What are the symptoms of dehydration?

Water is the source of life and is essential for all objects in the world. There is even a saying that: you can go without food for seven days, but you cannot go without water for three days, which further illustrates the importance of water. Dehydration in the body can cause yellow urine, dry stools, etc. Do you want to know in detail what symptoms the human body will have if it is dehydrated?

1. Dry mouth and swollen tongue

The first sign that your body is dehydrated is thirst. Dehydration can cause dry mouth and slight swelling of the tongue, so drink water on time in summer.

2. Dark yellow urine

As blood pressure drops and body tissues lose water, a dehydrated person's kidneys concentrate urine or even stop producing urine. As the urine concentration increases, its color will gradually darken, and in severe cases it will become dark yellow or even amber.

3. Constipation

Constipation occurs when the intestines absorb too much water. Once the body is dehydrated, the intestines will absorb more water to replenish body fluids, resulting in dry stools.

4. Lack of skin elasticity

Dehydration reduces skin elasticity. Doctors use the "pinch test" to quickly check skin elasticity and determine whether a patient is dehydrated.

5. Dizziness

In addition to decreased blood flow and blood pressure, dehydration can also cause dizziness and lightheadedness. One of the key signs is sudden dizziness when standing up quickly.

6. Fatigue

Long-term dehydration can easily lead to a decrease in blood flow and blood pressure, and a subsequent decrease in blood oxygen content. Without adequate oxygen, muscle and nerve function weakens, making fatigue more likely.

7. No tears

If you cry loudly but no tears come out, then you are definitely dehydrated.

8. Palpitations

The heart, like other muscles in the body, can suffer from palpitations due to reduced blood flow and electrolyte changes caused by dehydration.

9. Muscle spasms

Long-term dehydration can cause electrolyte imbalance in the body, leading to persistent muscle cramps during or after exercise.
