Norovirus is a highly contagious virus that causes acute gastroenteritis, commonly known as the stomach flu. It spreads quickly through contaminated food, water, and surfaces, leading to rapid outbreaks in crowded environments. While symptoms such as vomiting, diarrhea, stomach cramps, and nausea are well-known, many people wonder whether norovirus can also cause dizziness. The short answer is yes– dizziness can be a symptom of norovirus, primarily due to dehydration and other physiological responses to the illness. Keep reading to learn more!

Why Does Norovirus Cause Dizziness?
Dehydration
One of the main reasons norovirus can lead to dizziness is dehydration. The virus causes excessive vomiting and diarrhea, leading to significant fluid loss. Dehydration reduces blood volume, which can lower blood pressure and decrease blood flow to the brain, resulting in dizziness or lightheadedness. Signs of dehydration include:
- Dry mouth and throat
- Reduced urine output or dark-colored urine
- Fatigue
- Weakness
- Increased heart rate
Severe dehydration can be dangerous, especially for young children, older adults, and individuals with weakened immune systems. It is crucial to replenish lost fluids with water, oral rehydration solutions, or electrolyte drinks.
Low Blood Sugar
Another possible cause of dizziness during a norovirus infection is low blood sugar. When you’re sick, you may not feel like eating, leading to a drop in blood sugar levels. Since glucose is the brain’s primary energy source, a lack of it can result in dizziness, weakness, and even fainting. If you’re experiencing dizziness along with norovirus symptoms, try sipping on clear fluids that contain sugar to maintain blood sugar levels.
Electrolyte Imbalance
Vomiting and diarrhea not only deplete fluids but also electrolytes like sodium, potassium, and magnesium, which are essential for nerve and muscle function. An electrolyte imbalance can lead to dizziness, muscle weakness, and irregular heartbeats. To restore electrolyte balance, try drinking electrolyte-replenishing drinks, broths or soups, or eating bananas which are rich in potassium.
Vestibular System Disruption
Some individuals experience dizziness due to a disturbance in the inner ear, which controls balance. A norovirus infection can cause inflammation or fluid in the inner ear, leading to dizziness, vertigo, or difficulty maintaining balance. While this is less common, it can occur in people who are particularly sensitive to fluid shifts in the body.
When To Seek Medical Attention
While norovirus is typically self-limiting and resolves within 1 to 3 days, dizziness can be a warning sign of severe dehydration or other complications. Seek medical attention if you experience:
- Severe or persistent dizziness
- Inability to keep fluids down
- Signs of severe dehydration
- Fainting or feeling faint when standing
- Bloody diarrhea or high fever
