Here's why:
* One kidney removed: If one kidney is removed or damaged, the remaining kidney can increase in size and function to compensate for the loss. This is a remarkable adaptation that allows the body to maintain normal kidney function despite the loss of half its filtering capacity.
* Increased workload: Even if both kidneys are present, they can undergo hypertrophy in response to increased workload, such as in cases of high blood pressure or diabetes.
Other organs capable of hypertrophy:
While the kidney is a classic example, other organs can also undergo hypertrophy, including:
* Heart: In response to high blood pressure or heart valve defects, the heart muscle can thicken to pump blood more effectively.
* Liver: The liver can enlarge to compensate for damage or increased workload.
* Uterus: The uterus undergoes significant hypertrophy during pregnancy to accommodate the growing fetus.
Important Note: Compensatory hypertrophy is not always a good thing. While it can be a beneficial adaptation, it can also be a sign of underlying disease. For instance, heart hypertrophy can lead to heart failure if it becomes too severe.
