Is Fatigue a Sign of COVID-19?

It's actually a pretty common symptom of any viral infection.

Occasionally feeling run-down is a part of life. However, fatigue is a different story: It occurs when a person is not very energized, tired, or weary, according to MedlinePlus. Fatigue even involves having a lack of motivation in some cases. So, how can you tell if your tiredness is due to COVID-19 or something else entirely?

How Common Is Fatigue With COVID-19?

Though the Centers for Disease Control and Prevention (CDC) has listed fatigue as an official symptom of COVID-19 as of March 2022, having fatigue doesn't automatically mean that you have the virus, Amesh Adalja, MD, senior scholar at the Johns Hopkins Center for Health Security, told Health. "It's kind of a nondescript symptom," said Dr. Adalja.

Still, feeling wiped out is common with most viral illnesses. "It has to do with substances called cytokines that the immune system produces when under attack," Richard Watkins, MD, an infectious disease physician in Akron, Ohio, and a professor of medicine at the Northeast Ohio Medical University, told Health. Those cytokines signal to your body that it's time to go to work and fight off an infection, but the aftermath can make you feel tired. After all, your body is focusing its energy on fighting off an invader, even if you can't see it.

Experts have found also that some individuals deal with long-term effects—known as post-COVID conditions—as a result of having had COVID-19. Among those symptoms are issues like difficulty breathing, sleep problems, and fatigue that interrupts everyday life. In an August 2021 study published in Scientific Reports, researchers conducted a literature review focused on the long-term effects of COVID-19. Across the 15 studies that met their inclusion criteria, 80% of the COVID-19 patients developed at least one long-term symptom—fatigue was one of the most reported symptoms among 58% of individuals.

How Can You Know if Your Fatigue Is a Symptom of COVID-19?

This can be a little hard to determine at times. In general, Dr. Adalja said that you should have other symptoms as well. "Usually you'll have some symptoms, like muscle aches, pains, or a sore throat, even if it's minor," added Dr. Adalja. "It's usually not just fatigue in and of itself."

That doesn't mean you can't have COVID-19 and only experience fatigue as a symptom—it's just not common.

To try to figure out what's going on, Dr. Adalja recommended looking at your fatigue as part of the bigger picture. For example, it might be due to the nature of your work environment, home life, or a combination of both if you work from home. "You have to think about why you're fatigued," said Dr. Adalja. "Is it because you ran a marathon or were up late, studying for a test? Try to see if you have an easy explanation."

And, of course, calling your doctor is always an option. They may want to test you for COVID-19 or do a physical exam, given that a wide range of health issues and lifestyle factors can cause fatigue.

How Do You Treat Fatigue From COVID-19?

There are ways to manage fatigue during or after the time you have had COVID-19. Researchers from an April 2022 study published in the Indian Journal of Tuberculosis provided the following suggestions to overcome fatigue after a COVID-19 infection:

  • Resting and allowing time for recovery
  • Being active but keeping activity low
  • Having a balanced diet
  • Pausing studies or work responsibilities
  • Building time to have fun on a daily basis

The CDC has also offered recommendations for preventing COVID-19 infection, such as getting vaccinated and monitoring your health for signs and symptoms of the disease. Of note, as of January 2022, the CDC has also noted reports of side effects—including tiredness and fatigue—after people have received doses of the COVID-19 vaccine. However, in general, the majority of side effects have reportedly been mild or moderate.

Overall, if concerns about chronic fatigue remain, it's always a good idea to talk with your doctor to determine what will work for you on an individual basis.
