Hi Mam, I had gone through your query and understood your concerns. Tiredness usually common in diabetics and some other clinical conditions like iron deficiency and electrolyte imbalance. You need to check for Hb%, serum electrolytes and get the evaluation done. Coming to vision, with age progressing, vision also decreases in some individual. In diabetics if sugar levels are not under control, then retina gets involved and reduces visibility. So you need to test refraction and retinal examination done. Hope this guides you. If you have additional questions please do not hesitate in writing to us. I will be happy to answer your queries. Thank you. Wishing you good health. Dr Phanindra Dulipala. Diabetologist.
