What is the primary difference between primary diabetes mellitus and secondary diabetes mellitus

Answer 1

Type 1 Diabetes Mellitus is an autoimmune disease in which your body produces antibodies that attack your pancreas(beta-pancreatic cells) where you produce and secrete insulin. If you do not have insulin the cells in your body cannot absorb glucose and you will have high blood glucose levels. Hence, you treat Type 1 Diabetes Mellitus with insulin.

Type 2 Diabetes Mellitus (simplified) is when your insulin receptors on your cells become insulin resistant. This can be due to numerous factors such as genetics, diet, weight etc. It is harder to treat type II diabetes because giving insulin does not help. There are medications such as metformin that are used to help decrease the insulin resistance(increase insulin sensitivity) of the insulin receptors on cells

Answer 2

So by Primary and Secondary Diabetes, I assume you mean to say Type I and Type II.

1. Type I
2. Age < 30y onset usually (but possible older than that)
3. Lack of insulin production by pancreas, which is why insulin is main treatment (various types of insulin depending on how long you need it to act)
4. Type II
5. Age > 30y onset usually
6. Insulin is produced by pancreas, but your cells can be resisted to it
7. Resistance leads to more insulin production and hypertrophy of pancreas. Also hyperglycemia state. Therefore the main treatment is usually to have oral hypoglycemic medications like metformin (first line) and then the others like Glipizide to allow for insulin sensitivity rather than resistance.

Hope this helps. If there is anything in specific you'd like me to clarify, then let me know.
