What are the symptoms of a failing or blocked intestinal stent?

A failing or blocked intestinal stent can lead to various symptoms, depending on the location and severity of the blockage. Some common symptoms include:

1. **Abdominal pain or cramping** – Persistent or worsening pain, particularly after eating, is a common sign of a blocked or malfunctioning stent.

2. **Nausea and vomiting** – These may occur due to a buildup of food or fluids above the blockage.

3. **Bloating and abdominal distension** – Swelling of the abdomen can result from the inability to pass gas or stool.

4. **Constipation or inability to pass stool** – This may indicate a partial or complete blockage of the intestine.

5. **Diarrhea** – In some cases, liquid stool may pass around the blockage, giving the appearance of diarrhea.

6. **Loss of appetite** – A blocked stent may lead to a decreased desire to eat, as eating can worsen symptoms.

7. **Unexplained weight loss** – This can result from prolonged difficulty eating and digesting food.

If any of these symptoms appear, immediate medical evaluation is necessary, as a blocked or failing stent can lead to complications such as infection or bowel perforation.
