Fanconi syndrome is a rare disease of the kidneys that causes the excessive elimination of glucose, bicarbonate, potassium, phosphates and certain amino acids in the urine. In this disease there is also loss of protein in the urine and the urine may smell stronger and more acidic.
Hereditary Fanconi syndrome is caused by genetic changes that are passed on from father to son.In more rare cases, Fanconi syndrome can be acquired, that is, it can appear in people who did not have the syndrome, mainly due to the ingestion of heavy metals, ingestion of expired antibiotics or due to some health problems, such as vitamin D deficiency, kidney transplantation, multiple myeloma or amyloidosis.
This syndrome has no cure and its treatment consists mainly of replacing the substances lost in the urine.
