The common causes of cold skin surface are environmental factors, hypothyroidism, hypoglycemia and so on.
1. Environmental factors: when the patient is in a cold environment for a long time, the lack of warmth measures, excessive sweating will evaporate and absorb heat, thus appearing skin surface cool, is a normal physiological factor.
2. Hypothyroidism: subclinical hypothyroidism, mainly for the serum thyroid stimulating hormone level is elevated, but the thyroid hormone level is normal. It may result in underproduction of thyroid hormones, decreased basal metabolic rate, underproduction of heat and cold skin surface.
3. Hypoglycemia: When the body’s blood glucose is lower than the lower limit of normal value, it may cause the nervous system to lose its source of energy, leading to the suspension of metabolic activity of nerve cells, which leads to the symptoms of skin surface coolness.
When the patient appears skin surface cool for a long time without relief, should consult the doctor in time, under the guidance of professional doctors, clear diagnosis for treatment.
