Does doctors should mainly focus upon the patients diet rather than focussing upon high expensive medicines prescribing ?

Yes, doctors should prioritize diet and lifestyle guidance, as preventive care often reduces dependency on expensive medications, improves long-term outcomes, and empowers patients to manage chronic conditions more effectively and affordably.

Honestly these days yes, because most of our lifestyle has changed a lot .. so knowing a patients dietary habits will definitely improve the prescription of medications and also improves health if counseled in a correct manner.

balance of both works fast,
only having medicine with poor diet goals nothing.
