Ostomy belts are designed to support your ostomy pouch and secure it in place. If the bag gets too heavy, it can cause the ostomy wafer to pull away from the skin which can lead to leaks. An ostomy belt prevents the wafer from pulling away by keeping the pouch against your body. Another benefit of ostomy belts is that they can make your bag more discreet under clothing. There are different styles of ostomy belts available, such as a narrow elastic style and a wider fabric cover. Both provide the same level of support, so it comes down to personal preference when selecting which style to use.
