People living with diabetes have problems converting the glucose produced from the breakdown of the food they eat into energy for their body. This disorder is a result of impaired production of a hormone called insulin, which moves the glucose from the blood and into their cells.
Management of blood sugar (or glucose) levels during mealtimes is important. If blood sugar levels are not properly managed after meals, people living with diabetes will experience elevated blood sugar levels, also know as post-meal hyperglycaemia.
Prevention of high blood sugar or hyperglycaemia is vital because it can have a negative impact on the health and wellbeing of people living with diabetes.
See our list of five things you should know about managing diabetes at mealtimes:
1. PPG, FPG, and HbA1c are really important!
Measuring the following three elements of your blood sugar can help you get an overall picture of how well you are controlling it:
2. Uncontrolled blood sugar after meals leads to hyperglycaemia
High blood sugar after meals (or post-meal hyperglycaemia) is when your blood sugar levels typically go above 11.0 mmol/L (200 mg/dl) 2 hours after meals.
3. High blood sugar can result in short-term health complications...
High blood sugar levels (hyperglycaemia) can cause unpleasant short-term physical symptoms, such as:
4. ...and long-term health complications
If your blood sugar levels stay high for extended periods, long-term health issues can occur. For example, consistently high blood sugar levels after meals can lead to high HbA1c levels. Over the long-term, these high HbA1c levels can increase your risk of the following complications:
5. Mealtime insulins can help to control blood sugar levels after eating
To manage blood sugar levels after eating, rapid-acting insulin at
mealtimes (also known as a mealtime insulin or a bolus insulin) can be
used, which aims to mimic the release and response of insulin from a
healthy pancreas. Use of mealtme insulins can effectively control
blood sugar after meals and avoid high blood sugar levels (or
