What kind of symptoms can allergies cause

Sinusitis is an infection or inflammation of the sinuses. A sinus is a hollow space.

What helpful of symptoms can allergies cause

There are numerous sinuses in the body, including four pairs inside the skull. They serve to lighten the skull and give resonance to the voice. These sinuses are lined with the same helpful of tissue that lines the inside of the nose. The same things that can cause swelling in the nose – such as allergies or infection – can also affect the sinuses. When the tissue inside the sinuses becomes inflamed, mucus discharge is increased.

Over time, air trapped inside the swollen sinuses can create painful pressure inside the head. This is a sinus headache.

SYMPTOMS OF AN ALLERGIC REACTION

The severity of symptoms during an allergic reaction can vary widely. Some of the symptoms of an allergic reaction include:

  1. Diarrhea
  2. Hives (a rash with raised red patches)
  3. Rashes
  4. Itchy, watery eyes
  5. Stomach cramps
  6. Sneezing
  7. Itchy nose
  8. Vomiting
  9. Runny nose
  10. Bloating
  1. Feeling faint, light-headed or “blacking out”
  2. Throat closing
  3. Cough
  4. Swelling
  5. Wheezing (a whistling sound when you breathe)
  6. Pain
  7. Redness
  8. Chest tightness and losing your breath
  9. Tongue swelling
  10. A sense of “impending doom”

Some of these symptoms can be sign of a life-threatening allergic reaction.

To prevent a reaction, it is extremely significant to avoid every fish and fish products.

Always read food labels and enquire questions about ingredients before eating a food that you own not prepared yourself.

Steer clear of seafood restaurants, where there is a high risk of food cross-contact. You should also avoid touching fish and going to fish markets. Being in any area where fish are being cooked can put you at risk, as fish protein could be in the steam.

More than half of people who are allergic to one type of fish are also allergic to other fish.

Your allergist will generally recommend you avoid every fish. If you are allergic to a specific type of fish but desire to eat other fish, talk to your doctor about further allergy testing.

Fish is one of the eight major allergens that must be listed on packaged foods sold in the U.S., as required by federal law.

There are more than 20,000 species of fish. Although this is not a finish list, allergic reactions own been commonly reported to:

  1. Tilapia
  2. Salmon
  3. Perch
  4. Catfish
  5. Pollock
  6. Haddock
  7. Anchovies
  8. Sole

  15. Flounder
  16. Grouper
  17. Hake
  18. Snapper
  19. Halibut
  20. Trout
  21. Mahi mahi
  22. Tuna

Also avoid these fish products:

  1. Fish oil
  2. Fish gelatin, made from the skin and bones of fish
  3. Fish sticks (some people make the error of thinking these don’t contain genuine fish)

Some Unexpected Sources of Fish

  1. Worcestershire sauce
  2. Caponata, a Sicilian eggplant relish
  3. Caesar salad and Caesar dressing
  4. Barbecue sauce
  5. Imitation or artificial fish or shellfish (e.g., surimi, also known as “sea legs” or “sea sticks”)
  6. Bouillabaisse
  7. Certain cuisines (especially African, Chinese, Indonesian, Thai and Vietnamese)—even if you order a fish-free dish, there is high risk of cross-contact

Allergens are not always present in these food and products, but fish can appear in surprising places.

Again, read food labels and enquire questions if you’re ever unsure about an item’s ingredients.


What Are Eye Allergies?

Eye allergies are common. Eye allergies are a reaction to indoor and outdoor allergens that get into your eyes.The tissue that lines the inside of the eyelid and exterior of the eyeball becomes inflamed and swollen and leads to itching, redness, tearing and irritation of the eyes.


What Is Rhinitis (Nasal Allergies)?

The expression rhinitis means “inflammation of the nose.” When the nose becomes irritated by allergens or irritants, it may produce more and thicker mucus than usual.

This drainage can irritate the back of the throat and cause coughing. Allergic reactions can also cause congestion, itchy nose or throat, sneezing, a runny nose and itchy, watery eyes.


What Is Anaphylaxis?

Anaphylaxis (anna-fih-LACK-sis) is a severe allergic reaction that can be life-threatening and requires immediate medical attention. It happens quick and may cause death.

What helpful of symptoms can allergies cause

Symptoms generally involve more than one part of the body, such as the skin or mouth, the lungs, the heart and the gut. Study more about anaphylaxis.


What Are Skin Allergies?

Skin allergies happen when your skin comes in contact with an allergen that your skin is sensitive or allergic to. Also, allergies to other things, love food you eat or proteins you inhale or touch, may cause symptoms to appear on your skin. The allergic reaction generally appears within 48 hours after the initial exposure to the allergen. Symptoms often include the following: redness, swelling, blistering, itching, hives and rashes. The allergen doesn’t own to be new to you. It can be something you’ve been using or eating for numerous years.

Common skin allergies include allergic contact dermatitis, eczema, chronic urticaria and angioedema.


Severe allergic reaction (anaphylaxis)

In rare cases, an allergy can lead to a severe allergic reaction, called anaphylaxis or anaphylactic shock, which can be life threatening.

This affects the whole body and usually develops within minutes of exposure to something you’re allergic to.

Signs of anaphylaxis include any of the symptoms above, as well as:

Anaphylaxis is a medical emergency that requires immediate treatment.

What is an allergy blood test?

Allergies are a common and chronic condition that involves the body’s immune system. Normally, your immune system works to fight off viruses, bacteria, and other infectious agents. When you own an allergy, your immune system treats a harmless substance, love dust or pollen, as a threat. To fight this perceived threat, your immune system makes antibodies called immunoglobulin E (IgE).

Substances that cause an allergic reaction are called allergens.

Besides dust and pollen, other common allergens include animal dander, foods, including nuts and shellfish, and certain medicines, such as penicillin. Allergy symptoms can range from sneezing and a stuffy nose to a life-threatening complication called anaphylactic shock. Allergy blood tests measure the quantity of IgE antibodies in the blood. A little quantity of IgE antibodies is normal.

What helpful of symptoms can allergies cause

A larger quantity of IgE may mean you own an allergy.

Other names: IgE allergy test, Quantitative IgE, Immunoglobulin E, Entire IgE, Specific IgE

Medications

Many allergens that trigger allergic rhinitis are airborne, so you can’t always avoid them. If your symptoms can’t be well-controlled by simply avoiding triggers, your allergist may recommend medications that reduce nasal congestion, sneezing, and an itchy and runny nose. They are available in numerous forms — oral tablets, liquid medication, nasal sprays and eyedrops.

What helpful of symptoms can allergies cause

Some medications may own side effects, so discuss these treatments with your allergist so they can assist you live the life you want.

Immunotherapy

Immunotherapy may be recommended for people who don’t reply well to treatment with medications or who experience side effects from medications, who own allergen exposure that is unavoidable or who desire a more permanent solution to their allergies. Immunotherapy can be extremely effective in controlling allergic symptoms, but it doesn’t assist the symptoms produced by nonallergic rhinitis.

Two types of immunotherapy are available: allergy shots and sublingual (under-the-tongue) tablets.

  1. Allergy shots: A treatment program, which can take three to five years, consists of injections of a diluted allergy extract, istered frequently in increasing doses until a maintenance dose is reached.

    Then the injection schedule is changed so that the same dose is given with longer intervals between injections. Immunotherapy helps the body build resistance to the effects of the allergen, reduces the intensity of symptoms caused by allergen exposure and sometimes can actually make skin test reactions vanish. As resistance develops over several months, symptoms should improve.

  2. Sublingual tablets: This type of immunotherapy was approved by the Food and Drug istration in 2014. Starting several months before allergy season begins, patients dissolve a tablet under the tongue daily.

    What helpful of symptoms can allergies cause

    Treatment can continue for as endless as three years. Only a few allergens (certain grass and ragweed pollens and home dust mite) can be treated now with this method, but it is a promising therapy for the future.

Nasal sprays

Nonprescription saline nasal sprays will assist counteract symptoms such as dry nasal passages or thick nasal mucus. Unlike decongestant nasal sprays, a saline nasal spray can be used as often as it is needed.

Sometimes an allergist may recommend washing (douching) the nasal passage. There are numerous OTC delivery systems for saline rinses, including neti pots and saline rinse bottles.

Nasal cromolyn blocks the body’s release of allergy-causing substances. It does not work in every patients. The full dose is four times daily, and improvement of symptoms may take several weeks. Nasal cromolyn can assist prevent allergic nasal reactions if taken prior to an allergen exposure.

Nasal ipratropium bromide spray can assist reduce nasal drainage from allergic rhinitis or some forms of nonallergic rhinitis.

Decongestants

Decongestants assist relieve the stuffiness and pressure caused by swollen nasal tissue.

They do not contain antihistamines, so they do not cause antihistaminic side effects. They do not relieve other symptoms of allergic rhinitis. Oral decongestants are available as prescription and nonprescription medications and are often found in combination with antihistamines or other medications. It is not unusual for patients using decongestants to experience insomnia if they take the medication in the afternoon or evening. If this occurs, a dose reduction may be needed. At times, men with prostate enlargement may encounter urinary problems while on decongestants. Patients using medications to manage emotional or behavioral problems should discuss this with their allergist before using decongestants.

Patients with high blood pressure or heart disease should check with their allergist before using. Pregnant patients should also check with their allergist before starting decongestants.

Nonprescription decongestant nasal sprays work within minutes and final for hours, but you should not use them for more than a few days at a time unless instructed by your allergist. Prolonged use can cause rhinitis medicamentosa, or rebound swelling of the nasal tissue. Stopping the use of the decongestant nasal spray will cure that swelling, provided that there is no underlying disorder.

Oral decongestants are found in numerous over-the-counter (OTC) and prescription medications, and may be the treatment of choice for nasal congestion.

They don’t cause rhinitis medicamentosa but need to be avoided by some patients with high blood pressure. If you own high blood pressure or heart problems, check with your allergist before using them.

Intranasal corticosteroids

Intranasal corticosteroids are the single most effective drug class for treating allergic rhinitis. They can significantly reduce nasal congestion as well as sneezing, itching and a runny nose.

Ask your allergist about whether these medications are appropriate and safe for you. These sprays are designed to avoid the side effects that may happen from steroids that are taken by mouth or injection.

Take care not to spray the medication against the middle portion of the nose (the nasal septum). The most common side effects are local irritation and nasal bleeding. Some older preparations own been shown to own some effect on children’s growth; data about some newer steroids don’t indicate an effect on growth.

Leukatriene pathway inhibitors

Leukotriene pathway inhibitors (montelukast, zafirlukast and zileuton) block the action of leukotriene, a substance in the body that can cause symptoms of allergic rhinitis.

These drugs are also used to treat asthma.

Antihistamines

Antihistamines are commonly used to treat allergic rhinitis.

What helpful of symptoms can allergies cause

These medications counter the effects of histamine, the irritating chemical released within your body when an allergic reaction takes put. Although other chemicals are involved, histamine is primarily responsible for causing the symptoms. Antihistamines are found in eyedrops, nasal sprays and, most commonly, oral tablets and syrup.

Antihistamines assist to relieve nasal allergy symptoms such as:

  1. Eye itching, burning, tearing and redness
  2. Sneezing and an itchy, runny nose
  3. Itchy skin, hives and eczema

There are dozens of antihistamines; some are available over the counter, while others require a prescription.

Patients reply to them in a wide variety of ways.

Generally, the newer (second-generation) products work well and produce only minor side effects. Some people discover that an antihistamine becomes less effective as the allergy season worsens or as their allergies change over time. If you discover that an antihistamine is becoming less effective, tell your allergist, who may recommend a diverse type or strength of antihistamine. If you own excessive nasal dryness or thick nasal mucus, consult an allergist before taking antihistamines.

Contact your allergist for advice if an antihistamine causes drowsiness or other side effects.

Proper use: Short-acting antihistamines can be taken every four to six hours, while timed-release antihistamines are taken every 12 to 24 hours. The short-acting antihistamines are often most helpful if taken 30 minutes before an anticipated exposure to an allergen (such as at a picnic during ragweed season). Timed-release antihistamines are better suited to long-term use for those who need daily medications.

Proper use of these drugs is just as significant as their selection. The most effective way to use them is before symptoms develop. A dose taken early can eliminate the need for numerous later doses to reduce established symptoms. Numerous times a patient will tell that he or she “took one, and it didn’t work.” If the patient had taken the antihistamine regularly for three to four days to build up blood levels of the medication, it might own been effective.

Side effects: Older (first-generation) antihistamines may cause drowsiness or performance impairment, which can lead to accidents and personal injury.

Even when these medications are taken only at bedtime, they can still cause considerable impairment the following day, even in people who do not feel drowsy. For this reason, it is significant that you do not drive a car or work with dangerous machinery when you take a potentially sedating antihistamine. Some of the newer antihistamines do not cause drowsiness.

A frequent side effect is excessive dryness of the mouth, nose and eyes.

Less common side effects include restlessness, nervousness, overexcitability, insomnia, dizziness, headaches, euphoria, fainting, visual disturbances, decreased appetite, nausea, vomiting, abdominal distress, constipation, diarrhea, increased or decreased urination, urinary retention, high or low blood pressure, nightmares (especially in children), sore throat, unusual bleeding or bruising, chest tightness or palpitations.

Men with prostate enlargement may encounter urinary problems while on antihistamines. Consult your allergist if these reactions occur.

Important precautions:

  1. While antihistamines own been taken safely by millions of people in the final 50 years, don’t take antihistamines before telling your allergist if you are allergic to, or intolerant of, any medicine; are pregnant or intend to become pregnant while using this medication; are breast-feeding; own glaucoma or an enlarged prostate; or are ill.
  2. Know how the medication affects you before working with heavy machinery, driving or doing other performance-intensive tasks; some products can slow your reaction time.
  3. Keep these medications out of the reach of children.
  4. Follow your allergist’s instructions.
  5. Some antihistamines appear to be safe to take during pregnancy, but there own not been enough studies to determine the absolute safety of antihistamines in pregnancy.

    Again, consult your allergist or your obstetrician if you must take antihistamines.

  6. Alcohol and tranquilizers increase the sedation side effects of antihistamines.
  7. Do not use more than one antihistamine at a time, unless prescribed.
  8. Never take anyone else’s medication.

Eye allergy preparations and eyedrops

Eye allergy preparations may be helpful when the eyes are affected by the same allergens that trigger rhinitis, causing redness, swelling, watery eyes and itching. OTC eyedrops and oral medications are commonly used for short-term relief of some eye allergy symptoms.

They may not relieve every symptoms, though, and prolonged use of some of these drops may actually cause your condition to worsen.

Prescription eyedrops and oral medications also are used to treat eye allergies. Prescription eyedrops provide both short- and long-term targeted relief of eye allergy symptoms, and can be used to manage them.

Check with your allergist or pharmacist if you are unsure about a specific drug or formula.

Severe allergic reaction (anaphylaxis)

In rare cases, an allergy can lead to a severe allergic reaction, called anaphylaxis or anaphylactic shock, which can be life threatening.

This affects the whole body and usually develops within minutes of exposure to something you’re allergic to.

Signs of anaphylaxis include any of the symptoms above, as well as:

Other names: IgE allergy test, Quantitative IgE, Immunoglobulin E, Entire IgE, Specific IgE

Avoidance

The first approach in managing seasonal or perennial forms of hay fever should be to avoid the allergens that trigger symptoms.

Outdoor exposure

  1. Don’t hang clothing outdoors to dry; pollen may cling to towels and sheets.
  2. Wear glasses or sunglasses when outdoors to minimize the quantity of pollen getting into your eyes.
  3. Avoid using window fans that can draw pollens and molds into the house.
  4. Stay indoors as much as possible when pollen counts are at their peak, generally during the midmorning and early evening (this may vary according to plant pollen), and when wind is blowing pollens around.
  5. Wear a pollen mask (such as a NIOSH-rated 95 filter mask) when mowing the lawn, raking leaves or gardening, and take appropriate medication beforehand.
  6. Try not to rub your eyes; doing so will irritate them and could make your symptoms worse.

Indoor exposure

  1. To limit exposure to mold, hold the humidity in your home low (between 30 and 50 percent) and clean your bathrooms, kitchen and basement regularly.

    Use a dehumidifier, especially in the basement and in other damp, humid places, and empty and clean it often. If mold is visible, clean it with mild detergent and a 5 percent bleach solution as directed by an allergist.

  2. Reduce exposure to dust mites, especially in the bedroom. Use “mite-proof” covers for pillows, comforters and duvets, and mattresses and box springs. Wash your bedding frequently, using boiling water (at least 130 degrees Fahrenheit).
  3. Keep windows closed, and use air conditioning in your car and home. Make certain to hold your air conditioning unit clean.
  4. Clean floors with a damp rag or mop, rather than dry-dusting or sweeping.

Exposure to pets

  1. If you are allergic to a household pet, hold the animal out of your home as much as possible.

    If the pet must be inside, hold it out of the bedroom so you are not exposed to animal allergens while you sleep.

  2. Wash your hands immediately after petting any animals; wash your clothes after visiting friends with pets.
  3. Close the air ducts to your bedroom if you own forced-air or central heating or cooling. Replace carpeting with hardwood, tile or linoleum, every of which are easier to hold dander-free.

Treatments that are not recommended for allergic rhinitis

  1. Antibiotics: Effective for the treatment of bacterial infections, antibiotics do not affect the course of uncomplicated common colds (a viral infection) and are of no benefit for noninfectious rhinitis, including allergic rhinitis.
  2. Nasal surgery: Surgery is not a treatment for allergic rhinitis, but it may assist if patients own nasal polyps or chronic sinusitis that is not responsive to antibiotics or nasal steroid sprays.

What Are the Symptoms of an Allergy?

An allergy occurs when the body’s immune system sees a substance as harmful and overreacts to it.

The symptoms that result are an allergic reaction. The substances that cause allergic reactions are allergens. Allergens can get into your body numerous ways to cause an allergic reaction.

  1. Your body can own allergens injected into it. This includes medicine given by needle and venom from insect stings and bites.
  2. You can ingest allergens by mouth. This includes food and medicines you eat or swallow.
  3. You can inhale allergens into your nose and your lungs. Many are little enough to float through the air.

    What helpful of symptoms can allergies cause

    Examples are pollen, home dust, mold spores, cat and dog dander and latex dust.

  4. Your skin can absorb allergens. Plants such as poison ivy, sumac and oak can cause reactions when touched. Latex, metals, and ingredients in beauty care and household products are other examples.


Main allergy symptoms

Common symptoms of an allergic reaction include:

  1. tummy pain, feeling ill, vomiting or diarrhoea
  2. a raised, itchy, red rash (hives)
  3. wheezing, chest tightness, shortness of breath and a cough
  4. sneezing and an itchy, runny or blocked nose (allergic rhinitis)
  5. swollen lips, tongue, eyes or face
  6. itchy, red, watering eyes (conjunctivitis)
  7. dry, red and cracked skin

The symptoms vary depending on what you’re allergic to and how you come into contact with it.

For example, you may have a runny nose if exposed to pollen, develop a rash if you own a skin allergy, or feel sick if you eat something you’re allergic to.

See your GP if you or your kid might own had an allergic reaction to something. They can assist determine whether the symptoms are caused by an allergy or another condition.
