Many of the sufferers who misplaced their sense of scent or style following a COVID an infection nonetheless haven’t absolutely recovered these senses, in accordance with a brand new examine out of Massachusetts Eye and Ear.
Researchers at Mass Eye and Ear appeared on the lack of olfactory and gustatory senses and estimated that about 25% of Americans who had COVID-19 reported solely partial or no restoration of style or scent.
“We wanted to quantify the national impact of smell disorders resulting from COVID,” mentioned Neil Bhattacharyya, professor of Otolaryngology at Mass Eye and Ear.
“With this data we can understand, in big numbers, how many people lost their sense of smell or taste due to COVID infection and how many people never fully recovered those senses,” Bhattacharyya added.
The researchers examined information from the 2021 National Health Interview Survey (NHIS), a CDC department, which incorporates survey information from 29,696 adults.
In the NHIS information, COVID sufferers have been requested concerning the severity of their signs, any lack of style or scent, and their restoration of these senses.

Bhattacharyya mentioned one of many motivations for the examine was his affected person who misplaced 50 kilos attributable to COVID-related scent loss.
“The patient wasn’t eating and became very sick and very depressed because of the loss of smell,” Bhattacharyya mentioned. “When you hear about COVID-related smell loss, you think most people get it back and are fine. But there is a substantial number of people who don’t recover it.”
“The value of this study is that we are highlighting a group of people who have been a bit neglected,” Bhattacharyya added. “Losing your sense of smell or taste isn’t as benign as you may think. It can lead to decreased eating for pleasure and, in more extreme cases, it can lead to depression and weight loss.”
