==Overview== | |||
[[Irritable bowel syndrome]] is a disorder characterized most commonly by cramping, [[abdominal pain]], [[bloating]], [[constipation]], and [[diarrhea]]. [[Irritable bowel syndrome|IBS]] causes a great deal of discomfort and distress, but it does not permanently harm the [[Intestine|intestines]] and does not lead to a serious disease, such as [[cancer]]. Most people can control their symptoms with [[Diet (nutrition)|diet]], [[Stress (medicine)|stress]] management, and prescribed medications. For some people, however, [[Irritable bowel syndrome|IBS]] can be disabling. They may be unable to work, attend social events, or even travel short distances. | |||
As many as 20 percent of the adult population, or one in five Americans, have symptoms of [[Irritable bowel syndrome|IBS]], making it one of the most common disorders diagnosed by doctors. It occurs more often in women than in men, and it begins before the age of 35 in about 50 percent of people. | |||
==What are the symptoms?== | |||
Symptoms range from mild to severe, however most people have mild symptoms. [[Irritable bowel syndrome|IBS]] symptoms may be worse in patients with underlying stress or mood disorders such as [[anxiety]] and [[depression]], but it is important to understand that these conditions do not cause [[Irritable bowel syndrome|IBS]]. Symptoms may include: | |||

Researchers have yet to discover any specific cause for IBS.

*Recent research has reported that serotonin is linked with normal gastrointestinal (GI) functioning. Serotonin is a neurotransmitter, or chemical, that delivers messages from one part of your body to another. Ninety-five percent of the serotonin in your body is located in the GI tract, and the other 5 percent is found in the brain. Cells that line the inside of the bowel work as transporters and carry the serotonin out of the GI tract. People with IBS, however, have diminished receptor activity, causing abnormal levels of serotonin to exist in the GI tract. As a result, they experience problems with bowel movement, motility, and sensation—having more sensitive pain receptors in their GI tract. | *Recent research has reported that serotonin is linked with normal gastrointestinal ([[Gastrointestinal tract|GI]]) functioning.

Overview
Irritable bowel syndrome is a disorder characterized most commonly by cramping, abdominal pain, bloating, constipation, and diarrhea. IBS causes a great deal of discomfort and distress, but it does not permanently harm the intestines and does not lead to a serious disease, such as cancer. Most people can control their symptoms with diet, stress management, and prescribed medications. For some people, however, IBS can be disabling. They may be unable to work, attend social events, or even travel short distances.
As many as 20 percent of the adult population, or one in five Americans, have symptoms of IBS, making it one of the most common disorders diagnosed by doctors. It occurs more often in women than in men, and it begins before the age of 35 in about 50 percent of people.
What are the symptoms?
Symptoms range from mild to severe, however most people have mild symptoms. IBS symptoms may be worse in patients with underlying stress or mood disorders such as anxiety and depression, but it is important to understand that these conditions do not cause IBS. Symptoms may include:
- Abdominal distention
- Abdominal fullness, gas, bloating
- Abdominal pain or tenderness that:
- Comes and goes
- Goes away after a bowel movement
- Occurs after meals
- Chronic and frequent constipation, usually accompanied by pain
- Chronic and frequent diarrhea, usually accompanied by pain
- Emotional distress
- Depression
- Loss of appetite
- Nausea and vomiting
What are the causes?
Researchers have yet to discover any specific cause for IBS. One theory is that people who suffer from IBS have a colon, or large intestine, that is particularly sensitive and reactive to certain foods and stress. The immune system, which fights infection, may also be involved.

Who is at highest risk?
Risk factors for IBS:
- Gender: females are at higher risk than males
- Age: people younger than 35 are at greater risk
Diagnosis
Most of the time, your doctor can diagnose IBS without ordering many tests. Tests usually reveal no problems.
Some patient may need an endoscopy, especially if symptoms begin later in life. Younger patients with persistent diarrhea may need this test to look for inflammatory diseases that can cause similiar symptoms such as Crohn's disease or ulcerative colitis. You may need additional tests if you have blood in your stool, weight loss, or signs of anemia.
Patients over age 50 should be screened for colon cancer.
When to seek urgent medical care?
Call your health care provider if you have symptoms of irritable bowel syndrome or if you notice a persistent change in your bowel habits.
Treatment options
The goal of treatment is to relieve symptoms.
Lifestyle changes can be helpful in some cases of IBS. For example, regular exercise and improved sleep habits may reduce anxiety and help relieve bowel symptoms.
Dietary changes can be helpful, but no specific diet can be recommended for IBS in general because the condition differs from one person to another. Increasing dietary fiber and avoiding items that stimulate the intestines such as caffeine may help.
Foods and drinks that may cause or worsen symptoms include:
- Fatty foods, like french fries
- Milk products, like cheese or ice cream
- Beans, onions, celery (gas producing foods)
- Alcohol
- Caffeinated drinks, like coffee and some sodas
- Carbonated drinks, like soda
Other possible treatments may include:
- Counseling in cases of severe anxiety or depression
- Antidiarrheal medications for those whose main symptom is diarrhea
- Low-dose antidepressants to help relieve intestinal pain
- Medications to stimulate bowel movements for those with constipation
Medications
Medications used to help with symptoms of IBS include:
- Laxatives treat constipation. Many kinds of laxatives are available. Your doctor can help you find the laxative that is right for you.
- Antispasmodics control spasms in the colon and help ease abdominal pain.
- Antidepressants, even in lower doses than are used for treating depression, can help people with IBS. They can help reduce the abdominal discomfort or pain associated with IBS and, depending on the type chosen, may help the diarrhea or constipation.
Another drug is sometimes prescribed for the treatment of IBS. Alosetron hydrochloride (Lotronex) is for women with severe IBS whose main symptom is diarrhea. Because it can cause serious side effects, Lotronex is only used if other medicines do not work.
You need to follow your doctor’s instructions when you use the medicine. Otherwise, you may need to keep taking it in order to have a bowel movement. Talk with your doctor about potential side effects and what to do if you experience them.
