Viruses and bacteria lead the list of factors that commonly cause sore throat and nausea. Environmental allergens, disease, and medication can also make a person nauseated and give him or her a sore throat either together or separately. Patients undergoing cancer treatments often complain that chemotherapy can induce sore throat and nausea, while radiation for cancer generally produces nausea. These symptoms typically last between 24 hours and three days.

A sore throat can emerge at the onslaught of a common cold virus as a raw, achy sensation in the lining of the throat, most noticeable during swallowing. Severe cases can make it difficult to swallow and frequently occur with phlegm. In addition to the common cold, croup, flu, and mononucleosis are other specific viruses most often responsible for sore throats. Viruses that cause the childhood diseases of chickenpox and measles can also produce raw and achy throats.


In 10 percent to 50 percent of bacteria-based sore throat and nausea cases, streptococcus bacteria appears to be the blame, followed by the arcanobacterium haemolyticum bacteria, known for causing rash. Other specific bacterial causes include tonsillitis and diphtheria. These airborne bacteria, along with the previously identified airborne viruses, easily spread from one sick person to another by invading the surrounding air as a result of sneezes and coughing fits by the afflicted person. Then, the contagions are inhaled into the respiratory system. Touching mucous and germs on shared towels, door handles, and eating utensils can also transmit the microbes that cause sore throats.

For nausea, which is the condition of having an unsettled stomach that attempts to eject its contents, pneumonia and bronchitis are the leading bacterial and viral causes. Often, gastritis, caused by E.coli bacteria, salmonella and listeria in food or water, is the culprit for nausea. Inflammation of the stomach lining, formally called gastritis, can also occur from stomach flu.

Diseases like pancreatis, hepatitis and cancer frequently induce nausea. Often, cancer tumors lining the stomach are not detected until the nauseous patient begins vomiting regularly and then goes to the doctor for explanation and diagnosis. Mundane triggers like bad smell, unpleasant food, and worry can also lead to nausea; so too can morning sickness and pregnancy.

When sore throat and nausea conditions last more than 72 hours, victims generally elect to see a physician. Anti-nausea prescription drugs like promethazine or droperidol are often prescribed. In the case of a sore throat, it is common for doctors to perform strep tests and prescribe antibiotics or penicillin.

@ysmina-- If you have a sore throat and no fever, it might be allergies.

I'm allergic to all nuts. If I eat anything with nuts in it, I get a rash, a swollen, sore throat and nausea.

If you think you're allergic, go to the ER, especially if you have trouble breathing. Allergies can cause anaphylaxis which can cause swelling in your throat and prevent you from breathing. It's dangerous.

@ysmina-- You might have these symptoms at the same time, but this doesn't mean that the cause is the same.

Nausea and sore throat can be caused by a cold (due to a bacterial infection). There are bacteria that cause upper respiratory infections and settle in the throat. Sore throat is common during such an infection. Infections also tend to cause upset stomach and can cause nausea.

The causes could be different though. For example, you might have a sore throat due to an infection and nausea from bad food. You should see a doctor if you don't feel better to find out what's wrong for sure.

I've had a sore throat for the past few days and now I'm also nauseated. I've never experienced these two symptoms before. I usually get a sore throat when I have a cold and I get nausea when I have an upset stomach.
