Is a blood sugar watch reliable

A blood glucose watch is a new, non-invasive, and painless blood glucose monitoring device that is easy to wear and can monitor blood glucose at any time. However, its detection results are not accurate compared to traditional fingertip blood glucose meters and are not very reliable.
A blood glucose watch detects glucose concentration in subcutaneous tissue fluid through electrochemical sensors and electroosmotic principles. There is a certain correlation between glucose concentration in tissue fluid and glucose concentration in blood, but there is a certain lag, and the two are not completely consistent. Therefore, the detection value of the blood glucose watch is not very accurate and further verification is needed.
Of course, the blood glucose watch also has certain advantages. Because of its non-invasive and painless characteristics, it is suitable for diabetes patients who need to measure blood glucose frequently, especially those who are afraid of using finger blood glucose meter. The blood glucose watch also has a certain role in monitoring blood glucose fluctuations over a period of time.
Patients need to pay attention that the blood glucose watch can not completely replace the traditional fingertip blood glucose meter, and clinical monitoring and management still need to focus on fingertip blood glucose meter, especially for patients diagnosed with diabetes soon, it is recommended to use the traditional fingertip blood glucose meter first. It is suggested that patients with diabetes should choose the most suitable blood glucose monitoring equipment under the guidance of doctors, rather than blindly purchase it.
In addition, in daily life, to control blood sugar fluctuations, it is recommended to eat more foods containing dietary fiber, such as various fresh vegetables and fruits, and a light diet to avoid consuming high calorie and high sugar foods. I also need to participate in some physical exercises, such as swimming, running, hiking, etc., which can help promote my physical health.
