Question: Earlier (up to 10 months back), my FPS was always in the range of 75 to 80. Last month the FPS value shown 140 and today I retested. Then FPS is 119 and PPS is 109. Why FPS is higher than PPS. I have not consulted any doctor for this. Whether I'm diabetic.. Pls suggest

Brief Answer:
Prediabetes or Diabetes.

Detailed Answer:
Hi,

Thanks for your question.
Noted your concern.

Fasting blood glucose of 140 (>125mg/dl) denote diabetes.
While 119 denote Impaired Fasting Glucose (IFG) ie. Prediabetes.

Type 2 Diabetes is due to insulin resistance.

Fasting blood sugar depends on Hepatic glucose output (Glucose produced by liver to meet body's glucose requirement).

Postprandial blood glucose depends on intake of glucose in food.

Insulin resistance at liver leads to raised fasting glucose level.
Insulin resistance at muscles and adipose tissues (fat) (called as peripheral tissues) leads to raised postprandial blood glucose level.

When insulin resistance at liver is more than peripheral tissues, fasting blood glucose level is more than postprandial blood glucose level.

In such case I may suggest OGTT (Oral Glucose Tolerance Test) and HbA1c. Depending upon it further treatment like diet, exercise, medications can be advised.
Also If the diabetes or prediabetes is confirmed there may be need for treatment for your abnormal Lipid profile.

Hope this helps you.

Dr. Abhay Mali.
