Charting blood sugar levels enables more effective diabetes management, according to Healthline. Charting blood sugar allows a person to keep track of changes in its level, which may influence the course of his diabetes treatment, particularly if his blood sugar level is very high or very low.
For the majority of adults, healthy blood sugar levels are under 180 milligrams per deciliter within two hours of a meal, over 70 and under 130 milligrams per deciliter before a meal, a general A1C reading of 7 percent, and a fasting eAG reading of 154 milligrams per deciliter, Healthline reports. These levels may differ for pregnant women or adults with certain conditions. A level above 180 milligrams per deciliter is higher than recommended and may be dangerous, while a level lower than 50 milligrams per deciliter may be dangerously low. Individuals with hypoglycemic unawareness, who are likely to have a low blood sugar level but are not aware of the warning signs, may attempt to maintain higher levels.
Individuals charting their blood sugar levels should do so regularly several times a day and without skipping any times, Healthline stresses. Tracking blood sugar levels before and after meals is especially important as is noting other possible influences on blood sugar levels at the time. These include weather changes, infections and mild illnesses, and changes in the level of physical activity.
