The human digestive system plays a crucial role in maintaining overall health and well-being. Continuous monitoring of digestive function is essential for early detection and management of gastrointestinal disorders. With the advent of the Internet of Things (IoT), innovative solutions have emerged to enable real-time, remote monitoring of digestive health. This paper explores the applications of IoT technology in human digestive system monitoring, including the use of wearable devices, smart sensors, and ingestible sensors. We discuss the benefits, challenges, and future directions of IoT-based digestive system monitoring, highlighting its potential to revolutionize healthcare delivery in gastroenterology.
