Long COVID
Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), refers to a range of symptoms and health issues that persist for weeks or months after the initial recovery from a COVID-19 infection. While most individuals recover fully from COVID-19 within a few weeks, some experience lingering effects that can significantly impact their quality of life.

Palpitations: Irregular heartbeats or a racing heart.

Mental Health Issues: Anxiety, depression, or other mental health challenges.

Symptoms
The exact cause of Long COVID is not fully understood, but several theories suggest:
Immune Response: An overactive or prolonged immune response that continues even after the virus is cleared.
Residual Viral Fragments: Some studies indicate that remnants of the virus may linger in the body, triggering ongoing symptoms.
Organ Damage: Acute COVID-19 may cause damage to the lungs, heart, kidneys, or other organs, leading to lasting health issues.
Microvascular Damage: Damage to small blood vessels may affect blood flow and oxygen delivery to various organs.
Inflammation: Persistent inflammation in various parts of the body may contribute to symptoms.
