numbness diet considerations

Overview

Numbness is a loss of feeling in a part of your body. It can also feel like tingling or 'pins and needles.' Sometimes it is temporary, like when your foot falls asleep. In other cases, it can be a sign of a health problem. Your diet can affect how well your nerves work, and eating well may help prevent or manage some types of numbness.

Yes, almost everyone experiences temporary numbness at some point. Long-lasting or unexplained numbness is less common but still affects many people.

Numbness can affect people of all ages. It is more likely in people with diabetes, vitamin B12 deficiency, or disorders that affect the nervous system. Older adults may experience it more often due to circulation or nerve changes.

Symptoms

Common symptoms

• Tingling or 'pins and needles'
• Loss of feeling or a 'dead' sensation
• Burning or a feeling of heat
• Weakness in the affected area
• A feeling like wearing a tight glove or stocking

Symptoms in children

• Frequent numbness after sitting in one position
• Tingling or pain after an injury
• Changes in walking or using hands
• Complaints of a body part feeling 'funny' or 'asleep'

Symptoms in older adults

• Numbness in the feet or hands, often linked to diabetes or poor circulation
• Dizziness or balance problems with numbness
• Numbness with memory or vision changes
• Symptoms that happen after specific activities, like walking

Causes

Main causes

• Lack of essential vitamins and minerals, especially vitamin B12, B6, and magnesium
• Diabetes, when high blood sugar damages nerves
• Pressure on a nerve, like a slipped disc or carpal tunnel syndrome
• Poor blood circulation to the nerves
• Alcohol misuse, which can affect nerve nutrition
• Autoimmune conditions that attack the nervous system, like multiple sclerosis
• Medications that affect nerve signals (talk to your doctor about any side effects)

Risk factors

• Diabetes or high blood sugar
• Vitamin B12 deficiency, which is more common in older adults and strict vegetarians
• Long-term alcohol use
• Exposure to toxins or certain industrial chemicals
• Family history of nerve disorders
• Kidney, liver, or thyroid disease

When to see a doctor

See a doctor urgently if:

• You have sudden numbness on one side of your body, with weakness, confusion, or trouble speaking.
• You have numbness after a head, neck, or back injury.
• You have numbness with chest pain, difficulty breathing, or fainting.
• You lose control of your bladder or bowel.

Book a routine appointment if:

• Numbness that lasts more than a few hours without a clear cause.
• Numbness that happens repeatedly or gets worse.
• You have diabetes and develop numbness or tingling in your feet or hands.
• You feel tired, weak, or unsteady along with numbness.

Diagnosis

A doctor will ask about your symptoms, medical history, and habits such as alcohol use. They will also do a physical exam to check your strength, reflexes, and feeling in different parts of your body.

Tests that may be done

• Blood tests to check vitamins, blood sugar, kidney function, and thyroid levels
• Nerve conduction studies to see how fast signals travel along your nerves
• Electromyography (EMG) to check the electrical activity of muscles
• Imaging tests, like an MRI, if a structural problem is suspected
• A skin biopsy in rare cases to look at nerve endings

What to expect at your appointment

Your doctor may refer you to a neurologist (a specialist in brain and nerves) or a dietitian. The process usually takes some time. Bring a list of your symptoms, medications, and questions to the appointment.

Treatment

Treatment for numbness focuses on the underlying cause. If a vitamin deficiency is the reason, correcting it may ease symptoms. If diabetes or another condition is involved, managing that condition is key. A healthy diet supports nerve repair and overall well-being.

Self-care at home

• Eat a balanced diet rich in vegetables, fruits, whole grains, and lean proteins.
• Stay hydrated by drinking water throughout the day.
• Move regularly and avoid sitting still for long periods.
• Limit alcohol and avoid smoking.
• Check your feet daily if you have diabetes, and keep them clean and moisturized.
• Follow your doctor's advice for managing diabetes or other conditions.

Medical treatments

Medical treatments vary depending on the cause. A doctor may recommend physical therapy, occupational therapy, or medicines to treat an underlying condition. If you have a vitamin deficiency, they may suggest a supplement (ask your doctor before taking any). They may also adjust medications that could be causing numbness. Always talk to your healthcare provider before starting or stopping any treatment.

When is surgery considered?

Surgery is only considered when a nerve is being compressed by an injury or a structural problem, such as a herniated disc or carpal tunnel syndrome. Your doctor will discuss this option if it applies to you.

Living with this condition

Living with numbness can be frustrating, but small changes can help. Protect the numb area from injuries, use handles or grips, and allow extra time for tasks that need careful hand or foot movements. Work with your healthcare team to monitor your symptoms and adjust your diet and treatment as needed.

Lifestyle tips

• Keep regular meals that include a good mix of proteins, healthy fats, and carbohydrates.
• Include foods rich in B vitamins, such as leafy greens, eggs, legumes, and dairy (if tolerated).
• Exercise moderately, like walking or swimming, to improve circulation, but avoid overexerting a numb or weak limb.
• Take breaks during repetitive activities like typing or using hand tools.
• If you have diabetes, monitor your blood sugar and keep it within your target range.

Diet and exercise

A balanced diet helps maintain healthy nerves. Focus on whole foods, colorful vegetables, fruits, nuts, seeds, and lean proteins. Stay within your calorie needs. Gentle exercise several times a day can improve blood flow. If you have trouble balancing, use a walking stick or ask a physical therapist for safe exercise ideas.

Mental health and emotional wellbeing

Numbness can cause worry, frustration, or sadness, especially if it affects daily activities. It is normal to feel this way. Talk to your doctor about your concerns, and reach out to supportive friends or family. If emotional stress becomes overwhelming, ask your healthcare team about counseling or local mental health services.

Prevention

Not all cases of numbness can be prevented, but a nutritious diet, regular exercise, avoiding excessive alcohol, and keeping health conditions like diabetes under control can reduce your risk.

Vaccines

There is no vaccine for numbness itself. However, staying up to date on recommended vaccines can help prevent infections that might affect nerves.

Screening programmes

Regular health check-ups can catch conditions like diabetes or vitamin deficiencies early. Ask your doctor if you should have your vitamin B12 or blood sugar levels checked, especially if you are over 50 or have risk factors.

Complications

If left untreated

• Falls and injuries from reduced feeling in your feet or hands
• Burns or cuts that go unnoticed and become infected
• Permanent nerve damage if the cause is a serious deficiency or disease
• Worsening of the underlying condition, such as diabetes or multiple sclerosis

Long-term outlook

With the right care, many people experience improvement in their symptoms. Once the cause is known, you and your healthcare team can create a plan. Even when full feeling does not return, you can learn to manage the condition and maintain a good quality of life.
