The most potent risk factor in the development of adenoiditis is being a young child. Other risk factors include immuno-deficiencies, living in an urban environment with more exposure to viruses or bacteria and usage of immuno-suppressant drugs.

Risk factors

Risk factors for adenoiditis involve increasing the risk of invasion by pathogenic viruses or bacteria.[1][2][3]

  • Living or working in close proximity to children
  • Living in an urban environment with more exposure to viruses or bacteria
  • Young child or elderly adult
  • Immunocompromised
  • Living or working in close proximity to airborne pollutants, such as smoke
  • Living in colder climates[4]
  • Excessive and prolonged use of corticosteroids
  • Obesity or overweight[5]
  • Living with someone who suffers the disease
