Patient's Query

Hi doctor,

I have type 2 diabetes. I am taking Humalog Insulin 1 unit, three times a day. Before a week, I checked my blood sugar level. It is found to be high in the morning and it was 189 mg/dL to 252 mg/dL. Before lunch, it was 216 mg/dL, I went to work and did my job. My blood sugar had no changes at supper and it was 180 mg/dL. After supper, it went down to 72 mg/dL. Why do I have this problem? I was sick for a week. After this, I have changes in my blood sugar level and how to lower it. My bladder seems to be sore when my blood sugar levels are high. I am drinking lots of water to avoid dehydration.

Hello,

Welcome to icliniq.com.

Thanks for the query. I have gone through your problem. You are only on Insulin Humalog (Insulin Lispro Injection), is that true? Do you take any oral antidiabetic medications? The Insulin units that you have mentioned "1 unit 3 times a day" Is it correct? Because 1 unit is not right. Do you mean that the fasting blood level is high? If so, then the blood glucose is too high in your case. Because ideally, FBG (fasting blood glucose) should be less than 99 mg/dL. Postprandial (PP) should be 148 mg/dL to 170 mg/dL. This means that your glucose level is not under control. You have not mentioned about HbA1c percentage. It gives clear information about your glucose control for the last three months. It should be less than 6.5 percent for the people under the age of 60 years and less than 7 percent for the people above 60 years. A glucose level of 72 mg/dL is too low. Low blood glucose level is a condition below 60 mg or so. In this situation, it is necessary to look at the dietary pattern, extent of exercise taken and the medication followed. There is a need to correct the fasting blood glucose first and then to care of postprandial glucose level. So, please revert back with the necessary details. Thank you.
