What should I know before going abroad for treatment?
The CDC says getting medical care in another country can be risky. Infections are the most common problem, including bloodstream infections and diseases like hepatitis B, hepatitis C, and HIV. Quality standards, such as infection control, can differ a lot outside the United States, and accreditation does not guarantee a good result. Flying soon after surgery raises the chance of blood clots, so timing of the flight home matters. If problems come up after you return, follow-up care can cost a lot and your health insurance might not cover it. You might also lack the same legal options if something goes wrong abroad as you would have in the United States.
