Fever in Elderly

Common causes of fever in elderly and what you should know.

Common Causes

  • Urinary tract infections (UTIs) — UTIs may cause fever in older adults, sometimes without typical burning pain due to milder symptoms (NIH).
  • Pneumonia — Lung infections might trigger fever, but elderly people could have lower fevers despite serious illness (CDC).
  • Weakened immune system from age or conditions — Age-related changes may make infections like flu cause fever more easily (Mayo Clinic).
  • Medications — Polypharmacy in seniors could lead to drug-induced fevers in some cases (NIH).
  • Underlying chronic diseases like diabetes — Conditions that impair immunity might result in fever from minor infections (CDC).
