Can Hypothyroidism Cause Peripheral Neuropathy?

What is Hypothyroidism?

Hypothyroidism, or underactive thyroid disease, is a common condition that occurs when the thyroid gland does not produce adequate amounts of the thyroid stimulating hormone. Located in the lower front portion of the neck, the thyroid gland releases a crucial hormone that travels through the bloodstream. Thyroid hormones are essential in controlling how cells use energy. Hypothyroidism can impact the body’s general functionality.

What is Peripheral Neuropathy?

Peripheral neuropathy is a medical condition that develops when the peripheral nerves are damaged. The peripheral nervous system is the communication network connecting the central nervous system (the brain and spinal cord) to every other body part. There are more than 100 types of peripheral neuropathy, each with different symptoms and treatment options.

Can Hypothyroidism Cause Peripheral Neuropathy?

Hypothyroidism is a potential cause of peripheral neuropathy when left untreated. Although the exact link between these conditions is not fully understood, scientists have identified that hypothyroidism affects fluid retention in the body. This results in swollen tissues that exert pressure on the peripheral nerves, often manifesting as carpal tunnel syndrome.

Treating hypothyroidism can alleviate hypothyroidism-related peripheral neuropathy, often using levothyroxine to restore hormone levels to a healthy range.
