In my opinion u should get the health insurance by pvt insurance provider, that would be safe, otherwise also public health system is okay as long as things goes well, but if u have to approach any doctor in hamad hospital then u need to wait for appointment which u may get after 20-25days and so on,

So to avoid that if u prefer to go for pvt clinis or hospitals, the cost will be very high, so better to opt for insurance.
