What are the most common causes of dry mouth and sore throat?

Dry mouth, technically called xerostomia, can be caused by a number of different things. Dry mouth and sore throat symptoms are often related, as a dry mouth often causes a sore throat. Some of the main causes of dry mouth include dehydration, medications, nerve damage, infection, and a person's everyday lifestyle.

Dehydration can be a direct effect of excessive sweating, vomiting, diarrhea, burns, and blood loss. When too much fluid escapes from the body, the result is dehydration, which, in turn, will cause symptoms of dry mouth. The only way to combat dehydration is to try to rehydrate the body. Severe dehydration can only be cured through intravenous fluid.

Some people may experience a dry mouth and sore throat as a result of daily activity. People who smoke and drink heavily can experience dry mouth, as can people who regularly breathe through their mouths. These habits can be reversed by quitting smoking, cutting back on alcoholic beverages, and learning to breathe through your nose instead of your mouth.

Nerve damage can also cause mouth and throat problems. When the neck or head has been affected by an accident or surgery, a person may experience dry mouth on a regular basis. Anyone who believes they have nerve damage should seek medical attention immediately.

Various infections and diseases can also cause dry mouth and sore throat. Diabetes, HIV, Alzheimer's disease, anemia, stroke, arthritis, and many other conditions can cause dry mouth. When these diseases are properly controlled, this symptom often goes away. Those who have any of the aforementioned conditions should see a medical professional if dry mouth persists.

Sometimes dry mouth can be caused by medications. Medications for allergies, depression, anxiety, acne, and asthma, among others, can cause dry mouth and sore throat. In most cases, a dry mouth is a normal reaction to a variety of medications. If the dryness is not associated with a medication, it is important to seek medical attention.

The best way to combat a dry mouth is to drink water. While drinking plenty of water may not eliminate dry mouth caused by medications or illness, staying hydrated is the best way to eliminate temporary dryness. Soft drinks, alcohol, and other liquids may not hydrate the body as well as water, and these beverages should be avoided if a person feels dehydrated.
