Going to the doctor, starting a new diet or trying a new fitness regimen -- all these things can be nerve-wracking.

So, why not focus on health in a "fun and casual environment?," said Vicki Hoffman of Stamford Hospital.

Health seekers can find just that at the Health, Wellness and Sports Expo 2012, taking place at the Chelsea Piers Connecticut sports complex on Saturday and Sunday, Sept. 22 and 23.

"Sometimes, people can get overwhelmed by the thought of seeing a physician," Hoffman said. "This event is a non-threatening way for you to engage and learn more about your health."

The TMK Sports and Entertainment-sponsored event will feature nearly 75 exhibitors, plus fitness and dance demos, celebrity athletes and more, under one roof.

Exhibits will cover all aspects of staying in shape -- weight management, children's wellness, sports medicine, fitness programs, green technology and financial health.

"This is a super important community event to promote better health and wellness," said Tammi Ketler, co-owner of TMK Sports & Entertainment. "This event is for the whole family -- we have something for everybody."

Stamford Hospital physicians will provide free health screenings for cardiac and stroke assessment, blood pressure and pulmonary function.

The hospital's Mobile Wellness Center will be parked just outside Chelsea Piers for free mammograms.

Visitors can head over to the Ask the Doc booth, manned by Stamford Hospital physicians.

"We'll have a variety of specialists, including orthopedic surgeons, cardiologists and pediatricians," Hoffman said.

On the nutrition side, Jamie McIntyre, a registered dietician from Grade A Shoprite, and Carlon Colker, Fairway's health and nutrition consultant, will be on hand. Area purveyors will provide samples of healthy foods and beverages.

For youngsters, Greenwich Track Club and Lacrosse Unlimited will host activities and skills competitions.

Stamford Hospital's Children's Specialty Center and Yale-New Haven Children's Hospital will be promoting healthy eating as part of National Childhood Obesity Awareness Month.

Patrons who bring one or more nonperishable food items to the free expo will be given a raffle ticket to win a healthy door prize. (Raffle tickets also can be purchased for $5.)

All food and proceeds will be donated to the Food Bank of Lower Fairfield County for more than 70 nonprofit agencies in Fairfield County.

"Food is an important component of health and we are grateful for the support that this expo will bring to our food bank," the Food Bank's Kate Lombardo said.

Organizers said there are always ways to get in better shape and no aspect of health and wellness will go unchecked at the event.

"Sometimes we look great on the outside," Hoffman said, "But knowing what's happening on the inside will help to manage our health and wellness, too."
