nedvességhiány

Nedvességhiány, also known as dehydration, is a condition that occurs when the body loses more fluid than it takes in. This imbalance can disrupt normal bodily functions. The primary cause of dehydration is insufficient fluid intake, but it can also be exacerbated by excessive fluid loss through sweating, vomiting, or diarrhea. Certain medical conditions and medications can also contribute to dehydration.

Symptoms of dehydration vary depending on its severity. Mild dehydration may present with thirst, dry mouth, and reduced urine output. As dehydration progresses, symptoms can include fatigue, dizziness, headache, and decreased skin turgor. Severe dehydration is a medical emergency and can lead to confusion, rapid heartbeat, low blood pressure, and in extreme cases, shock and organ failure.

Children and older adults are particularly susceptible to dehydration due to physiological differences. Infants have a higher proportion of body water, making them more vulnerable to rapid fluid loss. Elderly individuals may experience a diminished sense of thirst or have conditions that impair fluid regulation.

Prevention is key to managing dehydration. Ensuring adequate fluid intake throughout the day, especially during hot weather or physical activity, is crucial. Monitoring urine color can be a useful indicator; pale yellow urine generally signifies adequate hydration. Treatment for dehydration involves replenishing lost fluids and electrolytes. For mild cases, oral rehydration solutions are often effective. Severe dehydration typically requires intravenous fluid administration in a healthcare setting.
