Immune response in the nose plays a role in the recovery of olfactory function after COVID-19.
An inflammatory immune response may damage olfactory sensory neurons, leading to loss of smell.
Ongoing immune responses may continue to cause inflammation and damage post-COVID-19.
A study published in Science Translational Medicine aims to improve understanding of COVID-19 symptoms.
Loss of smell, or olfactory function loss, can be normosmia, hyposmia, or anosmia.
Potential treatments for loss of smell include intranasal steroids, neuromodulating medication, and olfactory retraining.
Continuing research into COVID-19's impact on the body aims to find effective treatments.
Understanding mechanisms behind loss of smell can aid in finding key solutions for those affected.
