Alternatives for Your Aching Feet Part 1

Two treatment options tackle the pain of DPN.

If you have diabetes and your feet are bothering you, it could very well be diabetic peripheral neuropathy or DPN. DPN is not the only cause for tingling, painful, numbness, or other weird feelings of your feet, but it is one of the primary causes. The only way for you to really know is to check it out with your healthcare team and get the right diagnosis.

Prevention is the best treatment for DPN. This means not only managing your blood glucose, but your blood pressure and lipids as well.

There are many approved treatments for DPN. The truth is, some work for some people, and for some, none has worked. This is one reason people turn to alternative therapies. There are a lot of alternative therapies touted about, but remember without the science, no one, including your healthcare team, can guarantee that they are either safe or effective. So, buyer be careful and be aware! And be sure to talk with your healthcare team before trying any alternative and complimentary treatments.

Two alternative treatments for DPN that have shown some benefit and have some science to back them up are alpha-lipoic acid, and capsacain.1

Alpha-lipoic acid (ALA)

Alpha-lipoic acid (ALA), also known as thioctic acid, is an antioxidant used in Germany to treat peripheral neuropathy. ALA has been shown to improve nerve blood flow and distal nerve conduction and endoneurial glucose uptake and energy metabolism in animals.2,3

Adverse effects, cautions, and drug interaction have shown to be mild. They include headache, skin rash, stomach upset at high doses (>600mg/day) and possible hypoglycemia.4,5 Health care providers and patients need to be aware that ALA is a chelating agent that might cause mineral shortages, therefore iron levels need to be periodically checked. A vitamin B supplement should be taken if ALA is given to people who are thiamine-deficient (eg, alcoholics). If you are taking other medications that chelate with ALA (eg, anacids), space the dosing of these by at least 2 hours.

In clinical trials, improvements were more likely to be seen after short-term parental use (administered elsewhere other than the mouth, e.g. intravenous infusion) rather than long-term oral use. It is not available in the United States as a parenteral formulation, but there are oral doses of 30mg and higher. The optimal dose is currently unknown, but a minimum treatment of three weeks is most likely required.

At this time, there is not enough research on the long-term benefits of ALA. Because ALA has limited side effects, and is already approved in Germany for DPN, one can consider this as a treatment option for people who have mild to moderate DPN.

If this sounds like something you want to try, discuss this first with your healthcare team. Don't forget to bring up the potential side effects and vitamin and mineral deficiencies associated with ALA. If you are all in agreement, discuss the right dosage for you and choose a trusted source of ALA. Remember, vitamins and supplements are not regulated, so do your homework and choose brands you can trust.

Stay tuned for next month's discussion of capsaicin.

I have spent the past three days dealing with an evil stomach bug. Gastro issues, bloodsugar issues and a headache for the ages - along with a low grade fever - left me in bed trying (and mostly failing) to rest. I'm back at work today after two sick days, but still on slo-mo. Weird bloodsugars are always my "getting sick" miner's canary. Everyone knows what a miner's canary is, right? Back in the day, miners would keep a caged bird (often a canary) with them in the mine....
