There are a number of different types of stoma, but the most common is an ileostomy, which is where the small intestine is diverted through an opening in the stomach. This can be done either permanently or temporarily, depending on the individual's needs.
It is possible to have a natural birth with a stoma, but it will depend on a number of factors such as the type of stoma, the size of the opening and whether or not there are any complications with the pregnancy. If you are considering having a natural birth with a stoma, it is important to speak to your doctor or midwife beforehand to discuss all of the risks and potential complications.
