What are the symptoms of dehydration?

Patient's question:

Took a lot of medicine, the 5-day fluid replacement didn't work, my legs couldn't take it, the symptoms of the cold kept coming back, and then they got better. The doctor at this small clinic said that more medicine was taken, and the intravenous fluids became more and more, and dehydration occurred. What are the symptoms of dehydration?

Doctor's answer:

Hello, dehydration refers to a reduction in the body's fluid volume or an imbalance in the distribution of body fluids, leading to a decrease in effective circulation. Clinically, it may present with various systemic symptoms, such as poor skin elasticity, sunken eyes, nausea, vomiting, reduced urine output, fatigue, dizziness, and even coma. Correction of blood volume and electrolytes is usually required. Considering that it is not caused by dehydration, you may have a cold, headache, and need intravenous fluids. It is recommended that you do not take medication independently at small clinics and instead go to a formal hospital for blood tests and biochemical tests to confirm the diagnosis before treatment.
