What cause low body temp.?
Answers:
There really are no significant diseases which head to hypothermia. The most common lead to of hypothermia is exposure to cold. This is usually a secondary event from some other entity. Mental retardation, alcohol or drug intoxication, dementia, injury that prevents a forgiving from getting inside: ie. hip injuries, stroke.
Metabolically, hypoglycemia (which decreases metabolism by depleting metabolic fuel availability) can organize to hypothermia. This is almost always subsidiary to inappropriate insulin use in a diabetic.
I hoped this help some, this can be somewhat complicated without a correct understanding of physiology.
