Long COVID's hidden toll: Brain fog, aging, and lingering symptoms explained

Recovered COVID-19 patients often face lingering health issues. The virus can trigger long-term effects, including premature aging and cognitive decline. Many continue to experience symptoms such as headaches, dizziness, and loss of smell. The coronavirus disrupts normal lung function, reducing oxygen delivery to the brain. This can lead to encephalopathy, a condition affecting brain health. The disease also increases the risk of pulmonary thrombosis, further complicating recovery.

The olfactory nerve, which controls the sense of smell, is frequently damaged. This explains why many patients lose their ability to detect odours. Over time, some may develop brain tissue degeneration, impacting memory and thinking.

Doctors advise recovered patients to rebuild their immune systems. Regular exercise, a balanced diet, and healthy habits can help. Those with vitamin deficiencies are encouraged to eat more fruits and vegetables. These steps may also slow premature aging caused by the virus. COVID-19 leaves a lasting mark on the body. Strengthening immunity and improving lifestyle habits can reduce long-term risks. Better health choices may help prevent complications like cognitive decline and early aging.
