it is difficult to say how many calories she needs because i don't know her height weight or which illnesses she has. some illnesses increase metabolic rate even when a person isn't active. this webmd calculator can give you an idea of her general caloric needs. <link> but i recommend seeing a registered dietitian to better assess her calorie/nutrient needs and provide nutrition recommendations. some dietitians can visit people at their home so ask her doctor for a referral. otherwise go to eatright. org to find a dietitian near you.
