Area of Science:

  • Nutrition Science
  • Gastroenterology
  • Ophthalmology

Background:

  • Vitamin A deficiency is uncommon in developed nations.
  • Bariatric surgery, particularly malabsorptive procedures like biliopancreatic diversion, is a risk factor for vitamin A deficiency.
  • Clinical vitamin A deficiency can manifest with significant ocular and dermatological symptoms.

Observation:

  • This article presents a case of clinical vitamin A deficiency after gastric bypass surgery.
  • The patient exhibited characteristic ocular and cutaneous manifestations.
  • A review of existing literature on this complication was conducted.

Findings:

  • Gastric bypass surgery can lead to vitamin A deficiency, even in developed countries.
  • Ocular and skin symptoms are key indicators of this deficiency.
  • Early recognition and management are crucial to prevent severe complications.

Implications:

  • Healthcare providers should consider vitamin A deficiency in patients with a history of bariatric surgery presenting with relevant symptoms.
  • Routine monitoring and supplementation may be necessary for at-risk patients.
  • Further research into optimal prevention and management strategies is warranted.
