Can you have both diabetes mellitus and insipidus?

Yes, it is possible to have both diabetes mellitus and insipidus. Diabetes mellitus is a disorder of the pancreas that results in high blood sugar levels, while diabetes insipidus is a disorder of the kidneys that leads to excessive urination and dehydration. While these conditions are usually unrelated, it is possible for someone to have both at the same time. This can cause additional complications and require more intensive treatment.
