The term ‘stomach bug’ is commonly used in conversations to describe an onset of discomfort, in the stomach and intestines. What exactly do people mean when they refer to a ‘stomach bug’? In this article we will delve into the details of this ailment, including its symptoms, treatment options and other important factors.
Common Understanding Of 'Stomach Bug'
When people mention a ‘stomach bug’ they are usually referring to an illness that affects the stomach and intestines. It’s a term that is often used interchangeably with phrases like ‘tummy bug’ or ‘gastro bug’. This condition is typically characterised by symptoms such as nausea, vomiting, diarrhoea and abdominal cramping.
Definition Of A 'Stomach Bug'
In medical terms, a ‘stomach bug’ is formally known as gastroenteritis. Gastroenteritis is an inflammation of the stomach and intestines primarily caused by viruses. However, bacteria, parasites, food poisoning and certain antibiotics can also be culprits. The common viral causes include norovirus and rotavirus.
Common Symptoms
If you have a stomach bug you might experience the following:
Nausea or vomiting
Diarrhoea
Stomach cramps or pain
Mild fever
Loss of appetite
Muscle aches
These symptoms usually appear within one to two days after coming into contact, with the cause and can last for days up to about a week.
When to Seek Medical Attention? Worsening Symptoms
While most cases of gastroenteritis are mild and resolve on their own there are signs that indicate that you should see a doctor:
Persistent vomiting that makes it difficult to keep liquids down
Signs of dehydration, such as feeling excessively thirsty, having dark yellow urine, dry skin, and dizziness or feeling faint
Severe abdominal pain
Seeing blood in your stools or vomit
Having a high fever above 38.5°C
Experiencing symptoms that persist for more than a week
Options for Treatment
The primary treatment for a stomach bug is supportive care:
Hydration: It’s important to stay hydrated. Oral rehydration solutions, available at pharmacies, can help replenish lost fluids and electrolytes.
Diet: Consuming bland foods like toast, rice, or bananas can be easier on the stomach. It’s advisable to avoid dairy, spicy foods, and caffeine until a recovery has been made
Rest: Giving the body ample rest can speed up the healing process.
Medication: Over-the-counter pain relievers and anti-diarrheaol can alleviate some symptoms, but it’s essential to use them as directed and ensure they don’t worsen any stomach upset.
Telehealth Consultations for Dealing With 'Stomach Bugs'
With the rise of telehealth services, many wonder if a stomach bug can be effectively diagnosed and treated remotely. In many cases, a telehealth consultation can be beneficial. A healthcare professional can assess symptoms, provide guidance on treatment, and determine if an in-person visit is necessary. However, when severe symptoms or complications arise a physical examination might be more appropriate.
Other Factors to Consider
Transmissibility: Stomach bugs, especially those caused by viruses like norovirus, are highly contagious. They can spread through contaminated food, water, surfaces, or direct contact with an infected person.
Exclusion Criteria: If diagnosed with a contagious form of gastroenteritis, it’s recommended to stay away from work, school, or public places until at least 48 hours after the last symptoms have subsided. This precaution helps prevent spreading it to others.
Prevention: Regular hand-washing with soap and water, especially after using the toilet and before eating, is the best defence. Avoiding close contact with infected individuals and ensuring food is cooked thoroughly can also reduce the risk.
The Rotavirus Vaccine: Given orally to infants, it plays a pivotal role in preventing severe diarrhoea and vomiting caused by rotavirus. While common side effects are mild, including temporary diarrhoea, vomiting, fever, and irritability, rare side effects like intussusception (a form of bowel blockage) and severe allergic reactions can occur. However, the benefits of the vaccine, in terms of reducing severe rotavirus cases and hospitalisations, far outweigh these risks.
‘Stomach bugs’, or gastroenteritis, while often mild and self-limiting, can be a source of significant discomfort. Recognising the symptoms and understanding when to seek medical attention is crucial. With the right care, most individuals recover swiftly. However, due to its contagious nature, it’s essential to take precautions to prevent its spread, ensuring the well-being of both the individual and the wider community.
