A blood sugar level of around 350 is quite high and suggests that your diabetes is not well controlled at the moment. Glucoryl-M2 may not be giving enough control right now, but changing directly to Metpride 2 on your own may not be the safest solution. High sugar levels like this can happen because of the progression of diabetes, irregular diet, infections, stress, missed medicines, poor sleep, or reduced response to the current treatment over time. A proper medical review is important because your doctor may need to check HbA1c, kidney function, diet pattern, weight, and daily sugar readings before deciding whether the medicine should be changed, the dose adjusted, or another treatment added. Sometimes, very high sugar levels may require stronger treatment for a period of time to avoid complications. Reducing sweets, sugary drinks, bakery foods, and overeating at night may help improve control. Regular walking, proper hydration, fixed meal timings, and taking medicines regularly can also support a better sugar balance naturally. Seek medical advice soon if you develop excessive thirst, blurred vision, vomiting, weight loss, severe weakness, or frequent urination along with very high sugar levels.
