About bowel infection

A bowel infection, also known as gastroenteritis or enteritis, refers to the inflammation of the intestines, usually caused by an infection from bacteria, viruses, or parasites. Common symptoms of a bowel infection include diarrhoea, abdominal pain, cramping, nausea, vomiting, and fever. Bacterial infections, such as those caused by Salmonella, Escherichia coli (E. coli), and Campylobacter, are often contracted through contaminated food or water. Viral infections like norovirus and rotavirus are highly contagious and typically spread through contact with infected individuals or surfaces. Parasitic infections, although less common, can be contracted from contaminated water sources. Most bowel infections resolve on their own with supportive care, including staying hydrated and resting. However, in severe cases, particularly when dehydration sets in or the infection becomes widespread, medical intervention may be needed. Preventing bowel infections involves practising good hygiene, such as frequent handwashing and avoiding contaminated food or water.

You should consult a doctor for a bowel infection if:

  • Severe dehydration: Symptoms of dehydration, such as dry mouth, excessive thirst, dizziness, reduced urination, or dark urine.
  • Blood in stool or vomit: If you notice blood in your stool or vomit, it could indicate a more serious infection that needs medical evaluation.
  • High fever: A persistent fever above 101°F (38.3°C) that doesn’t improve with rest or fluids.
  • Severe abdominal pain: Intense or persistent abdominal pain that doesn’t subside with over-the-counter pain relief.
  • Prolonged symptoms: If diarrhoea or vomiting lasts for more than 2-3 days without improvement.
  • Weak immune system: If you have a weakened immune system due to a chronic condition, chemotherapy, or other factors.
  • Unexplained weight loss: Unintended weight loss or difficulty maintaining food intake.

Bowel infections can be classified based on the type of organism causing them. Here are the common types:

  • Bacterial bowel infections: Caused by bacteria like Salmonella, E. coli, Shigella, Campylobacter, and Clostridium difficile (C. diff). These infections are often linked to contaminated food, water, poor hygiene or overuse of antibiotics (C. diff). Symptoms typically include diarrhoea (sometimes bloody), abdominal cramps, nausea, fever, and vomiting.
  • Viral bowel infections: Viruses such as norovirus, rotavirus, and adenovirus cause viral gastroenteritis. These are highly contagious and often spread through contact with infected people, contaminated surfaces, or food. Common symptoms include watery diarrhoea, vomiting, stomach cramps, and fever.
  • Parasitic bowel infections: Caused by parasites like Giardia lamblia, Entamoeba histolytica, and Cryptosporidium. These are usually contracted from contaminated water or food, especially in areas with poor sanitation. Symptoms include prolonged diarrhoea, weight loss, mucus and blood in stool, bloating, and fatigue.
  • Fungal bowel infections: Though rare, in individuals with weakened immune systems, fungi like Candida can affect the intestines, leading to digestive issues, though these cases are uncommon.

Bowel infections are caused by the invasion of harmful microorganisms including bacteria, viruses, or parasites into the intestines. This leads to inflammation and digestive issues. Common causes include:

  • Contaminated food or water: Eating undercooked, spoiled, or improperly handled food and drinking unclean or untreated water.
  • Poor hygiene: Inadequate handwashing after using the toilet or before eating can easily spread infection.
  • Infected individuals: Viral infections like norovirus spread rapidly through person-to-person contact or by touching contaminated surfaces.
  • Travel: Consuming local food or water in regions with poor sanitation can increase the risk of parasitic and bacterial infections often called traveller’s diarrhoea.
  • Antibiotic use: Overuse or misuse of antibiotics can disrupt the natural balance of gut bacteria.
  • Weakened immune system: Individuals with weakened immunity are more vulnerable to bowel infections from even minor exposures.

The symptoms of a bowel infection can vary depending on the cause, but common signs include:

  • Diarrhoea: Frequent, loose, or watery stools which may contain mucus or blood in case of bacterial or parasitic infections.
  • Abdominal pain: Discomfort or cramping in the stomach area, often relieved after a bowel movement.
  • Nausea and vomiting: Feeling sick or vomiting, particularly with viral and bacterial infections.
  • Fever: A mild to high temperature, especially in bacterial or severe viral infections.
  • Bloating and gas: A feeling of fullness or swelling in the abdomen due to trapped gas.
  • Loss of appetite: Reduced desire to eat because of nausea, pain, or general unwellness.
  • Fatigue and weakness: Feeling tired and run down, often due to dehydration and loss of nutrients.
  • Dehydration: Signs include dry mouth, reduced urination, dizziness, and dark-coloured urine, especially with persistent diarrhoea and vomiting.

Yes, many bowel infections are contagious, especially those caused by viruses and certain bacteria. Infections like norovirus, rotavirus, E. coli, and Salmonella can easily spread through contact with infected individuals, contaminated food, water, or surfaces. Good hygiene practices, such as regular handwashing, safe food preparation, and avoiding close contact with infected people, are essential to reduce the risk of catching or passing on a bowel infection.

Yes, bowel infections can often be prevented with simple hygiene and safety practices. Here’s how:

  • Hand hygiene: Especially before eating, after using the toilet, and after handling raw food.
  • Drink clean water: Use filtered, boiled, or bottled water in areas with questionable water quality.
  • Eat well-cooked food: Ensure meats, eggs, and seafood are thoroughly cooked to safe temperatures.
  • Avoid unpasteurised products: Skip raw milk, juices, or dairy products from unknown or untrusted sources.
  • Practise good food hygiene: Wash fruits and vegetables well and avoid cross-contamination in the kitchen.
  • Be cautious when travelling: In high-risk areas, avoid street food, ice cubes, and tap water.
  • Disinfect surfaces: Clean kitchen counters, bathroom surfaces, and communal spaces regularly.
  • Avoid sharing personal items: Such as towels, utensils, or drinking glasses with an infected person.
  • Properly handle leftovers: Store and reheat leftovers safely to prevent bacterial growth.
  • Use probiotics: If suggested by a health practitioner, to maintain healthy gut bacteria.
