Dr. Ramalakshmi emphasizes that dehydration in diabetics can trigger electrolyte imbalances and kidney issues. She advises two to three liters of water daily, along with buttermilk and controlled portions of watermelon. Avoid fruit juices and jaggery drinks, opting for fenugreek water and ragi malt to prevent fatigue and kidney injury.
