An ileostomy bag needs to be emptied multiple times day since the output is loose. A closed ended pouch is not appropriate. Insurance will cover 2 pouches per day. If you choose to go this route, it will be costly as you would need to pay out of pocket. If you have a colostomy and have 1-2 BMs per day, the closed end ostomy pouch is economical and a good choice. Flushable liners are available and can be used for either ileostomies or colostomies but you will need to use a 2-piece system.
