According to South African scientists, persistent blood clotting may be the cause
Researchers at Stellenbosch University in South Africa said they have evidence that significant and persistent microclots can explain the symptoms of coronavirus patients with persistent symptoms.
Physiology professor Resia Pretorius revealed the results of her research on the identification and causes of long-term Covid in an article published in the Guardian on Wednesday.
Pretorius attributes this condition and its symptoms to a phenomenon called microclotting. “A recent study in my laboratory showed that both acute Covid-19 and long-term Covid patients have obvious microclot formation in the blood.” The scientist wrote.
She pointed out that humans are usually able to break down clots through a process called fibrinolysis. However, her research data shows that people with long-term new coronary pneumonia cannot overcome micro-clotting.
“Persistent micro-clots and over-activated platelets (also involved in coagulation) persist coagulation and vascular disease, causing cells to not get enough oxygen in the tissues to maintain body functions (called cellular hypoxia),” She wrote.
She concluded that hypoxia may be the cause of the debilitating symptoms reported by long-term Covid patients.
This reinforces the early observations that acute Covid-19 affects not only the respiratory system but also the cardiovascular system.
Pretorius pointed out that people who have suffered from Covid for a long time cannot easily diagnose their condition because proper pathology tests are not easily available.
She called “urgent“To study the condition to help diagnose and formulate treatment plans, especially considering that hypoxia can increase the risk of stroke and heart attack.
It is believed that 100 million people worldwide are suffering from the ongoing symptomatic coronavirus. The patient reported many symptoms, including extreme fatigue, brain fog, muscle weakness and difficulty sleeping, as well as persistent breathing problems associated with Covid-19.
Others have noticed the development of anxiety and depression.
