Sinus inflammation goes by the medical term sinusitis. This condition occurs when irritants cause swelling of the tissues that line your sinus cavities. Cold viruses, as well as a host of other conditions, commonly cause sinusitis. Zinc may help treat cold symptoms, including sinus problems, although more research is necessary to confirm the potential health benefits of using zinc to combat the cold virus.
Zinc
The trace mineral zinc exists in every cell in your body. This important mineral plays an essential role in protecting the health of your immune system, as well as supporting growth, vision and smell. Zinc acts as an antioxidant, helping to protect your body from free radical damage. Consuming about 10 mg zinc per day provides a sufficient amount for most adults, although some people, especially alcoholics, elderly individuals and patients with Crohn's disease, may experience zinc deficiencies. Although not all studies agree, some research indicates that zinc may help reduce cold symptoms, according to the University of Maryland Medical Center.
Sinus Problems
Sinus inflammation commonly occurs with the common cold. The cold virus irritates mucous membranes, leading to nasal congestion and discharge. Other symptoms of sinusitis include toothache, cough, sore throat, bad breath, loss of smell, fever and fatigue. You may experience pressure and pain behind your cheeks, eyes, forehead and nose. Besides the common cold, other factors can increase your risk of sinusitis. These include frequent swimming, nasal polyps and asthma. Current research does not support the use of zinc to treat sinus problems associated with these causes.
Treatment
Zinc comes in a variety of forms, including nasal sprays, syrups, lozenges and pills. Zinc may help prevent sinus problems from colds by keeping the rhinovirus from multiplying, according to Mayo Clinic internist Brent A. Bauer. Rhinovirus is the type of virus that causes most colds. Zinc may also provide protection by keeping the virus from attaching to the mucous membranes in your nose and throat.
Precautions
Talk to your doctor before taking zinc to treat sinus problems. Chronic sinus infections may indicate the presence of an underlying health condition. Avoid taking more than the recommended dose of zinc. This mineral can cause nausea. Zinc can interact with certain medications, including blood pressure medications and antibiotics.
