How Long Does Post Covid Fatigue Last

What About Patients Who Have Suffered From Mild Covid

Fatigue after COVID-19 Infection

Dr Dipu TS reassures that in such cases, fatigue may last for 2-3 weeks from the time they tested positive for Covid-19. In patients with severe infection, it may last for certain weeks to months. Age , sex , and presence of comorbidities may be considered as some of the reasons for the persistence of fatigue in individuals.

Autonomic Nervous System Disruption

A third possible explanation of fatigue in long haulers involves disruption of the autonomic nervous system .

The ANS is part of the nervous system and controls our bodys internal organs without us even noticing. It influences muscles and organs throughout the body and controls a range of functions such as heart rate, breathing, and digestion.

The ANS has multiple parts. Two of the most important are the sympathetic nervous system and the parasympathetic nervous system .

When our brain suspects theres a threat, it activates the SNS, which in turn starts pumping blood to muscles and increases breathing rate. The aim is to make you ready to fight for your life, and this is why its called the fight or flight mode. When the threat is gone, the PNS kicks in and calms everything down. This is often called the rest and digest mode.

In healthy individuals, the SNS and PNS are in a constant state of flux, with each system making small adjustments throughout the day. In long COVID patients, however, there is evidence to suggest the sympathetic nervous system becomes dominant. Not surprisingly, staying in this constant mode of physically heightened alert resultsin physical, mental, and emotional exhaustion.

You can read more about how this works and the symptoms it causes in our article about autonomic nervous system dysfunction in post-concussion patients.

Is This Like Chronic Fatigue Syndrome

We knew about chronic fatigue syndrome, otherwise known as myalgic encephalomyelitis, well before COVID.

This often develops after a viral infection . So, understandably, there has been concern around the coronavirus potentially triggering chronic fatigue syndrome.

There are striking similarities between chronic fatigue syndrome and long COVID. Both involve debilitating fatigue, brain fog and/or muscle aches.

But at this stage, researchers are still untangling any link between post-COVID fatigue, long COVID and chronic fatigue syndrome.

For now, we know many people will have post-COVID fatigue but thankfully do not go on to develop long COVID or chronic fatigue syndrome.

What Does Post Covid

Have you been waking up every morning post-Covid with an ache that makes you squeal in pain? You are NOT alone. Plus, as the day progresses, you experience a slump in your energy levels. And before you know it, you are drowning in drowsiness, even after having multiple cups of coffee. Welcome to a world where this has become oh-so-normal.

Lets get to the reasons now. Dr Dipu TS explains why this happens.

It could be due to a continuing response to the coronavirus, even though the infection has gotten better. It could also be due to the effect of a serious illness. Fatigue caused by pneumonia can take up to 6 months to resolve. In some people, there will be other reasons that make it last a long time. Low levels of physical activity, a disturbed daily routine, poor sleep patterns, demanding work, anxiety, and stress can all make fatigue worse.

How Does A Booster Vaccine Impact The Length Of A Sickness


Staying up-to-date on your booster vaccines, which are additional shots given to prime your immune system after your first two mRNA-based vaccinations, can shorten the length of your sickness. In line with what vaccine experts have previously established, Dr. Wright explains that vaccine antibodies decrease naturally over time, and lower amounts of this immunity often result in a longer breakthrough sickness. Getting a third booster shot when it’s available to you enables your immune system to better respond to a breakthrough infection in the long run.

If you’re currently in recovery from a breakthrough COVID-19 case, you may be wondering if it’s too late to get a third or fourth vaccine dose. Usually, healthcare providers ask that sick individuals wait until they’ve recovered and no longer must quarantine to think about signing up for an additional COVID-19 vaccine but CDC officials note that some may choose to wait an additional 12 weeks from the end of their recovery. “Reinfection is less likely in the weeks to months after infection,” the CDC guidance page reads. “Certain factors, such as personal risk of severe disease, local COVID-19 community level, and the dominant COVID-19 variant, could be reasons to get a vaccine sooner rather than later.”

What Cdc Is Doing

CDC continues to work to identify how common post-COVID conditions are, who is most likely to get them, and why some symptoms eventually improve for some people and may last longer for other people. Rapid and multi-year studies are underway to further investigate post-COVID conditions in more detail. These studies will help us better understand post-COVID conditions and how to treat patients with these longer-term effects.

How To Recover From Post

For most long haulers, fatigue is one of their many symptoms. Long COVID can affect every organ in the body, causing difficulties from shortness of breath and trouble sleeping to erectile dysfunction and heart palpitations.

Instead of treating each symptom separately, we approach long COVID as a whole.

Soon after long COVID appeared, we realized this condition impacts the brain in a similar way to post-concussion syndrome , the primary condition we treat at our clinic. PCS occurs when concussion symptoms fail to resolve months after a head injury. Some of our patients have spent decades suffering from headaches, dizziness, brain fog, and more before finding our clinic.

Note: While concussions are the most common cause of post-concussion syndrome, blunt trauma is not the only way to injure your brain. Weve treated patients who injured their brains via carbon monoxide poisoning, encephalitis from an infection, transient ischemic stroke, and more. In this sense, COVID-19 is no different in that it causes brain dysfunction.

After confirming our suspicions of the similarity between long COVID and post-concussion syndrome via neuroimaging, we adapted our treatment protocols for COVID long haulers.

We use these results to design a customized treatment plan combining a series of cardio exercises and other therapies, including cognitive, sensorimotor, neuromuscular, and vision therapies, to name just a few.

We follow a prepare/activate/rest pattern:

Fatigue Or Tiredness Whats The Difference

The term fatigue can mean different things to different people. Some people mean their muscles are easily weakened. Walking to the mailbox feels like they have run a marathon. Others describe a generalised exhaustion, whether they are moving or not. People can experience physical, mental or emotional fatigue, or any combination of these.

The difference between tiredness and fatigue is this: tiredness can get better with enough rest, while fatigue persists even if someone is sleeping and resting more than ever.

Impaired Quality Of Life Health System Function

‘I was so fatigued’: Boise man describes COVID-19 recovery after experiencing mild symptoms

The authors noted that the rates of persistent fatigue in the study were much higher than those reported in a 2006 study of patients after recovery from Epstein-Barr virus, Q fever, or Ross River virus, but that a 2009 study reported that 40% of patients had fatigue 1 year after recovery from infection with the coronavirus that causes severe acute respiratory syndrome .

“A lengthy post-infection fatigue burden will impair quality of life and will have significant impact on individuals, employers and healthcare systems,” the authors said. “This study highlights the importance of assessing those recovering from COVID-19 for symptoms of severe fatigue, irrespective of severity of initial illness, and may identify a group worthy of further study and early intervention.”

Fatigue After Covid Is Way More Than Just Feeling Tired Five Tips On What To Do About It

by Natasha Yates, The Conversation

People are often surprised by how fatigued they are during a COVID infection.

Fatigue is more than being worn out or sleepy. It’s an excessive tiredness that persists despite resting or good sleep. It’s likely a result of our body’s strong immune response to the virus.

But in some people the fatigue drags on even when the infection is gone. This can be debilitating and frustrating. Simply resting more makes no difference.

Here’s what we know about post-COVID fatigue, and what can help.

Fatigue or tiredness? What’s the difference?

The term fatigue can mean different things to different people. Some people mean their muscles are easily weakened. Walking to the mailbox feels like they have run a marathon. Others describe a generalized exhaustion, whether they are moving or not. People can experience physical, mental or emotional fatigue, or any combination of these.

The difference between tiredness and fatigue is this: tiredness can get better with enough rest, while fatigue persists even if someone is sleeping and resting more than ever.

How big a problem is this?

Because there is no agreed definition of post-COVID fatigue, it is impossible to give exact numbers of how many people experience it.

Jeez, the post-COVID brain fog and fatigue are so real. After missing 7 days of work and trying to now catch up, I physically feel like I’ve just run a marathon, and I keep forgetting what it was that I was doing.

How Common Is Fatigue In Covid

Feeling fatigued is a very common symptom of COVID-19 for all age groups. On average, around eight in ten adults who are ill with COVID-19 will experience fatigue. Itâs slightly less common in children, affecting around half of those with COVID-19.

While 82% of app contributors who tested positive for coronavirus reported fatigue, just this symptom alone is not a sure sign of having COVID-19. Only 13% of people who were ill with COVID-19 experienced fatigue as their only symptom.

What Can I Do To Manage Covid

People always want to know how long postCOVID-19 fatigue lasts. The answer is, doctors dont currently know. It can be weeks or even months.

The best thing you can do to manage COVID-19 fatigue is to practice self-care and be kind to yourself.

Here are some tips from the United Kingdoms National Health Service on how to take care of yourself while you heal.

How Is It Diagnosed

Treating long COVID: Clinician experience with post

Post-viral fatigue can be improved through the practices suggested above and a sound balance of rest, activity and pleasure. It can, however, take many months to recover fully. Following a viral infection, you may seem slow to recover within what you would consider your normal time frame. If this is the case and your fatigue symptoms are persisting and are interfering with your capacity to carry out normal day-to-day activities, then we recommend that you visit your GP for further tests in the context of a full clinical picture.

Depending on the outcome of this you may be referred to a specialist fatigue service if they are available. We are also very happy to talk to you about whether one of our rehabilitation programmes could support you.

Many Infections Mean Many Long Covid Cases

David Putrino is an Australian neuroscientist who leads several long COVID rehabilitation clinics at Mount Sinai Health System in New York.

He’s a lot less optimistic about what Australia faces as the Omicron wave subsides.

His clinics have treated hundreds of patients with mild COVID-19 who later developed long COVID.

“What we’ve seen over and over again is that the severity of the disease in the acute phase does not predict who’s going to go on to get quite severe long COVID,” he said.

And even if vaccination and a less severe variant do reduce the proportion of people who get long COVID, the sheer number of infections Australia is facing now will mean a lot of people will get long COVID, Professor Putrino added.

University of Melbourne public health expert Nancy Baxter agreed.

“Hopefully, with a milder disease, less people will have long COVID,” Professor Baxter said.

“But we know with previous variants that even if you had mild disease, there was still some risk of developing it.

” if you’re infecting 10 times or 100 times more people, that may mean we see a lot more long COVID than we did with other variants.”

What Are The Symptoms Of Post

The main symptom is a significant lack of energy that is not improved through sleep. It is often accompanied by other symptoms which can vary and may include headaches, and heavy, aching muscles, for example. These symptoms fluctuate so that some days a person can feel better and manage to engage in activities, and then a subsequent day be incapacitated with debilitating symptoms again.

Will Omicron Leave A Legacy

Long COVID has been defined by the United States’ Centers for Disease Control and Prevention as symptoms lasting at least four weeks after being infected with the virus that causes COVID-19.

Estimates vary, but research that has been done on earlier variants prior to the arrival of Omicron suggests between 10 and 30 per cent of people who get COVID-19 may have symptoms that persist beyond four weeks.

If that holds true with the Omicron variant, Australia could see hundreds of thousands of people experiencing persistent symptoms and long COVID.

But Professor Macartney said she hoped it wouldn’t be that bad.

“You’re more likely to get persistent symptoms if you’ve had a severe illness,” she said.

Vaccinations reduce the severity of COVID-19, meaning Australia’s population which had a double-dose vaccination rate of 78 per cent this week could be somewhat protected from long COVID, according to Professor Macartney.

And the Omicron variant’s tendency to produce less severe disease should also help, she said.

“We hope to see fewer cases of long COVID and particularly the really significant long COVID, where there are substantial symptoms lasting many, many months.”

Histamine And Mitochondrial Dysfunction Could Also Be To Blame

WHOs Science in 5 on COVID-19: Post COVID-19 condition – 30 July 2021

Long Covid and ME could also be down to something known as mass cell activation syndrome, where infections can destabilise the mass cells where histamine is produced. This could explain the allergy-type symptoms like rashes and hives experienced by some long Covid patients.

There is also evidence of mitochondrial dysfunction in people with CFS.

Mitochondria are sort of the Duracell batteries within muscle cells that are where energy is produced, says Shepherd.

Weve now got quite a lot of evidence showing that theres a defect in metabolic energy production at a cellular level in people with ME, so there is a biochemical explanation for the fatigue that is going on.

Whether theres mitochondrial dysfunction going on in long Covid I dont know, because no ones really had the time of the opportunity to study it, but its certainly another possibility for therapeutic intervention.

I propose that a dysfunctional, overloaded hypothalamic PVN, can act as an epicenter for localized microglia induced activation. Pro-inflammatory cytokines and neurotoxic molecules would be released in response by microglial and astrocyte cells , causing neuroinflammation to spread throughout the hypothalamus and into its proximal, closely connected, limbic system. A dysfunctional hypothalamus and limbic system could then explain the majority of the wide range of ME/CFS-like symptoms being reported in PCFS , and as has been explained in more detail previously for ME/CFS .

What Can I Do To Manage Covid Fatigue

Fatigue can drain your energy and keep you from doing day-to-day things when youre down with a viral sickness like COVID-19 or long-haul COVID-19.

To manage your health and ease fatigue symptoms while youre sick or post-COVID, you should:

  • Accept that fatigue is a real side effect of having COVID-19.
  • Make sure to get a good nights sleep. This can help your body preserve energy.
  • Try relaxation techniques like mindful meditation, aromatherapy, yoga, and tai chi. These can help to reduce stress and fatigue symptoms.
  • Plan ahead on what you can get done with limited energy.
  • Prioritize the tasks that are important. This will help you spend energy on only those things that need to be done.
  • Delegate certain tasks to others who can complete them for you. This can include activities like grocery shopping or cooking.
  • Try to stay active. A viral infection can knock your energy out, but moving and light exercise can energize you.
  • Keep a diary on all things that either trigger your fatigue or make it worse. This will help you steer clear of energy-draining activities.
  • Eat foods that give your body energy.
  • Stay hydrated.

How Long Do Body Aches And Muscle Pains Last From Covid

Body aches or muscle pains may be an early symptom of COVID-19, often appearing at the very start of the illness and lasting for an average of 2-3 days. Unfortunately, COVID-19 body aches can sometimes last much longer and are commonly reported in people with long COVID-19 or post COVID-19 syndrome.

Dr. Fauci Warns These COVID Symptoms Can Last for Months

According to data gathered in the ZOE COVID Study, fatigue commonly occurs within the first week of the illness and lasts for an average of five to eight days, though some people may have COVID-related fatigue for two weeks or longer.

The severity of fatigue is often correlated to the severity of illness. Typically, the worse the illness, the longer the fatigue is likely to last. For people who had to be admitted to intensive care for COVID-19, it might be a few months before they get back to where they were before they got sick, says McClelland.

For people who feel bad but are able to ride out COVID-19 at home, it might take just a week or two for the fatigue to abate, says McClelland.
