                                Plasma, which makes up about 55% of your blood volume, is 90% water, meaning a donation can cause temporary dehydration and an electrolyte imbalance. The best thing to drink after giving plasma is a combination of plain water and electrolyte-rich beverages to help your body rehydrate and recover efficiently. Proper fluid intake is key to minimizing side effects like dizziness and fatigue.
