What happen to us if you had no kidney?

If a person has no kidneys, they would be unable to survive without medical intervention. The kidneys are essential organs that perform a variety of important functions in the body, including:

1. Excretion of Waste Products: The kidneys filter waste products, such as urea, creatinine, and uric acid, from the blood and eliminate them through urine. Without kidneys, these waste products would accumulate in the body and reach toxic levels.

2. Regulation of Fluid Balance: The kidneys help regulate the balance of fluids in the body by controlling the amount of water excreted in urine. Without kidneys, the body would retain too much or too little water, leading to imbalances that can disrupt various bodily functions.

3. Regulation of Electrolytes: The kidneys play a vital role in maintaining the proper balance of electrolytes, such as sodium, potassium, chloride, and bicarbonate, in the bloodstream. Without kidneys, these electrolyte levels could become abnormal, leading to muscle weakness, heart problems, and other complications.

4. Regulation of Blood Pressure: The kidneys contribute to the regulation of blood pressure by controlling the fluid and electrolyte balance. Without kidneys, blood pressure could become too high or too low, leading to cardiovascular problems.

5. Production of Erythropoietin: The kidneys produce a hormone called erythropoietin, which stimulates the bone marrow to produce red blood cells. Without kidneys, the production of red blood cells would decrease, leading to anemia.

6. Regulation of Acid-Base Balance: The kidneys help maintain the proper acid-base balance in the body by controlling the excretion of hydrogen ions and bicarbonate ions. Without kidneys, the body's pH level could become too acidic or too alkaline, causing various health issues.

7. Vitamin D Activation: The kidneys convert vitamin D into its active form, which is crucial for the absorption of calcium and bone health. Without kidneys, this activation process would be compromised, leading to potential bone problems.

Therefore, the absence of kidneys would have severe consequences on multiple vital functions of the body, leading to life-threatening health conditions. In such cases, medical interventions such as kidney transplantation or dialysis become necessary to replace the functions of the lost kidneys and maintain the individual's survival.
