Dysentery

From WikiMD's Wellness Encyclopedia

Dysentery is a severe intestinal infection, causing abdominal pain and diarrhea with blood or mucus. The intestinal infection "'dysentery"' is marked by stomach pain, diarrhea with blood or mucus, and other gastrointestinal symptoms. It is often caused by bacteria, parasites, or viruses and, if left untreated, can result in severe dehydration and problems. This article provides a thorough description of dysentery, including its causes, symptoms, treatment options, and preventative measures.

Dysentery Causes[edit | edit source]

The primary infectious agents that cause dysentery are bacterial and parasitic.

Bacterial dysentery[edit | edit source]

The "'Shigella"' bacteria produce Bacterial dysentery, also known as "'bacillary dysentery"' or "'shigellosis"'. This kind of dysentery is more prevalent in developing nations with poor sanitation and congested living situations.

Dysentery due to parasites[edit | edit source]

The single-celled parasite "Entamoeba histolytica" causes parasitic dysentery, sometimes known as "amoebic dysentery". In tropical and subtropical locations, where the parasite is widespread, this form of dysentery is more prevalent.

Indicators[edit | edit source]

Typically, the onset of dysentery symptoms occurs within one to three days after infection and can include:

  • Abdominal pain and cramping
  • Diarrhea accompanied by blood and/or mucous
  • Fever
  • sickness and vomiting
  • Dehydration
  • Fatigue
  • Weight reduction

Complications such as severe dehydration, electrolyte imbalances, and organ damage can occur in extreme cases.

Diagnose[edit | edit source]

A thorough medical history and physical examination, together with laboratory tests to identify the causal agent, are required to diagnose dysentery. Collecting and analyzing stool samples for the presence of germs or parasites is possible. In addition to blood testing and imaging examinations, it may be necessary to determine the infection's severity and rule out other potential explanations of the symptoms.

Therapy[edit | edit source]

Dysentery is treated differently based on the origin and severity of the infection.

Bacterial dysentery[edit | edit source]

Antibiotics, such as ciprofloxacin, azithromycin, or ceftriaxone, are commonly used to target the specific "Shigella" species causing bacterial dysentery. In addition to antibiotics, replacement of fluids and electrolytes lost due to diarrhea requires rehydration therapy.

Dysentery due to parasites[edit | edit source]

Antiparasitic drugs, such as metronidazole or tinidazole, are used to eliminate the "Entamoeba histolytica" parasite that causes parasitic diarrhea. Similarly with bacterial dysentery, individuals with severe diarrhea require rehydration therapy.

Prophylaxis[edit | edit source]

Maintaining adequate hygiene and sanitation practices is essential for preventing dysentery, especially in locations where the infection is widespread. Important preventive measures consist of:

  • Hand-washing with soap and water, especially after using the restroom and prior to food preparation and consumption.
  • Consuming only safe, treated water and avoiding raw or uncooked food as well as food prepared with polluted water can prevent illness.
  • Using suitable sanitary facilities, such as well-maintained latrines, and avoiding pooping in the open
  • ensuring food is completely cooked and safely stored
  • Vaccination is recommended for tourists traveling high-risk locations (if applicable)
