Nasal congestion, stuffiness, or obstruction to nasal breathing is one of man's oldest and most common complaints. While it may be a mere nuisance to some persons, to others it is a source of considerable discomfort, and it detracts from the quality of their lives.

Medical writers have classified the causes of nasal obstruction into four categories, recognizing that overlap exists between these categories and that it is not unusual for a patient to have more than one factor involved in his particular case.

Vasomotor Rhinitis

''Rhinitis" means inflammation of the nose and nasal membranes. "Vasomotor" means blood vessel forces. The membranes of the nose have an abundant supply of arteries, veins, and capillaries, which have a great capacity for both expansion and constriction. Normally these blood vessels are in a half-constricted, half-open state. But when a person exercises vigorously, his/her hormones of stimulation (i.e., adrenaline) increase. The adrenaline causes constriction or squeezing of the nasal membranes so that the air passages open up and the person breathes more freely.

The opposite takes place when an allergic attack or a ''cold'' develops: The blood vessels expand, the membranes become congested (full of excess blood), and the nose becomes stuffy, or blocked.

In addition to allergies and infections, other events can also cause nasal blood vessels to expand, leading to vasomotor rhinitis. These include psychological stress, inadequate thyroid function, pregnancy, certain anti-high blood pressure drugs, and overuse or prolonged use of decongesting nasal sprays and irritants such as perfumes and tobacco smoke.

In the early stages of each of these disorders, the nasal stuffiness is temporary and reversible. That is, it will improve if the primary cause is corrected. However, if the condition persists for a long enough period, the blood vessels lose their capacity to constrict. They become somewhat like varicose veins. They fill up when the patient lies down and when he/she lies on one side, the lower side becomes congested. The congestion often interferes with sleep. So it is helpful for stuffy patients to sleep with the head of the bed elevated two to four inches accomplish this by placing a brick or two under each castor of the bedposts at the head of the bed. Surgery my offer dramatic and long time relief.

Summary

Stuffy nose is one symptom caused by a remarkable array of different disorders, and the physician with special interest in nasal disorders will offer treatments based on the specific causes.
