Low copper levels in the blood may be associated with picky eating and reduced liver function such as hepatomegaly. Usually, no special copper supplements are needed, but you can avoid picky eating and eat more meat and dried fruits. You can also take medication as prescribed by your doctor. 1. Low blood copper caused by picky eating: Low blood copper can be treated by adjusting the diet. Since the human body does not store copper, it must take in copper from food every day to make up for the copper that is excreted. Patients can eat more meat, dried fruits, animal offal, etc. Do not be picky about what you eat. 2. Low blood copper caused by hepatic dysfunction: human serum copper is mainly combined with globulin produced by the liver, so the presence of hepatic dysfunction, such as hepatomegaly will lead to low serum copper. At this time, can follow the doctor’s instructions for drug treatment, such as the use of D-penicillamine and so on. Patients with low serum copper should be diagnosed by a professional doctor to determine the cause of the disease, do not blindly supplement copper or medication, in order to avoid adverse consequences.
