What Causes Peripheral Neuropathy in Diabetics?
In Diabetic Neuropathy Part I, we explored how poor systemic blood circulation contributes to nerve damage in diabetic patients. In this post, we turn to the second most common cause: poor peripheral fluid circulation — and what Chinese Medicine reveals about why it happens and how it progresses.
A Chinese Medicine Perspective on Fluid Retention
It is common for people living with diabetes, heart disease, or kidney disorders to develop edema — swelling in the arms, legs, or abdomen. From a Chinese Medicine standpoint, this is largely attributed to a Kidney imbalance that disrupts the body’s ability to regulate water distribution.
When fluids accumulate — most often in the tissues of the lower extremities — they exert pressure on underlying vascular structures, including veins and arteries. This compression cuts off blood circulation, producing the hallmark symptoms of peripheral neuropathy: tingling, burning, and numbness.
Western medicine refers to this phenomenon as compartment syndrome. Diuretics such as Lasix are commonly prescribed to reduce excess fluid buildup.
How Does Fluid Retention Affect the Body?
Skin Changes
When the lower legs become saturated with fluid the body cannot expel, the skin becomes taut, hard, and heavy. Joints may stiffen and become difficult to move. Because these retained fluids contain toxins that should have been eliminated through urination, cellulitis can develop — causing redness, pain, and localized heat.
The skin takes on a shiny, stretched appearance, and affected limbs enlarge noticeably. A simple indicator: if your socks or shoes leave deep indentations that linger long after removal, fluid retention may be a factor.
Try this self-test: Press gently on a swollen area with three fingers for about 10 seconds. If indentations remain after you lift your fingers, you are likely experiencing pitting edema — a clinically recognized sign of significant fluid retention. Widespread edema affecting multiple areas of the body is called anasarca, a more severe condition requiring prompt medical attention.
Visual Vascular Signs
Visible signs on the skin’s surface can vary. Some patients develop spider veins, while others show no visible discoloration at all. Varicose veins are not typical in fluid-retention-related neuropathy but may occasionally appear around the knees.
Pain Progression
Fluid-related neuropathy pain tends to follow a predictable progression:
- No pain initially — swelling may be present without discomfort
- Itching or sensitivity — early warning signs in one or more areas
- Heightened sensitivity — affected areas become painful even to light touch
- Tingling → Burning — pain intensifies as fluid pressure increases
- Numbness — signals advanced tissue and nerve damage; pain may cease as nerves die
Tissue Damage
Interestingly, tissue damage from edema tends to develop more slowly than damage caused by poor systemic blood circulation. Blood delivers vital oxygen and nutrients continuously, whereas fluid circulation fluctuates based on both internal and external factors — sometimes even changing within a single day.
External factors include sudden increases in dietary sodium, which causes temporary but significant water retention and further restricts circulation in the extremities during periods of acute swelling.
Internal factors include hormonal imbalances — often Kidney-related in Chinese Medicine — that cause ongoing fluid retention and unexplained weight gain.
In more advanced cases, the skin may develop red, hot, painful patches — a condition known as phlebitis, or inflammation of one or more veins.
The Neuropathy Shuffle
One of the most recognizable — and heartbreaking — signs of advanced peripheral neuropathy is a change in the way a person walks.
As sensation is progressively lost in the feet, patients compensate with what practitioners often call “The Neuropathy Shuffle” — a slow, flat-footed, zombie-like gait that replaces the normal heel-to-toe movement of walking. This shuffle develops because the loss of feeling in the feet makes normal weight-shifting unreliable, greatly increasing the risk of stumbling and falls.
How Acupuncture and Chinese Medicine Can Help
At Dr. Blackstone Acupuncture, we address the root causes of diabetic neuropathy — not just the symptoms. Chinese Medicine offers targeted treatment strategies to support Kidney function, improve fluid metabolism, restore healthy circulation to the extremities, and slow or reverse the progression of neuropathy symptoms.
If you or a loved one is experiencing swelling, tingling, burning, or numbness in the legs or feet, early intervention is key.
