Surgery Bariatric surgery is a common cause of<unk> . Bariatric surgery, such as gastric bypass surgery, is often used for weight control of the morbidly obese. The disruption of the intestines and stomach from the surgery can cause absorption difficulties not only as regards copper but also for iron and vitamin B12 and many other nutrients. The symptoms of<unk>  myelopathy may take up to decades to develop. Zinc toxicity Increased consumption of zinc is another cause of<unk> . Zinc is often used for the prevention or treatment of common colds and sinusitis (inflammation of sinuses due to an infection), ulcers, sickle cell disease, celiac disease, memory impairment, and acne. Zinc is found in many common vitamin supplements and is also found in denture creams. Recently, several cases of<unk>  myeloneuropathy were found to be caused by prolonged use of denture creams containing high quantities of zinc. A literature review found two cases of<unk>  myelopathy secondary to parenteral zinc supplementation during chronic dialysis. Metallic zinc is the core of all United States currency coins, including copper-coated pennies. People who ingest a large number of coins will have elevated zinc levels, leading to zinc-toxicity-induced<unk>  and the associated neurological symptoms. This was the case for a 57-year-old woman diagnosed with schizophrenia. The woman consumed over 600 coins, and started to show neurological symptoms such as unsteady gait and mild ataxia. Hereditary disorders Menkes disease showing symptoms of the sparse, steel colored "kinky hair" and paleness Menkes disease is a congenital disease that is a cause of<unk> . Menkes disease is a hereditary condition caused by a defective gene involved with the metabolism of copper in the body. Menkes disease involves a wide variety of symptoms including floppy muscle tone, seizures, abnormally low temperatures, and a peculiar steel color hair that feels very rough. Menkes disease is usually a fatal disease with most children dying within the first ten years of life. Other It is rarely suggested that excess iron supplementation causes<unk>  myelopathy. Another rarer cause of<unk>  is celiac disease, probably due to malabsorption in the intestines. Still, a large percentage, around 20%, of cases have unknown causes.
