Pathogenesis (development of disease)
The pathogenesis of constipation is diverse. The following components may occur:
- Disruption of intrinsic (“internal”) motility (movement of the bowel).
- Lack of luminal factors, such as stretching, chemical and tactile stimuli.
- Lack of extrinsic innervation (functional supply of nerve tissue to the organ, i.e., nerve cells; cross-sectional lesions).
- Defecation disorders (disorders of defecation).
- Medication
- Hormones (very rare!, e.g., in the case of a pheochromocytoma).
Primary constipation usually occurs when the colon transit time (transit time through the intestine) is prolonged. This occurs due to a decreased number of contraction waves. The cause is then usually a disorder in the nervous system of the intestine. In addition to this form of constipation, many other different causes (secondary constipation – see below) can be considered. Note: In childhood, 3% of patients in a general pediatric practice and up to 25% in a pediatric gastroenterology consultation have stool problems. However, in 90-95% of affected children, no organic cause is found.
Etiology (Causes)
Biographic causes
- Genetic burden
- Genetic diseases
- Cystic fibrosis (ZF) – genetic disease with autosomal recessive inheritance, characterized by the production of secretions in various organs to be tamed.
- Neurofibromatosis – genetic disease with autosomal dominant inheritance; belongs to the phakomatoses (diseases of the skin and nervous system); three genetically different forms are distinguished:
- Neurofibromatosis type 1 (von Recklinghausen’s disease) – patients develop multiple neurofibromas (nerve tumors) during puberty, which often occur in the skin but also occur in the nervous system, orbita (eye socket), gastrointestinal tract (gastrointestinal tract), and retroperitoneum (space located behind the peritoneum on the back toward the spine); Typical is the appearance of café-au-lait spots (light brown macules) and multiple benign (benign) neoplasms
- [Neurofibromatosis type 2 – characteristic is the presence of bilateral (bilateral) acoustic neuroma (vestibular schwannoma) and multiple meningiomas (meningeal tumors).
- Schwannomatosis – hereditary tumor syndrome]
- Hirschsprung’s disease (MH; synonym: megacolon congenitum) – genetic disease with both autosomal recessive inheritance and sporadic occurrence; disease, which in most cases is the last third of the colon (sigmoid and rectum) of the large intestine affected; belongs to the group of aganglionoses; lack of ganglion cells (“aganglionosis”) in the area of the submucosal plexus or myentericus (Auerbach’s plexus) leads to hyperplasia of the upstream nerve cells, resulting in increased acetylcholine release. The permanent stimulation of the ring muscles thus leads to a permanent contraction of the affected section of the intestine.MH is relatively common at 1: 3,000 – 1: 5,000 births, boys are affected up to four times more often than girls. [paradoxical diarrhea (diarrhea); diarrhea alternating with constipation.]
- Porphyria or acute intermittent porphyria (AIP); genetic disease with autosomal dominant inheritance; patients with this disease have a 50 percent reduction in the activity of the enzyme porphobilinogen deaminase (PBG-D), which is sufficient for porphyrin synthesis. Triggers of a porphyria attack, which can last a few days but also months, are infections, drugs or alcohol.The clinical picture, of these attacks presents as acute abdomen or neurological deficits, which can take a lethal course. The leading symptoms of acute porphyria are intermittent (occasionally or chronically) neurological and psychiatric disturbances. Autonomic neuropathy is often in the foreground, causing abdominal colic (acute abdomen), nausea (nausea), vomiting or constipation, as well as tachycardia (heartbeat too fast: > 100 beats per minute) and labile hypertension (high blood pressure).
