Dysentery is a type of gastrointestinal infection characterized by inflammation of the intestines, leading to severe diarrhoea with blood and mucus. While it is more common in developing countries with limited access to clean water and sanitation, it can occur anywhere. Prompt diagnosis and treatment are essential to prevent complications.
Symptoms of Dysentery
The symptoms of dysentery can vary in severity depending on the underlying cause. Common symptoms include:
- Diarrhea with Blood and Mucus: A hallmark of dysentery.
- Abdominal Pain: Cramping or sharp pain in the stomach.
- Fever: Often accompanied by chills.
- Nausea and Vomiting: Common alongside diarrhoea.
- Dehydration Symptoms: Thirst, dry mouth, fatigue, and reduced urination.
- Weakness: General fatigue and loss of appetite.
Causes of Dysentery
Dysentery is primarily caused by infections that lead to inflammation in the intestinal lining. The two main types are:
1. Bacillary Dysentery:
- Caused by bacteria, most commonly Shigella
- Often spreads through contaminated food, water, or poor hygiene.
2. Amoebic Dysentery (Amoebiasis):
- Caused by the parasite Entamoeba histolytica.
- More common in tropical and subtropical regions.
Other causes include:
- Poor sanitation and contaminated drinking water.
- Close contact with an infected person.
- Consumption of undercooked or contaminated food.
Diagnosis of Dysentery
Diagnosing dysentery involves clinical evaluation and laboratory tests:
- Stool Analysis: Identifies the presence of blood, mucus, bacteria, or parasites.
- Blood Tests: Check for signs of infection and dehydration.
- Sigmoidoscopy or Colonoscopy: Rarely used but can confirm inflammation or ulcers in the intestines.
- Imaging Studies: May be performed in severe or complicated cases.
Treatment for Dysentery
Treatment depends on the type and severity of the infection:
1. Rehydration Therapy:
- Oral Rehydration Solutions (ORS): To replace lost fluids and electrolytes.
- Intravenous Fluids: Required in severe cases to prevent dehydration.
2. Medications:
- Antibiotics: For bacterial dysentery (e.g., ciprofloxacin or azithromycin).
- Antiparasitic Drugs: For amoebic dysentery (e.g., metronidazole).
- Antipyretics: To manage fever.
- Probiotics: To restore healthy gut bacteria.
3. Nutritional Support:
- Light Diet: Include easily digestible foods such as rice, bananas, and toast.
- Avoid dairy, spicy foods, and caffeine until symptoms improve.
4. Hygiene and Isolation:
- To prevent the spread, isolate the infected individual and practice good hygiene.
Prevention of Dysentery
- Maintain Cleanliness: Wash hands thoroughly with soap after using the restroom and before meals.
- Safe Drinking Water: Consume only boiled or filtered water.
- Proper Food Hygiene: Avoid raw or undercooked food and unwashed fruits and vegetables.
- Vaccination: In some areas, vaccines are available for certain bacterial causes.
