CNN's Dr. Sanjay Gupta introduces one family who just couldn't keep up with the bills.

Becky and James Specht lost their home they once owned to bankruptcy. In 2005 the Specht's filed chapter 13 and promised to pay $220 a month to dig themselves out from underneath their massive medical bills

"We was trying to keep up with our house payments and the car payments and the medical," said Becky.

Becky was a nurse when she was accidentally stuck by a needle and got Chronic Hepatitis B and later came the breast cancer diagnosis. Unable to work, she lost her medical insurance and the bills began to pile up.

"I was in the medical field for years helping people, I mean and all of a sudden I couldn't get help," Becky said.

After they filed, James had a heart attack. As a result he lost his job and insurance, which meant more unpaid bills for the Specht's to face.

"There's a lot of stress involved. No one should ever have to go through this," James said.

Dr. David Himmelstein, at Harvard Medical School, has been studying medical bankruptcy for nearly a decade. He says middle class Americans are bearing the brunt of medical bankruptcies.

"This is the main stream of America. They had insurance, they played by all the rules and yet they were ruined by their medical problems," said Dr. Himmelstein from the Cambridge Health Alliance.

In his newly released national study more than 62% of all bankruptcies were linked to medical problems.

"Virtually none of us has adequate coverage to withstand the financial consequences of a serious illness," Dr. Himmelstein said.

The Spechts are caught up in that struggle to survive. He's working, but only part-time. In 2007, they stopped their bankruptcy filing, simply unable to make the payments anymore. Becky has just found another tumor in her breast and they are now planning to file for bankruptcy again.

As for the new medical bills, "I can't open them, I can't worry about it, and I can't have my husband worrying about it," Becky said. The Spechts have been watching the whole health care debate very closely and are hoping that reform comes in time to help them.

Training Dogs to Detect Low Blood Sugar Levels

Doctors in Great Britain are training dogs to warn diabetic people when their blood sugar levels are too low.

This latest idea arose after diabetes patients said that when their blood sugar would drop dangerously low, their dogs would react by panting, licking, whining or barking. Now animal trainers in southern England are working with dogs that will eventually be paired with diabetic owners.
