WebMD and Healthline both provide blood sugar charts for diabetics, and Healthline also provides information on how to use the chart. Diabetics must chart their blood sugar levels throughout the day to manage their disease, explains Healthline.
Charting blood glucose levels helps diabetics to avoid hypoglycemia and hyperglycemia. Blood sugar levels can also help diabetics determine whether they need medication and can highlight the need to change treatment plans that are not working, according to Healthline. Diabetics can use printed charts, such as those made available for download at Healthline and WebMD, or use mobile apps that allow them to keep the same crucial records.
