Did you know that 1 in 11 Americans today has diabetes? Despite its prevalence, diabetes is an invisible disease. It affects me and women, people young and old, and people of all races, shapes and sizes. Often there are no outward signs from the 29 million Americans who fight this chronic illness every day. That's why there is a critical need to foster awareness and education while breaking down stereotypes, myths and misunderstandings about this growing public health crisis that affects so many of us.

Diabetes is more than the medications and devices used to manage it. For many, diabetes dictates how they organize their day, what they eat at every meal, how they choose to be physically active and how they spend their money. People with diabetes can have health care costs that are 2.3 times higher than someone without diabetes, as type 1 and type 2 require very specific forms of treatment.

Type 1 diabetes is an autoimmune disease usually diagnosed in children and young adults, and there is no known way to prevent it. Approximately 5 percent of people with diabetes have type 1, which means their body does not produce any insulin. Insulin is critical in order for the body to transport glucose (sugar) from the bloodstream into cells for energy. People with type 1 diabetes must take insulin every day to live.

Type 2 diabetes is the most common form of diabetes, accounting for 90 to 95 percent of cases in the United States, and is caused when the body does not produce or use insulin properly. Risk factors for developing type 2 diabetes include being overweight, having a family history of diabetes and having diabetes while pregnant (gestational diabetes). Some people with type 2 diabetes can control their blood glucose (sugar) with healthy eating and being active; others may require oral medications or insulin, especially as the disease progresses. Type 2 diabetes is more common in African Americans, Latinos, Native Americans and Asian Americans/Pacific Islanders, as well as older adults.

Some women develop gestational diabetes, high blood glucose (sugar) levels during pregnancy, which requires treatment to protect the health of the mother and the baby. Gestational diabetes affects approximately 9.2 percent of pregnant women.


What's New at Henderson Podiatry...

Introducing the K-Laser Cube IV!


The K-Laser is a new innovative treatment for pain management, arthritic joints, plantar faciitis, achilles tendonitis as well as foot injuries including ankle sprains. Laser therapy works by interacting with the tissues on a cellular level, speeding up metabolic activity to improve the nutrients crossing cell walls, promoting quick and healthy healing.

Patients suffering from painful diabetic neuropathy have found exceptional results with laser treatment and are very happy with the outcomes.

Sports teams such as the NY Yankees and the Cincinatti Bengals have made the K-laser a staple in the locker room, so much so that players are lining up to be treated. Laser pain therapy has helped them achieve a rapid recovery for tissue repair and alleviate inflammed joints.

Henderson Podiatry has made treatments very affordable and package discounts are available. Please call (717) 464-5603 to schedule your appointment and let the K-Laser help you painlessly treat your foot aches and pains!

Are you struggling with thick, yellow toenails or persistent plantar warts?  Come visit our Willow Street office to learn more about our additional laser treatment, the GenesisPlus.


The GenesisPlus laser is a treatment option available for fungal toenails and plantar warts. Laser light from GenesisPlus passes through the nail or wart and the surrounding tissue. The light is absorbed by pigment  which causes the pigment to heat. This "heat" kills or damages the fungal organism resulting in natural nail growth. With the warts, it heats the virus and healthy tissue ensues. This provides a quick and effective way to clear the nail  or wart without the use of anesthesia. Click here for more information and helpful videos!
