<p>I picked up a few pounds living in the dorm my first year away from home. I kept thinking it was the dryer that was shrinking my clothes (seriously), since we had only clothesline-dried clothes at home. When I came home for the summer, mom just said one sentence to me, “You look very “healthy;” lose some weight.” She debunked my dryer-shrinking theory, and I set about & promptly lost the weight over the summer by cutting out snacks, junk food and sugar, as well as having a very active summer watching kids at the summer recreational program.</p>
<p>I agree that if it’s a recent issue that your D has had, you can offer her a complete physical, including check on thyroid function & possible health issues that may be affecting her weight like those mentioned by others above. Thyroid function CAN affect weight as well, tho it is a less common issue in young folks.</p>
