Is drinking more water helpful for urinary tract infections?

Urinary tract infection (UTI) is an inflammation caused by bacterial invasion into parts of the urinary system, such as the urethra, bladder, or kidneys. Common symptoms include frequent urination, urgency, and painful urination. Drinking more water is acceptable for UTIs, for the following reasons:

1. Flushing effect: Increased water intake promotes urine production and more frequent urination, helping to flush bacteria out of the urinary tract, reducing the time bacteria remain in the urinary system, thus lowering the risk of infection.

2. Dilution of urine: Adequate water intake helps maintain diluted urine, lowering the concentration of harmful substances in the urine, reducing irritation to the urinary tract, and helping to alleviate discomfort such as painful urination and urgency.

3. Promotion of metabolism: Drinking more water also promotes metabolic activity in the body, aids in regulating immune system function, and enhances the body's resistance to infection. Increasing water intake can improve overall blood circulation, including in the urinary system, which is beneficial for the resolution of inflammation and tissue repair.

4. Water intake: The daily water intake should be at least 2000 milliliters, and urination should occur every 2–3 hours.
