Introduction
Under normal circumstances, when the blood glucose levels of patients with type 2 diabetes are relatively stable, they may consume watermelon in moderation. However, if blood glucose control is poor, watermelon is not recommended. Patients should take their medications on time and use drugs such as metformin hydrochloride tablets, gliclazide modified-release tablets, and repaglinide tablets as directed by a physician to manage their condition.
Generally, when the blood sugar levels of patients with type 2 diabetes are relatively stable, they may consume watermelon in moderation. However, if the patient's blood sugar control is poor, eating watermelon is not recommended. If abnormalities occur, timely medical attention is advised. Detailed explanations are as follows:
When the blood sugar levels of patients with type 2 diabetes are relatively stable, they may choose to consume watermelon in moderation between meals or after physical activity, while correspondingly reducing intake of other carbohydrates. At the same time, patients should monitor blood sugar changes after consuming watermelon to ensure there are no significant fluctuations.
When the blood sugar levels of patients with type 2 diabetes are unstable and fluctuating significantly, eating watermelon is not recommended. If a patient's fasting blood glucose exceeds 8.0 mmol/L or their postprandial blood glucose is higher than 11.9 mmol/L two hours after eating, consuming watermelon might further elevate blood sugar levels, worsen the condition, and increase the risk of acute diabetic complications.
Patients should take prescribed medications regularly and control their condition under a doctor's guidance using drugs such as metformin hydrochloride tablets, gliclazide modified-release tablets, and repaglinide tablets. Additionally, maintaining balanced nutrition and consuming more foods rich in dietary fiber, such as corn, millet, and oats, is recommended to help delay carbohydrate absorption.
