Sweating or clamminess
The reduction of blood glucose levels leads to the activation of fight or flight response by the nervous system in the body. The triggering of the body’s stress response due to hypoglycemia produces adrenaline and norepinephrine in additional quantities which might lead to excessive sweating as well as trembling of the limbs. Sweating is one of the classic symptoms of hypoglycemia which might lead to coma or even death if the blood sugar levels drop down further. The skin starts turning clammy and cold in response to the low blood sugar levels. The moderate condition of hypoglycemia makes the affecting person nervous, sweaty and cold at the same time.
