Can a Sinus Infection Cause Dizziness and Nausea?

sinus infection cause dizziness and nausea

Sinusitis is the common term used to describe an infection of the sinuses. Your sinuses can become inflamed for a number of reasons. Inflamed sinuses can be caused by fungal, viral or bacterial infections. The four empty cavities which are referred to as the sinuses are located at the rear of the human skull. These four air pockets insulate and help to take the weight of the human skull. If the sinuses become blocked then they may become infected.  When the cavities fill up with fluid then acute sinusitis may occur. A prolonged sinus infection may result in chronic sinusitis. If any of this sounds like what you’re experiencing, you need to speak to an ENT doctor ASAP to learn more.

Symptoms of Sinus Infection

  • Fatigue
  • Bad breath
  • Facial pain and tenderness
  • Dental pain
  • Headaches
  • Night time coughing
  • Dizziness
  • Nausea

The Complications of Sinusitis

In general children seem to be more susceptible to sinusitis complications. If a child with sinusitis develops a swollen eyelid or cheekbone they must visit the physician. An infection of the sinuses is usually treated with a course of antibiotics. However, severe sinusitis may not respond to antibiotics and you might need other treatments such as Balloon Sinuplasty.

Can a Sinus Infection Cause Dizziness and Nausea

If the nasal passages are blocked and the sinuses are inflamed then the mucus cannot naturally drain away. When the tissue that lies close to the eyelids becomes infected it can cause light-headedness. Many people with a sinus infection find it difficult to maintain their balance. If the sinus infection affects the inner ear then dizziness often results.

How to Treat Dizziness Caused by a Sinus Infection?

In general the physician will recommend that you take a course of antibiotics. The antibiotic medicine will kill the infection. But the doctor may also recommend that you use prescribed decongestants to clear the blockage.

If you are feeling dizzy because you have an infection of the sinuses you should rest. Drink plenty of hot tea and soup. Sitting in a steam filled room will help to open the nasal passages and allow them to drain. Run a hot bath and sit in the steam filled room.

Sinusitis and Nausea

When the sinuses become blocked due to a sinus infection they fill up with mucus. The mucus cannot escape hence it becomes a breeding ground for viruses and bacteria. Hence alkaline mucus becomes acidic mucus. A build-up of acidic mucus can make you feel nauseous.

Overcoming Nausea Caused by a Sinus Infection

Nausea tends to be one of the most distressing symptoms of sinusitis. Avoid eating fatty foods. Eat small amounts of light carbohydrates. Try eating toast or crackers. Ginger helps to fight nausea. Eat a couple of gingersnaps or drink some ginger ale.

Finally, it is indeed true that a sinus infection can cause dizziness and nausea.

  5. I have had chronic sinus infections for the past 4 years. Recently i have been having symptoms of nausea, head aches, major pressure in my sinus, etc. the most debilitating of these is the nausea. last week i had my sinus x-rayed and today my doctor told me that i have a cyst in my sinus and referred me to an ENT specialist.
    is it likely that my nausea is caused by the cyst?

  8. I have sinus problems. Only, twice a year for at least a couple of weeks; I get dizzy and nausea and throw up, this happens twice a year when the weathwr changes. What can be done? When I get these symptoms I pump up on vitamin c. It seems to take care of it.

  9. I’m having drainage. I always believed it to be my sinuses. But, in the last week, I’ve been gagging at certain smells, and actually vomiting at times. Is that a symptom of a sinus infection?

  10. Hi, I have suffered with sinus problems for years.

    From blocked nasal passages to fluid build up in ears, headaches, facial pain, dizziness. Vomiting mucus when collecting or it apppears to go into stomach.

    All not very nice.

    I attend E.N.T. Recently received grommet insertion unnder local anesthetic to help ventilate inner ear, thus behind ear drum, where fluid collects and cant escape. The term called glue ear.

    This grommet will stay situated within ear for approiximately a year. When it will fall out itself and hole in ear drum should close naturally.

    By that time hopefully that would of dried out fluid from inner ear.

    I didnt find operation painful.

    Though in general when i have blocked nasal passage i use steam to open tubes and also kuse sterimar spray. It is sea water all sterile and natural product. Would be able to locate online to order.

    Apparently eating antitoxant food such as red grapes is good for your sinuses.
    Also consuming plenty fluids.

    I find damp wet weather causes more mucus secreetions and it can be chronic,. Thats when you receive a build up of fluids.

    They say it is wise in the winter to keep your mouth and nose covered with a scarf. Possibly temperature and weather changes may obviously cause issues with sinuses i assume.

    You can make up your own saline solution to flush out your nasal passage. Using warm water, rock or sea salt and bicarbonate of soda.

    Think it is half a pint of the water then one tablespoon salt and teaspoonful bicarbonate soda.
    Place some saline on a steaspoon and close one nostral and sniff the saline up other nostral.
    Then blow nose.

    This should help with infection and flush anything out of passage.

  11. I have had an infected sinus for three months,following a dental extraction.Dentist at first gave me antibiotics,but these fail to work. I have had ordinary sinus problems for years,and take citirizine.But I have never had anything this bad.The smell makes me constantly nauseated,and I vomit almost every morning. I really do not have a clue what to do.
    Two doctors at my Health Centre have given advice.The last one made the problem ten times worse! Does anyone have tried and tested ideas which actually work?
