Dehydration occurs when there is enough water to replace what is lost throughout the day. The system literally dries out. Sometimes dehydration occurs for simple reasons: you do not drink enough because you are sick or busy, or because there is no drinking water, when you travel, hiking, or camping.
Other causes of dehydration are:
Diarrhea, vomiting. Severe acute diarrhea - that is, diarrhea that is suddenly and violently - can cause a huge loss of water and electrolytes in a short period of time. If you have vomiting and diarrhea, you lose more fluids and minerals. Children and infants are particularly at risk.
Fever. Generally, the higher the fever, the more dehydrated you become. If you have a fever of more than diarrhea and vomiting, you lose more fluid.
Excessive sweating. You lose water when you sweat. If you do intense physical activity and do not replace the fluids along the way, you can dry. Hot and humid climate increases the amount of sweat and the amount of fluid you lose. But you can also dry in winter, if not replace lost fluids. Preadolescents and adolescents participating in sports may be particularly sensitive, as well as their weight, which is generally lower than in adults, and therefore can not be experienced enough to know the signs of dehydration.
Increased urination. This is most often the result of uncontrolled diabetes mellitus or undiagnosed, a disease that affects the way your body uses sugar. This type of diabetes often causes increased thirst and frequent urination. Another type of diabetes, diabetes insipidus, is also characterized by excessive thirst and urination, but in this case the cause is a hormonal disorder that causes the kidneys can not conserve water. Certain medications - diuretics, antihistamines, antihypertensives, and some psychiatric drugs - and alcohol can also lead to dehydration, generally because they make you urinate or sweat more than normal.
