Does eating watermelon raise blood sugar quickly?

Whether eating watermelon raises blood sugar quickly depends on the amount consumed and an individual's specific health condition.

Watermelon is a low-calorie fruit, but it has a relatively high sugar content. For healthy individuals, eating watermelon generally does not cause a rapid increase in blood glucose, as normal insulin regulation is present. However, for people with high blood sugar or diabetes, consuming a small amount of watermelon at one time usually has minimal impact on blood glucose levels. Nevertheless, eating excessive amounts of watermelon in a single sitting may lead to a rapid rise in blood sugar. It could also trigger complications such as ketoacidosis, causing symptoms like nausea, vomiting, abdominal pain, and headache. In severe cases, it may result in confusion, diminished reflexes, coma, or shock.

When such acute complications occur, prompt treatment is essential, including fluid replacement and intravenous administration of low-dose insulin to maintain electrolyte and fluid balance. Additionally, in daily life, individuals should limit intake of high-sugar fruits like watermelon. Without timely treatment, the condition may worsen and potentially threaten the patient's life.
