The world has come to recognize the devastating impact of the COVID-19 pandemic, but what many are still grappling to understand is the phenomenon known as “long COVID” or “post-acute sequelae of SARS-CoV-2 infection (PASC)”. This condition encompasses a range of symptoms that continue for weeks or months after the acute phase of a COVID-19 infection has resolved.

Inflammation: The Silent Foe

One of the most pressing concerns with long COVID is the heightened state of inflammation. While inflammation is a natural response of our immune system to threats, chronic inflammation can lead to a host of health issues. Studies have found elevated levels of certain inflammatory markers in long COVID patients, suggesting that a sustained inflammatory response could be behind some of the persistent symptoms.

Symptoms of Long COVID

While long COVID can affect different people in various ways, some of the more commonly reported symptoms include:

Fatigue: Many describe a profound level of exhaustion that doesn’t improve with rest.

Cognitive Impairment: Often referred to as “brain fog,” patients report issues with memory, concentration, and other cognitive functions.

Breathing Difficulties: Even after recovering from the acute phase, some individuals still face challenges with breathing, often feeling short of breath.

Joint Pain: Persistent pain in joints without visible swelling or redness is another hallmark symptom.

Cardiac Symptoms: These can range from palpitations to chest pain and even long-term heart inflammation.

Depression and Anxiety: The mental health toll of long COVID is significant, with many patients reporting feelings of depression, anxiety, and other mood disorders.

Sleep Disorders: Difficulty sleeping or altered sleep patterns have been noted among many long COVID sufferers.

What Triggers Long COVID?

The exact cause of long COVID remains elusive, but several theories have been posited. Some believe that the virus may linger in some small pockets of the body, causing ongoing symptoms. Others hypothesize that the immune system, having been triggered by the virus, continues to remain overactive, leading to symptoms like fatigue and brain fog. The prolonged inflammatory response, too, could be a byproduct of this immune dysregulation.

While there are currently no treatments for long COVID, there is a promising new clinical trial underway that places nutrition at the heart of long COVID research. From the recent press release about this trial: “Is Nutrition the Answer to Long-COVID? A Clinical Trial will Explore the Impacts of the Medical Food, KetoCitra® together with a Low-Carbohydrate Diet.”

Managing Long COVID

Management of long COVID is still evolving, as researchers and healthcare professionals learn more about the condition. Currently, treatment is symptomatic, aimed at alleviating the discomforts faced by the patients. Rehabilitation, physical therapy, and counseling have been beneficial for many. Anti-inflammatory medications are also being explored as potential treatments.

Long COVID serves as a reminder that the impact of the pandemic goes beyond the immediate crisis. As researchers continue to investigate, understanding and addressing the needs of those suffering from this condition is paramount. It’s essential to acknowledge the challenges they face and ensure they receive the necessary support and care.
