Technology is advancing at a brisk pace and is carrying along with it its own share of positives and negatives. Where technology has played a very crucial and influencing role is in the field of medicine. The emergence of the Internet of Things (IoT) has taken several industries by storm. However, the healthcare industry has been slower to adopt Internet of Things. The capability of physical devices to capture and transmit data right from environmental conditions to the user behaviours is exactly what IoT does. According to statistics from World Health Organisation, 4.9 million people died from lung cancer, 2.6 million from obesity, 4.4 million from high cholesterol and 7.1 million from high blood pressure. The number is said to increase further. However, IoT comes in as a technological advancement that helps diagnose chronic diseases and help doctors take suitable treatment measures.
The concept of the Internet of Things is a new thing in the field of medicine. The Internet of Things lets integrate devices capable of connecting to the internet and in turn provide real-time information on the state of patients to the doctor who assists. Studies suggest that chronic diseases can be diagnosed and treated with the help of IoT effectively. It transforms the way we keep people safe and healthy especially as the demand for solutions has risen up. The system helps monitor, inform and notify not just the patient but also the healthcare provider with critical information.
According to statistics posted by Marketwatch, the IoT healthcare market is said to reach $136.8 billion worldwide by 2021. At present, there are over 3.7 million medical devices that are connected to and monitor different parts of the body to carry out informed healthcare decisions. The unit refers to the connected system of medical equipment and applications that collect data and is then provided to the healthcare IT systems wirelessly. 
The current day smart devices such as the smartwatches and the smart bands detect your heart rate and your motion. When the wearable is wirelessly connected to a compatible smartphone, the information is transmitted to the mobile device. This is exactly how IoT works. It collects information and provides it to the required systems so that doctors could provide better healthcare outcomes and efficiencies. However, high-speed internet access and favourable government policies are much needed to take these advancements further. 
The Internet of Medical Things (IoMT) provides an effective way to care for our elderly and has a tremendous potential to deal with the rising costs of healthcare. With the ability to track vitals, heart performance, monitor glucose level, sleeping time and other body activities, doctors can monitor their patients on a real-time basis and suggest them suitable medication. IoMT helps remote caregivers ensure the safety of their loved ones and issue a warning if anything goes wrong. With the Internet of Things advancing at an unexpected rate, healthcare solutions are set to become effective and efficient than ever before.
