Dear doctor,

Recently, I was diagnosed with diabetes, and my blood sugar fasting was 231 mg/dL, and random was 271 mg/dL. I consulted a doctor, and he prescribed me Qosmet 500 mg/ 50mg twice a day and Amaryl 1 mg once in the morning. After a week, my sugar was under control, and blood sugar fasting was 93 mg/dL, and random was 111 mg/dL and 139 mg/dL. For three days, I was fine, but after that, I felt vertigo (dizziness). Kindly tell me why this is happening to me. Is it any side effect of the tablet I am taking or any other issue?



Welcome to

You should monitor your blood sugar twice a week, especially when you feel dizzy. Initially, with the start of medication, you may have some low blood sugar symptoms due to the first effect of medicines to treat diabetes. I suggest you buy a glucometer, check your blood glucose twice a week, and check your blood sugar whenever you have such kind of symptoms as dizziness, sweating, and irritability.
