Also called rhinorrhea, is a very common medical disorder that occurs when the nasal tissues are congested and the excess fluid runs either at the back of the throat or out of the nose. Post-nasal drip can be caused by the common cold, allergies to dust, smoking, or pet dander. Even spicy foods can sometimes cause post-nasal drip.
Treatment options depend on the nature of an individual's post-nasal drip and its cause. Antibiotics may be prescribed if the PND is the result of bacterial sinusitis. [ 8 ] In cases where PND is caused by allergic rhinitis or irritant rhinitis, avoidance of allergens or irritating factors such as dander, cigarette smoke, and cleaning supplies ...

In chronic nasal and sinus disease of cats, FHV-1 may play more of an initiating role than an ongoing cause. Infection at an early age may permanently damage nasal and sinus tissue, causing a disruption of ciliary clearance of mucus and bacteria, and predispose these cats to chronic bacterial infections.

Treatment includes withdrawal of nasal drops, short courses of systemic steroid therapy and in some cases, surgical reduction of turbinates, if they have become hypertrophied. Rhinitis of pregnancy Pregnant women may develop persistent rhinitis due to hormonal changes. Nasal mucous become edematous and block the airway.
One of the purposes of nasal mucus is to warm inhaled air to body temperature as it enters the body; this requires the nasal cavities to be constantly coated with liquid mucus. In cold weather the mucus lining nasal passages tends to dry out, so that mucous membranes must work harder, producing more mucus to keep the cavity lined.
They are connected to the nasal passage through some small openings called ostia. While the ostia can become clogged, clogged ostia is not at all the same as a "stuffy nose" or "nasal congestion". Nasal congestion is mostly a mechanical constriction of the nasal airway, caused by swelling in the turbinates/concha.
