Okay, this is a little weird but I've noticed that after I eat my body temperature always feels like it shoots down. My fingers and toes get ice cold and the bottom of my nail bed turns a little purple. I'm a 22 year old female, 5'3'', around 115 lbs. eating 1300 calories a day (I really try to eat nutritionally dense foods only), exercising for half an hour 3-4 times a week if that helps anyone make the situation clearer.
Any ideas as to what's happening to me?
After you eat, your body shunts a lot of your blood to your intestines to help with digestion and absorption of the nutrients. It has to take that blood from somewhere, so your hands and feet get cold from the reduced circulation. I don't think it's anything to worry about, put on a sweater, walk around, and hold a cup of warm tea in your hands.
this happens to me a lot. I used to figure it was just me, but eventually I was finding myself cold all the time and while I've always had somewhat poor circulation, I ended up deciding I was also suffering from decreased metabolism. so, while the cold-after-eating experience can normal, (as explained above), you might want to keep your eye on your intake and activity and perhaps try eating a little more.. see how it feels.. if eating more you feel warmer or more like your metabolism has revved up and there's an internal furnace burning away, it might suggest the cold is a sign of caloric deficiency..
if it continues and isn't too problematic, I wouldn't worry to much about it, provided you're healthy in every other way..
