What is an ulcer?

  • In medical terms, an ulcer is defined as an exposed sore on the outer or inner surface of the body caused by an acute infection at the points of a break in the skin or the mucous membrane lining.
  • These are commonly manifested as single or aggregated lesions in different parts of the human body that cause severe pain and are in most cases incurable.
  • Such sores are mainly formed due to bacterial infections that lead to excessive erosion and damage of the epithelial tissues at the sites of infections.
  • In critical cases, ulcers may be manifested as pus-filled blisters on the inner linings of vital parts of the body.
