Dehydration can occur when the body loses more fluid than it takes in, leading to an inadequate amount of water and other fluids to carry out normal bodily functions. While anyone can become dehydrated, certain groups, such as young children and older adults, are particularly vulnerable to its dangers. In young children, severe diarrhea and vomiting are the most common causes of dehydration. Due to natural aging processes, older adults have inherently lower water volume in their bodies and are prone to underlying health conditions and medication usage that heighten their vulnerability to dehydration. As a result, even minor illnesses like respiratory or bladder infections can lead to dehydration in older adults. Additionally, dehydration can affect individuals of any age if they do not consume enough water, especially during hot weather or when engaging in vigorous exercise. While mild to moderate dehydration can be effectively remedied by consuming more fluids, severe dehydration necessitates urgent medical intervention.
