My son dropped about 25 pounRAB his first year at college. He didn't like the food or the cafeteria and had to walk everywhere around campus....a first for him. He gained it back by graduation when he got into a dorm where he could cook for himself. And then he started to cook for the girls in the dorm and became a real favorite of the ladies.
Don't go interfering. He has to figure this one out by himself, mom. It's not like he's sick, just thin. And he will resent you for interfering in his college life. He sees himself as a man now, not a little kid in grade school who's mommy has to bail him out. And trust me, he will see it that way.
My son got into a car accident the first weekend he came home from college and I got way too involved making sure he got his physical therapy and saw the doctor when needed. He was so angry with me, he barely came home during his sophomore year. Had to prove he was old enough to take care of himself. Harder on me than him!
But by his junior year, he was doing really well. Had a girlfriend and grades were good and he was far more cheerful and back to his old self. It really is all about growing up, not just learning from books.
Your son may be hitting the books and not like the food and doing a lot of physical stuff you don't know about. But if he gets hungry enough, he'll eat. Don't send him healthy food...send him the junk he likes. I think my son lived on peanut butter that freshman year. College kiRAB go to cheap places to eat like McDonalRAB...they can talk and socialize and eat "comfort junk". Consider some gift carRAB to the local handouts.
As for roommates, he'll live and then he can change his roommate for next year. My son's 2 roommates got along with each other and not him and he was so glad he could go elsewhere as a sophomore. We all need to learn how to get along with people we don't like. Great experience for when you have a boss you don't like.
Freshman year is all about growing up and becoming an adult. He neeRAB to figure this one out for himself. Unless he is sick, don't get involved. Just be supportive and send money and comfort food. Let him come to you if he wants to. It's all part of growing up.

PS....that girlfriend my son had as a junior is now his wife of 5 years and they are expecting their 2 child in July. They went to grad school together and now have great jobs, a new house and the cutest 3 year old in the world! But then again, I might be a tad biased. A bad start at college can turn into a good thing!
