Why am I so cold after my weight loss surgery?
With less body fat and energy, you get cold faster—even if it's not very cold outside.
Bodyfat acts like a blanket for your body, making it difficult to lose heat. It keeps you very warm. However, after a weight loss surgery, you gradually lose this body fat. Your ""blanket"" becomes thinner, and your body can lose heat more easily.
Additionally, you can now eat less, so your body gets less food to convert into energy. Your body then conserves energy more efficiently. With less energy production, less heat is generated.
