Q. Dr. I don’t understand why sometimes my daughter feels weak (she’s very slim) even when she eats a lot. Could it be the lack of any vitamin? Could you please advise me on what I should give her to eat? Thank you so much.
A. Weakness can be caused by numerous issues. It’s probably best to talk with your family doctor so they can confirm that she is not anemic or ill. Also make sure that your daughter is getting adequate sleep, a balanced diet with lots of fruits and vegetables, participating in daily exercise, limiting caffeine, and drinking plenty of water to increase energy and prevent muscle fatigue.
