Your diabetes is poorly managed and requires greater care if your HbA1c is 9 percent. Instead of cutting back on treatment on your own, see your doctor to modify the timing, dosage, or add a different medication if the morning dose makes you feel dizzy.

Weight gain in diabetes can happen because of insulin resistance, reduced activity, overeating, stress, poor sleep, or medicines that increase appetite. A post-meal sugar level around 160-180 suggests that blood glucose is improving partially but may still need better control through diet, exercise, or adjustment of treatment. Metformin usually helps with insulin resistance and is less likely to cause weight gain compared to some other diabetes medicines. Some newer diabetes medicines may help both blood sugar control and weight reduction in suitable patients. Doctors sometimes prescribe medicines from the SGLT2 inhibitor or GLP-1 receptor agonist groups because they may support modest weight loss along with glucose improvement. However, the right choice depends on kidney function, heart health, current weight, eating habits, and overall diabetes control. Regular walking, reducing sugary foods, improving sleep, and portion control also strongly influence post-meal sugars. Frequent urination, sudden weight loss, very high sugars, or dizziness should be reviewed carefully during treatment changes.
