The Indian healthcare sector contributes 4% to GDP and is expected to grow at a CAGR of 15% to reach US $160 billion by FY17. It is comprised of hospitals, pharmaceuticals, medical equipment and supplies, medical insurance, and diagnostics. Growth is driven by factors like a fast growing population experiencing more lifestyle diseases, improvements in infrastructure and medical insurance penetration, and increasing medical tourism due to quality care at lower costs than other countries. However, challenges include an inadequate healthcare workforce and the capital intensive nature of the sector.
