduces the risk of urinary tract infections.

2. Adequate Hydration: Aim to drink enough fluids throughout the day. The general recommendation is to consume at least 8-10 cups of water daily, but individual needs may vary based on activity level, climate, and overall health.

3. Monitor Symptoms: Pay attention to any symptoms such as changes in urination patterns, pain during urination, or lower back pain, which may indicate kidney issues. If you experience these symptoms, consult a healthcare professional promptly.

4. Regular Check-Ups: Regular medical check-ups, including kidney function tests, can help monitor your kidney health and catch any potential issues early.

In conclusion, long-term urine retention and inadequate hydration can have serious implications for kidney health. By adopting healthier habits regarding urination and hydration, you can significantly reduce the risk of developing kidney-related complications. Always consult with a healthcare provider for personalized advice and recommendations based on your specific health needs.
