Research insights

Well established

• Blood-sugar control matters. Long-term studies in people with diabetes have shown that keeping blood sugar closer to target lowers the risk of nerve complications.
• B12 deficiency can cause nerve problems, and it is easy to test for. Correcting a confirmed deficiency is standard care.
• Exercise and balance training improve strength and balance and lower fall risk in older adults.
• Daily foot care and regular professional foot checks reduce serious foot problems in people with diabetes.

Still uncertain

Many supplements and devices are marketed for nerve discomfort. For most of them, the research is limited, small, or mixed. That does not always mean they cannot help anyone, but it does mean claims should be treated with caution.

Be wary of

Any product or programme that promises to "reverse" or "cure" nerve damage quickly, tells you to stop prescribed medicines, or relies only on testimonials. Talk to your doctor or pharmacist before trying something new.
