Lingering Aftereffects
As we approach the one-year mark of the COVID-19 pandemic, there is a silver lining: the vast majority of even the most vulnerable groups recover from the initial illness. However, this optimistic scenario is accompanied by a troubling reality, particularly highlighted by the emergence of what is frequently referred to as “long-haulers syndrome.”
This post-viral condition persists long after the initial infection subsides, presenting a range of symptoms from joint discomfort to chronic fatigue. Although comprehensive long-term studies are still emerging, we are starting to gain insights into how the SARS-CoV-2 virus affects the body and strategies to facilitate recovery.
The Impact of SARS-CoV-2 on the Body
What stands out about long-haulers syndrome is its diverse presentations, likely due to the virus’s capacity to attach to any cells containing angiotensin-converting enzyme 2 (ACE-2), which are present in the nose, lungs, kidneys, liver, blood vessels, immune system, brain, nerves, and muscles.
During the initial infection, this can lead to a “cytokine storm,” causing issues such as excessive blood clotting, increased vascular permeability, swelling, widespread inflammation, and subsequent damage to multiple organs.
In theory, the protracted effects of inflammation, tissue damage, and lingering viral remnants could show up as a variety of symptoms that linger for considerable periods.
“I’m not back to normal yet,” shares Erica B., a 55-year-old college English professor from BC, who is nearing the halfway point of her sixth month battling lingering COVID-19 symptoms. “I still deal with unusual fatigue and occasional lung issues.”
Prior to her COVID-19 infection, Erica enjoyed walking her dog, managing household tasks, and engaging in strength training and rowing. “My life came to a standstill for over four months,” she recalls. Each time she attempted to exercise or run errands after the acute phase, she found herself relapsing with lung issues, severe fatigue, and malaise after exertion.
“The fatigue resembled a mix of jet lag and low blood sugar,” Erica shares. “Like many fellow long-haulers, I experienced a severe skin rash that lingered for weeks.”
Erica’s diminished lung capacity is common among individuals who have faced severe viral pneumonia. While it’s anticipated that most COVID-19 survivors will likely return to their normal lives, a notable number may exhibit anomalies in lung function assessments. By the five-and-a-half-month mark, Erica felt energized enough to resume physical activities, although she now finds herself working to regain her previous level of fitness.
Assessing Risk Levels
Although anyone can contract the SARS-CoV-2 virus and develop COVID-19, data consistently suggests that certain demographics, including the elderly, ethnic minorities, and individuals with pre-existing health issues, face higher risks of severe illness and death from COVID-19.
Type 2 diabetes and obesity frequently contribute to the health disparities observed in these populations. The encouraging aspect is that such conditions can often be effectively managed through lifestyle modifications. Addressing obesity is particularly vital, as research indicates that vaccines may be less effective in individuals who are obese.
It is widely recognized that diets typical of Western lifestyles play a role in the rising rates of type 2 diabetes and obesity.
Additionally, Western dietary patterns can hinder T-cell and B-cell functions—both essential for the body’s defense against viral infections. Identified T- and B-cell counts are notably low in those afflicted with COVID-19.
Future Considerations
The long-term impact of COVID-19-associated myocarditis (inflammation of the heart) on cardiovascular health remains to be fully determined. Similarly, the lingering effects of intracranial hemorrhage and stroke are uncertain, but they may correlate with nervous system damage.
There is a possibility that some COVID-19 patients might face increased susceptibility to neurological disorders in the future, given historical instances of dementia in older individuals following viral infections, including respiratory viruses like influenza. The presence of SARS-CoV-2 in neurons could lead to neurological symptoms and nerve degeneration even months or years after the initial infection without acute toxicity.
Furthermore, COVID-19 may raise the likelihood of anxiety, depression, post-traumatic stress disorder, insomnia, and psychosis later on. Regular mental health evaluations and seeking appropriate support will be particularly crucial for both those experiencing long-haul COVID-19 and those who have already overcome the illness.
Restoring Health in the Long Run
While adequate research on the direct correlation between nutritional therapy and COVID-19 outcomes is still lacking, it is reasonable to assume that consuming a varied diet rich in vegetables, lean proteins, and healthy fats—rather than sugary, carbohydrate-laden, and processed foods—could prove advantageous. Studies in the field of psychoneuroimmunology indicate that a healthy lifestyle, which includes consistent physical activity, balanced nutrition, quality rest, and strong social connections, positively influences the immune system.
Most importantly, be kind to yourself. Take it slow as you ease back into work and vigorous exercise, and avoid adhering to strict deadlines for your recovery. Allow yourself to rest, seek professional assistance for any overwhelming emotions, and redefine productivity until you feel more like your former self.
