Patient Success Stories

Thousands of patients have trusted Sydney Gut Clinic to guide their gut health journey.
Here’s what a few of them had to say

Gastroenteritis, commonly referred to as gastro, is an infection that affects the stomach and intestines, causing a range of uncomfortable symptoms. While it’s often associated with children, gastro symptoms in adults are just as common. Gastro can result in distressing symptoms that can interfere with your daily life. Understanding the causes, symptoms, and treatment options can help you manage the condition and recover quickly.

Common gastro symptoms in adults

  • Diarrhoea and vomiting – Diarrhoea and vomiting are the most common and disruptive symptoms of gastro. Whether caused by a viral or bacterial infection, these symptoms can leave you feeling drained and weak. They may occur suddenly and without warning, making it hard to plan daily activities.
  • Abdominal cramps and pain – Gastro symptoms often include abdominal pain, ranging from mild discomfort to sharp, cramp-like pains. The pain may occur without warning and can be accompanied by certain accompanying symptoms like bloating, which often makes the discomfort feel more intense.
  • Nausea and loss of appetite – One of the key indicators of gastro is nausea. This can make eating and drinking challenging for many individuals, and in many cases, individuals experience a sudden loss of appetite. Proper hydration becomes essential during this time, even if eating seems difficult.
  • Fatigue and body aches – Fatigue is a common symptom of gastro, as your body expends energy to fight off the infection. Systemic symptoms such as body aches and tiredness are also common as your body recovers. These symptoms can leave you feeling drained and unable to do daily activities.

What causes gastro in adults?

  • Viral infections – The most frequent cause of gastro in adults is viruses, with norovirus and rotavirus being the leading culprits. These viruses are highly contagious and can spread quickly, particularly in communal settings like schools.
  • Bacterial contamination – Contaminated food, particularly undercooked meat, or poor hygiene practices can potentially lead to bacterial infections such as salmonella or E. coli. These infections can cause gastro symptoms that may last for days.
  • Contaminated water or surfaces – Gastro can also spread through contaminated water or surfaces, especially in environments where hygiene practices aren’t strictly followed. Public places like gyms and offices are common areas where germs can be transmitted.
  • Person-to-person transmission – Person-to-person transmission is another primary way that gastro spreads. The infection can spread through contact with contaminated hands, surfaces, or food, making hand cleanliness critical to preventing its spread.

When to be concerned 

  • Dehydration warning signs – One of the most serious risks of gastro is dehydration. If you experience dizziness, dry mouth, dark urine, or reduced urination, you could be severely dehydrated. It’s crucial to replenish fluids and electrolytes to avoid complications.
  • Symptoms lasting longer than 48 hours – Gastro usually resolves within a few days. If your symptoms persist beyond 48 hours or worsen over time, it’s important to seek medical attention as soon as possible. Prolonged symptoms can indicate a more serious infection or complication.
  • Blood in stool or vomit – If you notice blood in your stool or vomit, this could be a sign of a serious condition, such as an infection or internal injury. Seek medical care immediately if you experience these symptoms, as they may indicate a need for urgent treatment.
  • High fever or severe weakness – A high fever, coupled with severe weakness, may suggest a bacterial infection or other underlying health issues. If these symptoms occur alongside gastro symptoms, contact a healthcare professional, as they may indicate a more serious infection.

Treatment options for gastro in adults

  • Staying hydrated – Hydration is critical when dealing with gastro. Oral rehydration salts (ORS) can help replenish lost fluids and electrolytes, which are essential for recovery. Sip fluids regularly, even if you feel nauseous, to prevent dehydration.
  • Rest and diet adjustments – Rest is very important during recovery. It allows your body to focus on healing. Additionally, dietary changes can help manage symptoms—stick to bland foods such as rice, toast, and crackers, and avoid dairy, caffeine, and alcohol.
  • Probiotics – Taking probiotics can help restore the balance of good bacteria in your gut, aiding digestion and improving your gut health. Also, incorporating probiotics into your diet, either through food or supplements, may help speed up recovery.
  • Medical treatment for severe cases – If your gastro symptoms are severe, your healthcare provider may recommend antibiotics for bacterial infections or intravenous (IV) fluids to treat dehydration. Make sure to always follow your doctor’s advice regarding treatment and recovery.
