What is Chronic Idiopathic Constipation?

Chronic idiopathic constipation (CIC) is an ongoing condition without any known cause or identified underlying illness. Constipation is a condition that can be defined as a state of unsatisfactory defecation, with characteristic features of infrequent stools and difficulty in passing stools, or both.[1] Eight million people in the US seek medical care for constipation every year, and one million are hospitalized.[2] It is likely that many people who have CIC do not report the condition to their doctors because they are embarrassed or do not see it as a major problem requiring medical care.

CIC and Irritable Bowel Syndrome both present as chronic constipation,[2] and are distinct from acute constipation. Acute constipation usually has an organic cause, such as medication or a medical condition, while chronic constipation usually does not, although medication can sometimes play a role.[3] The term idiopathic means that the disorder arises spontaneously, without any known cause. Chronic idiopathic constipation, therefore, is a type of chronic constipation that has no obvious cause. It is a form of functional constipation.

CIC is characterized by infrequent stools which are often difficult to pass. It typically affects women and older adults. The typical symptom of this condition is passing fewer than 3 bowel movements per week for more than 6 months.

To diagnose CIC, a physician usually excludes all other causes of constipation. The treatment options are limited but include dietary changes and physical exercise.


Infrequent bowel movements and difficulty passing stool, are the most common symptoms. If you experience any of the symptoms listed below more than 25% of the time for six months or more, you may need to be assessed for CIC:[1][2][4]

  • Straining
  • Hard stools
  • A feeling of incomplete evacuation, i.e. a sensation of stool remaining in the bowel after defecating
  • A feeling of blockage in the anus or rectum
  • Use of manual maneuvers, such as using the hands, to facilitate defecation

In addition, a major symptom is having fewer than three bowel movements a week.

Good to know: Irritable Bowel Syndrome shares some symptoms with chronic idiopathic constipation, but people with IBS report pain and bloating more often than people with CIC, and report that their symptoms improve after defecation. This is not the case with CIC. People with CIC almost never experience diarrhea without using laxatives.[1] They also experience normal loose stools only rarely. For more information, see this resource on Irritable Bowel Syndrome. If you are experiencing uncomfortable symptoms, You can search for the nearest doctor Find my doctor.

There are several gastroenterological symptoms that indicate that chronic constipation may have a serious medical condition as its underlying cause, rather than being idiopathic. These include:[2][3][4]

  • Distended abdomen/severe bloating
  • Vomiting
  • Blood in the stool
  • Hematochezia[5]
  • Unintended weight loss
  • Anemia
  • Severe constipation of recent onset
  • Rapid worsening of constipation
  • Family history of colon or rectal cancer

These symptoms are more likely to indicate a serious underlying condition in people who are over 50 years of age at the time of symptoms first appearing.

Good to know: Constipation is a possible symptom of colorectal cancer, a common gastroenterological cancer that usually affects people who are older than 60 years of age. It is associated with Crohn’s disease and ulcerative colitis. For more information, see this resource on colorectal cancer. If you or someone you care for are experiencing symptoms that are worrying you, Reaching out to your doctor is your best option Doctor near me.

Causes of chronic idiopathic constipation

CIC is most commonly seen in women and older adults. The causes of chronic idiopathic constipation are largely unknown. However, possible causes include a reduction in fluid and fiber intake in the diet, changes in water balance, and changes in contractility of the colon.

There are several different forms of CIC:[4]

  • Normal transit constipation, where the stool may be harder than normal and therefore more difficult to pass, but moves through the colon at a normal speed
  • Slow transit constipation, where stools move through the colon more slowly than usual
  • Disorders of defecation or evacuation

Disorders of defecation or evacuation include:[1][4]

  • Rectocele, a condition where the wall of the rectum bulges into the wall of the vagina inside the body and forms a pouch
  • Rectal prolapse, a condition where the rectum protrudes through the anus and becomes visible outside the body
  • Dyssynergic dysfunction

Dyssynergic dysfunction arises from problematic coordination of the various muscles and sphincters that control defecation. Defecation requires the muscles involved to coordinate the creation of increased pressure inside the rectum, followed by relaxation of the internal and external anal sphincters and relaxation of the perineal muscles.[1] This requires the coordination of the pelvic floor muscles, abdominal muscles, and the muscles in the rectum.[4]

If these structures do not work together, defecation becomes difficult. People experiencing dyssynergic dysfunction often report a feeling of obstruction and incomplete evacuation. Complications of dyssynergic dysfunction include rectocele, anal fissure and rectal prolapse.

In some cases, chronic constipation may be caused by certain medications, such as:[3]

  • Antihistamines
  • Antipsychotic medications
  • Antispasmodic medications
  • Opioids
  • General anesthetics
  • Antiparkinsonian drugs

Good to know: Medication-related constipation may be chronic (long-lasting) or acute (short-term), and may improve if use of the medication that is causing it is stopped.


The diagnosis is usually based on the symptoms that a person is experiencing and on conducting a physical examination. To confirm the diagnosis, all other causes of constipation – for example, a medical condition, or medication – should be excluded.

Doctors who treat constipation are often specialists in gastroenterology. There are various international gastroenterological criteria that help doctors to determine whether CIC, rather than IBS, is present.

Some tests that may be done to aid diagnosis include:[2][4]

  • Colonoscopy, in which an endoscopic camera is inserted into the colon, used to identify structural problems. See this resource for more information on preparing for a colonoscopy.
  • Blood tests to check for infection and other disorders. See this resource for more information on blood test results.

Colonoscopy is used conservatively. MRI scans are also used sometimes.

Good to know: If the person with CIC does not meet the criteria for being at high risk of colorectal cancer, doctors will usually be conservative about ordering diagnostic tests and instead rely on taking a history from the affected person and evaluating their symptoms. Tests such as manometry, motility capsules, Sitz markers, and scintigraphy are generally rarely used.


As it is not possible to determine the cause of CIC, the treatment options tend to be limited. Dietary changes, like increasing dietary fiber and water intake, are usually helpful, as is doing regular physical exercise. However, diet, fluid intake, and exercise are not uniformly effective, and some people with CIC may be recommended to use:[1][2]

  • Fibre supplements such as psyllium, calcium polycarbophil, inulin and maltodextrin
  • Osmotic laxatives such as polyethylene glycol or lactulose
  • Stimulant laxatives such as bisacodyl, glycerol or sodium picosulfate

Laxatives can help with softening stool and improving the regularity of bowel movements. Fiber supplements have a similar effect.

People who do not find that laxatives provide enough relief from the symptoms of CIC, or for whom laxatives are not recommended, may find serotonin agonists, such as prucalopride or velusetrag, useful.

However, the main medications that are recommended when laxatives do not work or cannot be used are lubiprostone (a fatty acid) and linaclotide (an oligo-peptide agonist).[1] These medications work by increasing the amount of chloride that is secreted into the gut, which increases the amount of fluid in the gut, which in turn stimulates bowel movements.[2] One side effect of linaclotide is diarrhea. Otherwise, both drugs are very effective for CIC.

People with CIC resulting from dyssynergic dysfunction may find biofeedback useful. (see FAQs). If done by a trained therapist, biofeedback can be used to correct incorrect defecatory techniques and in that way “retrain” the pelvic floor.[1]

Probiotics, which replenish or balance the growth of healthy intestinal bacteria, may be helpful for some people.

u003cstrongu003eHow should CIC be treated in children?u003c/strongu003e

Young children may not be able to describe the symptoms of chronic idiopathic constipation to their caregivers, so it is important to be vigilant for signs of abdominal distress or discomfort in children, especially surrounding bowel movements. Treating constipation in children promptly can prevent it from becoming chronic. u003cstrongu003eFrequent soiling is a symptom of CIC which is specific to children.u003c/strongu003eu003csupu003eu003ca href=u0022#fn6u0022u003e[6]u003c/au003eu003c/supu003e Children may experience feelings of shame and therefore not report discomfort to their caregivers. In addition, the feelings of discomfort and difficulty during bowel movements may mean that children begin to resist going to the bathroom or withhold stool.u003csupu003eu003ca href=u0022#fn7u0022u003e[7]u003c/au003eu003c/supu003eu003cbru003eCIC in children can arise due to a number of different factors, such as a low-fiber diet and or taking certain medications, that may interact with one another.u003csupu003eu003ca href=u0022#fn8u0022u003e[8]u003c/au003eu003c/supu003e While the condition cannot be cured, it can be treated. Treatment options include laxatives and enemas, as well as a special individualized diet. Children with CIC may be treated by teams of specialists including gastroenterologists, colorectal surgeons, and urologists.u003csupu003eu003ca href=u0022#fn9u0022u003e[9]u003c/au003eu003c/supu003e

u003cstrongu003eDo people with CIC need to be hospitalized??u003c/strongu003e

People with CIC do not need to be hospitalized in most cases. Treatment procedures such as management of fecal impaction, use of laxatives, the administration of enemas, biofeedback therapy, and the manual management of minor rectal prolapse can all be done as outpatient procedures or at home.u003csupu003eu003ca href=u0022#fn10u0022u003e[10]u003c/au003eu003c/supu003eu003cbru003eu003cstrongu003eHoweveru003c/strongu003e, complications that may arise from CIC, such as moderate or severe rectal prolapse and rectocele may need surgical treatment, and this will involve hospitalization.u003csupu003eu003ca href=u0022#fn11u0022u003e[11]u003c/au003eu003ca href=u0022#fn12u0022u003e[12]u003c/au003eu003c/supu003e In very rare cases, people with chronic idiopathic constipation related to obstruction or slow transit may need surgery to remove a portion of the sigmoid colon.u003csupu003eu003ca href=u0022#fn13u0022u003e[13]u003c/au003eu003ca href=u0022#fn14u0022u003e[14]u003c/au003eu003c/supu003e

u003cstrongu003eAre there any home remedies that can help manage chronic idiopathic constipation?u003c/strongu003e

Taking steps to manage chronic idiopathic constipation at home is possible, and home management often accompanies medical treatment.u003cbru003eWeight management, plentiful fluid intake, and regular exercise are important in preventing severe constipation. Eating a diet high in fiber is also helpful in most cases. Although it is anecdotally believed that hot coffee beverages can stimulate bowel movements, this has not been conclusively scientifically established.u003csupu003eu003ca href=u0022#fn15u0022u003e[15]u003c/au003eu003c/supu003eu003cbru003eu003cbru003eSome people with CIC may find following a u003cstrongu003elow FODMAPu003c/strongu003e diet helpful, as it can reduce bloating, flatulence and cramps, as well as diarrhea or constipation. FODMAP stands for “Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols”, short-chain carbohydrates which are poorly absorbed by the body.u003cbru003eu003cbru003eIt should be noted that a low FODMAP diet is generally considered to be more useful in cases of IBS than CIC.u003cbru003eu003csupu003eu003ca href=u0022#fn16u0022u003e[16]u003c/au003eu003c/supu003e u003cstrongu003eBecause FODMAP can become complicated, people who are considering it as a method of managing CIC or IBS should consult a dietitian first.u003c/strongu003e

u003cstrongu003eWhat is biofeedback?u003c/strongu003e

Biofeedback is a method by which people can learn to control bodily processes that were previously believed to be involuntary or out of their control. Biofeedback can be used to treat symptoms, as well as boost overall wellness. It should be noted that, although it is non-invasive, painless, and usually free of side effects,u003csupu003eu003ca href=u0022#fn17u0022u003e[17]u003c/au003eu003c/supu003e biofeedback needs to be done by a qualified therapist and requires input and effort from the person receiving biofeedback as treatment.u003csupu003eu003ca href=u0022#fn18u0022u003e[18]u003c/au003eu003c/supu003eu003cbru003eu003cbru003eIn people affected by constipation, biofeedback is concentrated on learning to voluntarily relax the muscles that govern the opening and closing of the anal sphincter muscles.u003csupu003eu003ca href=u0022#fn17u0022u003e[17]u003c/au003eu003c/supu003e The process uses a computer, special sensors that are placed inside the body, and verbal reinforcement and encouragement from the therapist. It is usually completely painless.u003cbru003eu003cbru003eIn biofeedback, sensors measure electrical currents produced by the activity of muscles in the affected areas. These currents are displayed as information on a computer monitor. Being able to see muscle movement in an easily-understandable form like this helps the affected person to visualize what is happening inside their body.u003csupu003eu003ca href=u0022#fn19u0022u003e[19]u003c/au003eu003c/supu003e In this way, they can learn what is happening and how to control it.

## Question: What is Chronic Idiopathic Constipation?

## Answer:

Chronic Idiopathic⁣ Constipation (CIC) is a common functional gastrointestinal ‌disorder characterized by persistent⁣ difficulty passing bowel movements. It is defined as constipation that lasts for at least three months and is not caused by an underlying‍ medical condition or medication use.

### Key Features of Chronic⁣ Idiopathic Constipation:

* ⁢**Infrequent​ bowel movements:** Less than 3 bowel movements per week

* **Hard,⁤ dry, or lumpy stools**

* **Straining or‌ difficulty evacuating stools**

* ⁣**Incomplete bowel movements**

* **Abdominal pain, bloating, or discomfort**

* **Feeling of fullness or blockage in the rectum**

* **Exessive flatulence**

### Causes:

The exact cause of CIC is⁣ unknown, but it is believed to involve⁣ a combination of factors affecting bowel motility and stool consistency:

* **Slowed colonic transit time:** ‍Food takes longer to move through the ⁣colon, leading⁣ to dehydration of stools.

* **Muscle dysfunctions:** Weak pelvic floor muscles or rectal disorganization ‍can hinder ‍stool expulsion.

* **Dietary factors:** Low fiber intake, inadequate fluid ⁢consumption, and poor dietary habits.

* **Hormonal imbalances:** ⁢Changes in hormone levels, such as‍ during pregnancy ⁢or menopause, can affect bowel function.

* **Lifestyle‍ factors:** Physical‍ inactivity, stress, and irregular daily routines​ can contribute ⁢to constipation.

### Diagnosis:

CIC is diagnosed through a comprehensive evaluation that includes:

* Patient’s medical history

* Physical examination

* Rectal examination

* Blood tests to rule out other medical conditions

*‌ Colonoscopy or other‌ imaging tests⁤ may be necessary to exclude structural abnormalities.

### Management:

Treatment for CIC involves lifestyle modifications and‍ dietary interventions:

* **High-fiber diet:** Adding ⁤soluble and insoluble fiber to the diet​ promotes regular bowel movements.

* **Adequate⁢ fluid ⁢intake:** Drinking plenty of fluids softens stools and eases passage.

*‌ **Regular exercise:** Physical⁣ activity stimulates ⁣bowel motility.

* **Bowel training:** ‍Establishing a regular‌ time for⁣ bowel movements and using strategies to facilitate defecation.

* **Medications:** Laxatives, stool softeners, and prokinetic agents may be prescribed if lifestyle changes alone are insufficient.

### Prevention:

Some measures to help​ prevent CIC include:

* Maintaining a balanced diet rich in fruits, vegetables, and ​whole grains

* Staying adequately ⁣hydrated

* Engaging​ in regular physical activity

* Establishing a regular bowel routine

* Managing stress

One comment

  1. Chronic idiopathic constipation isn’t even a definable diagnosis. the patient may or may not have the condition that is referred to as “idiopathic constipation” and it may not even be chronic. the patient has not been evaluated to d/o other sources for their constipation.
