Red light and near-infrared (NIR) light for diabetic care
Diabetes can interfere with the body&#;s production of nitric oxide and ultimately can disrupt normal blood flow. This is one of the explanations why diabetics are more likely to develop peripheral artery disease, a cardiovascular illness in which restricted blood vessels decrease blood flow to the limbs. Diabetic neuropathy is a peripheral nervous system condition that causes loss of sensation in the extremities, usually in the feet.
Diabetic foot ulcers (DFUs) are a disabling and common complication of diabetes that has a negative influence on one's quality of life and can lead to amputation and even premature death. Red light therapy (RLT), also known as low-level laser therapy (LLLT), has been shown to treat DFU. The evidence from this randomized double-blind placebo-controlled clinical trial, &#;demonstrated an increase in skin microcirculation that was due to athermic laser irradiation in patients with diabetic microangiopathy,&#; (Schindl A, et al.,). The intention of the study was to address the diabetic foot problems that were a result of angiopathy and neuropathy that accounted for 50% of all diabetic-related non-traumatic amputations. This study found that the low-level laser irradiation, in the patients with diabetic microangiopathy, resulted in &#;a statistically significant rise in skin temperature, whereas in the sham-irradiated control group, a slight but significant drop in temperature was found,&#; (Schindl A, et al.,). The increase in circulation was able to accelerate healing. This confirms the effects of LLLT increasing blood flow in areas of the body to which it is applied. Subsequently, having a profound implication for the treatment of slow-healing wounds found in diabetic patients.
In clinical studies, Red and NIR light therapy was found to help relieve discomfort associated with diabetic-related ailments such as supporting patients with dire diabetic neuropathy (DDN), a common complication of diabetes. LLLT was found to improve nerve function and &#;skin microcirculation in diabetic persons,&#;(Zang K, et al., ). Healing foot ulcers is one of the most promising outcomes of the benefits of red and near-infrared light treatment for diabetics.
In this pilot study, prior to regular care and dressing, laser treatment was administered once a week to the participants in the study. Patients with similar DFUs and clinical features were treated with conventional therapy as a control group. The purpose of the selected pilot study was to &#;investigate the efficacy of an advanced class IV laser (emitting four wavelengths) on Wagner stage 1 and 2 neuroischemic DFUs of five patients with type 2 diabetes who were unresponsive to conventional treatment for at least 12 weeks,&#; (Maltese G, et al., ). Despite the limitations of this proof-of-concept investigation, the findings suggest that laser therapy provided by a class IV laser can have a considerable impact on the healing process of neuroischemic DFUs that have been resistant to normal treatment.
In terms of tissue regeneration and increased blood circulation, the following effects were assumed to be the mechanism of laser action:
The effects of diabetic peripheral neuropathy (DPN) on both type 1 and type 2 diabetes were investigated in this study. The effects of LLLT on, &#;motor and sensory nerve conduction velocity (NCV), and foot skin microcirculation," (Yamany, A & Sayed H, ) was examined amongst the 30 participants involved, . It was concluded that "in the laser group, the microcirculation at the three points was increased significantly with no significant change in the control group; post-treatment measurement comparison between groups found a highly significant difference in favor of the laser group,&#; (Yamany, A & Sayed H, ) ). DPN treatment focused on improving microcirculation and strengthening nerve regeneration with red/NIR light therapy as the wound-healing biological effects would promote blood flow and reduce inflammation. Ultimately, light therapy will improve blood circulation by supporting the growth of small capillaries in the targeted treatment areas.
In the research cited; it was hypothesized that the increase in cutaneous blood flow is reflected by a comparable impact at the endoneurial level, implying that an increase in nerve blood flow is a mechanism by which a laser produces peripheral nerve function improvement. An intriguing finding to regenerate nerves!
Nerve regeneration, blood circulation&#; What more can Red Light Therapy do for diabetic health?
According to the research, red light therapy has been known to restore diabetic patients' normal healing potential by stimulating mitochondria and improving ATP generation. By addressing mitochondrial dysfunction, you have the opportunity to energize cells and trigger a cascade of positive biological processes and increased health.
When there is a chronic blood sugar imbalance, cells can become stressed, unable to function correctly, and unable to repair themselves. Blood sugar imbalances are known to produce oxidative stress, which can lead to inflammation. According to these findings, near-infrared light serves as an antioxidant and decreases inflammation. One of the main reasons for diabetic neuropathy is a lack of cellular energy, often known as mitochondrial dysfunction, therefore restoring normal mitochondrial activity is important.
In this randomized controlled trial, comparing before and after LLLT treatments, diabetic patients who received laser therapy had better neuropathy outcomes than diabetic patients who received the placebo. To acquire repeatable outcomes, more research is needed to evaluate different types of lasers, as well as variable dosage and exposure levels required in different phases of diabetic neuropathic care. Overall, LLLT and wound healing are an intricate part of diabetic care. It is aimed at reversing the loss of tissue integrity in diabetic patients.
Red Light Therapy can be looked at as a valuable adjunct treatment for addressing the issues caused by diabetes; whether it is to manage symptoms or help prevent further damage, or speed up healing. The growth of healthy tissue can be supported with light therapy as the mitochondrial activity gets restored and then may assists to repair skin ulcers and relieve neuropathic discomfort, as well as keep the peripheral nervous system running smoothly. Red light therapy is a natural and safe treatment that can help your body's natural healing systems work more effectively. Always check with your healthcare provider before using any new treatment regimen for diabetes.
