Long Covid: breathing difficulties, abdominal pain, fatigue… one in eight patients would have at least one lasting symptom

Among people with Covid 19, one in eight retains one of the characteristic symptoms of long Covid for the long term, shows a large study published on Friday.

These symptoms understand “abdominal pain, breathing difficulties and pain, muscle pain, ageusia or anosmia (loss of taste or smell: editor’s note)tingling, discomfort in the throat, hot or cold flushes, heaviness in the arms or legs and general fatigue”lists this study published in the Lancet.

“In 12.7% of patients, these symptoms can be attributed to Covid-19”three to five months after infection, conclude the authors.

This work, carried out in the Netherlands, is, by its scope and its methodology, an important piece for better understanding the risk of covid longi.e. the persistence of lasting symptoms after infection with coronavirus.

In the current state of knowledge, we know that there are sequelae specific to a coronavirus infection in certain patients and that these are not solely explained by psychosomatic disorders, as certain doctors have previously put forward.

But the frequency of these disorders and, even more so, the physiological mechanisms by which they occur are largely unknown.

If the Lancet study does not answer this second questioning, it makes it possible to better clarify the first element, firstly because it was carried out on a large number of patients: more than 4,000 competent people with Covid.

In these patients, the episode of Covid-19 was proven by a PCR test or a doctor’s diagnosis.

Finally, and this is an important novelty, the responses of these patients were compared to those given by a group of people who did not have Covid.

Because it is possible to feel one of the symptoms reported, without the Covid being the cause. In fact, nearly 9% of people who have not had Covid have one of the symptoms previously described.

Among former Covid patients, the proportion rises to 21.4%. It was by subtraction that the researchers managed to conclude that just over 12% of people struck by Covid developed a sequelae linked to the disease.

However, this study has certain limitations, such as not having measured the frequency of other symptoms associated with long Covid, including in particular a state of depression or mental confusion.
