A NEW study will consider whether vitamin A can help those who have lost their sense of smell after having Covid-19.

The 12-week ‘Apollo trial’ will treat people who have experienced smell loss or an altered sense of smell as a result of viral infections with nasal drops containing the vitamin, the University of East Anglia (UEA) said in a statement.

The university said research from Germany had shown the potential benefit of the vitamin, and its team “will explore how this treatment works to help repair tissues in the nose damaged by viruses”.

A loss of taste and smell are among the most common symptoms associated with Covid-19.

A loss of the senses is also associated with Long Covid, also known as post-Covid syndrome, is used to describe the effects of the virus that continue for weeks or months beyond the initial illness.

Recovery from the illness, responsible for the global pandemic, can often take weeks or even months with about one in 10 cases leaving taste and smell problems after coronavirus infection.

A loss of smell will affect how people can detect flavours, when we eat, the flavour of food is the combined experience of smell and taste.

It is worth noting that the loss of smell which will also affect your taste is not usually serious and should get better after a few weeks or months.

A cold or flu, sinusitis, allergies and growths in your nose can all be causes of a lost sense of smell however un the current climate it could be a sign that you have or have had Covid-19.

If you are suffering from a loss of smell since contracting coronavirus the NHS has issued advice on how to regain your senses.

Cleaning the inside of your nose

Rinsing the inside of your nose with a saltwater solution may help if your sense of smell is affected by an infection or allergy.

Sachets for saltwater solution and devices to help rinse out your nose will be available at some pharmacies throughout the UK although the NHS has provided guidance on how to create it at home.

  1. Boil a pint of water, then leave it to cool.
  2. Mix a teaspoon of salt and a teaspoon of baking soda (bicarbonate of soda) into the water.
  3. Wash your hands.
  4. Stand over a sink, cup the palm of 1 hand and pour a small amount of the solution into it.
  5. Sniff some of the solution up 1 nostril at a time and let it run out of your nose. It might help to hold your other nostril closed with your finger as you sniff.
  6. Repeat these steps a few times to see if it helps.

You do not need to use all of the solution, but make a fresh batch each day – do not reuse any left over from the day before.

Treatment for lost or changed sense of smell

It is likely your loss of smell will return to normal in a few weeks or months whether that be through Covid-19 or through any of the other causes mentioned above.

The NHS say a treatments called “smell training” could help.

Smell training is actively sniffing the same four scents every day, spending around 20 seconds on each scent and really concentrating on what you’re doing.
