 Do we have to know the types of diabetes ( Gestational , type 1 and 2 ) in detail or just diabetes mellitus in general?

Last year or the year before they asked to describe osteoporisis, so this indicates that there is a chance they could ask about any three types of diabetes.
But if you think about it, why would they ask about gestational or type 1?
I'd suggest you stick to type 2 and diabetes mellitus in general.
As for cancer, for example, probably stick to colorectal cancer, but be mindful of the other kinds just in case.

Only diabetes mellitus is specified in the study design.

EDIT: In regard to the above, osteoporosis is also specified.

I think all you really need to know is that Type 1 diabetes is from birth and is a result of the body's inability to produce insulin due to the production of beta cells. Type 2 is developed, it is a result of the body's inability to produce and use insulin properly. Gestational (it's in the name) is just when a mother develops diabetes when she is pregnant due to hormonal changes and usually goes away after pregnancy.

Agreed with the above - I think it's wise to know a very brief outline of the three, the general gist of the difference between them, but it's hardly something you need to sit and rote learn or that they'll ask in any form of detail.

I guess that's my take on a lot of stuff not directly specified in the study design.  You don't need to sit and learn it in detail but having a general vague awareness protects you against curveball questions, as there's always one or two no one would expect.
