What is Dysentery? Causes, Signs and symptoms, Diagnosis and treatment.

Summary

Dysentery is an intestinal inflammation, causing severe diarrhea with mucus or blood, often resulting from poor sanitation. Each year, millions are affected, particularly children under five. It is caused by bacteria like Shigella or parasites like Entamoeba histolytica. Symptoms include frequent diarrhea, fever, abdominal pain, and dehydration. Diagnosis involves tests like stool and blood exams. Treatment varies from hydration to antibiotics or antiparasitic drugs, depending on the cause. Mild cases usually resolve with hydration, while severe cases require more intensive care, such as IV fluids or specific medications to treat the infection.

Takeaways

• 😀 Dysentery is an intestinal inflammation, primarily of the colon, that can lead to severe symptoms like cramps, diarrhea with mucus or blood, and can be fatal if untreated.
• 😀 Each year, between 120 million and 165 million cases of Shigella infection occur globally, with 1 million resulting in fatalities, mostly affecting children under five years old in developing countries.
• 😀 Poor sanitation and contaminated food, water, or physical contact are the main causes of dysentery, often due to shigellosis or amoebic dysentery.
• 😀 The primary symptom of dysentery is frequent diarrhea with blood, mucus, or pus. Other symptoms include fever, abdominal pain, bloating, and fatigue.
• 😀 Diagnosing dysentery involves tests such as blood tests, stool tests, and potentially sigmoidoscopy or colonoscopy to identify the cause of the infection.
• 😀 If the infection is identified as Shigella or Entamoeba histolytica, treatment options will vary depending on the severity of the symptoms.
• 😀 Hydration is crucial for treating dysentery, and intravenous fluids may be necessary for severe cases of dehydration due to diarrhea and vomiting.
• 😀 Mild dysentery may resolve on its own, especially in developed countries with good sanitation, but hydration remains important.
• 😀 For amoebic dysentery, amoebicidal medications are used to treat Entamoeba histolytica, ensuring the amoeba does not survive after symptoms resolve.
• 😀 A combination of antibiotic and amoebicidal medications may be used if lab results are unclear or if symptoms are severe.

Q & A

What is dysentery and how does it affect the body?

Dysentery is an intestinal inflammation, primarily affecting the colon. It causes symptoms like severe diarrhea, often containing blood or mucus, stomach cramps, and dehydration. Without proper hydration, it can be fatal.

How many cases of Shigella infection occur annually worldwide?

Each year, there are between 120 million and 165 million cases of Shigella infection, with approximately 1 million fatalities. Over 60% of these deaths are in children under the age of five in developing countries.

What causes dysentery, and how does it spread?

Dysentery is primarily caused by Shigella bacteria or Entamoeba histolytica amoebas, often due to poor sanitation. It spreads when individuals come into contact with fecal matter, typically through contaminated food, water, or physical contact.

What are the main symptoms of dysentery?

The main symptom is frequent, liquid diarrhea mixed with blood, mucus, or pus. Additional symptoms include fever, chills, abdominal pain, bloating, flatulence, loss of appetite, weight loss, fatigue, and dehydration.

How is dysentery diagnosed?

Dysentery is diagnosed through a physical exam and a review of the patient's medical history. Additional tests may include blood tests, stool tests, and procedures like sigmoidoscopy or colonoscopy to examine the colon.

What treatments are available for mild dysentery?

Mild dysentery, often seen in developed countries, may resolve without treatment. However, it is important for the patient to stay hydrated. Antibiotics are used in more severe cases.

How is amoebic dysentery treated?

Amoebic dysentery is treated with antiprotozoal medications to target Entamoeba histolytica. If necessary, a combination of antibiotics and amoebic medications may be used, especially if lab results are unclear.

Why is hydration crucial for dysentery patients?

Hydration is vital because dysentery causes severe diarrhea and vomiting, leading to dehydration. Patients should drink fluids, and in severe cases, intravenous (IV) fluids may be administered to prevent fatal dehydration.

What role does sanitation play in preventing dysentery?

Sanitation is crucial in preventing dysentery. Poor sanitation, including contaminated water and food, is a major factor in the spread of Shigella and amoebic infections, especially in developing countries.

How can travelers contribute to the spread of dysentery?

Travelers may contract dysentery in regions with poor sanitation and unknowingly spread the infection. Providing travel history to healthcare providers is essential for proper diagnosis and treatment.
