Pilot study shows low-level laser light can reduce cholesterol, triglycerides
April 2, 2009--A clinical study originally designed to investigate how dissolved fat affects body chemistry led researchers to discover that laser light can disrupt cholesterol formation. Subsequent research concluded that 75 percent of study participants had an overall reduction in cholesterol serum of 16.1 points. Ryan Maloney, medical director of Erchonia Medical Inc. (McKinney, TX) is reporting the results at this week's Annual Conference of the American Society for Laser Medicine and Surgery (ASLMS) in National Harbor, MD.
"Since low-level laser therapy was proven to affect transcription factors, we wanted to determine if laser therapy could serve as a subtle, non-invasive instrument to lower cholesterol and triglyceride serum levels," said Maloney. Twenty volunteers between the ages of 18 and 65 participated in the non-controlled, non-randomized study. They received low-level laser treatments three times per week for two weeks, with each treatment session lasting approximately 40 minutes. Treatments were administered across the abdomen and waist area, and wrapping around the lower back--an area that generally contains the most concentrated pockets of subcutaneous fat. The laser produced 17.5 milliwatts of energy at 635 nanometers.
The 75 percent of study participants that demonstrated overall reduction in cholesterol serum levels had a reduction ranging from -1.0 to -31.0 mg/dL. For those participants demonstrating an overall reduction in cholesterol serum levels, 93 percent experienced a reduction in LDL levels (commonly referred to as "bad cholesterol"), with 47 percent revealing a reduction in LDL levels without experiencing a reduction in HDL levels (or "good cholesterol"). Of the 20 participants, 60 percent demonstrated a reduction in triglyceride levels.
"We were incredibly surprised by these findings, especially given that we stumbled upon this observation by accident," said Maloney. "It's exciting to see laser technology shift in the direction of treating chronic conditions with the potential to one day serve as a viable alternative to leading prescription medications used to treat high cholesterol."
Maloney said this research is now moving into a randomized placebo-controlled, double-blinded clinical trial expected to begin at multiple sites later this year. The clinical trial will investigate, among other things, the long-term effects of low-level laser irradiation on cholesterol and triglyceride serum levels in hopes of establishing treatment guidelines to ensure levels are maintained over time. "Low-level laser therapy is gaining popularity across the medical community as an effective form of preventative medicine, and I think this trend will certainly continue in the future," he said.
