You are not the only one, almost 5 out of 10 people suffer from underarm or armpit smell. This is also known as a fish-like smell.  This is more common in summer. You know the sweat secreted by the body has no smell until bacteria grow on it.

Pathophysiology of underarm smell

Two types of sweat glands exist in your body. One is the Eccrine gland which secretes clear watery secretion on the body’s surface. Another one is the apocrine gland which secretes thick secretions on the body surface especially under covered body places e.g., underarms. When bacteria start growing on apocrine secretion then smell produces. Both of these glands become active after puberty.
