Large handbags are a health hazard for women, experts warned.

Bags for women have become bigger and heavier as designers combinebriefcaseswith handbags and straps have become longer but the extra leverage has many patients complaining of neck, shoulder and back problems.

"I see so many women with neck pains and headaches and what I usually do is look for their purse and pick it up," said Jane Sadler, a family practice physician at Baylor Medical Center in Garland, Texas.

"We take it over to the scale and weigh it and usually they're anywhere from 7 to 10 pounds (3.1-4.5 kgs)...We're really going to see women with more and more problems later on if we continue the big purse craze."

William Case, a physical therapist in Houston, Texas, said an aggravated neck or shoulder can lead to upper back problems, meaning pain may then be felt while working at a computer or playing sports.

He urged designers "to place a cute, educational caution tag on all bags to inform of potential neck and shoulder dangers."

Above all, he recommended correct posture while carryingbulkypurses, keeping the head and shoulders aligned upright. Patients should also frequently change the size and weight of purses carried.

"The extra-large purses are quite phenomenal. They look beautiful when the women wear them, but I don't know how aware they are of the potential problems," Case said.
