A bad economy is no reason to ignore your health, said Dr. Nieca Goldberg, director of the Women's Heart Program at the NYU Langone Medical Center in New York City. "Even in hard times, regular screenings are important," she said. "Basically, it's an investment in your health."

Catching medical problems early can save you in the long run, she added. For instance, if a doctor detects slightly elevated blood pressure, you might correct it by cutting back on salt and getting more exercise. That's healthier and cheaper than waiting until the pressure is so high you need medications, Goldberg said.

Other ways to save:

• Ask your physician if a cheaper generic version of any medicine you need is available.
• If you've lost your insurance, be aware that many medical clinics have a sliding scale. Ask your doctor, your county officials or city personnel for referrals.
• Consider preparing more food on your own rather than turning to fast food. "That's the healthiest and may be cheaper," Goldberg said.
• Look for sales in the grocery store as you would in other stores. Buy whichever healthy fruits and vegetable are on sale that week.
