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.
Nausea can be caused by various diseases of the upper GI tract-such as GERD, inflammation, an ulcer, as well as liver and gallbladder disease. Fatigue can be caused by a myriad of diseases-including anemia, kidney disease, dehydration, thyroid disease, as well as electrolyte abnormalities.
