When neuropathy can become dangerous

Peripheral neuropathy is a condition that affects millions of people worldwide and often begins silently—a tingling sensation in the feet, a slight numbness in the hands, a feeling that something "isn't right."

But what many don't realize is that if left untreated, neuropathy can progress and become much more dangerous than it seems.

What is neuropathy

Neuropathy occurs when peripheral nerves —those that connect the brain and spinal cord to the rest of the body—are damaged.

These nerves are responsible for transmitting sensations, controlling movement, and regulating automatic functions such as blood pressure and heart rate.

When something compromises these nerves, symptoms such as:

• Tingling or numbness in the hands and feet;

• Burning sensation or “shocks”;

• Loss of sensation;

• Intense and persistent pain;

• Difficulty walking or maintaining balance.

At first, these signs may seem harmless. But therein lies the danger.

When neuropathy becomes a real threat

While neuropathy itself isn't a fatal disease , the complications it causes can pose serious health risks .

Here are some situations in which it can become dangerous:

1. Wounds that do not heal and risk of infections

Loss of sensation in the feet causes small wounds, blisters, or cuts to go unnoticed.

These injuries can worsen, leading to deep ulcers , infections, and even amputations , especially in people with diabetes .

If the infection spreads to the bloodstream, it can cause sepsis , a potentially fatal condition.

2. Autonomic neuropathy — when it affects vital organs

Some types of neuropathy affect the autonomic nerves , which control involuntary body functions.

This can cause:

• Sudden drops in blood pressure;

• Irregular heartbeat;

• Digestion and gastric emptying problems;

• Difficulty controlling the bladder or bowels.

• In severe cases, there may be a risk of cardiac or circulatory collapse , especially in people with pre-existing conditions.

3. Chronic pain and psychological impact

Neuropathic pain is different from regular pain—it can be constant, burning, or accompanied by shocks. This type of pain affects sleep, mood, and energy, leading to anxiety, depression, and social isolation. Over time, physical and emotional suffering can reduce immunity and worsen existing conditions.

Who is most vulnerable

• Neuropathy can arise from several causes, but the risk is higher in:

• People with type 1 or type 2 diabetes ;

• Elderly (natural nerve degeneration increases with age);

• Anyone who has high cholesterol, high blood pressure or obesity ;

• Individuals with vitamin deficiencies (such as B12);

• People who consume alcohol excessively or use certain medications;

• Patients with kidney or autoimmune diseases .

Recognizing these risk factors is essential to taking action before the disease progresses.

What to do to avoid complications

The good news is that neuropathy can be controlled —and the earlier it's detected, the better your chances of avoiding serious damage .

Here's how to protect yourself:

• Keep regular check-ups with your doctor , especially if you have diabetes or suspect symptoms.

• Ask for a foot sensitivity test , such as the monofilament test.

• Control blood sugar , cholesterol and blood pressure.

• Avoid tobacco and alcohol , which further damage your nerves.

• Take care of your feet daily: check for wounds, calluses, blisters, or discoloration and seek professional help if you notice anything unusual.

• Practice light to moderate physical activity , which stimulates circulation and helps with nerve regeneration.

Neuropathy can start out mild, but if left untreated, it can become a dangerous and debilitating condition .

It can impair mobility, cause serious infections, and affect the functioning of vital organs.

Therefore, early diagnosis and appropriate treatment are key to avoiding complications and preserving quality of life.

If you experience numbness, tingling, or pain in your feet and hands, don't ignore the signs —see a doctor and investigate the cause.

Taking care of your nerves is taking care of your life.
