Hyperosmolar coma is a rare but serious condition in which the brain cells are dehydrated due to high sodium or sugar in the blood. For people with excessive water loss or high blood sugar, hypertonic coma can occur and should be promptly treated with fluids to lower the sodium or blood sugar. For people with hyperosmolar coma, they should eat more foods rich in protein and should pay attention to timely supplementation of vitamins and other minerals, and can eat more high-calorie, easily digestible foods such as eggs, apples, lean meat, soy products, and seafood.
