Patients with severe dehydration should be assessed for shock (tachycardia, low blood pressure and delayed capillary refill time etc.). Electrolyte disorders may cause tachypnoea, muscle cramps or weakness, cardiac arrhythmia (irregular heart rate, palpitation), confusion and/or seizures.
Full Answer
Other dehydration causes include: Diarrhea, vomiting. Severe, acute diarrhea — that is, diarrhea that comes on suddenly and violently — can cause a tremendous loss of water and electrolytes in a short amount of time. If you have vomiting along with diarrhea, you lose even more fluids and minerals. Fever.

Moderate to severe dehydration can cause tiredness, confusion, muscle cramping, poor kidney function, little-to-no urine production, and fast heart rate. Severe dehydration can lead to shock, weak pulse, bluish skin, very low blood pressure, lack of urine production, and in extreme cases, death.
Many diseases -- such as diabetes, cystic fibrosis, and kidney disease -- increase dehydration risk and the need for fluids. For example, people with uncontrolled diabetes urinate frequently. Some medications can also cause a person to urinate or sweat more than normal.
