Lately I've gained some unexplained weight. I haven't really had any changes in my eating levels. Also I've noticed stretch marks in my tummy area and on my breasts... :confused: I have no idea what to think is going on. Also I've been having problems with my normal activities. I work at a daycare, and run after toddlers all day. A few months ago I could do this with no problem, now I break out in cold sweats, get sick to my stomach, and feel tingling in my face and fingers, like I'm low on oxygen. This happens with almost any activity. I'm not sure what to think...any input would be appreciated. :)
Meh, possibly a heart condition. Unexplained gain in weight could mean you are building up fluid due to heart failure. Oxygen problems could occur when your heart can not pump adaquite blood to supply enough oxygen to your body.

Either way, your doctor is the best place to look for answers.
