I've gained! - but is it water weight?

I gained 2 lbs! The first time I've gained anything in months and months! I'm so happy... but I'm worried maybe it's just water weight? How can I tell? I mean, if it is water weight I guess that's okay because I've been severely dehydrated quite frequently, once to the point of being hospitalized. But I just want to know how I can tell if it's REAL weight and not just water weight.

You'll be able to tell in a week or two's time.  If you keep eating a sufficient amount and it's still there next week and the week after then it's less likely to be water weight which is much more temporary.   Stay off the scales for a week now because weight will fluctuate daily.  Same time, same day, next week... that's when you'll know.  Good luck

As Jane has said, you'll be able to tell in a week or two. If you're not eating the minimum ideal of 2500 or 3000 (depending on your gender, and that's if you're doing no exercise; you'll need more if you work out) then you should aim to go up to that, but otherwise, find out in time! Congratulations on the gain either way.

I am confused (and frustrated) by these weight fluctuations.  My weight has fluctuated between 103.4 and 106.4 for several months now. I am 5'8" tall.  Every time I think my weight goes up I feel like I shouldn't add any more calories. I feel like I'm might be gaining and don't want to add any more calories.  Is that normal to fluctuate like that and should I still be adding more calories. My weight has not been over 106.4 lbs.for quite a while.  It's those days that start with the scale saying 106 that scare me from eating anymore. 

Any thoughts....Thanks!

It is normal for a body to fluctuate up to five pounds of water and food. If you are not gaining on your current intake you need to increase by 500. If you're not eating the suggested 2500 calories (for a woman) or 3000 calories (for a man) when sedentary already to gain weight, then you need to get there first, too.

If you are mentally fearful of increasing, you need to speak to a doctor about it.

It's likely water weight, but if you haven't weighed in a while and have been consistently working out, it could be muscle, too. 

I wouldn't freak out . . . You'll be able to tell in a little while if it's just water weight, which comes off relatively easily.  If it's not water weight, talk to a doctor and see what's going on.  It never hurts to check.

The OP is looking to GAIN. Please read the forum you are in before posting.
