Symptoms of dehydration

summary

Dehydration refers to the human body due to pathological changes, consumption of a lot of water, and can not immediately supplement, resulting in metabolic disorders of a symptom, serious will cause collapse, and even life-threatening, need to rely on fluid infusion. According to the changes of blood sodium or osmotic pressure, dehydration can be divided into hypotonic dehydration, that is, the decrease of extracellular fluid combined with hyponatremia; Hyperosmotic dehydration is the decrease of extracellular fluid and hypernatremia; Isoosmotic dehydration means that the extracellular fluid is decreased and the blood sodium is normal. Symptoms of dehydration? Let's talk about it

Symptoms of dehydration

Dry mouth and swollen tongue: the first sign of water shortage is thirst. Dehydration can cause dry mouth and slight swelling of the tongue, so drink water in time in summer. Dizziness: in addition to decreased blood flow and blood pressure, dehydration can also cause dizziness. One of the key signals is to stand up quickly, suddenly dizzy.

Urine dark yellow: with the decrease of blood pressure and lack of water in body tissues, dehydrated kidney will concentrate urine and even prevent the production of urine. With the increase of urine concentration, the color of urine will gradually deepen, and in severe cases, it will be dark yellow or even amber.

Constipation: when the intestinal absorption of excessive water, constipation will occur. Once the body is short of water, the intestines will absorb more water to supplement body fluids, leading to dry stools. Lack of skin elasticity: dehydration reduces skin elasticity. Doctors can quickly check the skin elasticity through "squeezing test" to judge whether the patient is dehydrated.

matters needing attention

The key point of rehydration is 24 hours on the first day, severe dehydration, hypovolemic shock and severe acidosis. First of all, we need to expand the volume and correct the acid, and then continue to supplement the accumulated loss, abnormal and continuous physiological loss. After blood circulation and renal function are restored, the body can regulate itself. Pay attention to supplement potassium in the process of dehydration.
