Hi doctor,

I have observed that for the past three days, my sugar levels in the morning are increasing to the level of 160 mg/dL, and during the day, sugar levels are around the same range. Would you please suggest if I am getting diabetic, or is there any reason for my increased sugar levels in the morning? Currently, I am taking Telma for hypertension.



Welcome to

A fasting blood sugar level of 160 mg/dL is very high, suggesting you have diabetes. So please do an HbA1c test (glycated hemoglobin), giving you the three-month average of your blood sugar levels, and we can decide on your treatment. So please get back to me with the HbA1c result. Regards.

Hi doctor,

Thanks for the reply.

I have uploaded my HbA1c report, and it is 6.7 percent. Blood sugar is only high in the morning before breakfast, and gradually as time passes, it reduces to 110 mg/dL to 120 mg/dL during the day as I checked in the glucometer. I am only using Telma 20 mg for my blood pressure, and it is normal now. I am not taking any other medication for my sugar levels. I am also feeling heavy these days and quickly getting tired after household chores. Please suggest a diet and medication if required and please tell me if I can overcome without medication.

Thank you.



Welcome back to

Thank you for doing HbA1c promptly. Your HbA1c levels indicate you have diabetes (attachments removed to protect the patient's identity). Below 5.7 percent it is non-diabetic, 5.8 percent to 6.4 percent it is pre-diabetes, and above 6.5 percent it is diabetes. But I think you are recently having these high levels, so diet control will be enough along with exercise and walking. Are you taking a heavy dinner? At what time you have food?

The things you have to do is,

1. Completely avoid sugar, jaggery, sweets, root vegetables, and refined foods like white bread, noodles, pizza, etc.

2. Reduce fruit intake. You can take a limited quantity of fruits, but you have to reduce your food intake at that time.

3. You have to reduce your carbohydrate intakes like rice, wheat, and cereals.

4. Reduce fats and oil as much as possible.

5 . Take more protein-rich foods like pulses, egg whites, and lean meat (if you take nonvegetarian food). If you are a pure vegetarian, you can include pulses, skimmed milk, curd, or buttermilk (low fat). You can also take soya milk or soybean.

6 . Take dinner before 8 PM, and maybe if you sleep late, you can have a glass of milk or curd one hour before going to bed. Again, take a light dinner with fewer carbohydrates.

6 . Take plenty of green vegetables, leafy as well as others with more fiber. When you reduce carbohydrates, you will feel hungry, so you can take more vegetables to fill your stomach. You can consume fresh salads with cucumber, tomatoes, broccoli, cabbage, etc. You can take them raw.

7. Please walk for 50 minutes per day. Also, you can do some exercises, not very heavy. For example, you can practice yoga, dancing or skipping, anything in the form of exercise.

Please follow this for one month and get back to me with FBS (fasting blood sugar) and PPBS (postprandial blood sugar- two hours after food).

HbA1c we need to repeat only after six months. Are your thyroid function tests normal? If not done, please do that also.
