I'm a bit confused about my blood glucose levels. My fasting sugar came out higher than my reading two hours after eating. It was 155 fasting and 139 after a meal. At one point, my fasting level was 200, and a few days later, it dropped to 155. Why would my fasting sugar be higher than after a meal? Is this something to worry about?

It is not uncommon for blood glucose levels to be higher in the morning (fasting) compared to after a meal. This is due to the dawn phenomenon, where hormones released in the early morning hours cause blood sugar levels to rise. Additionally, if you had a high-carbohydrate meal the night before, it can also contribute to higher fasting blood sugar levels. To help manage your blood sugar levels, you can consider taking Metformin. It helps to improve insulin sensitivity and lower blood sugar levels. However, it is important to consult with your healthcare provider for proper evaluation and management.

I'm a bit concerned about my mom who is 52. Her name is Gayatri Singh. She has blood pressure but isn't diabetic. The doctor said her blood pressure is normal, but when we did a fasting sugar test at home, it was 162. What does this mean? Could it be that she might have diabetes? I would really appreciate some guidance on this.

A fasting blood sugar level of 162 mgdL is higher than the normal range (70-99 mgdL) and indicates impaired fasting glucose, a precursor to diabetes; given your mother's age, blood pressure history, and non-diabetic status, it's essential to consult her doctor for further evaluation, including a confirmatory fasting blood sugar test, oral glucose tolerance test (OGTT), or HbA1c test, to determine if she has developed diabetes or prediabetes, and to discuss lifestyle modifications and potential medication to manage her blood sugar levels
