Nearly half of newly diagnosed cancer patients receive radiotherapy. While radiotherapy destroys malignant cells, it also affects normal surrounding cells. Acute radiotherapy side effects include: fatigue, nausea, diarrhea, dry mouth, loss of appetite, hair loss, sore skin, and depression. The side effects are associated with increased oxidative stress and inflammation due to the generation of ROS during radiotherapy.
The consumption of hydrogen-rich water for 6 weeks reduced reactive oxygen metabolites in the blood and maintained blood oxidation potential. QOL scores during radiotherapy were significantly improved in patients treated with hydrogen-rich water compared to patients receiving placebo water.
Molecular hydrogen protects healthy tissue/cells from anticancer drugs and has been shown through studies to have a protective effect against chemotherapy drugs. Hydrogen has potential for improving the quality of life of patients during chemotherapy by efficiently mitigating the side effects of cisplatin.”
