🩸 Understanding Blood Glucose Levels
Blood glucose is the amount of glucose present in the bloodstream. Glucose provides energy for the body's cells, and blood glucose levels can change throughout the day.
The timing of a blood glucose test matters. A fasting reading is generally taken after not eating for a period of time, while a post-meal reading may be checked after eating. Random readings can be taken at different times.
Food, physical activity, sleep, stress, illness, medication, hydration, and other factors may affect glucose readings.
A single home blood glucose reading does not by itself confirm or rule out diabetes. Repeated or concerning readings should be discussed with a qualified healthcare professional.
📋 What Can Affect a Reading?
Meals and carbohydrate intake can influence blood glucose.
Activity can affect blood glucose before and after exercise.
Stress hormones may temporarily influence blood glucose.
Some medicines and illnesses may change blood glucose readings.
