A LOT OF YOU DON'T KNOW ME PERSONALLY, BUT I THOUGHT ID SHARE THIS BIT OF INFO WITH YOU.....
I HAVE A RARE DISEASE CALLED Wilson's Disease....
What is Wilson disease?
Wilson disease is a genetic disorder that prevents the body from getting rid of extra copper. A small amount of copper obtained from food is needed to stay healthy, but too much copper is poisonous. In Wilson disease, copper builds up in the liver, brain, eyes, and other organs. Over time, high copper levels can cause life-threatening organ damage.
Who gets Wilson disease?
People who get Wilson disease inherit two abnormal copies of the ATP7B gene, one from each parent. Wilson disease carriers, who have only one copy of the abnormal gene, do not have symptoms. Most people with Wilson disease have no known family history of the disease. A person's chances of having Wilson disease increase if one or both parents have it.
About one in 40,000 people get Wilson disease.1 It equally affects men and women. Symptoms usually appear between ages 5 to 35, but new cases have been reported in people aged 2 to 72 years.

What causes Wilson disease?
Wilson disease is caused by a buildup of copper in the body. Normally, copper from the diet is filtered out by the liver and released into bile, which flows out of the body through the gastrointestinal tract. People who have Wilson disease cannot release copper from the liver at a normal rate, due to a mutation of the ATP7B gene. When the copper storage capacity of the liver is exceeded, copper is released into the bloodstream and travels to other organs—including the brain, kidneys, and eyes.
What are the symptoms of Wilson disease?
Wilson disease first attacks the liver, the central nervous system, or both.
A buildup of copper in the liver may cause ongoing liver disease. Rarely, acute liver failure occurs; most patients develop signs and symptoms that accompany chronic liver disease, including
swelling of the liver or spleen jaundice, or yellowing of the skin and whites of the eyes
fluid buildup in the legs or abdomen a tendency to bruise easily fatigue
A buildup of copper in the central nervous system may result in neurologic symptoms, including problems with speech, swallowing, or physical coordination tremors or uncontrolled movements muscle stiffness behavioral changes.
Other signs and symptoms of Wilson disease include anemia low platelet or white blood cell count slower blood clotting, measured by a blood test high levels of amino acids, protein, uric acid, and carbohydrates in urine premature osteoporosis and arthritis Kayser-Fleischer rings result from a buildup of copper in the eyes and are the most unique sign of Wilson disease. They appear in each eye as a rusty-brown ring around the edge of the iris and in the rim of the cornea. The iris is the colored part of the eye surrounding the pupil. The cornea is the transparent outer membrane that covers the eye.
How is Wilson disease diagnosed?
Wilson disease is diagnosed through a physical examination and laboratory tests.
During the physical examination, a doctor will look for visible signs of Wilson disease. A special light called a slit lamp is used to look for Kayser-Fleischer rings in the eyes. Kayser-Fleischer rings are present in almost all people with Wilson disease who show signs of neurologic damage but are present in only 50 percent of those with signs of liver damage alone.
Laboratory tests measure the amount of copper in the blood, urine, and liver tissue. Most people with Wilson disease will have a lower than normal level of copper in the blood and a lower level of corresponding ceruloplasmin, a protein that carries copper in the bloodstream. In cases of acute liver failure caused by Wilson disease, the level of blood copper is often higher than normal. A 24-hour urine collection will show increased copper in the urine in most patients who display symptoms. A liver biopsy—a procedure that removes a small piece of liver tissue—can show if the liver is retaining too much copper. The analysis of biopsied liver tissue with a microscope detects liver damage, which often shows a pattern unique to Wilson disease.
Genetic testing may help diagnose Wilson disease in some people, particularly those with a family history of the disease.
Wilson disease can be misdiagnosed because it is rare and its symptoms are similar to those of other conditions.
Who should be screened for Wilson disease?
Anyone with unexplained liver disease or neurologic symptoms with evidence of liver disease, such as abnormal liver tests and symptoms of liver disease, should be screened for Wilson disease. People with a family history of Wilson disease, especially those with an affected sibling or parent, should also be screened. A doctor can diagnose Wilson disease before the appearance of symptoms. Early treatment can reduce or even prevent illness.
How is Wilson disease treated?
Wilson disease requires lifelong treatment to reduce and control the amount of copper in the body.
Initial therapy includes the removal of excess copper, a reduction of copper intake, and the treatment of any liver or central nervous system damage.
The drugs d-penicillamine (Cuprimine) and trientine hydrochloride (Syprine) release copper from organs into the bloodstream. Most of the copper is then filtered out by the kidneys and excreted in urine. A potential major side effect of both drugs is that neurologic symptoms can become worse—a possible result of the newly released copper becoming reabsorbed by the central nervous system. About 20 to 30 percent of patients using d-penicillamine will also initially experience other reactions to the medication, including fever, rash, and other drug-related effects on the kidneys and bone marrow. The risk of drug reaction and neurologic worsening appears to be lower with trientine hydrochloride, which should be the first choice for the treatment of all symptomatic patients.
Pregnant women should take a lower dose of d-penicillamine or trientine hydrochloride during pregnancy to reduce the risk of birth defects. A lower dose will also help reduce the risk of slower wound healing if surgical procedures are performed during childbirth.
Zinc, administered as zinc salts such as zinc acetate (Galzin), blocks the digestive tract’s absorption of copper from food. Zinc removes copper too slowly to be used alone as an initial therapy for people who already have symptoms, but it is often used in combination with d-penicillamine or trientine hydrochloride. Zinc is safe to use at full dosage during pregnancy.
Maintenance therapy begins when symptoms improve and tests show that copper has been reduced to a safe level. Maintenance therapy typically includes taking zinc and low doses of either d-penicillamine or trientine hydrochloride. Blood and urine should be monitored by a health care provider to ensure treatment is keeping copper at a safe level.
People with Wilson disease should reduce their dietary copper intake. They should not eat shellfish or liver, as these foods may contain high levels of copper. Other foods high in copper—including mushrooms, nuts, and chocolate—should be avoided during initial therapy but, in most cases, may be eaten in moderation during maintenance therapy. People with Wilson disease should have their drinking water checked for copper content and should not take multivitamins that contain copper.
If the disorder is detected early and treated effectively, people with Wilson disease can enjoy good health.
