I'm a sickle cell pateient and i relly need to gain weight...any sugesstions?

Eat more: Gaining weight should not be difficult. You need to find out the calories in various foods and consume those foods which have high calories.Such foods include dairy products like milk, ice cream eggs and meats. Vegetables are low in calories so you can afford to reduce their quantity, which will allow to consume more milk products like yogurt, milk shakes/smoothies etc.
