or '''irregularity''', is a condition of the
Digestive System where a person (or animal) experiences hard
Feces that are difficult to
Egest ; it may be extremely painful, and in severe cases (''fecal impaction'') lead to symptoms of
Bowel Obstruction . '''Obstipation''' refers to severe constipation. Causes of constipation may be
Diet ary,
Hormonal , anatomical, a side effect of medications, or an illness or disorder. Treatment is with a change in dietary and
Exercise habits.

Constipation is one of the most common digestive complaints. It varies greatly between different people, as each person’s bowel movements differ. Most cases of constipation are caused by a low fiber diet or dehydration. Constipation is most common in children and older people, and affects women more than men. One in 200 women have severe, continuous constipation and it is most common before a period and in pregnancy.

Over 6 million people in the UK at any time find it painful or difficult to pass stools. The pain can be even worse if you have hemorrhoids or anal fissure.

In common constipation, the stool is hard and difficult to pass. Usually, there is an infrequent urge to void. Straining to pass stool may cause
Hemorrhoid s and
Anal Fissure s. In later stages of constipation, the abdomen may become distended and diffusely tender and
Cramp y, occasionally with enhanced
Bowel Sounds . In addition, constipation is a most painful, disturbing, and somewhat embarrassing experience.
The definition of constipation includes the following:
- infrequent bowel movements (typically 3 times per week)
- difficulty during defecation (straining during more than 25% of bowel movements or a subjective sensation of hard stools), or
- the sensation of incomplete bowel evacuation. http://www.emedicine.com/med/topic2833.htm
Medical authorities accept wide variations in toilet frequency as long as this does not cause any other symptoms. Defecating depends on dietary habits, exercise, fluid intake, and various other factors.
Severe cases ("fecal impaction") may feature symptoms of bowel obstruction (
Vomiting , very tender abdomen) and "paradoxical diarrhea", where soft stool from the small intestine bypasses the impacted matter in the
Colon .
Constipation in children can lead to
Soiling (
Enuresis and
Encopresis ).
The diagnosis is essentially made from the patient's description of the symptoms. Bowel movements that are difficult to pass, very firm, or made up of small rabbit-like pellets qualify as constipation, even if they occur every day. Other symptoms related to constipation can include bloating, distention, abdominal pain, or a sense of incomplete emptying.
Inquiring about dietary habits may reveal a low intake of dietary fiber or inadequate amounts of fluids. Constipation as a result of poor ambulation or immobility should be considered in the elderly. Constipation may arise as a
Side Effect of medications (especially
Antidepressants and
Opiates ). Rarely, other symptoms suggestive of
Hypothyroidism may be elicited.
During
Physical Examination , ''scybala'' (manually palpable lumps of stool) may be detected when a diagnostician presses on the abdomen.
Rectal Examination gives an impression of the anal sphincter tone and whether the lower rectum contains any feces or not; if so, then suppositories or
Enemas may be considered. Otherwise, oral medication may be required. Rectal examination also gives information on the consistency of the stool, presence of hemorrhoids, and whether any tumors or abnormalities are present.
X-ray s of the abdomen, generally only performed on hospitalized patients, may reveal impacted fecal matter in the colon, and confirm or rule out other causes of similar symptoms.
Chronic constipation (symptoms present for more than 3 months at least 3 days per month) associated with abdominal discomfort is often diagnosed as
Irritable Bowel Syndrome (IBS) when no obvious cause is found. Physicians caring for patients with chronic constipation are advised to rule out obvious causes through normal testing.Longstreth GF, Thompson WG, Chey WD, Houghton LA, Mearin F, Spiller RC. Functional bowel disorders. ''Gastroenterology'' 2006;130:1480–1491. PMID 16678561.
The main causes of constipation include:
- Hardening of the feces
- --- Improper Mastication of food
- --- Insufficient intake of Dietary Fiber
- --- Dehydration
- --- Medication, e.g. Dihydrocodeinone , Diuretic s and those containing Iron , Calcium , Aluminium
- Paralysis or slowed transit, where Peristaltic Action is diminished or absent, so that feces are not moved along
- --- Hypothyroidism (slow-acting Thyroid Gland )
- --- Hypokalemia
- --- Injured Anal Sphincter (patulous Anus )
- --- Medications, such as Loperamide , Opioid s (e.g. Codeine & Morphine ) and certain Antidepressant s
- --- Severe illness due to other causes; occasionally colds or flu
- --- Acute Porphyria (a very rare inherited condition)
- --- Lead Poisoning
- Dyschezia syn(usually the result of suppressing defecation)
- Constriction, where part of the Intestine or Rectum is narrowed or blocked, not allowing feces to pass
- --- Stenosis (Strictures)
- --- Diverticula
- --- Tumor s, either of the bowel or surrounding tissues
- --- Retained Foreign Body
- Psychosomatic constipation, based on anxiety or unfamiliarity with surroundings.
- --- Functional Constipation
- --- Constipation-predominant Irritable Bowel Syndrome , characterized by a combination of constipation and abdominal discomfort and/or painCaldarella MP, Milano A, Laterza F, Sacco F, Balatsinou C, Lapenna D, Pierdomenico SD, Cuccurullo F, Neri M.

In people without medical problems, the main intervention is to increase the intake of fluids (preferably
Water ) and
Dietary Fiber . The latter may be achieved by consuming more
Vegetable s and
Fruit and
Whole Meal Bread , and by adding
Linseed s to one's diet. The routine non-medical use of laxatives is to be discouraged as this may result in bowel action becoming dependent upon their use. Enemas can be used to provide a form of mechanical stimulation.
In alternative and traditional medicine,
Colonic Irrigation , enemas, exercise, diet and herbs are used to treat constipation.
See Also: laxative
Laxative s may be necessary in people in whom dietary intervention is not effective or is inappropriate.
Constipation that resists all the above measures requires physical intervention. ''Manual disimpaction'' (the physical removal of impacted stool) is done by patients who have lost control of their bowels secondary to spinal injuries. Manual disimpaction is also used by physicians and nurses to relieve rectal impactions. Finally, manual disimpaction can occasionally be done under
Sedation or a
General Anesthetic —this avoids pain and loosens the anal sphincter.
Many of the products are widely available
Over-the-counter .
Enema s and
Clyster s are a remedy occasionally used for hospitalized patients in whom the constipation has proven to be severe, dangerous in other ways, or resistant to laxatives.
Sorbitol ,
Glycerin and
Arachis Oil Suppositories can be used. Severe cases may require
Phosphate solutions introduced as enemas.
Constipation is usually easier to prevent than to treat. The relief of constipation with osmotic agents, i.e. lactulose,
Polyethylene Glycol (PEG), or magnesium salts, should immediately be followed with prevention using increased fiber (fruits and vegetables) and a nightly decreasing dose of osmotic laxative. With continuing narcotic use, for instance, nightly doses of osmotic agents can be given indefinitely (without harm) to cause a daily bowel movement.
Recent controlled studies have questioned the role of physical exercise in the prevention and management of chronic constipation, while exercise is often recommended by published materials on the subject.
In various conditions (such as the use of
Codeine or
Morphine ), combinations of hydrating (e.g.
Lactulose or
Glycols ), bulk-forming (e.g.
Psyllium ) and stimulant agents may be necessary to prevent constipation.
Hibernating animals can experience
Tappen s that are usually expelled in the spring. For example, bears eat many foods that create a "rectal plug" before hibernation.
