Yes, a BDS student can pursue an MD in Physiology, but it depends on the eligibility rules of each university.

In most medical colleges in India, MD Physiology is offered mainly to MBBS graduates because it is a clinical/para-clinical postgraduate degree under the MD/MS system. However, some universities and institutes allow BDS graduates to apply for non-clinical MD courses such as Physiology, Anatomy, and Biochemistry. The availability varies, so you must check the specific college’s eligibility criteria before applying.

In short, it is possible, but not universally accepted. Always verify the admission rules of the institution you are targeting. All the best.
