Vitamin B-12 Deficiency
People with inadequate vitamin B-12 intake may develop left hand numbness. This nutrient is available in animal products, including fish, meat, eggs and dairy foods, but some people don't consume enough of these foods or have trouble absorbing vitamin B-12. In addition to numbness in the hands and feet, symptoms of this vitamin deficiency may include fatigue, weight loss, memory problems and depression.
Consuming foods rich in vitamin B-12, taking supplements or receiving injections can help.11‘Office of Dietary Supplements - Vitamin B12.’ NIH Office of Dietary Supplements, U.S. Department of Health and Human Services, ods.od.nih.gov/factsheets/VitaminB12-Consumer,12‘Treatment - Vitamin B12 or folate deficiency anaemia.’ NHS Choices, www.nhs.uk/conditions/vitamin-b12-or-folate-deficiency-anaemia/treatment
