What are the symptoms of dehydration?

Patient's question:

Took a lot of medicine, lost 5 days of fluid without effect, legs couldn't take it, cold symptoms recurred, and then got better. The doctor at this small clinic said that more medicine was taken, and more intravenous fluids were given, and dehydration occurred. What are the symptoms of dehydration?

Doctor's answer:

Hello, dehydration refers to a decrease in the body's fluid volume or an imbalance in the distribution of body fluids, leading to reduced effective circulation. Clinically, it may present with various systemic symptoms, such as poor skin elasticity, sunken eyes, nausea, vomiting, decreased urine output, fatigue, dizziness, and even coma. Typically, it is necessary to correct blood volume and electrolytes. Considering that it is not caused by dehydration, you may have a cold, headache, and receive 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.
