Sinusitis is a respiratory infection. Sometimes an allergic reaction could also lead to sinusitis. An infection in sinus causes the membrane encompassing it to swell. The swollen sinuses as a result tend to squeeze, thereby exerting pressure on the trapped mucus. This condition gives rise to symptoms such as headache, fever, post-nasal drip and even nausea.
Sinus and nausea are although not related to each other but infection due to sinuses can give rise to symptoms of nausea. Sinus is associated with the drainage of mucus. This mucus tends to travel down to the stomach through the throat instead of coming out from nostrils. Excess of mucus in the stomach can give a feeling of nausea.
There are some people who are more susceptible and prone to sinus infection and nausea than others. People who are allergic and asthmatic experience this problem quite often. Also included in this category are people who are swimmers or regular flyers. A change in the air pressure leads to sinus and the associated symptoms such as nausea. Most of the symptoms of sinus are usually common problems and can be a consequence of certain other ailments as well. For example, a stomach upset or headache can result from stress and anxiety. In some cases, migraine headaches can also cause nausea.To ascertain the exact cause of nausea, one must undergo a through medical examination. Chronic sinusitis sometimes goes unnoticed and can only be confirmed through image testing. Once diagnosed, it is not very difficult to treat this problem. Treatment of sinusitis is usually a blend of administration of antibiotics, antihistamines, decongestants and corticosteroids. However, if sinus infection is caused due to bone spur or polyps, then it would probably require a surgery.
