There are a few reasons.
1. Pre-diabetes can have such results which means you are more prone to get diabetes. Increased PPBS (postprandial blood sugar) means your pancreas is working very hard to reduce your sugar. It is overworking where it will deplanes beta cells in pancreas soon (beta cells present in the pancreas secrete insulin to maintain blood sugar).
2. Wrong blood report, take the report in a NABL (national accreditation board for testing and calibration laboratories) lab. Regular exercise and diet will help you. Meet a nutritionist and get a diet chart. Get a personal fitness trainer.
If these are not working to reduce your weight, then we can think of blood investigation and medical treatment.
