While our water in civilized countries is regulated, we still have to protect ourselves.   Contaminated water supplies are responsible for stomach problems, from small upsets to severe disorders. But, making sure water is filtered within the home as an added safety measure can prevent that.  A few contaminants to watch out for are lead, mercury, copper, arsenic and cadmium.  These can cause diarrhoea, nausea, vomiting and other stomach problems.

Drinking water can be of help in several of those cases, and even aid in their prevention.  Diarrhoea, watery stool, can cause severe dehydration, so it is important to maintain body fluid if suffering from that.  But, constipation can also use water to help break down the dry stool.

Water is a necessary factor to make sure our digestive system works properly.  Drinking water at mealtime aids in the digestive process, as it helps move the food through the system.
