Impacted Bowel

What is fecal impaction of the colon?

When you eat food, it breaks down in your stomach and passes through your intestines. This process is known as digestion. Then, the walls of your intestines absorb nutrients from the food. What remains as waste passes along to your colon and rectum.

At times, things may go wrong in this process and the waste becomes stuck in the colon. This is known as fecal impaction of the colon.

When you have an impacted colon, your feces become dry and won’t budge, making it impossible to excrete them from your body. Impacted feces block the way for new waste to leave the body, causing it to back up.

Symptoms

All symptoms of fecal impaction are serious and warrant prompt medical attention. They include:

Severe symptoms include:

Causes of constipation and impaction

The primary cause of fecal impaction of the colon is constipation. Constipation is difficulty passing stool or the infrequent passing of stool. It’s often the result of:

Constipation is painful, and people who have it often feel bloated and uncomfortably full. You may also feel the need to go to the bathroom without being able to. When a stool doesn’t pass through the intestinal system, it can become dry and hard and lodge in the colon. This is called fecal impaction of the colon.

Once fecal impaction occurs, your colon won’t be able to remove the feces from the body using its normal contraction process.

How it’s diagnosed

If you think you have fecal impaction or if you have persistent symptoms of constipation that aren’t getting better, see your doctor immediately. They will perform a physical exam, which includes an examination of your abdomen to confirm the diagnosis. They’ll press down on your abdomen to feel for any masses or hardened areas, which can help them locate the affected parts of your digestive system.

After this, your doctor will administer a digital rectal exam to check for fecal impaction. In this test, your doctor puts on a glove, lubricates one of their fingers, and inserts it into your rectum. This procedure doesn’t usually cause pain, but you may feel some discomfort.

If your doctor suspects impaction after performing the exams, they may order an X-ray of the abdomen. Other possible procedures are an abdominal ultrasound or a viewing of the colon using a tiny microscope called a sigmoidoscope. A barium enema can also highlight the problem areas. A barium enema involves inserting a dye into your rectum and then taking an X-ray of the colon and rectum.

Treatment options

Laxatives

The first method of treatment for fecal impaction is usually an oral laxative. There are many over-the-counter laxatives that can help stimulate clearing of the colon. Sometimes, a medicated suppository, which is medication that’s placed into the rectum, may help.

Manual removal

If a laxative or a suppository doesn’t unblock the feces from your colon, your doctor will remove the feces manually. To do this, they’ll insert their gloved finger into your rectum and remove the blockage.

Enema

If your doctor can’t remove the entire blockage, they’ll use an enema to remove it. An enema is a small, fluid-filled bottle with a nozzle attached. The nozzle inserts into the rectum. Your doctor squeezes the bottle, releasing the liquid into the rectum and colon. This lubricates the colon and moistens the feces, making it easier to dislodge.

Water irrigation

Water irrigation involves pushing a small hose up through the rectum and into the colon. The hose connects to a machine that emits water through the tube. After the irrigation, your doctor will massage your abdomen, moving the waste out your rectum through another tube.

Associated complications

Complications of fecal impaction of the colon include:

It’s important to pay attention to your bowel and visit a doctor if you suspect any problems.

Prevention and tips for healthy bowel movements

One way to prevent fecal impaction of the colon is to avoid becoming constipated. Some diseases and certain medications make it impossible to avoid constipation, but making small lifestyle changes can help. Try these tips:

  • Drink plenty of water every day to prevent dehydration.
  • Drink other fluids, such as prune juice, coffee, and tea, that act as natural laxatives.
  • Eat foods that are high in fiber, such as whole wheat, pears, oats, and vegetables.
  • Reduce your intake of foods that are high in sugar, which can cause constipation.
  • Exercise daily to help keep your digestive system running well.
