Why is hydration crucial during cancer treatment?

Hydration is crucial during cancer treatment primarily because it helps to prevent dehydration and supports kidney function, especially during chemotherapy. Chemotherapy drugs can be nephrotoxic, meaning they have the potential to damage the kidneys. Adequate hydration helps dilute these medications in the body and flush them out, reducing the risk of toxicity and kidney damage. Additionally, proper hydration can mitigate some side effects of treatment, such as nausea and fatigue, and ensures that vital organs, including the kidneys, can function optimally throughout the treatment process.

While improving circulation and boosting energy levels are important aspects of overall patient health, they are secondary to the critical function of hydration in protecting kidney health and preventing dehydration during the intense periods of oncological treatment.
