For some reason, diabetes mellitus has often been the subject of a lot of confusion. People tend to make assumptions. They think that if you have "diabetes mellitus" that you automatically have Type 2 diabetes. But in fact this is not the case. If you have diabetes mellitus, then you can have either Type 1 or Type 2 diabetes. So the next time you hear someone spouting about how diabetes mellitus is Type 2, you can set them straight!
People often think that diabetes mellitus means that if you have Type 1 diabetes then you will be on insulin and if you have diabetes mellitus Type 2 then you will not, but instead you will take medication. Yet people who have Type 2 diabetes may also end up having to take insulin if they cannot control their diabetes through medication and diet alone!
This means that there is no one standard profile for someone with diabetes mellitus. Perhaps the only profile that you can create is for someone with Type 1 diabetes. Someone with Type 1 diabetes is much more likely to have developed it before adolescence and they will be on insulin for life. It is the Type 2 diabetes that is much more diverse. You can have people who are borderline diabetic who can control their diabetes with diet alone. Then others with Type 2 diabetes will have a lot of medication to take. Then there will be others who have medication and insulin to control their diabetes.
Perhaps the important thing to remember when thinking about diabetes mellitus is that different people experience the condition in different ways. Just because you have been diagnosed with diabetes Type 2, this does not mean that you will have to be on insulin for the rest of your life, but similarly you should not assume that because you have Type 2 diabetes, you will be able to control it with medication alone.
