Can food allergies cause post nasal drip?

 



Are you struggling to find a post nasal drip cure or have you tried many different post nasal drip “remedies” that never seemed to work? Accurately diagnosing and treating post nasal drip is a challenge for many doctors and patients. A good analogy is like trying to put a together jig saw puzzle. Your doctor has to know all of the pieces and how they fit together. This educational section will help empower you to find the right treatment for your post nasal drip.

Post Nasal Drip

can be described (in part) as the feeling that something is draining in the back of the throat. Mucus glands in the nose and throat continuously produce mucus throughout the day and night. Normally, people are not aware of the act of swallowing the mucus/phlegm. However, certain conditions can cause patients to become aware of this sensation.

The feeling of PND may be do to actual mucus or phlegm in the throat or only the perception of it. One of the most common but rarely diagnosed causes of post-nasal drip occurs when the nerve tissue of the throat and voice box becomes damaged- typically by an Upper Respiratory Infection (common cold). This will be discussed below in the section: Laryngeal Sensory Neuropathy (LSN). For these patients, there is usually no actual drainage, mucus, or phlegm. The main symptoms of LSN are throat clearing and coughing that do not respond to other post nasal drip treatments.

PND associated with allergies:

Medications used to treat LSN help heal the nerve tissue in the throat and voicebox Amitriptyline (Elavil)Amitriptyline is a medication that was originally used to treat depression. However, it is no longer used for this purpose because of the of newer generation anti-depressants. Currently it is used primarily to treat headaches and neuropathies (pain and tingling caused by nerve damage). Since LSN is caused by nerve damage to the throat and airway, amitriptyline is able to heal the nerve damage.

Main side effects of Amitriptyline include dry mouth and sedation. Other side effects involving the heart, eyes, and other organs can also occur.

Modern Immunology treats deadly Diseases?

Image
  Modern immunology has gradually developed into an independent subject with its own theoretical system and special research methods. It provides some new means for biological research. Immunology is a bio medical science that studies the immune response of an organism against the original substance and its methods. Immune response is not only the response of the organism to antigen stimulation, but also a biological process of recognizing and eliminating antigen substances. The emergence of monoclonal antibody technology has become a major breakthrough in the field of immunology. Monoclonal antibodies can be used to detect the surface molecules of various immune cells and other tissues, which is of great significance for the isolation, identification and classification of immune cells and the study of the structure and function of various membrane surface molecules.  The theory of immunology has been greatly enriched and improved. At the same time, many new research d...

Can Allergies curable ?

Allergies are our body’s reaction to a usually harmless substance such as pollen, molds, animal dander, latex, particular foods and insect bites.  Allergy symptoms  can be range from mild – rash or hives, itchiness, runny nose, watery/red eyes – to life risk.

These diseases are allergic rhinitis, food allergies, atopic eczema, allergic respiratory disorder, and hypersensitivity reaction. Symptoms could embody red eyes, Associate in Nursing unquiet rash, sneezing, coughing, a fluid nose, shortness of breath, or swelling. Food intolerances and sickness are separate conditions .

Can Allergies be Genetics?

  Children can inherit the tendency to be allergic . The maternal allergies are more likely than paternal allergies to lead to the child inheriting allergies . “People inherit the ability to be allergic, but they don’t inherit what they’re allergic same family, there can be people who are allergic to cats and other people who are allergic to peanuts and other may allergic to something else. The effects of the environment on developing allergies are often mediated by  epigenetic modifications, which are changes to DNA, but not to genes themselves. Allergies, also known as anaphylaxis, occur when an allergen causes an adverse reaction to the body's immune system. Allergens when combined with antibodies will cause harm to human health . Gradually, the body will initiate some allergic diseases in children.  This is an allergic condition that arises when the weather changes suddenly or the body the patient is exposed to too hot or too cold climates. When allergic t...
