Difference between Diabetes mellitus and Diabetes insipidus

Difference between Diabetes mellitus and Diabetes insipidus

Diabetes Mellitus and Diabetes Insipidus are two distinct medical conditions that, while sharing the name “diabetes,” differ significantly in their causes, mechanisms, and symptoms.

What is Diabetes mellitus?

Diabetes Mellitus is all about problems with blood sugar. It happens when your body either doesn’t make enough insulin or can’t use insulin properly. Insulin is a hormone that helps your body use sugar from food for energy.

What is Diabetes insipidus?

Diabetes Insipidus, on the other hand, is not about sugar at all. It’s a condition where your body has trouble managing water. People with this type of diabetes are constantly thirsty and pee a lot because their body isn’t able to keep water like it should.

While both conditions are called “diabetes” and share symptoms like frequent urination and excessive thirst, they’re very different. Diabetes Mellitus is about how your body manages sugar, and if left uncontrolled, it can cause serious complications.
