# Reactive Hypoglycemia in Patients Prior to Cataract Surgery: A Case Series

## TL;DR

This paper reports five cases of reactive hypoglycemia in non-diabetic patients before cataract surgery.

## Contribution

The study highlights reactive hypoglycemia as a potential issue in pre-surgery patients, even in non-diabetic individuals.

## Key findings

- Five non-diabetic patients showed reactive hypoglycemia symptoms before cataract surgery.
- Symptoms included sweating, palpitations, and anxiety, typical of hypoglycemia.
- The cases occurred in patients aged 52-78 years between 2019 and 2023.

## Abstract

Cataract surgery is one of the most frequently performed surgical procedures and is often performed under topical anesthesia in conscious patients. Sweating, palpitations, and anxiety may be seen in patients about to undergo surgery. However, these are typical adrenergic symptoms of hypoglycemia and should be further investigated if occurring before surgery. Here, we report five cases of postprandial or reactive hypoglycemia observed in hospital settings just before conducting cataract surgeries in non-diabetic 52-78-year-old patients from 2019 to 2023.
