Unraveling the Mystery of Lingering Symptoms After COVID: What You Need to Know
The COVID-19 virus has had a profound impact on global health, and new information about its effects continues to emerge. While many people recover from COVID-19 with little trouble, others experience ongoing symptoms. Even people who had a mild case of the virus can experience symptoms that persist long after their initial infection has resolved. This is known as post-acute sequelae of SARS-CoV-2 infection, or PASC.
What are the symptoms of PASC?
The symptoms experienced by people with PASC vary widely, but they tend to involve multiple body systems. Common symptoms include shortness of breath, fatigue, brain fog, muscle and joint pain, and sleep disturbances. Other symptoms can include headaches, dizziness, chest pain, heart palpitations, and gastrointestinal issues. Some people also experience mental health symptoms such as depression, anxiety, or post-traumatic stress disorder.
What Causes PASC?
It’s not yet clear what causes PASC, but researchers are investigating several possible mechanisms. The virus itself may have long-lasting effects on various systems in the body, including the immune system, the nervous system, and the cardiovascular system. Some theories suggest that PASC could be caused by an overactive immune response, or by small amounts of the virus persisting in the body and triggering ongoing inflammation. Other researchers are exploring the possibility that PASC is related to changes in the microbiome, or to long-term damage to the lungs or other organs.
How is PASC Diagnosed and Treated?
Diagnosing PASC can be challenging because there is no single set of diagnostic criteria. Generally, people who continue to experience symptoms for several weeks or months after their initial infection may be diagnosed with PASC. Doctors may use a variety of tests and imaging studies to evaluate the function of different organs and systems in the body.
Treating PASC is also difficult because there is no established cure or treatment protocol. Doctors may prescribe medications to manage specific symptoms, such as pain relievers or sleep aids. Physical therapy and other forms of rehabilitation can also be helpful for some people. However, there is still much to be learned about how to effectively manage the complex and varied symptoms of PASC.
Conclusion: What You Need to Know About PASC
PASC is a complex and poorly understood condition that can cause ongoing symptoms for people who have recovered from COVID-19. Recognizing the symptoms of PASC and seeking appropriate medical care is important for managing this condition. Researchers are continuing to investigate the underlying causes of PASC and developing new treatments, but there is still much to learn about this condition. With time and continued research, we hope to gain a better understanding of PASC and how to effectively treat it.
