Dehydration
Everybody needs water and other fluids for the body to function normally. However, people lose body fluids through sweat and urine. If the fluid intake is less than the fluid the body loses, dehydration will ensue. People who sweat profusely, including those who work outside, athletes, and those who exercise, lose more body fluids. Thus, they need to consume more fluids to prevent dehydration.
Losing more water occurs when a person has a fever. Severe diarrhea likewise makes a person lose more body fluids. Vomiting is another cause. A person with diabetes urinates more often. Some people do not realize that they are already thirsty, while others are too busy to remember that they should drink water. If a person has a stomachache, drinking water might be difficult as it increases the pain. Moreover, if a person has mouth sores or sore throat, they might forego drinking water to lessen the pain.
But there are instances where dehydration is a sign of something that needs medical intervention. For example, a person with a high level of inorganic arsenic in their system can cause gastrointestinal disorders that cause diarrhea, abdominal pain, and vomiting, which could quickly lead to shock and dehydration.
