Knowing the diabetic person’s history and treatment duration is critical to understanding the abnormality. A higher postprandial blood glucose (PPBS) level suggests that your liver does not stop producing sugar after a meal and stores it in the form of glycogen. 

• Lantus is a long-acting insulin analogue that improves glycemic control. 
• Metformin and Janumet XR CP both decrease the production and absorption of sugar in the body so that it can utilise glucose more efficiently. 
• Voglibose controls blood glucose levels after meals by stopping the action of digestive enzymes that break down complex carbohydrates into simple sugars.

Postprandial sugar levels are high and need adjustment of insulin doses by a diabetologist.. Some healthy lifestyle tips to manage blood glucose levels are as follows:

• Eat balanced meals high in proteins and dietary fibres at the proper time.
• Increase your intake of high fibre food like whole grains, fruits and vegetables.
• Avoid eating processed carbohydrates and sugary foods, especially on an empty stomach.
• Exercise regularly.
• Monitor blood glucose levels and go for regular checkups with your doctor.

It is advisable to seek a medical evaluation with your diabetologist before changing your current medication.
