Coconut water is a good choice â it's naturally hydrating with good
electrolytes, and the potassium in it is actually beneficial for blood pressure. One glass a day is fine. However, I'd avoid giving Glucose D regularly. Since your mother is on oral steroids, her blood
sugar may already be at risk, and Glucose D is essentially concentrated sugar which can spike glucose levels. For summer hydration, plain water, coconut water, or a low-sugar ORS is much better than Glucose D. Make sure she's drinking adequate water through the day and not waiting until she feels very thirsty.
