Hello
Shafiya , From some research on internet I found that it is about more than 2.5 lakh for whole course and there are career options also here Experienced dietitians may become assistant, associate, or director of a dietetic department, or become self-employed. Some dietitians specialize in areas such as renal or paediatric dietetics . Besides all these they can also work as private consultant or private practitioner.

Hope it will be helpful for you :)
