Shigellosis, known historically as dysentery, is an infection of the intestines caused by Shigella bacteria. [1] [3] Symptoms generally start one to two days after exposure and include diarrhea, fever, abdominal pain, and feeling the need to pass stools even when the bowels are empty. [1] The diarrhea may be bloody. [1]
The direct (primary) symptom is a lack of control over bowel contents which tends to worsen without treatment. Indirect (secondary) symptoms, which are the result of leakage, include pruritus ani (an intense itching sensation from the anus), perianal dermatitis (irritation and inflammation of the skin around the anus), and urinary tract ...
Chronic campylobacteriosis features a long period of sub-febrile temperature and asthenia; eye damage, arthritis, endocarditis may develop if infection is untreated. Occasional deaths occur in young, previously healthy individuals because of blood volume depletion (due to dehydration), and in people who are elderly or immunocompromised.
Many of the symptoms are due to malabsorption of nutrients due to the effects of bacteria which either metabolize nutrients or cause inflammation of the small bowel, impairing absorption. The symptoms of bacterial overgrowth include nausea, flatus, [5] constipation, [6] bloating, abdominal distension, abdominal pain or discomfort, diarrhea, [7 ...
Sapovirus is a genetically diverse genus of single-stranded positive-sense RNA, non-enveloped viruses within the family Caliciviridae. [1] [2] Together with norovirus, sapoviruses are the most common cause of acute gastroenteritis (commonly called the "stomach flu" although it is not related to influenza) in humans and animals.
Signs and symptoms usually begin 12–72 hours after contracting the infectious agent. [15] If due to a virus, the condition usually resolves within one week. [18] Some viral infections also involve fever, fatigue, headache and muscle pain. [18] If the stool is bloody, the cause is less likely to be viral [18] and more likely to be bacterial. [19]

Biofeedback has been shown to improve symptoms (improved frequency of bowel movements, reduced straining) and also reduce need for laxatives, [16] and patients stop needing to self-digitate. [25] Biofeedback can successfully treat abnormal contraction and relaxation of muscles in the anorectum during defecation. [ 25 ]
