Overview on dehydration
When your body loses or uses more fluid than it takes in, it becomes dehydrated and is unable to operate normally due to a shortage of water and other fluids. Dehydration will occur if lost fluids are not replaced.
Dehydration can affect anybody, but it can be particularly harmful to small children and elderly people.
Severe diarrhea and vomiting are the most prevalent causes of dehydration in young children. Elderly people may be more susceptible to dehydration due to medical issues or drug side effects, as well as having naturally lower body water levels.
This implies that dehydration in older persons can arise from mild ailments as well, such as bladder or lung infections.
Any age group can experience dehydration as well if they don't drink enough water in hot weather, particularly if they are engaging in strenuous exercise.
Drinking additional fluids can usually help reverse mild to moderate dehydration, but severe dehydration requires medical attention right away.
