Chronic diseases such as diabetes, heart disease, or asthma are one of the biggest health challenges of the modern world. Their management requires constant care and monitoring, which is a serious burden for healthcare systems. In the digital era, the development of telemedicine, health applications, and telemedicine platforms creates new opportunities in the treatment and monitoring of patients with chronic diseases. Telemedicine, including services such as remote consultations, telemonitoring, and remote rehabilitation, allows patients to access healthcare without having to physically visit the office. Mobile applications allow patients to monitor their health condition, receive medication reminders, or consult with doctors, which increases their involvement in the treatment process. The benefits of telemedicine include improving the availability of health services, especially in rural areas, and saving time and money. Remote monitoring of health parameters allows for a faster response in the event of a deterioration in the patient's condition, and integration with artificial intelligence technology and the Internet of Things (IoT) allows for even more accurate monitoring of health status. Health apps are particularly useful in managing chronic diseases such as diabetes or heart disease, improving control over therapy, and self-management of health. The future of telemedicine, supported by the development of technology, promises further improvements in the care of patients with chronic diseases. The introduction of more individualized medical services based on real-time data can significantly improve the quality of care and reduce the costs of treatment, constituting a key element of the future of healthcare systems.
