Sinus infection and dizziness are commonly experienced together, as sinus infections can lead to ear infections that cause dizziness. In addition, some of the side effects of a sinus infection can make people feel lightheaded or dizzy, even though the balance system located in the ear is not actually affected. Treating sinus infections promptly can help reduce the risk of developing dizziness. It is important to be alert to the early warning signs of infections in the sinuses, including thick nasal discharge, a feeling of pressure or pain in the face, and a sensation of heaviness in the face.

The sinuses are a series of cavities in the skull. In healthy individuals, they hold pockets of air. In people with a sinus infection, they fill up with mucus and other fluids that build up as the body responds to the infection. Sinus infection and dizziness can be linked because many people with sinus infections develop fatigue and headaches, two problems that can make people feel unstable on their feet, especially when severe.

It is also possible for a sinus infection to lead to an ear infection and accompanying dizziness by clogging the eustachian tube. This structure normally drains fluid from the inner ear. When it is blocked, fluids build up in the ear, leading to infection and also disrupting the vestibular system, the system the body uses for balance. Sinus infection and dizziness are very common partners, as untreated sinusitis can lead to ear infection.

If people experience a sinus infection and dizziness and they are not already in treatment, they should see a doctor. The doctor can evaluate the patient and prescribe medications to kill the organisms causing the infection. Combined with rest and plenty of fluids, this should help the patient fight off the infection and get back to normal. People who experience recurrent or chronic sinus infections may want to explore preventative care, including allergy treatment to reduce inflammation in the sinuses and surgery to widen the drainage openings and prevent buildups of fluid.

Being aware of the connection between sinus infection and dizziness is important for people who work in jobs where dizziness could become a safety issue. These individuals may want to ask to be reassigned while they have active sinus infections to reduce the risks associated with their work. It is also advisable to refrain from vigorous exercise, as people who are feeling dizzy may fall and injure themselves.
