Fainting or dizziness. Constant and sufficient supply of oxygen is required by the brain to function properly. However, a blood clot that results to insufficient flow of blood to the brain will mean a reduced amount of oxygen is being delivered to the organ. Inadequate oxygen in the brain can lead to fainting. The current review explains that in people with COVID-19, a shortened blood flow transit time in the capillaries limits the amount of oxygen that can be delivered to the lungs and brain. The glucose transporter built into the blood-brain barrier, which regulates the flow of nutrients into and out of the brain, allows it to continuously take in glucose even when blood glucose levels are low. Food consumption is the brain’s primary energy source because it cannot generate or store energy like other organs like the liver or muscles.
