Definition. Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C).
The medical term is bromhidrosis. Occasional abnormal body odor may be a temporary effect of a metabolic change, such as fruity breath in diabetic ketoacidosis, but by far the most common cause of abnormal body odor is excessive perspiration or hyperhidrosis (overactive sweat glands).
Mouth and throat problems that can cause mouth odor include: 1  Throat or mouth infections, such as strep throat. 2  Dental problems, such as cavities. 3  Gum disease (periodontal disease), which may cause a metallic breath odor.  Tonsils with deep tunnels (crypts) that trap food 1  particles. Throat or mouth cancers.
