Five years into the pandemic, scientists are unraveling the mysteries of Covid-19’s lasting health effects. Research has uncovered a range of long-term consequences, from inflammation-induced damage to brain fog and cardiovascular problems.
The virus is believed to cause inflammation that can harm various parts of the body, including the gut, heart, and blood vessels. This inflammation can lead to conditions such as anxiety or depression, exacerbate existing mental health issues, and even increase the risk of heart attacks, strokes, and irregular heartbeats.
Studies have also shown that Covid-19 can disrupt the balance of beneficial and harmful microbes in the gut, leading to food intolerances and other digestive problems. The virus may also damage the blood-brain barrier, which can result in cognitive symptoms such as memory lapses and difficulty concentrating.
In addition, people with long Covid often experience circulatory problems, including reduced blood flow and impaired oxygen delivery to muscles. This can lead to fatigue, shortness of breath, and a feeling of being unwell after exercise.
The exact mechanisms behind these long-term effects are still not fully understood, but researchers believe that persistent inflammation plays a key role in many of them. As the pandemic continues to evolve, it is essential to monitor its health consequences and develop effective treatments for those affected by Covid-19’s lingering impact on the human body.
