Signs and Symptoms of Dehydration

Aside from the common symptoms like intense thirst or sweating too much, here are some of the mild and severe symptoms of dehydration:

Infants are more vulnerable to dehydration, that's why immediate attention must be given to them especially if you see these symptoms: 

• Sunken soft spot (fontanelle) on their head
• Few or no tears when they cry
• Dry mouth
• Few wet diapers
• Drowsiness
• Fast breathing

Chronic dehydration may affect your organs and lead to kidney stones, cholesterol problems, constipation, and liver, joint, and muscle damage. 
Whether it is mild, moderate, or severe dehydration, the lost liquids in your body must be immediately replaced. If you start to develop severe diarrhea with or without vomiting, fever, moderate diarrhea for 24 hours, bloody stool, or you can't drink any liquids, you must get professional treatment as soon as possible.
What Causes Dehydration?There are various reasons for dehydration like intense physical activity, which makes you lose so much water – fat and calories are counted as well – so proper hydration is necessary. Other causes of dehydration include:

• Diarrhea. It prevents your intestinal tract from absorbing water from the foods that you eat, which makes it the most common cause of dehydration. 
• Vomiting. Common causes include foodborne illnesses, nausea, and alcohol poisoning.
• Sweating. Vigorous sweating may happen due to various reasons like fever and engaging in intense physical activity. Profuse sweating can also occur when you are working in a hot condition.
• Diabetes. Aside from having high blood sugar levels, some medications for diabetes like diuretics may cause diabetics to frequently urinate. 
• Frequent urination. It can be cause by alcohol and certain drugs like antihistamines, blood pressure medications, and antipsychotics.
