Diabetes can be classified into three namely type 1, type 2, and gestational. A student applying for the course must keep in mind to have a keen interest and show patience to study the disease as it has many long-term effects and some of them are still being researched. Pediatric diabetology, geoenvironmental diabetology, and the concept of cardiometabolic risk are the recent discoveries and research interests in the course. The course can also be considered as a specialty of endocrinology.

The course deals with learnings of diabetes along with certain concepts of Chemical Engineering/It aims to inculcate the importance, details, types, and ways for the cure of diabetes. It is also about conducting a comprehensive study of the learning about the disease from the origin, its effects, and the intensity of different variants on people of different age groups. The course initially covers fundamentals about the classification, and diagnosis, and public health aspects of diabetes.

There are job options related to this course in the fields of pharmaceuticals as a diabetic practitioner who is involved in the prescription and management of patients with the condition. A candidate who completes the course can go into research which has a huge scope as it is a field where a cure has not been found yet. The qualified can also work in laboratories that help maintain the disease and can also work in health care centers as an endocrinology physician. As it is a disease that takes the life of a large group of people globally, a career in the fight against this disease would provide huge job satisfaction.
