Common causes of smell loss include allergies, injury to the nerve tissue from an upper respiratory infection, and rhinitis.

Smell Loss


The two most common causes of a loss of smell are allergies or some kind of injury to the nerve tissue from a viral upper respiratory infection. Patients who lose their sense of smell as a result of a respiratory infection will generally be able to date the time of their smell loss to the same time as the respiratory infection they experienced. In general, these tend to be older patients, and the loss of smell that they have incurred is more typically partial than total in nature.

Unfortunately, there is no effective treatment for this situation because viral damage cannot normally be repaired. While it is possible that some patients will recover their sense of smell over time, these patients are definitely in the minority, and comprise less than 20% of the total number of patients experiencing smell loss. It is however, certainly possible that people who experience temporary smell loss after an upper respiratory infection recover it within a few days of being restored to normal health from the infection.

Smell Loss from Sinuses or Allergies

The other most common cause of smell loss is rhinitis, which is an inflammation that occurs in the nose, nasal polyps, or sinusitis. All three of these are considered to be ongoing processes, in that they recur during the lifetime of the patient, and as such, have an ongoing effect on the sense of smell.

Since this is the case, the development of smell loss tends to be a much more drawn-out process, as opposed to the upper respiratory infection cases, which are more spontaneous in nature. People who are troubled with smell loss due to allergies or sinus problems often report improvements in their sense of smell on a temporary basis, for instance after vigorous exercise, showering, or some other activity which elevates one’s heart rate.

It’s also possible for temporary smell improvements to be experienced when taking corticosteroids, antibiotics, or some other kinds of medication, but, in most cases, the improvement eventually subsides, and the loss of smell returns. It’s fairly common in such cases for there to be accompanying symptoms such as post-nasal drip, problems with breathing through the nose, or nasal allergies. Interestingly, the development of smell loss does not result in a loss of taste, or at least that has not been reported by any significant number of studied patients.

For people who have experienced both an upper respiratory infection and an ongoing process like sinusitis, it will usually be very difficult to pinpoint the time of your smell loss. There is a reason, though, that dating the time of smell loss can be important, because of the two types of smell loss, only sinusitis is treatable and reversible. As previously mentioned, viral damage to the nose cannot be repaired, and that means the sense of smell will also be unlikely to improve for the vast majority of patients.

Treatments for Smell Loss

When a doctor is able to determine whether a patient’s loss of smell was triggered by allergies, there are some treatments which may help recover and restore the sense of smell. Antihistamines, antibiotics, and corticosteroids have all proven to be at least somewhat effective in restoring the sense of smell, because they work to decrease inflammation in the nasal passageways, and these are the primary causes of smell loss in the first place.

For patients who have had some physical damage to the nose, such as a deviated septum or nasal polyps, surgery may also be an option to repair the problem. However, the correlation between surgery and successful restoration of the sense of smell is not strong, so for any specific situation, a patient should discuss surgical options with their doctor.

Patients who have suffered a loss of smell following some kind of severe trauma to the nose or an upper respiratory viral illness, have very few treatment options available to them currently. Corticosteroids are sometimes used to provide benefits for some patients, but the success rate is not particularly promising.

New research has shown that attempting to retrain a person’s sense of smell can achieve modest successes, since it attempts to stimulate the regenerative capabilities of the body’s olfactory network. Part of this therapy involves exposing a patient to familiar odors which are very strong and recognizable, so as to promote the recovery of a sense of smell. The theory behind this is that it helps to rewire that area of the brain which processes smells.

Currently, research is underway to explore other avenues for the restoration of the sense of smell in patients who were thought to have experienced total loss. While medical treatments have not been shown to be universally effective, some patients have experienced small gains in their sense of smell when using phentoxifylline, gabapentin, theophylline, various antidepressants, and some kinds of antibiotics. In the future, it is likely that other treatment approaches will be discovered, and that many more patients will be able to cover some sense of smell even after a traumatic upper respiratory viral infection.

Pet Allergies: Causes and Prevention


Some things stay controversial, and the debate over pets and allergies has been going on for some time. Can you have pets when you have allergies? How will it affect you? Why do pets trigger allergies in the first place? Since our furry, feathery friends can add so much to our lives, it seems sad we should be restricted due to such a common health issue like pet allergies.

What Causes Pet Allergies?

Before we go any further, we should note that everybody is unique so will have different types of pet allergies and different things that set off the condition. For example, some people might be allergic to just dogs while others are allergic to cats, horses, hamsters, guinea pigs, mice, rabbits, gerbils, and even birds.

When it comes to pet allergies themselves, they commonly develop in children, but they can also show at any stage of life. Even if you had a cat for the first twenty years of your life with no problems, you could still get a cat at 40 and suddenly see a reaction. Regardless of when it develops, pet allergies are what we call ‘allergic asthma.’ Proteins from their skin, known as ‘dander,’ irritate your immune system.

If you’re sensitive to these particular proteins, the immune system overreacts after touching or inhaling the allergen and this releases histamine thus leading to an allergic reaction. If you have allergies or asthma, the release of histamines will worsen the symptoms.

If you have pet allergies and want to become a pet owner, fear not! There are ways to control pet dander and allergens in your home. You can also speak to a vet or your allergist to see if there is a compatible pet for you that won’t irritate your allergies.

An Overview

Unfortunately, family pets can be a trigger of allergy and asthma attacks, but this doesn’t mean you need to give up your pet or put your dream of having a pet aside just yet. First things first, talk with your doctor, and they should be able to assess the severity of your case. From here, you should consult with your vet. Since physicians aren’t typically trained giving you advice for living with pets, professional vets will probably provide you with the best opportunity to live harmoniously.

As you work with your vet, they’re likely to present you with tips that’ll lessen the effects of having the pet and, hopefully, reduce the symptoms you see. For example, regular vacuuming to control pet dander will be necessary, as will keeping your pet from your bedroom. Considering you need to avoid the allergen to prevent an allergy attack, it’s best to keep your pet from living spaces, so you have allergen-free sections of your home.

Furthermore, your vet will recommend keeping all bedding clean while also considering dust mite covers, and this is because dust mites enjoy eating pet dander. As an alternative solution, you can try some shampoos and sprays on the market that have been designed to neutralize all dander. Ultimately, it’s about being sensible and doing all you can to avoid pet dander from ruling your home.

Talk To Your Doctor or Allergist

If the tips above haven’t helped or you’ve tried them before, it’s now time to talk with your doctor again because they should help you to find what’s actually causing the allergy symptoms. Rather than assuming the pet is the cause, the doctor should be able to test for pet allergies to see the primary contributing factor to your allergies. From here, they can suggest advice, or you may find that your condition just doesn’t allow you to live safely with your current pet. If you need to find a new home for your friend, your vet should be able to help you with this.

As we’ve said previously, this doesn’t mean you can’t have a little companion by your side because all pets are different. While all dogs (and other pets) shed, some will shed less than others. These pets may be more compatible with your health concerns. With these hypoallergenic pet breeds, you might be able to live comfortably by applying the tips listed previously.

Ultimately, we recommend spending time with the type of pet you wish to adopt so you can learn whether you can both live happily together. If the pet doesn’t trigger your allergies, you may just have found a new home for a pet and a happy future for yourself. Before committing though, we recommend taking them home and spending time together in different environments just to be sure.

Are Allergies Genetic?


Are allergies genetic, hereditary, developed over time? No matter how you ask it, you seem to have stumbled across one of the most popular questions regarding allergies (after “how do I cope with allergies because they’re driving me crazy,”of course). Whether you’re starting to develop similar allergies to your parents or perhaps you’re noticing the signs in your own children, you might be wondering whether allergies can be passed down from one generation to the next. 

To answer this question, we first need to deal with the word “allergy” and what it actually means. In truth, it’s quite a broad term and covers any abnormal reaction to substances that are, generally speaking, harmless to the masses. Known as ˜allergens,”these substances can be found outside, inside, in our foods, and in a variety of other locations in life. 

With each allergen offering something different, the reactions and symptoms of a reaction can be very different. For pollen, for example, you might experience a runny nose, red eyes, itchy ears, watery eyes, scratchy throat, or perhaps something else. With animal dander, dust mites, and mold, the symptoms are very similar but may vary in how often one occurs over the other. Finally, more severe symptoms can include coughs, sinus headaches, and facial pain.

To what extent are allergies genetic? Allergies may not be passed down from parent to child, but there is definitely a genetic correlation. Twins, for example, are usually allergic to similar things.

True or False: Are Allergies Genetic?

So, to what extent are allergies genetic? All things considered, there are many ways in which we can develop allergies and our genes are included in this list. Often, parents will pass these allergy genes to their children who will then suffer the same (or similar) allergies throughout their life. Of course, this isn’t to say that, if you have allergies, your children or potential children will definitely develop the same allergies. While some children will develop them, others will develop different allergies, while a third group won’t develop any allergies at all so each case is unique. 

At this point, we should note that the allergy cannot be passed from parent to child. In what sense then, are allergies genetic? Instead, it’s the tendency to be allergic to a certain substance that’s passed on. Today, this is a common misconception even though the difference is quite significant. 

Overall, we can say that children belonging to parents with allergies are more likely to see allergies themselves. This being said, it’s important for all parents to have their children tested for the same allergies if any symptoms show. As long as you’re alert and aware of your child’s behavior, you can approach your doctor and have the best case of treatment installed. To diagnose allergies, the doctor will ask for the medical history of your child (or yourself if you’re experiencing the symptoms) before then performing certain physical tests. If allergies are present but the doctor can’t quite pinpoint the issue, allergy skin testing may be used. 

As soon as the issue has been highlighted, the right treatment can be put into place to keep the allergies under control in the time ahead. Rather than ignoring it and hoping for the best, medication can control the allergies and make the experience a little easier to bear.

Allergen Immunotherapy

Regardless of whether it’s your children, yourself, or even a friend or family member, your doctor might also recommend allergen immunotherapy. If the issue is severe and affecting everyday life, this treatment will gradually desensitize the body to the allergen causing the problems. As the body starts to recover, not as much medication will be required and the symptoms should reduce. 

Studies and Research

A recent study in The Journal of Allergy and Clinical Immunology noted how allergies can also be gender-related as well as just inherited. For the longest time, it was assumed all allergies came from the mother. With this discovery, it means the mother is more likely to pass allergies to her daughter while a father is more likely to pass allergies to his son.

Finally, there has also been some interesting research on twins. If they share the same 25,000 genes (identical twins), there’s a 60% chance of both being allergic to peanuts if one is allergic to peanuts. If only 50% of the genes are shared (fraternal twins), this rate decreases to just 7%. 

Ultimately, as we’ve seen all the way through, genes do play a role in passing these allergies along. However, this role is still largely undefined and we’ll only find out how it all works when researchers make a substantial breakthrough!
