Ileus is a serious concern. Nevertheless, people with an ileus frequently don't know that food is building up in their intestines, so they proceed to eat.
Fremont, CA: The human body's intestines are about 28 feet long. This means the foods eaten have a long way to travel before fully digested and excreted.

The human body's intestines complete this task through muscle contractions that move in a wave-like motion. Named peristalsis, these muscle contractions move your digested food ahead.
Still, if something like muscle or nerve problems slows down or blocks this motion, the outcome can be a serious traffic jam in your intestines.
Ileus is the scientific term for this lack of movement somewhere in the intestines, leading to a buildup and potential blockage of food material.
An ileus can lead to intestinal obstruction. This conveys no food material, gas, or liquids can get through.
It can happen as a side effect after surgery. Yet, there are other causes of this condition.
Ileus is a serious concern. Nevertheless, people with an ileus frequently don't know that food is building up in their intestines, so they proceed to eat. This drives more and more material toward growth.
Without care, the ileus can pierce or tear the intestine. This generates bowel contents — which have high levels of bacteria — to leak into areas of your body cavity. This can be deadly.
What are the reasons for an ileus?
An ileus is usual after surgery since people are often prescribed medication that can delay intestinal movement. This is a kind of paralytic ileus.
In this case, the intestine is not blocked. Rather, it isn't stirring properly. So the effect is little to no movement of digested food through your intestines.
Instances of medications that can cause a paralytic ileus to include:
• hydromorphone (Dilaudid)
• morphine
• oxycodone
• tricyclic antidepressants, for example, amitriptyline and imipramine (Tofranil)
But, there are several other possible causes of ileus. These include:
• intestinal cancer
• diverticulitis
• Parkinson's disease, which impacts muscles and nerves in the intestines
• Crohn's disease hardly causes a blockage but may reason the intestinal walls to thicken due to autoimmune inflammation
How is an ileus treated?
The treatment for an ileus relies on its severity. The severity can count on whether it's causing a partial or total intestinal obstruction or if it's a paralytic ileus.
Partial obstruction
At times a condition like Crohn's disease or diverticulitis will mean that part of the intestine is not moving. Nevertheless, some bowel material can get through.
In this case, if you are otherwise stable, your doctor may suggest a low-fiber diet. This can support reducing the bulky stool, making it easier to pass.
Nevertheless, if that doesn't work, surgery may be needed to repair or move the affected portion of the bowel.
Complete obstruction
A total obstruction is a medical emergency.
Treatment will depend on your overall health. For instance, extensive abdominal surgery is not appropriate for some people. This involves older adults and those with colon cancer.
A doctor may apply a metal stent to open the intestine in this case. Preferably, food will start to pass with the stent.
Nevertheless, abdominal surgery may still be required to remove the blockage or the damaged intestine.
What are the symptoms of an ileus?
An ileus can reason extreme abdominal discomfort.
Symptoms connected with an ileus include:
• abdominal cramping
• appetite loss
• sensation of fullness
• constipation
• impotence to pass gas
• abdominal swelling
• nausea
• vomiting, particularly with stool-like contents
How is an ileus diagnosed?
Your doctor will generally first listen to a description of your symptoms. Then, you'll possibly be asked about any history of medical conditions, prescribed medications, and surgeries, mainly recent procedures.
Your doctor may then execute a physical exam, looking at your abdomen for signs of swelling or tightness. Your doctor will also hear with a stethoscope to your abdomen for regular bowel sounds.
If your bowels aren't moving due to ileus, your doctor may not hear anything or may hear excessive bowel sounds.
Imaging studies are generally ordered after a total physical exam. These can suggest where an ileus is located by showing a buildup of gas, an enlarged intestine, or even an obstruction. In addition, your doctor may employ these to identify areas where your bowel content seems consolidated.
Examples of imaging studies incorporate:
• Plain film X-ray. This may show signs of captured gas and possibly the obstruction, but plain film X-rays aren't generally the most conclusive way to diagnose an ileus.
• CT scan. This scan gives more detailed X-ray images to aid your doctor in identifying the potential area where the ileus is situated. A CT scan generally uses contrast agents injected intravenously or taken orally.
• Ultrasound. An ultrasound is usually used to recognize an ileus in children.
Sometimes, your doctor may use a diagnostic procedure familiar as an air or barium enema.
The doctor enters air or barium sulfate, a radiopaque substance, over your rectum into your colon. While the doctor does this, a technician carries X-rays of your abdomen.
The air or barium appears on the X-ray to help the technician view any potential obstruction.
In some children, this procedure can treat an ileus caused by intussusception.
What complications can an ileus cause?
An ileus can develop into a grave and potentially life-threatening situation.
Two of the harshest complications are necrosis and peritonitis.
Necrosis
Necrosis is the premature death of cells or tissue. It can happen when an obstruction cuts the blood supply to the intestine.
Peritonitis
A bowel perforation because of necrosis can cause peritonitis. This is severe inflammation in the abdominal cavity due to bacteria or fungus.
Can an ileus be prevented?
Most risk factors associated with an ileus, such as injury or chronic illness, are not preventable.
If you're going to have surgery, the chances of getting an ileus should be considered. Still, it should not keep you from having needed surgery.
Awareness of the symptoms of ileus is important in seeking prompt treatment to keep it from worsening.
