What is Acute Bacterial Diarrhoea (ABD)?
Acute bacterial diarrhoea (ABD) is a common and often self-limiting illness characterized by frequent, watery stools, abdominal cramps, and sometimes fever. It is caused by the ingestion of bacteria that infect the gastrointestinal tract, leading to inflammation and disruption of normal bowel function.
Causes of ABD
Several bacteria can cause ABD, including:
- Salmonella: Found in Poultry, eggs, and unpasteurized milk.
- Campylobacter: Found in undercooked poultry, unpasteurized milk, and contaminated water.
- Escherichia coli (E. coli): Found in contaminated food and water, especially raw or undercooked meat.
- Shigella: Spread through contaminated food and water, and person-to-person contact.
- Vibrio cholerae: Found in contaminated water and seafood.
- Clostridium difficile: Often associated with antibiotic use and found in hospitals.
Symptoms of ABD
The symptoms of ABD can vary depending on the specific bacteria causing the infection. Common symptoms include:
- Diarrhoea: Frequent, watery stools, sometimes with blood or mucus.
- Abdominal cramps: Pain or discomfort in the abdomen.
- Fever: Elevated body temperature.
- Nausea and vomiting: Feeling sick to your stomach and throwing up.
- Dehydration: Loss of fluids and electrolytes, leading to weakness, dizziness, and dry mouth.
Diagnosis of ABD
Diagnosing ABD usually involves a combination of:
- Medical history: Discussing your symptoms and recent travel history.
- Physical examination: Checking for signs of dehydration and other symptoms.
- Stool culture: A laboratory test to identify the specific bacteria causing the infection.
Treatment of ABD
Treatment for ABD typically focuses on:
- Rehydration: Replacing lost fluids and electrolytes through oral rehydration solutions (ORS) or intravenous fluids.
- Symptom management: Using anti-diarrheal medications to reduce the frequency of stools and anti-nausea medications to relieve vomiting.
- Antibiotics: In some cases, antibiotics may be prescribed to treat the bacterial infection, especially if the symptoms are severe or if the patient is at risk of complications.
Prevention of ABD
Preventing ABD involves practicing good hygiene and food safety measures:
- Wash your hands frequently: Wash your hands thoroughly with soap and water before eating, after using the toilet, and after handling raw meat or poultry.
- Cook food thoroughly: Ensure meat and poultry are cooked to the appropriate internal temperature to kill bacteria.
- Wash fruits and vegetables: Wash fruits and vegetables thoroughly before eating to remove any contaminants.
- Drink safe water: Avoid drinking water from questionable sources and ensure water is properly treated.
- Avoid cross-contamination: Keep raw meat and poultry separate from other foods to prevent cross-contamination.
Complications of ABD
While ABD is usually a self-limiting illness, complications can occur, especially in young children, older adults, and people with weakened immune systems. These complications include:
- Dehydration: Severe dehydration can lead to electrolyte imbalances, seizures, and even death.
- Hemolytic uremic syndrome (HUS): A serious complication caused by certain strains of E. coli, leading to kidney failure and other Health problems.
- Sepsis: A life-threatening condition caused by the bacteria entering the bloodstream.
When to See a Doctor
It is important to seek medical attention if you experience any of the following:
- Severe dehydration: Signs include excessive thirst, dry mouth, sunken eyes, and decreased urination.
- Bloody diarrhoea: This could indicate a more serious infection.
- High fever: A fever above 101.5°F (38.6°C) could indicate a severe infection.
- Persistent diarrhoea: Diarrhoea lasting more than 3 days could indicate a persistent infection.
- Abdominal pain: Severe or persistent abdominal pain could indicate a complication.
