Understanding the Causes of Nasal & Sinus Infections

Sinusitis is a medical condition in which infections develop in the mucosal cells of the nasal cavities and sinuses. This condition has several causes. In rare cases, it may result in complications.

Sinusitis

• Sinusitis inflames the sinuses. It often follows a case of the common cold.

Causes

• Mucous membranes of the nose and sinuses that are moist and congested can become infected, because they provide an environment for bacteria and other infectious agents to grow.

Symptoms

• People with sinusitis may develop nasal discharge and congestion, fever and headaches. Fatigue, sore throat and coughing can also occur with this condition.

Complications

• In rare instances, sinusitis patients may develop meningitis, bone infections or skin infections near the eyes.

Treatment

• Doctors may prescribe antibiotics for chronic cases of sinusitis, but many cases clear up on their own with plenty of fluids and over-the-counter pain relievers.
