Xerostomia means there is an abnormal lack of saliva. If you have Xerostomia you will have extreme dryness of the mouth. Drink plenty of water to avoid this type of problem. Clean water is becoming a priority for many countries because of river, lakes and ocean pollution. The weather also appears to be unstable or has a changing pattern in many regions causing water shortages as well.

This in turn causes droughts. Because fresh rainwater is difficult to obtain or costly in some countries, people turn to drinking alternative, shop bought fluids. This can lead to unhealthy kidneys because your kidneys need clean water to flush them and to keep your body functioning properly. Sugary drinks load your kidneys, and your body also changes the sugar into fat and stores it, causing weight gain.
