Symptoms of Vitamin E Shortage: Identifying Them
Vitamin E, a vital fat-soluble nutrient, plays a crucial role in protecting nerve membranes from oxidative damage. A deficiency in this essential vitamin can lead to a range of neurological and neuromuscular impairments, particularly affecting the central and peripheral nervous systems.
When an adult has less than 4 mg/L of vitamin E in their blood, they usually require supplementation. A normal level of vitamin E in the blood is typically between 5.5-17 milligrams per liter (mg/L).
The long-term effects of vitamin E deficiency on the central nervous system primarily involve neurological and neuromuscular impairments. Ataxia, or unsteadiness and lack of coordination, is one such effect. Vitamin E deficiency damages the cerebellum, the brain area responsible for motor skills and balance, leading to progressive difficulties in walking and maintaining stability, especially on smooth floors or when turning quickly.
Pigmentary changes in the retina may also occur, hinting at broader central nervous system involvement.
In the peripheral nervous system, vitamin E deficiency can cause peripheral neuropathy, characterized by tingling, prickling sensations, or numbness typically in the hands and feet (paresthesias). Damage to peripheral nerves can also result in muscle weakness and slower recovery from injuries due to impaired nerve signaling.
In some cases, vitamin E deficiency can lead to mild anemia and hemolysis, contributing to systemic weakness that may indirectly impact neuromuscular function.
The mechanism behind these neurological impacts is rooted in vitamin E's antioxidant properties. When deficient, increased oxidative damage affects both central and peripheral neurons and myelin sheaths, disrupting normal nerve transmission and muscle control.
A diet low in fat can cause a vitamin E deficiency, which can be remedied by adding fats to the diet. However, excessive levels of vitamin E can increase the risk of a stroke and early death. It's important to note that too much vitamin E can interact with blood thinners and chemotherapy medications.
Early detection and continuous treatment of a vitamin E deficiency can prevent neurological symptoms. Vitamin E deficiency can be treated with supplementation, and children and adults with inherited conditions may require high doses of vitamin E supplementation.
Vitamin E is an essential vitamin that the body needs to function, and it is mainly stored in the liver before being released into the bloodstream for use. It's crucial to maintain a balanced intake of vitamin E to ensure optimal nervous system health.
