Nutrient deficiencies can also play a role. A lack of Vitamin B12 can interfere with proper nerve function. Because B12 is mostly found in foods like meat, eggs, dairy products, and fortified cereals, people following vegan or vegetarian diets may sometimes need supplements to maintain healthy levels.
Mineral imbalances may lead to similar sensations. Low levels of calcium, potassium, or sodium can disrupt the signals traveling through your nerves, resulting in tingling or numbness. Dehydration, certain medications, or underlying medical conditions can contribute to these imbalances. Drinking enough water and maintaining a balanced diet can help support normal nerve activity.
When It Could Mean Something More
Although occasional numbness is usually harmless, persistent or worsening symptoms may indicate an underlying issue.
For example, people with chronically high blood sugar may develop Diabetic Neuropathy, a condition that damages peripheral nerves and can lead to numbness, tingling, or burning sensations in the hands and feet.
