A South Korean telehealth company, DoctorNow, is utilizing artificial intelligence to provide medical information to users, but cautions that the AI’s responses should not be considered definitive medical advice. The AI, which has been trained on a dataset of one million consultations, offers guidance on a range of health concerns, including dermatological issues.

Recently, a user consulted DoctorNow’s AI regarding a rash of red spots appearing on their arm, and concerns about a possible connection to herpes simplex virus type 1 (HSV-1). The AI responded that the spots could be caused by a variety of factors, including skin irritation, allergic reactions, capillary bleeding, mild dermatitis, or vascular tumors. Even as HSV-1 typically manifests as blisters around the mouth, the AI noted a direct link to red spots on the arm is uncommon.

The AI advised that if the spots are fading, it suggests natural healing. Still, it recommended a consultation with a dermatologist or infectious disease specialist for further investigation and potential testing, rather than a visit to a general practitioner or urologist. The AI emphasized the importance of informing the medical professional of any accompanying symptoms, such as itching, pain, or warmth.

DoctorNow explicitly states that its AI-powered responses are for reference only and may contain inaccuracies. The company disclaims any responsibility for decisions made based on the AI’s advice, clarifying that it should not be interpreted as a substitute for professional medical judgment or treatment. The AI’s responses are developed in collaboration with medical professionals and are optimized for health information, according to the company.

The company’s disclaimer, prominently displayed with the AI’s responses, underscores the limitations of AI in healthcare and the continued need for qualified medical professionals to provide accurate diagnoses and treatment plans.

South Korean doctors are increasingly utilizing artificial intelligence to improve the early detection of digestive diseases, according to reports from earlier this year. The technology is being applied to areas ranging from analyzing medical imaging to assisting in personalized treatment plans.

The integration of AI in healthcare is expanding rapidly, with applications in radiology, drug discovery, and patient care. According to a report from May 2025, physicians are leveraging AI to enhance the accuracy and efficiency of diagnoses. “AI provides consistent analytical capabilities, reducing diagnostic variations based on a doctor’s condition,” stated Jeong Jae-won, president of the Speedyeon Internal Medicine clinic, in a report by the Busan Ilbo. “It can contribute to maintaining and standardizing the overall quality of endoscopic examinations.”

Specifically, AI is proving valuable in identifying subtle anomalies during endoscopic procedures, which can be easily overlooked by the human eye. A joint study conducted by Seoul National University Hospital’s pathology professor Lee Seong-hak and the gastroenterology department of the University Hospital Augsburg in Germany, focused on early detection of cancers in the esophagus and stomach. Their research, published earlier this year, demonstrated AI’s ability to improve diagnostic accuracy and reliability in detecting Barrett’s esophagus, esophageal squamous cell carcinoma, and early gastric cancer.

The importance of early diagnosis in gastrointestinal cancers is underscored by survival rates. Although the five-year survival rate for advanced gastric cancer is less than 30%, it rises to over 90% for early-stage diagnoses. AI algorithms are being trained on vast datasets of endoscopic images to identify minute lesions that might otherwise be missed. Some studies have shown AI achieving over 98% sensitivity and specificity in predicting the depth of early cancer invasion and identifying ambiguous lesion boundaries, as reported by Medical Observer.

The use of AI-assisted endoscopy is not without its challenges. The technology requires substantial investment and ongoing refinement. However, the potential benefits in terms of improved patient outcomes and reduced healthcare costs are driving its adoption. The Doctor Now AI platform, utilizing data from over one million consultations, is providing preliminary guidance to patients experiencing digestive issues, though it explicitly states its responses are for reference only and should not be considered medical advice.

As of February 17, 2026, the full clinical implications and long-term impact of AI in gastroenterology remain under investigation, with ongoing research focused on refining algorithms and expanding their application to a wider range of digestive diseases.

A South Korean artificial intelligence chatbot, Doctor Now, has analyzed over one million counseling sessions to provide personalized advice, including guidance on weight fluctuations following overeating. The AI’s responses, developed in collaboration with medical professionals, suggest that a temporary weight gain of 0.8kg following a large meal is likely attributable to food volume, fluid retention, and the digestive process, and can often be reversed within a day through dietary adjustments and hydration.

Doctor Now’s assessment centers on the understanding that short-term weight changes are frequently influenced by factors such as food intake, hydration levels, and the body’s digestive functions. Overconsumption leads to a temporary increase due to the weight of the food itself and undigested material within the system. High sodium or carbohydrate intake can contribute to water retention, exacerbating the weight gain. The AI advises that restoring normal eating patterns and maintaining adequate hydration can facilitate the natural elimination of excess fluids and return weight to its previous level.

The AI’s response emphasizes that a fluctuation of 0.8kg falls within the range of typical daily weight variation and should not be a cause for significant concern. However, it underscores the importance of consistent dietary habits and regular exercise for long-term weight management. According to career resources, senior editors, like those overseeing the development of such AI tools, are responsible for maintaining editorial integrity and upholding standards of accuracy and consistency.

South Korean telehealth provider Doctor Now has undergone a significant strategic shift, rebranding itself as an “AI medical portal” as it navigates a changing regulatory landscape for non-face-to-face medical consultations. The company, once a leader in remote healthcare services, is now emphasizing artificial intelligence-driven diagnostic support and real-time medical advice, following a curtailment of the scope of its original business model.

The move comes as South Korea’s pilot program for non-face-to-face medical consultations nears its end in September 2024, leading to a reduction in the availability of such services. Doctor Now is responding by expanding its “real-time free consultation” service, previously offered on a limited basis, and introducing a new “AI doctor diagnosis” feature, according to a statement released by the company and reported by The Electronic Times.

Doctor Now’s CEO, Jang Ji-ho, stated that the company aims to turn into a leading “medical portal” offering 24-hour real-time medical consultations and facilitating connections between patients and appropriate healthcare providers. He described the ambition as building a “real-time, trust-based ‘J.A.R.V.I.S.’ for the medical field,” referencing the AI assistant from the Iron Man franchise.

The AI-powered diagnostic service is built upon a dataset of one million consultation cases, allowing it to provide responses to patient inquiries. An example provided by Doctor Now involved a female patient expressing concerns about irregular menstruation and weight gain. The AI’s response highlighted potential links to environmental changes, stress, lifestyle shifts, and hormonal imbalances, specifically mentioning the possibility of Polycystic Ovary Syndrome (PCOS). The AI advised the patient to seek a consultation with a gynecologist for hormone testing and an ultrasound.

Doctor Now, which currently holds the title of the number one non-face-to-face medical consultation app in South Korea according to both the 2025 Han Kyung Business Korea Consumer Satisfaction Index and the 2024 Weekly Dong-A Korea Customer Satisfaction Index, is also continuing to offer its core services, including remote consultations for conditions like colds, skin issues, and pediatric care, alongside prescription and delivery services. The app allows users to select doctors based on consultation fees, and reviews.

The company’s shift reflects a broader adaptation within the telehealth industry in South Korea, as providers seek new avenues for growth in the face of evolving regulations. Doctor Now’s future trajectory will likely depend on its ability to establish itself as a trusted and reliable AI-driven medical information resource.

A South Korean woman traveling in Japan experienced an allergic reaction on her face, prompting questions about access to telemedicine services for citizens abroad. The incident highlights the limitations of remote healthcare options, even with pre-registration and payment information established.

According to a response from the South Korean telehealth provider Dr. Now, utilizing their app while overseas is possible if a user has completed both identity verification and credit card registration. However, access to care is contingent upon the individual’s national health insurance status. Individuals covered under standard health insurance provisions may be eligible for a consultation, but the final decision rests with the physician.

Dr. Now’s AI-powered response emphasizes that a physician may deem a virtual consultation unsuitable, potentially denying care. Even if a prescription is issued, obtaining medication in Japan using a South Korean prescription is unlikely. The company advises that severe symptoms warrant a visit to a local medical facility.

The situation underscores the challenges of providing consistent healthcare access to citizens traveling internationally. While telemedicine offers a potential solution, logistical hurdles related to prescription fulfillment and varying medical regulations complicate its implementation. A 2021 report by the Al Jazeera Media Institute notes the critical role of senior editors in establishing newsroom processes for utilizing user-generated content and eyewitness media, highlighting the need for clear protocols in rapidly evolving situations like this one.

Level 7 apprenticeships in journalism, as outlined by Skills England, emphasize the importance of sound editorial judgment and understanding of relevant legal codes. This context is relevant as news of this incident spreads, requiring careful reporting and verification of information.

As of February 12, 2026, Dr. Now has not issued a further statement regarding policy adjustments for international travelers.
