What Causes Sinus Infections

Sinus infections are bacterial infections that occur due to a blockage in the sinuses. The build up of mucus in the sinuses can happen due to a variety of different conditions. Common colds and other virus infections are common illnesses that lead to congestion, however, environmental factors and genetics can also cause congestion and lead to a sinus infection. When stagnant mucus sits in the sinuses with nowhere to go, it becomes a breeding ground for bacteria and causes an infection.

Not every case of congestion will lead to a sinus infection. Signs that your symptoms are progressing into a sinus infection include symptoms worsening instead of getting better over time, a fever, facial pain or pressure behind the eyes and developing a fever.
