EXPERT ANSWERS
Are there long-term risks from kidney donation?
Donating a kidney can save someone's life, and most kidney donors recover from the procedure with minimal complications. But are there long-term risks? Learn more from Dr. Erik Castle, a Mayo Clinic urologist.

What's the difference between herniated and bulging disks?
Disks act as cushions between the vertebrae in your spine. Over time, disks dehydrate, and their cartilage stiffens and can crack. These changes may result in a bulging disc or a herniated disc. Find out more about these two conditions, and which one might be the cause of your back pain, from Dr. Randy Shelerud, a Mayo Clinic physical medicine specialist.

HEALTH TIP OF THE WEEK
Do you know how to do a proper pushup?
Strength training includes exercises that use your own body weight for resistance. Pushups, for example, work your chest, arms, shoulders and upper body. Here's how to do a proper pushup:

  1. Position yourself on your hands and feet with your eyes facing the floor.
  2. Place your hands slightly greater than shoulder-width apart and your feet comfortably apart.
  3. Keeping your back and legs straight, slowly bend your elbows and lower your chest until your chin reaches the ground. You'll feel tension in the muscles in your back, abdomen and upper arms.
  4. Then, slowly return to the starting position.
