When you come down with the flu, you probably expect symptoms such as fever, body aches, chills, coughing, and fatigue. But what happens when the food you eat suddenly becomes bland or you can barely smell anything? Changes in your senses can be surprising, especially when they appear alongside other flu symptoms. So, can the flu cause loss of taste or smell? Yes, influenza can sometimes affect your ability to taste and smell, most commonly when nasal congestion and inflammation interfere with your sense of smell. However, a sudden or complete loss of these senses can also be associated with other respiratory infections, like COVID-19. Understanding why these changes happen, how long they may last and which symptoms deserve medical attention can also help you determine what to do next.

Why Can the Flu Affect Your Sense of Taste or Smell?
Influenza can cause inflammation and congestion in your nose and upper respiratory tract. When your nasal passages become swollen, odor molecules may have difficulty reaching the receptors responsible for detecting smells. Because smell plays a major role in how you experience flavor, congestion can make food seem bland even when your basic sense of taste remains intact. Common symptoms include:
- Reduced ability to smell food, perfumes, or other scents
- Food tasting bland or less flavorful
- Nasal congestion or a runny nose
- Difficulty distinguishing different flavors
When congestion improves, your sense of smell and taste of food will often improve as well. However, a complete loss of smell is less characteristic of the flu than congestion-related changes. If you suddenly lose your sense of smell or taste, do not automatically assume influenza is the case.
Is Loss of Taste or Smell a Sign of the Flu or COVID-19?
The flu, COVID-19, and the common cold share several symptoms, including coughing, congestion, sore throat, and fatigue. All three can affect how well you can smell and taste. There are some differences to consider, including:
- Flu: Changes in taste and smell may occur alongside nasal congestion, fever, body aches, and fatigue
- COVID-19: Loss of smell or taste can occur even without significant congestion, although it is less common with some newer variants
- Common Cold: A stuffy nose can temporarily reduce your ability to smell, making food seem less flavorful
Because these symptoms overlap, you cannot reliably identify the infection based on taste or smell changes alone. Testing may help determine whether you have influenza or COVID-19, especially if you’re at higher risk for complications.
How Long Does Loss of Taste or Smell Last With the Flu?
If your symptoms are caused by congestion from the flu, your senses will often begin returning as the swelling and mucus in your nasal passages improve. Flu symptoms generally improve over several days, although coughing and fatigue can last longer. Changes in taste and smell may resolve within a similar period if congestion is the primary cause. Recovery varies, however, and persistent inflammation or another underlying condition can cause these symptoms to last longer. To help manage congestion while recovering, be sure to drink plenty of fluids, get adequate rest, and consider using saline nasal sprays or rinses to clear mucus.
When Should You Visit Urgent Care?
Temporary changes in taste and smell during a respiratory infection are not always a cause for concern. However, certain symptoms may warrant medical evaluation. Consider visiting an urgent care center if you experience:
- Sudden or unexplained loss of taste or smell
- A fever that returns after you initially feel better
- Worsening sinus pressure or facial pain
- Symptoms that persist or worsen instead of improving
- Flu-like symptoms and uncertainty about whether you have the flu or COVID-19
A healthcare professional can evaluate your symptoms and determine whether testing or additional treatment is appropriate. If you’re at a higher risk for flu complications, seek medical advice promptly because antiviral medications work best when started early, ideally within the first 48 hours of symptoms.
