According to consulting firm Solidiance, total medical expenditure in six major Southeast Asian countries (Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam) is expected to reach USD 740 billion by 2025, from USD 420 billion in 2017. Most countries have fewer doctors than their population requires. Backed by increasing demand for healthcare in Southeast Asia, app-based consultations are becoming more popular in the region. Though the capacity of telehealth services are limited to basic consultations, they are expected to improve health conditions in underserved areas. One unknown factor for healthcare app operators is future regulation. Since app-based consultation is a new area, there are apparently no clear laws on regulating the business in Southeast Asian markets, which effectively allows new businesses to grow.
