Dehydration
Water is vital in the body as it helps to ease and quicken some metabolic processes. Helping the salivary glands to secrete saliva is also one of the functions of water in the body. Hence, when a body lacks enough water, it also affects the salivary glands; this results in less secretion of saliva and brings about xerostomia. Although, there are different reasons the body could be dehydrated. It could be due to diseases such as fever, excess sweating, vomiting, diarrhea, blood loss, etc. All these diseases cause the body to lose water, leaving it dehydrated and leading to dry mouth. Note that it is not just about taking in water, it is about taking in the right quantity of water that will be enough to keep the body hydrated and not overhydrated as overhydration can cause other complications.
