Self monitoring blood glucose refer to a practice for people diagnosed with diabetes to do home blood glucose testing.
Aids in dietary changes
The impact of food intake on blood sugar can be seen through two hours post meal blood glucose testing. According to the Diabetes UK (2019), this reflect the phrase of ‘Eat Your Meter’ which help patient to recognize the type and amount of foods that might significantly increase blood sugar level. Thus, patient can avoid the food that can lead to hyperglycaemia and subsequently motivates them towards healthy diet behaviors.
In order to maintain a good level of blood sugar, patient need to write down each food that had been consumed and their respective blood glucose level in a food diary.There are three important points that need to be included into food diary; blood glucose before meal, amount and type of food consumed, and blood glucose 2 hours post meal.
The pattern of fasting blood glucose level can be one of the indicator for health care team to determine the suitable medication. For instant, the medication that is beneficial to improve glucose output by liver will be provided by the health care team if patient’s fasting blood sugar is consistently high.
Besides, SMBG reading help people with diabetes who are on insulin to determine their insulin regimen wisely and help to avoid hypoglycaemia episodes. This practical is really beneficial particularly to the young children that had been diagnosed with Type1 diabetes as they might have difficulty to detect the symptoms of hypoglycaemia
Physical activity adjustment
Exercise or physical activity can give impact the blood glucose level by influencing the insulin concentrations and glucose uptake by skeletal muscle. In addition, blood glucose level after exercise will be affected by several factors including intensity and duration of exercise, insulin dose and blood glucose level prior to exercise. Thus, SMBG is a vital tool to diabetic patient in adjusting the appropriate physical activity for them.
For instant, people with diabetes may need extra carbohydrates and reduce the insulin dose if they would like to have an intense activity in order to prevent acute hypoglycaemia. However, this depends on the values of blood glucose level prior to exercise. Therefore, if blood glucose level is below 5mmol/l before exercise, patient is encouraged to take a small carbohydrate snack to increase the blood glucose level.
