Introduction
Under normal circumstances, if patients with hyperglycemia have well-controlled blood sugar levels, they can eat watermelon. However, if their blood sugar control is unstable, they should avoid consuming watermelon. If patients with hyperglycemia maintain good glycemic control and also regulate their intake properly when consuming watermelon, they can eat it in moderation. Watermelon contains a high amount of water and fiber, which can help promote digestion and metabolism.

Generally, if patients with hyperglycemia have good blood sugar control, they can eat watermelon. However, if their blood sugar levels are unstable, they should avoid eating watermelon. Detailed explanation is as follows:

If patients with high blood sugar maintain good glycemic control and manage their intake properly, they may consume watermelon in moderation. Watermelon contains a high amount of water and fiber, which helps promote digestion and metabolism. Additionally, it contains beneficial nutrients such as vitamin C and lycopene. However, watermelon also has a considerable sugar content, so patients with hyperglycemia should control their portion sizes and avoid excessive consumption.

If patients with high blood sugar experience unstable or continuously elevated blood glucose levels and have severe symptoms, it is not recommended to eat watermelon. Watermelon contains a large amount of sugar, especially glucose, fructose, and sucrose. These sugars are rapidly absorbed into the bloodstream after consumption, leading to an increase in blood glucose levels. Eating watermelon under such circumstances may cause a sharp rise in blood sugar, worsen the condition, and increase the risk of complications such as diabetic retinopathy, diabetic nephropathy, and diabetic neuropathy.

In daily life, managing blood sugar levels should also involve a comprehensive approach, including balanced dietary combinations, moderate physical activity, and regular sleep patterns, to ensure overall health.
