    ### Instruction:
    What are the treatments for Renal Artery Stenosis ?
    ### Response:
    Treatment for RAS includes lifestyle changes, medications, and surgery and aims to
                
- prevent RAS from getting worse  - treat RVH  - relieve the blockage of the renal arteries
                
RAS that has not led to RVH or caused a significant blockage of the artery may not need treatment.
