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).
Other Causes. Some foods and medications can affect body odor. Hot beverages and spicy foods can cause sweating, and when combined with dirt and bacteria, this causes or exacerbates body odor. Some foods, such as garlic, are also secreted through pores. When these are combined with sweat, body odor results.
