So insulin is the only option, and Type 2 diabetes, of course Insulin is the final one. Normally depends, depends on what is the blood sugar level when you first check if the blood sugar level upon first track is easily, more than 10 or even 15 or even 20. That's how you need insulin also straightaway because the pancreas is not working anymore. You mentioned the senior come in and the caregiver check, and it's like, Wow 15 or 20, definitely insulin. I'll straight away ask: are you on insulin already? They will say yes, you know, maybe they gradually move towards that, because the function of the pancreas may deteriorate one day by one day, so of course first commonly prescribed by a doctor is always Metformin. If you go to a government I think government hospital Pulau Pinang or even government hospitals, Glucophage is one of them, you know, Glucophage is brand of Metformin, Type 1 sorry, Type 2, first line, or nowadays there are newer drugs like Januvia. There are so many. So you see, normally for mild case, diabetes, the doctor would prescribe Metformin. And if we get worse or the diabetes is not managed well. Commonly the doctor will actually add on your medicine. So it could be one type , two type, three type or even four types, you know, slowly, slowly increase on those, maybe 500 mg, 850, 1000, or go to maximum dose I've seen cases where Metformin is prescribed until like two grams or even three grams, higher dose, But still diabetes cannot be managed. So at that time, doctor may add on things like second line, we call it, maybe you have heard of it Diamicron, Glipizide, they are so many.
