British scientists claim that vitamin A nasal drops are able to restore the sense of smell lost during coronavirus. They are undergoing clinical trials for 12 weeks.
British researchers from the University of East Anglia are conducting trials on volunteers, some of whom are receiving treatment. All participants will then inhale the strong scents of roses and rotten fish to determine, using a brain scan, whether the ability to perceive smells has returned after vitamin A, says Air force…
A change or loss of smell can be caused not only by Covid, but also by other viruses, this is a fairly common symptom. Sometimes this ability is restored after a couple of weeks, sometimes the symptom lasts for six months, and some patients may lose their sense of smell for life, scientists suggest.
There are other consequences as well. To stop smelling is far from the worst thing for people with coronavirus. Much worse when aromas after recovery become a stench… Claire Freer, a 47-year-old resident of Sutton Coldfield, describes how she felt:
“Everything started to smell awful. My bed linen smells unpleasant and makes me sick. I can’t even kiss my partner anymore. The smell of something rotten fills the house as soon as the stove is opened, and it is unbearable. The main triggers for me are onions, garlic, gravy, shower gels, and coffee. When I am near them, I feel dizzy and I cry, the smell is so unbearable! It is very hard to live with, from showering and brushing your teeth to sleeping. My family recently ate Chinese food and I had to sit outside for a while because the smell made me feel so depressed that it is very difficult to describe – it looked like a tainted perfume. “
Lina Alnadi from London developed parosmia after the coronavirus – the smell of many ordinary things for her has changed. Tap water smells like swamp or sewers, and eggs – one of Lina’s favorite foods – smells like burnt rubber:
“I had to get creative to make sure I was eating enough of the right foods to stay healthy.”
Carl Philpott, professor at the UEA Norwich School of Medicine and James Paget University Hospitals NHS Trust, lead researcher, says:
“We want to find out if the size and activity of damaged olfactory tracts in the brains of patients increases when they are treated with vitamin A nasal drops. We will look for changes in the size of the olfactory bulb – the area above the nose where the olfactory nerves connect to the brain. We will also look at activity in areas of the brain associated with smell recognition. ”
Reference. Vitamin A helps maintain the immune system, has a beneficial effect on eyesight and skin, mucous membranes, including the nose. Some vegetables and dairy products contain fat-soluble vitamin A. However, in large quantities, it can be harmful rather than beneficial.
