This topic is about understanding whether changes in the size and shape of a stoma with different body positions and activities are normal. A person who recently had surgery to create an end ileostomy noticed that their stoma changes in size depending on whether they are lying down, sitting, or standing. They are curious if this is a common experience for others with a stoma.

Here are some helpful insights and advice from others who have shared similar experiences:

1. It is common for a stoma to change in size and protrusion. Many people notice that their stoma retracts when they are lying flat and protrudes more when they are sitting or standing.

2. Some people observe that their stoma enlarges just before passing stool and then shrinks or pulls in during the process, extending again afterward.

3. External factors like cold temperatures or any pressure on the abdomen can cause the stoma to become smaller.

4. Diet can also play a role. Eating high-fiber foods might make the stoma work harder, causing it to temporarily retract or narrow.

5. For those who use irrigation, the stoma may remain extended after the overnight period following an evening irrigation.

Overall, these day-to-day and position-related fluctuations are considered normal and are not typically a sign of any serious issues like pathological retraction.
