COVID 19 is primarily a disease of the lungs but it can affect other organs as well. After recovery from the acute illness and “testing negative”, unfortunately some people continue to have significant symptoms. This group of people are called COVID “long haulers”. A recent study published in the journal Diabetes, Obesity and Metabolism found that obesity is a significant risk factor for becoming a COVID long hauler after recovery from the acute illness.

According to a recently published article in the British Medical Journal, a spontaneous pneumothorax (punctured lung) is very common in COVID affected  lungs. The underlying mechanisms are thought to be due to the fibrosis and scarring caused by COVID 19 which weakens the lung surface and the higher use of oxygen often under pressure during the acute phase of the illness.

ARDS is a common occurrence in patients with severe COVID 19 pneumonia and hypoxaemia. All patients with ARDS from COVID 19 pneumonia do not have the same prognosis according to recent research published by the Lancet group of journals.
