The company introduced AI-based symptom analysis tools, improving diagnostic accuracy by 15% and reducing average consultation wait times to under 3 minutes.
The Rise of Continuous Glucose Monitoring and Personalized Healthcare
In the field of diabetes management technology, continuous glucose monitoring (CGM) technology is leading the innovation. Dexcom, based in San Diego, California, holds a dominant market share in the CGM market, with its latest product, the G7, measuring blood glucose every 10 minutes and transmitting data to smartphones within a minute. Dexcom’s revenue in the third quarter of 2025 increased by 26% year-over-year to $980 million, with the number of users worldwide exceeding 2 million. The market expansion is accelerating, particularly with the increasing use of CGM for health management purposes by non-diabetic individuals.
In the personalized medical services market, integrated solutions combining genomic analysis and wearable data are gaining attention. 10x Genomics, based in Pleasanton, California, supports the prediction of individual disease risks and the development of personalized treatments through single-cell analysis technology. The company’s Chromium platform can simultaneously analyze millions of cells in a single experiment and is widely used in cancer research, immunology, and neuroscience. 10x Genomics recorded $140 million in revenue in the third quarter of 2025, an 8% growth year-over-year.
With the growth of the digital healthcare market, concerns about data security and privacy are also increasing. The U.S. Department of Health and Human Services has strengthened HIPAA regulations in 2025, significantly enhancing security standards for wearable devices and mobile health apps. The European Union is also enforcing stricter GDPR applications on medical data, leading to increased compliance costs for global digital healthcare companies. The Korean government is also making efforts to find a balance between innovation and security by preparing guidelines for the use of medical data through amendments to the Personal Information Protection Act.
Market experts predict 2026 as a turning point for the digital healthcare market. According to Goldman Sachs analysis, as the diagnostic accuracy of wearable medical devices reaches the level of traditional medical devices, the remote diagnostic market is expected to expand in earnest. Particularly, the adoption of digital healthcare is accelerating in the Asia-Pacific region, with China and India showing an annual growth rate of over 35%. Korea aims to achieve a 5% market share in the global digital healthcare market by 2030 through the K-Digital Healthcare policy.
From an investment perspective, global venture capital investment in the digital healthcare sector is expected to reach $28 billion in 2025, a 15% increase from the previous year.
