Dry mouth and fever are two symptoms that can arise in association with some fairly serious conditions. When the two develop after you have eaten, though, the cause is often much easier to pinpoint. This makes it easier for a doctor to verify the cause of your symptoms and determine the best course of treatment. But the more you understand about what is happening in your body before you visit a doctor, the better able you will be to take care of yourself.

Dry mouth has a unique feel, and an easy description: You may feel thirsty or feel unable to produce saliva to lubricate your mouth. The inside of your mouth and your tongue may also feel rough and sticky. Fever, on the other hand, is a common symptom typified by a warm body temperature. This is often identifiable on the forehead, but using a thermometer can verify a raised temperature.

Other Symptoms

You might experience excessive thirst with these conditions. You might experience an upset stomach, nausea and vomiting. Other possible symptoms can include blurred vision and drowsiness, according to Medline Plus.

Possible Causes

Dehydration is a common condition that can cause dry mouth and fever, but according to Medline Plus you can also experience these symptoms by taking medications, particularly a motion sickness medication called scopolamine. You may also experience dry mouth and fever due to some food poisoning.


The only way to curb the effects of medications is to reduce the dosage or stop taking the medication. Food poisoning often has to run its course, but consulting a doctor may give you other treatments and medication to expedite healing. Fight dehydration with slow sips of water. Avoid chugging water, which can make your body sick from the sudden swing.


If you experience unexplained symptoms in association with your dry mouth and fever, or if you are unable to identify the cause of your symptoms, it is important that you seek medical attention right away. You could be suffering from a serious condition, particularly in the case of food-borne illness, and early detection and treatment can play a huge role in how quickly you recover.
