One go to the other. What is the difference between heat stroke and heat exhaustion they are on the same track. This often occurs when one starts out behind in their overall body fluid balance. But it could occur if anyone at any time with the right circumstances. Generally one has spent time in the hot sun or in a very hot environment while not keeping up with their water intake. Many times already starting out partially dehydrated. What happens next is a continuum of symptoms. It might start with fatigue, headache, weakness, dizziness, or even fainting. Other symptoms could include nausea and vomiting infusion, excessive thirst, muscle cramping and aching, a slow or weakening heartbeat. The patient may also become drenched in sweat. If the above patient is untreated and the symptoms are unrecognized the progression of the symptoms would go from what's described above (heat exhaustion) to what is known as a heat stroke. So to simply put it a heat stroke would generally be a continuation and worsening of the symptoms described above. By the time a person has a heat stroke they have often gone from profusely sweating to not sweating it all, from a slow and weak heart rate to a very rapid heart rate, from a normal temperature to a very elevated temperature such as 104 -106°F. The patient is generally going to be very confused as they can also be with heat exhaustion. The patient may also have what we refer to as delirium to go along with their confusion and many times though even have a seizure. This is clearly a medical emergency and no time should be wasted in getting that person to the emergency room.
