Q: Can the heart be affected or damaged due to extreme dehydration? My husband suffered four days of diarrhoea and vomiting with no rehydration offered. The sickness was caused by intolerance to the anti-inflammatory drug, Volterol. The patient became very ill and developed tachycardia. Without treatment, this lead to arrhythmia, which was then responsible for three CVAs and blindness. Please advise.

A:Water is necessary for life. Extreme degree of dehydration can cause any complication such heart attack, kidney failure, stroke and clotting anywhere in the body and may produce fatal complications.
