It causes increased levels of amniotic fluid during pregnancy (polyhydramnios) and intestinal obstruction in newborn babies. Newborns present with bilious or non-bilous vomiting (depending on where in the duodenum the obstruction is) within the first 24 to 48 hours after birth, typically after their first oral feeding.
Bowel obstruction, also known as intestinal obstruction, is a mechanical or functional obstruction of the intestines which prevents the normal movement of the products of digestion. [2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
Intestinal atresia is any congenital malformation of the structure of the intestine that causes bowel obstruction. The malformation can be a narrowing , absence or malrotation of a portion of the intestine. These defects can either occur in the small or large intestine.
Ileosigmoid knotting typically manifests as sudden, severe abdominal pain.It can quickly worsen into sigmoid colon and ileum gangrene, which can lead to potentially fatal side effects like sepsis, generalized peritonitis, electrolyte imbalance, and dehydration. [4]
Obstructed defecation is one of the causes of chronic constipation. [22] ODS is a loose term, [20] consisting of a constellation of possible symptoms, [7] caused by multiple, complex [23] and poorly understood [24] disorders which may include both functional and organic disorders. [18]
The narrow mesentery predisposes some cases of malrotation to midgut volvulus, a twisting of the entire small bowel that can obstruct the mesenteric blood vessels leading to intestinal ischemia, necrosis, and death if not promptly treated. The fibrous Ladd's bands can constrict the duodenum, leading to intestinal obstruction.
Neonatal bowel obstruction (NBO) or neonatal intestinal obstruction is the most common surgical emergency in the neonatal period. [1] It may occur due to a variety of conditions and has an excellent outcome based on timely diagnosis and appropriate intervention .
However, instances with symptoms and signs of a bowel obstruction occur, but with the absence of a mechanical obstruction, mainly in acute colonic pseudo-obstruction, Ogilvie's syndrome. [3] In 2023 the US FDA reported gastrointestinal ileus as an adverse effect of the medication semaglutide , with frequency and causal relationship unknown.
