I am diabetic and there is a glucose monitoring system, called FreeStyle Libre, that is attached for 2 weeks to the upper arm on my body and it cannot be taken off. In this situation how may I perform Ghusl and Wudhu?
As this matter is a new matter, and the monitor prevents water from reaching to part of your skin, many of our Maraaji' of Taqleed say that you need to perform both Ghusl and Tayammum. During the Ghusl, you need to wipe over the monitor on your body.
Wassalam.
