Please do not worry, as these symptoms can be effectively managed. Your blood sugar levels indicate that voglibose alone is not sufficient. Your doctor will likely need to optimise your therapy, possibly by adding other oral medications like metformin or initiating insulin. The mild blurred vision can occur due to high blood sugar fluctuations, but you should get a dilated eye exam to be safe. Your gout, knee pain, and toe spasms require evaluation for uric acid levels and potential nerve changes (neuropathy). Please visit your physician promptly for a comprehensive check-up, HbA1c test, and personalised medication adjustments.
