The immediate treatment for cholera is to give glucose-saline drip or ORS. Explain with respect to the functioning of kidneys.

Explanation

When the person is affected by cholera, he suffers from vomiting and watery bowels. In this condition, the intestine is unable to absorb water into the blood. Therefore, the kidneys reabsorb almost all the water from the renal tubule. Along with water, urea also is reabsorbed. This may lead to the accumulation of high quantity of urea in his body. This condition is called uraemia. High quantity of urea in the body may lead to poisoning which becomes fatal. Therefore, the water should be replenished in the blood to decrease the quantity of water being reabsorbed in the kidneys.
