My dad is 54 years old ,he has diabetes for quite some time and due to job transfer, he changed to another place, he used to have only hotel food. And suddenly sugar levels have reached around 300 Units and he admitted in hospital and gave proper medication to take the situation in control, And even after that he was feeling so weak and used to get tired even after a small work. I need my dad to be healthy and active. What treatment should I refer him for getting a quick recovery?
