Post COVID 19

While many individuals recover fully from COVID-19, some continue to experience symptoms weeks or months after their initial infection. This condition is commonly referred to as Post-COVID-19 condition, also known as Long COVID. It can affect people of all ages and may occur even after a mild or asymptomatic COVID-19 illness.

Post-COVID-19 condition is defined as a range of new, returning, or ongoing health problems that persist after the acute phase of COVID-19. Symptoms may last for months, fluctuate over time, or interfere with daily activities and quality of life. There is no single test to diagnose Long COVID; diagnosis is based on medical history, symptoms, and clinical evaluation.

Long COVID can involve multiple organ systems. Common symptoms include:

• Shortness of breath or difficulty breathing
• Persistent cough or chest tightness
• Fatigue or reduced exercise tolerance
• Brain fog or difficulty concentrating
• Muscle or joint pain
• Headaches
• Sleep disruption
• Mood changes, including anxiety or depression
• Palpitations or dizziness
   

Respiratory symptoms are among the most frequently reported, particularly in individuals who experienced lung involvement during their COVID-19 infection.

COVID-19 can cause inflammation in the lungs that may take time to fully resolve. Some patients experience ongoing shortness of breath, coughing, or decreased stamina long after the infection has cleared. In certain cases, lung function testing or imaging may be needed to evaluate persistent symptoms and guide treatment.

Fatigue is one of the most common and disabling symptoms of Long COVID. Many patients report feeling exhausted after minimal activity or experiencing unrefreshing sleep. These symptoms often overlap with respiratory limitations, autonomic dysfunction, and changes in daily routines following illness.

Addressing sleep quality, breathing patterns, and overall pulmonary health can play an important role in improving energy levels and functional recovery.
