5 Key Takeaways

• 1

  Gastrectomy is associated with a higher long-term risk of developing dry eye disease (DED) according to a Korean cohort study.

• 2

  The study analyzed over 5,400 gastrectomy patients and nearly 22,000 matched controls to assess ocular surface health.

• 3

  Total gastrectomy significantly increased DED risk with an adjusted hazard ratio of 1.40, especially in older males and lower-income groups.

• 4

  Colectomy did not show an increased risk of DED, indicating the specific impact of upper GI tract alterations on ocular health.

• 5

  The findings suggest that post-gastrectomy patients require closer monitoring for dry eye symptoms and nutritional assessments.
