Introduction
Patients with type 2 diabetes whose condition is well-controlled—through standardized medication use and appropriate dietary management—may consume watermelon in moderation. However, since watermelon is relatively high in sugar content, intake should be limited. Conversely, patients with poorly controlled blood glucose levels—manifesting severe symptoms such as polyuria, polydipsia, and polyphagia—or those who have already developed complications are generally advised to avoid eating watermelon.

Patients with type 2 diabetes can usually eat watermelon when their condition is clinically stable, but only in moderation. However, if blood glucose levels are unstable, they should generally avoid eating watermelon.

1. Can eat watermelon

Diabetes can be classified into two types based on disease severity: type 1 and type 2 diabetes, with symptoms of type 2 diabetes typically being more pronounced. Patients usually need to take antidiabetic medications under medical guidance, such as acarbose, metformin, or insulin glargine, to manage their condition. When type 2 diabetic patients maintain a stable condition through proper medication and balanced diet, they may generally consume watermelon. However, since watermelon is relatively high in sugar, it should be eaten in moderation to avoid affecting blood glucose stability.

2. Should not eat watermelon

Type 2 diabetic patients whose blood glucose is poorly controlled and who experience severe symptoms such as frequent urination, excessive thirst, and increased appetite, or those who have already developed complications such as ketoacidosis or diabetic retinopathy, should generally avoid eating watermelon. During this stage of the disease, strict limitation of sugar intake is required, and the diet should primarily consist of sugar-free foods.
