The loss of smell is usually treated through use of nasal sprays and in some cases surgery.
The treatment for loss of smell depends on what is causing the loss of smell and if it's allergies or nasal congestion, sinus infections or a cold then treating the loss of smell is usually done through nasal irrigation, nasal sprays and steam.
But for other causes sometimes surgery is needed to restore your loss of smell.
Your sense of smell can sometimes be restored depending on the cause of the loss of sense of smell.
if your loss of smell is a condition known as anosmia then it may or may not be possible to restore your sense of smell but sometimes anosmia is a temporary condition.
A sudden loss of smell can be caused by the common cold, flu, medications, sinus infections, stuffy nose and much more.
Most times a sudden loss of smell is caused by something less serious such as the cold or sinus infection or simply a stuffy nose.
And then later the sense of smell comes back after the cold or flu or whatever it is goes away.
Someone with no sense of smell cannot usually taste foods.
However it depends on if you have fully lost your sense of smell or just partially lost your sense of smell.
Some people who have lost their sense of smell can still taste some foods at least partially but other people who have lost their sense of smell also lost their sense of taste as well.
Your ability to taste things is linked to your ability to smell.
So when you lose your sense of smell then you can also lose your ability to taste things as well.
Losing your sense of smell can indeed alter your ability to taste certain foods so some foods you eat may not taste as good as they once did when you had a good sense of smell.
Your sense of smell does affect your taste but losing your sense of smell doesn't always completely cause a loss taste.
Most people who lose their sense of smell are still able to tell between salty, sweet, sour, and bitter.
But you do need your sense of smell to taste things correctly but you can still usually taste things even without your sense of smell.
