WHAT YOU NEED TO KNOW:
What is a bowel obstruction?
A bowel obstruction occurs when your large or small intestine is completely or partly blocked. The blockage prevents food and waste from passing through normally.
What causes a bowel obstruction?
- Adhesions are bands of scar tissue that may form after a surgery. An adhesion attaches your intestine to a nearby organ or to the wall of your abdomen. This may pull your intestine out of place and cause an obstruction.
- A hernia occurs when part of the intestine bulges through the muscle wall of the abdomen. The hernia may cause an obstruction if the intestine becomes trapped.
- A tumor may cause a blockage of the intestine.
- A foreign body can block the intestine. A foreign body is something other than food that is swallowed.
- A sliding or folding of part of the intestine into another portion of the intestine may cause a bowel obstruction.
- Medical conditions such as Crohn disease and diverticulitis cause changes to the intestine that may cause a bowel obstruction.
- A twisting of the intestine may cause a bowel obstruction.
What are the signs and symptoms of a bowel obstruction?
- Nausea and vomiting
- Abdominal pain
- Enlarged abdomen
- Decreased or no bowel movements or gas
How is a bowel obstruction diagnosed?
- Blood tests may show if you have an infection, or if you are dehydrated. Dehydration can develop when your intestines cannot absorb liquid properly.
- An x-ray takes pictures of the organs inside your abdomen. The pictures are used to look for an obstruction.
- A CT or MRI scan may be used to take pictures of your intestines. The pictures may show the location and cause of your blockage. You may be given a dye before the pictures are taken to help healthcare providers see the blockage better. Tell the healthcare provider if you have ever had an allergic reaction to contrast dye. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.
- An ultrasound uses sound waves to show pictures of your intestines on a monitor. An ultrasound may be done to find the location of your obstruction.
How is a bowel obstruction treated?
- An IV may be used to give you liquids and nutrition. You may not be able to eat or drink anything until your healthcare provider says it is okay.
- A nasogastric tube may be put into your nose. The tube passes through your throat and is guided into your stomach. The tube will be attached to a suction device that removes air and fluid from your stomach.
- Antibiotics may be given to help treat or prevent an infection caused by bacteria.
- Surgery may be done to treat the cause of the blockage.
