What is Diabetic Peripheral Neuropathy?
Diabetic peripheral neuropathy (DPN) results from nerve damage caused by long-standing high blood sugar levels. It is a common complication of both type 1 and type 2 diabetes. DPN primarily affects the nerves in the legs and feet but can also involve the arms and hands. DPN generally develops gradually and may lead to complications that can greatly impact the quality of life.
Symptoms
The symptoms of DPN may vary depending on the severity of the condition and the nerves affected. Some common symptoms include:
- Numbness, tingling, shooting or burning pain in the hands, arms, feet, or legs
- Inability to feel pain when there is a cut in the skin
- Difficulty sensing temperature
- Loss of balance or coordination
- Muscle weakness
- Small muscle wasting in the feet

Complications
If left untreated, DPN can lead to several complications:
- Fall risk: Loss of balance and coordination can increase the risk of falls and suffering injuries.
- Foot ulcers: Numbness may make it difficult to feel a minor injury or pain from calluses or corns, leading to the development of ulcers.
- Infections: The inability to feel pain can make it challenging to notice wounds, hence increasing the risk of severe infections
- Charcot’s foot: A condition that causes the weakening of bones and joints, leading to severe foot deformities and may cause disability.
- Amputation: Severe infections or ulcers that don’t heal may end up needing amputation of the affected limb to prevent the spread of infection.
Treatment Options in Singapore
There is no definite cure for DPN, but proper control of diabetes and a comprehensive management plan can help control symptoms, prevent complications, and improve the quality of life. Treatment options include:
- Blood sugar control: Maintaining blood sugar levels within the target range is crucial to prevent the progression of DPN.
- Medication: Prescription medications from your doctor may help manage DPN pain and discomfort.
- Physical therapy: Exercises, stretches, and balance training can help improve strength, coordination, and mobility.
- Orthotics and footwear: Proper footwear and custom orthotics can protect the feet, reduce pressure, and prevent ulcers.
- Regular foot care: You should inspect your feet daily, keep them clean and dry, and promptly address any injuries to help prevent complications.
- Regular diabetic foot screening: We recommend at least a foot screening once or twice a year to monitor your foot health.

Frequently Asked Questions on Diabetic Peripheral Neuropathy
Are there any specialist clinics for diabetic peripheral neuropathy in Singapore?
DPN is managed across several disciplines in Singapore rather than at a single specialist clinic. Endocrinologists and family doctors oversee blood sugar control and the broader diabetes picture. Neurologists may be involved when symptoms are severe or atypical. Podiatrists play the day-to-day role of protecting the foot from the complications that DPN drives, such as ulceration, infection, and structural change. At Straits Podiatry, we work alongside your primary care or specialist team to manage the foot side of DPN, including diabetic foot screening, footwear and orthotic prescription, and early treatment of any skin or nail changes that could turn into wounds.
Will controlling my diabetes cure diabetic peripheral neuropathy?
Tight blood sugar control is the foundation of managing DPN, but it does not reverse nerve damage that has already happened. What good blood sugar control does is slow or stop the progression of further nerve damage and reduce the risk of complications such as ulceration. Some patients also notice that symptoms like burning or tingling pain ease once their blood sugar is consistently in range. Your endocrinologist or family doctor leads on the blood sugar side. Podiatric care is the parallel layer that protects your feet while your diabetes is being managed.
Is it too late to start controlling my sugar after I have diabetic peripheral neuropathy?
It is never too late. Even after DPN has developed, getting blood sugar back into a safe range reduces the rate of further nerve damage, lowers the risk of foot ulceration, and improves the body’s general ability to heal small injuries. The damage already present may not reverse, but the trajectory of the condition can change once sugars are stable. We encourage every patient with DPN to keep working with their diabetes team on blood sugar control, even if the diagnosis has been in place for years.
What can happen if my feet are numb from diabetic peripheral neuropathy?
The numbness from DPN carries a practical risk that is easy to underestimate. The foot’s natural pain-warning system is no longer reliable, so a small cut, a blister from a new shoe, a sharp object stepped on, or pressure from an ill-fitting sandal can go unnoticed and develop into an ulcer. Skin changes such as calluses and corns can also build up pressure under the skin and lead to a wound underneath. In more advanced cases, weakened bone in the foot can fracture or collapse without obvious pain, which is the clinical picture seen in . Daily foot self-checks, properly fitted footwear, and regular review by a podiatrist help catch small problems before they progress.
How can podiatrists help my diabetic peripheral neuropathy?
Podiatrists do not treat the nerve damage itself, which is managed through blood sugar control and, where appropriate, medication from your doctor. The podiatric role is to manage the foot. At Straits Podiatry, that includes:
- Diabetic foot screening, covering vascular and neurological assessment plus footwear review
- Treatment of skin and nail conditions before they become wounds, such as calluses, corns, ingrown toenails, and fungal infection
- Wound and ulcer management if a problem develops, including offloading
- Prescription of properly fitted footwear and to redistribute pressure
- Ongoing review at intervals that match your individual risk level
Patients with confirmed DPN are usually placed on a regular review schedule rather than only being seen when symptoms appear, because by the time pain is felt the underlying damage is often more advanced.
