Hello student!
BNYS is also considered as A class Dr of Naturopathy medicine in India and it s recognised by AYUSH ministry. After BNYS you can go for MD in Naturopathy and Yoga. But these both are good when you want to do teaching or job in particular a Naturipathy or AYUSH hospitals. The MSc in medical (non clinical) subjects are too limited for naturopathy we can say after BNYS cant do MSc in subjects like Anatomy, Physiology, Biochemistry, Pharmacology, Community Medicine, etc these courses only avilable for MBBS, BAMS, BDS, BPT.. etc. But BNYS can go for Msc Psycology and Msc in Diet & Nutrition and Msc in Clinical Nutrition courses. After these courses BNYS can become a welness coach or welness Dr.. Nutrition is a good option and very demanding in this era. And after this you can easly get job in Allopathy hospitals along with your AYUSH hospitals. Beside these Accupuncture, Accupressure diploma is best after BNYS.

Hope this helps you!
Regards!
