How Long Does a Typical Stomach Bug Last?
Most stomach bugs, also known as viral gastroenteritis, are caused by viruses like norovirus or rotavirus. These infections usually last 24 to 72 hours. Symptoms often come on suddenly and peak within the first day. For most people, the worst of the illness resolves in a few days, especially with rest and hydration. However, recovery time can vary based on factors like age, immune system strength, and the type of virus causing the illness. Children, older adults, and people with weakened immune systems may take longer to improve.
Can a Stomach Bug Last for a Week?
Yes, it’s possible for a stomach bug to last a week, but this is not typical. A few situations can lead to longer-lasting symptoms, including:
- A More Severe Viral Infection: Some viruses take longer to clear, especially in children or individuals with compromised immunity. While norovirus tends to resolve within 1-3 days, other strains can linger.
- Post-Viral Irritation: Even after the virus has left your system, your digestive tract may still be inflamed. This can lead to continued diarrhea, stomach discomfort, or reduced appetite for several days.
- Dehydration and Poor Nutrition: If you haven’t been able to eat or drink normally, your recovery may slow down. Dehydration can worsen nausea and fatigue, making it feel like the illness is dragging on.
- Misdiagnosis of Symptoms: What feels like a stomach bug might not be a simple viral infection. Food poisoning, bacterial infections, and inflammatory conditions can all mimic the symptoms of gastroenteritis but last much longer.
When a Long-Lasting “Stomach Bug” Might Be Something Else
If your stomach bug symptoms have lasted longer than a few days, it’s possible that the issue isn’t a viral infection at all. Many illnesses can feel like a typical stomach virus at first but tend to last longer, cause more intense symptoms, or require specific treatment to improve. When symptoms continue for a week or more, one of the following conditions might be the real cause:
- Bacterial food poisoning can trigger diarrhea, cramping, and fatigue that lasts several days or more
- Bacterial gastroenteritis, which may cause worsening symptoms, persistent fever, or severe stomach pain that doesn’t improve without antibiotics
- Parasitic infections like Giardia, known for causing long-lasting bloating, loose stools, and stomach discomfort
- IBS flare-ups, which can be triggered by a prior infection and lead to ongoing abdominal discomfort, urgency, or gas
If your symptoms aren’t improving or are getting worse, urgent care can help determine the cause and provide the right treatment.
When To Visit Urgent Care
You don’t have to wait an entire week to seek medical care. Visit urgent care if you experience:
- Symptoms lasting more than 3 days with no improvement
- Signs of dehydration (dizziness, dry mouth, dark urine)
- Persistent vomiting
- Blood in stool or vomit
- High fever
- Severe stomach pain
- Inability to keep fluids down
Urgent care providers can evaluate your symptoms, provide medications to control nausea or diarrhea, and test for bacterial infections if necessary.
