Vitamin Levels
Testing for vitamin D and B12 deficiency, both of which worsen nerve symptoms and delay wound healing.
Key Takeaways
- Long term metformin use lowers vitamin B12 in a significant number of patients.
- B12 deficiency causes burning, tingling and numbness that mimics diabetic neuropathy.
- Vitamin D supports bone strength and wound repair, and deficiency is very common in India.
- Both deficiencies are cheap to test and straightforward to correct.
Why Check Vitamins in Diabetic Foot Care?
Because two very treatable deficiencies quietly make the foot worse. Vitamin B12 is needed for healthy nerves, and metformin reduces its absorption over years of use. As a result, patients often blame diabetes alone for burning feet when part of the problem is correctable within months.
Vitamin D matters differently. It supports bone health, immune function and tissue repair, all of which a healing foot needs. Deficiency is widespread here despite plenty of sunshine, largely because of indoor working hours and covered clothing.
What Symptoms Suggest a Deficiency?
- Burning or pins and needles in both feet
- Numbness that has worsened noticeably in recent months
- Unexplained tiredness and weakness
- Bone or muscle aches, particularly in the legs
- Slow healing wounds despite good sugar control
How Are Deficiencies Corrected?
B12 is replaced with injections or high dose tablets, and nerve symptoms often improve within weeks to a few months. Vitamin D is corrected with a supervised dosing schedule, then maintained. Levels are rechecked afterwards, because correction without confirmation is guesswork.
Alongside this, we reassess nerve function through our neuropathy assessment, so improvement can be measured rather than assumed.
What Do These Tests Cost?
Both vitamin tests are modestly priced and normally ordered together with other blood work, which keeps the total reasonable. The charge is confirmed before samples are collected.
Correction itself is inexpensive, since B12 and vitamin D replacement are among the cheapest treatments in medicine. Given that a deficiency can be quietly worsening your nerve symptoms for years, testing early is genuinely good value.
