Certain diseases can impair the functioning of the liver.

They include:
1. Diabetes mellitus: This disease is caused as a result of the inability of the liver cells to convert excess glucose in the blood to glycogen. This is as a result of the failure of the pancreas to produce a hormone called insulin. Consequently, excess sugar is left in the blood and lost through urine.
