What is the connection between sinus infection and nausea?

Sinus infection and nausea may seem unrelated, but an infection can cause many symptoms, including nausea. The mucus that drains from the sinuses is more likely to run down the back of the throat and into the stomach rather than through the nasal passages. Excessive levels of mucus in the stomach can cause nausea.

Sinusitis, or a sinus infection, is an inflammation of the paranasal sinuses. As the membranes around the breasts swell, the breasts become compressed. Pressure from swollen tissue and trapped mucus can cause a wide range of symptoms, including headache, postnasal drip, fever, and nausea.

Most often, sinusitis is caused by a respiratory infection or an allergic reaction. Any condition that causes inflammation of the sinus membranes can cause a sinus infection. When the sinuses become swollen, the mucus cannot drain properly and becomes a breeding ground for bacteria, viruses, and fungi.

Some people are naturally more prone to sinus infection and nausea than other people. Allergy sufferers and asthmatics are likely to experience regular swelling. People who have growths like nasal polyps have less space available for swelling, and less swelling is needed to block the sinuses. A deviated cleft palate septum can cause a similar vulnerability to sinus infection and nausea. Swimmers are also more vulnerable, as are frequent flyers who regularly experience changes in air pressure.

Many of the symptoms of a sinus infection are quite general, and what appears to be a sinus infection and nausea could be another condition or conditions. Tension and anxiety, for example, can cause an upset stomach and headache. Migraine headaches can be intense and can also cause nausea. Chronic sinusitis, which involves regular or long-term inflammation, is especially difficult to diagnose and may require imaging tests to confirm.

After a sinus infection and nausea have been diagnosed, treating them will usually require a visit to the doctor. The body has a natural ability to fight infection, but if the infection is severe enough to cause nausea, it is recommended that you consult a medical professional. Depending on symptoms and severity, medical treatments are likely to include a combination of antibiotics, antihistamines, decongestants, and corticosteroids. Cases of chronic sinus infection caused by bone spurs or polyps may require surgery.

For those more vulnerable to sinus infection and nausea, steps can be taken to limit risk. Smoking not only irritates the sinus membrane but also reduces the body's ability to fight infection. When possible, known allergens should be avoided. Humidifiers can be helpful, and inhaling steam several times a day can also help keep swelling down.
