Intestinal villi (sg.: villus) are small, finger-like projections that extend into the lumen of the small intestine. Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border. Each of these microvilli are about 1 ...
The cause of this wide range in severity of symptoms is not fully known but the intestinal flora of the infected host may play a role. [7] [8] Diarrhoea is less likely to occur in people from developing countries. [7] Symptoms typically develop 9–15 days after exposure, [9] but may occur as early as one day. [5]
Other names: Tropical enteropathy or Environmental enteric dysfunction: Histological evidence of enteropathy (inflammatory infiltrate, villus blunting) seen in this intestinal biopsy from a child with malnutrition. [1] Specialty: Gastroenterology: Symptoms: Asymptomatic (most common), altered stool consistency, increased stool frequency, weight ...
Other names: Severe immune-mediated enteropathy, Immune-mediated protracted diarrhea of infancy: Histological evidence of enteropathy (inflammatory infiltrate, villus blunting) seen in this intestinal biopsy from a child with malnutrition. Specialty: Immunology Gastroenterology: Symptoms: Diarrhea, and autoimmune damage to the intestinal mucosa ...
Viruses cause about 70% of episodes of infectious diarrhea in the pediatric age group. [13] Rotavirus is a less common cause in adults due to acquired immunity. [27] Norovirus is the cause in about 18% of all cases. [28] Generally speaking, viral gastroenteritis accounts for 21–40% of the cases of infectious diarrhea in developed countries. [29]
Enteritis is inflammation of the small intestine. It is most commonly caused by food or drink contaminated with pathogenic microbes, [1] such as Serratia, but may have other causes such as NSAIDs, radiation therapy as well as autoimmune conditions like coeliac disease. Symptoms include abdominal pain, cramping, diarrhoea, dehydration, and fever ...
The major issue results from this intestinal blood loss which can lead to iron-deficiency anemia in moderate to heavy infections. Other common symptoms include epigastric pain and tenderness, nausea, exertional dyspnea, pain in lower extremities and in joints, sternal pain, headache, fatigue, and impotence. [5] Death is rare in humans ...
Some types of helminths and protozoa are classified as intestinal parasites that cause infection—those that reside in the intestines. These infections can damage or sicken the host (humans or other animals). If the intestinal parasite infection is caused by helminths, the infection is called helminthiasis.
