During treatment, the body is under greater stress, and proper hydration becomes essential for maintaining health. Treatment side effects such as dry mouth, nausea, vomiting, diarrhea, or constipation can increase the risk of dehydration. Chemotherapy and radiotherapy may also affect electrolyte balance. Inadequate hydration may cause muscle cramps, dizziness, or even irregular heartbeat.
Therefore, in addition to drinking enough water, choosing the right types of beverages and hydration methods is especially important for patients undergoing treatment.
