Can dehydration cause blood in urine?

In general, mild dehydration does not directly cause blood in the urine (hematuria). However, extreme and prolonged dehydration can potentially lead to various complications and health issues in the body, and in some cases, it may increase the risk of urinary tract infections (UTIs). UTIs can cause inflammation and irritation of the urinary tract, including the bladder and kidneys, which can result in hematuria. Severe dehydration can also affect kidney function and cause damage to the kidneys, although this scenario is generally rare. Nonetheless, it's important to maintain adequate hydration to support overall health, including urinary tract health and proper kidney function. If you notice blood in your urine and are concerned about potential underlying medical conditions, it's crucial to consult a healthcare professional for evaluation and personalized medical advice.
