  • Your Answer:
  • Correct Answer:

Thousands of people donate kidneys each year and stay healthy afterward. In fact, it's the No. 1 most common organ donated in the world. You can give a kidney to a friend, family member, or even a stranger.

 

Some people are born with one kidney. If one is missing, damaged, or removed, your other one can grow larger to become nearly the size of two kidneys. That helps it do the job of both.

  • Correct Answer:

Kidney stones form when there's too much of a certain substance (like calcium) in your urine. They can stay in your kidney or travel down the urinary tract, where you'd pee it out.

Early on, people with kidney disease usually don't have symptoms. But as things get worse, a change in bathroom habits -- having to go more or less -- can be a sign you have a problem. You may also feel tired, have muscle cramps, lose your appetite, and have swollen hands or feet and dry, itchy skin.

What do you need if your kidneys stop working?

What do you need if your kidneys stop working?

  • Your Answer:
  • Correct Answer:

When your kidneys completely stop working, your body fills up with wastes, fluids, and toxins. You either need a new kidney, or to go on dialysis -- that’s when a machine acts as an artificial kidney, cleaning your blood. You may need dialysis daily or a few times a week.

  • Your Answer:

Which medicines are more likely to hurt your kidneys?

Which medicines are more likely to hurt your kidneys?

  • Your Answer:
  • Correct Answer:

Because it's your kidney's job to filter your blood, too much of anything in your bloodstream can be bad. Certain pain medicine -- like aspirin, ibuprofen, and naproxen -- can damage your kidneys, especially if you take too much, too often. Don't take more than the recommended dose on the label. 

 

Drink plenty of water. And talk to your doctor if you use the drugs more than once in a while.
