An ostomy bag, also known as a stoma bag or pouch, is a prosthetic medical device that collects waste from a surgically created opening (stoma) from the digestive or urinary system. The bag adheres to the skin around the stoma and is typically disposable.
An ostomy is a surgical opening to allow stool or urine to leave the body. A stoma is an opening in the abdomen. Ostomy and stoma are interchangeable words. Ostomies can be temporary or permanent.
An ostomy bag should be emptied when it is about one-third to one-half full. This is typically several times a day, but the frequency can vary based on individual factors like diet and the type of ostomy.
The frequency of changing an ostomy bag varies based on the type of ostomy and individual needs, but generally, a drainable ostomy pouch is changed every 2–4 days. Pre-cut, closed ostomy bags are usually changed daily.
To prevent leakage, ensure a good fit of the skin barrier (the part that sticks to the skin and protects it). This often involves correctly cutting the hole to match the size and shape of the stoma. Use accessory products such as paste or rings for a better seal, and change the bag before it's too full to prevent undue pressure on the seal.
Always change the bag immediately if there's any sign of irritation or leakage.
