Sulfur, rotten onions and solvent: how the sense of smell changes after coronavirus

17.08.2020

It is well known that in case of intoxication of various etiologies, patients are always prescribed a special diet. This is done in order to reduce mechanical and chemical irritation of the gastrointestinal tract, which primarily suffer from poisoning, in order to restore the normal functioning of the digestive system, which is responsible for metabolic processes in the body, as quickly as possible.

Alcohol binge drinking is also intoxication, during which the body is poisoned by excess products of the breakdown of ethyl alcohol (in particular, acetaldehyde). Consequently, a logical question arises: what should proper nutrition be like after a binge in order to quickly restore metabolism and the functioning of internal organs affected by alcohol intoxication?

Nausea after eating eggs

According to statistics, an allergic reaction to eggs is a fairly popular pathology.

Egg white is a strong food allergen in this situation; in some cases, consuming it in small quantities leads to dangerous complications.

Allergies can be triggered not only by chicken eggs, but also by goose, duck and even quail eggs.

Therefore, when a person experiences any manifestations of allergies after eating food, or feels sick, then they should avoid consuming them and consult a specialist.

How many eggs can you eat without harming your health?

The yolk and white of an egg contain completely different substances, so recommendations for their consumption differ. A nutritionist advises a healthy person to eat a maximum of one yolk and three whites at a time. “You can also do the following: eat one egg, remove the yolk from the second and make some kind of dish,” recommends Solomatina.

If you don't eat eggs daily, you can deviate from this norm and eat a few eggs a day (but not exceeding the weekly norm). According to the results of a study by American scientists published in the medical journal JAMA, two to three eggs per week is the best option for a healthy person.

Etiology of egg allergy

Egg white contains albumin. When penetrating into the human body predisposed to allergies, it causes the production of antibodies.

It is believed that an allergic reaction occurs only after eating raw eggs, but this is a misconception.

The protein contains albumin and heat-resistant mucoid, which is also an allergen. Therefore, a reaction can be observed when eating boiled and fried eggs.

Vitellin, which is part of the yolk, is actually neutralized during heat treatment, which explains why the yolk rarely causes an allergic reaction.

It should be taken into account that certain vaccines add protein proteins, which are part of the egg.

An injection given by such a vaccine can cause a very severe reaction in a child, including the formation of anaphylactic shock or angioedema.

Certain products may contain eggs or egg components. When a patient has an allergic reaction to this type of product, you should carefully read the composition of the purchased product.

When it includes: albumin, lysozyme, vitellin, globulin, thickener, emulsifier, you should not buy it.

Often an allergic reaction to eggs is associated with a cross-allergy to chicken meat, so consumption of this product should be avoided.

List of temporarily excluded products

  • Fresh bread, any pastries, pancakes, pies and pies.
  • Fatty and stringy varieties of meat, poultry or fish, stewed, fried or smoked. Any types of canned meat or fish.
  • Fried or hard-boiled eggs, raw egg whites.
  • Any dairy products with high acidity.
  • Buckwheat in kernels, millet, barley and pearl barley, whole pasta.
  • Radishes, garlic, spinach, mushrooms, turnips. Pickled, pickled, salted vegetables. Canned vegetables and all types of legumes.
  • Soups with strong meat, mushroom or vegetable broths. Cabbage soup, okroshka, borscht, beetroot soup.
  • Margarine, beef or pork fat, lard, ghee.
  • Any spices or herbs, including those used in sauces.
  • Fruits or berries of sour varieties and/or raw.
  • Chocolate, cream cakes.
  • Coffee, strong tea or cocoa, carbonated drinks, sour juices.

Symptoms of the disease

The onset of initial symptoms is observed immediately (occasionally after a short period of time) after eating eggs or including them in products.

When initial symptoms appear, it is necessary to rinse the stomach. For these purposes, a manganese solution is used (the same concentration as during intoxication).

An allergic reaction can manifest itself with the following symptoms:

  • Redness and itching of the skin.
  • Allergy type urticaria (bright red rash).
  • Digestive tract disorders: nausea, gag reflex, stool disorders (often diarrhea).
  • Diffuse neurodermatitis.
  • Allergic runny nose.
  • Difficulty breathing, wheezing.
  • Bronchial asthma or allergic bronchitis.
  • Decreased blood pressure, fainting, dizziness.
  • The appearance of Quincke's edema (provokes intense swelling of the respiratory tract) or anaphylactic shock.

In adults, an allergic reaction to eggs, including quail eggs, is observed when there is an excess of them on the menu or a one-time consumption of a significant amount of this product.

When allergies appear in infants, they usually disappear by age 5.

Sulfur, rotten onions and solvent: how the sense of smell changes after coronavirus

Can we breathe a sigh of relief if the coronavirus is behind us? As it turned out, not always. Often, those who have recovered from the disease complain of distorted perception of smells (parosmia) and olfactory hallucinations (phantosmia). Why does this happen and what can be done? Yulia Vladimirovna Roshchupkina, a neurologist at the Expert Clinic Tula, told us about this.

Yulia Vladimirovna, what are olfactory hallucinations, what are they?

– These are deceptions of smell, that is, the perception of a smell that is absent in reality. People can smell neutral, aversive, and pleasant aromas. Many patients who suffered from long-term COVID-19 complained of “disgusting smells of fish, sulfur.” Some began to smell a “sweetish, unpleasant odor.”

Why do such hallucinations appear after coronavirus infection?

– This side effect was explained by the fact that SARS-CoV-2 is a neurotropic virus. The reason for the distortion of odors is always either damage to the olfactory receptors or impaired identification of odors by the cerebral cortex.

What is the risk that a person will experience olfactory hallucinations after illness? Is there any way to reduce this probability?

– According to doctors, after recovering from COVID-19, many experience olfactory hallucinations and parosmia. Most often, this happens to people who have completely lost their sense of smell for some time during illness. Sometimes for those who previously experienced loss of smell and taste, this symptom appears weeks or even months after recovery.

COVID-19 is a very insidious disease. It affects all organs, including nerve endings, causing the perception of aromas to become distorted. This does not manifest itself in all those who have recovered from the disease, and the reason for this selectivity has not yet been conclusively established. There is a hypothesis that olfactory hallucinations are one of the stages of recovery of the nervous system after an illness. When at least three to five years have passed since the first clinical cases were recorded and reliable statistical data can be obtained, we may be able to answer the question of how to reduce the risk of parosmia and phantosmia.

Will the hallucinations go away and how soon?

– According to Italian scientists, after COVID-19, the normal functioning of olfactory receptors is restored on average in eighty days. Their colleagues from Germany talk about sixty days. But distortions due to impaired function of the cerebral cortex can last indefinitely. For people whose cortical part of the analyzer has been affected by the virus, it may take up to six months to return to normal sensations. The average time for smells to return is one to two months.

Are there any recommendations for restoring normal sense of smell and getting rid of hallucinations?

– The problem is extremely urgent, but scientists have not yet found an optimal solution for it. All over the world, residual effects and features of post-Covid rehabilitation continue to be studied.

Doctor of Medical Sciences, infectious disease specialist Natalya Vorobyova says that the restoration of olfactory and taste neurons and their receptors will take some time, and this is determined by the processes of neuroplasticity.

To restore your sense of smell, experts from the charity AbScent, which supports people with parosmia and anosmia, advise training it: inhale essential oils of rose, clove and lemon for 20 seconds every day. The nose and brain will seem to be reacquainted with smells and remember them. Don't forget about peace of mind and mental health: meditate, try different relaxation practices, consult a psychologist or psychotherapist. Otherwise, a vicious circle is formed: significant disturbances in the sense of smell lead to severe stress, and stress, in turn, worsens well-being.

Which doctor should I go to if hallucinations do not go away?

– As a rule, if the sense of smell is partially restored, there is a good prognosis for the restoration of the sense of smell in general. If olfactory disturbances turn out to be persistent, you should contact an otolaryngologist and neurologist to exclude other possible causes of phantosmia or parosmia.

If the rehabilitation period is prolonged, the patient may be prescribed a course of treatment aimed at restoring peripheral nerves. As a rule, it includes anticholinesterase drugs, special vitamin preparations and drugs that improve microcirculation.

Is it dangerous to ignore olfactory hallucinations?

– Of course it’s dangerous! After all, hallucinations after COVID-19 are often delayed, and people sometimes mistake the symptoms of another disease for complications of a previous coronavirus infection.

The most common cause of olfactory hallucinations is brain damage. It can be caused by traumatic brain injury, cancer affecting one or another part of the brain, stroke, or neuroinfection.

Other unfavorable factors include: • mental illness (such as schizophrenia, personality disorder); • epilepsy; • intoxication of the body; • the influence of potent medications, psychotropic or narcotic drugs; • damage to the mucous membrane of the nasal sinuses; • dental problems; • diseases of the gastrointestinal tract.

There are many people who turn a blind eye to olfactory illusions for many years, without thinking about the impending danger.

There are three main ways to determine what is causing a symptom: • MRI of the brain • CT scan of the brain • EEG

Avoiding eating eggs

First of all, a person should completely avoid eating eggs and products made from them.

Such products include mayonnaise, ice cream, meat and confectionery products, various types of flour and pasta. When preparing dishes, eggs can be replaced with the following components:

  • Dry yeast (30 g) is diluted with 50 g of warm water.
  • Add 2 tbsp. l. banana puree.
  • Take 3 tsp. sunflower oil and hot water, mixed with 1 tsp. soda
  • 1 sachet of gelatin is diluted in 50 g of water.

Diet food

The menu for children or adults who are susceptible to unpleasant reactions to the components of egg products includes the following items:

  • Vegetable soups or soups that are prepared in broth from dietary meats.
  • Various kinds of vegetables.
  • A variety of fruits (if there is no allergic reaction to them).
  • Porridges that are prepared from various cereals (porridge cooked in a pan where the egg was boiled becomes allergenic).
  • Lean meats.
  • It is acceptable to use homemade flour products that do not contain eggs.
  • Consumption of fermented milk products helps to compensate for the lack of microparticles and vitamins.

Drug therapy

Allergies cannot be eliminated through medications. Antihistamines (antiallergic) medications are used mainly for the symptomatic treatment of allergies.

Tavegil, Suprastin, which are 1st generation drugs, Zyrtec, Claritin (2nd generation drugs), Astemizole, Terfinadine (3rd generation drugs), are often used.

In the process of developing such a reaction, it is necessary to remove eggs and products containing them from the diet, as well as consult with a specialized doctor for the purpose of diagnosis and selection of appropriate therapy.

Often, such a reaction to this product can occur without pronounced symptoms and not cause a person any unpleasant discomfort until the proteins that eggs are rich in enter the body.

It happens inside of us

The body does not recover immediately after suffering intoxication, because toxic substances already had a detrimental effect on almost all organs. Often after poisoning, the stomach hurts - this is explained by the fact that the gastric mucosa becomes inflamed - acute gastritis develops. The stomach stops doing its usual job - digesting food. Nausea, belching and pain appear after poisoning. Poorly digested food enters the intestines. And he, of course, is “dissatisfied” with the poor functioning of the stomach, and his “indignation” is manifested by bloating, gurgling and diarrhea after poisoning.

First of all, the liver suffers from intoxication: it works around the clock, seven days a week, neutralizing toxic substances that enter the body. “Fatigue” of the liver may be indicated by heaviness in the right side, yellowness of the skin, bitterness in the mouth, and elevated temperature after poisoning. During the period while recovery from poisoning is underway, general weakness, pain in muscles and joints, poor appetite, insomnia and other symptoms may bother you.

During the recovery period, medications are prescribed that improve digestion processes (enzymes) and the intestinal sorbent Enterosgel, which neutralizes and removes toxic molecules.

To restore beneficial intestinal bacteria, doctors prescribe effective tablets after poisoning - probiotics.
