Recognize signs of dehydration in your body. Dehydration is a condition where the body is lack of fluids. The result will be a decline in concentration, memory, and stamina. If the body needs more water, the nerve center in the brain is stimulated causing thirst. The thirst will grow stronger if the body’s need for water increases, encouraging someone to drink and satisfy his need for fluids.
Other mechanisms to control the amount of fluid in the body involves the pituitary gland at the base of the brain. If the body lacks water, the pituitary gland will secrete a substance into the bloodstream called antidiuretic hormone. Antidiuretic hormone stimulates the kidneys to retain water as much as possible.
If the body lacks water, the kidneys will hold water that is automatically transferred from the reserves in the cells into the blood stream to maintain blood volume and blood pressure, until fluid be replaced by the addition of fluid intake. If the body of excess water, the thirst is suppressed and the pituitary gland produces only slight antidiuretic hormone, which allows the kidneys to remove excess water through the urine.
Causes of dehydration
- The use of diuretics (drugs that cause the kidneys secrete large amounts of water and salt)
- Excessive Heat
- Reduced fluid intake due to various reasons.
Dehydration occurs when the body discharge greater than the intake. Lack of fluids usually causes calcium levels in the blood rise. Certain diseases such as diabetes mellitus, diabetes insipidus, and Addison’s disease can cause dehydration due to excessive fluid loss.
How to treat dehydration
For mild dehydration, which required only drink plain water. But if the loss of water and electrolytes, salt should also be given, particularly sodium and potassium. Drinks were bought and sold, has been formulated in such a way to replace the salts (electrolytes) lost after heavy exercise.
It can also be relieved by drinking fluids and eating a bit of salt during or after exercise. People who have heart or kidney problems, should first consult with their doctor about replacing fluids safely before exercising.
If the blood pressure is decreased resulting in shock, to overcome usually given a solution containing sodium chloride intravenously. Was initially given intravenous fluids quickly and then slowed in line with the improvement of the physical condition of the patient.
The underlying causes of dehydration are always addressed. For example, when a person is suffering from diarrhea, in addition to be given replacement fluids are also given drugs to treat or stop diarrhea. If the kidneys secrete too much water because there is a lack of antidiuretic hormone (as may occur in patients with diabetes insipidus), given the long-term treatment of antidiuretic hormone.
If the cause of the dehydration persists, monitoring the patient to ensure fluid intake sufficient to maintain hydration.
