Final answer:
Liver dysfunction, such as cirrhosis, can lead to hyperglycemia due to impaired insulin function and the liver's role in maintaining blood glucose levels.
Step-by-step explanation:
Liver dysfunction, such as cirrhosis, can lead to hyperglycemia due to impaired insulin function and the liver's role in maintaining blood glucose levels. In cirrhosis, scarring within the liver obstructs the passage of blood through the liver, causing portal hypertension and the development of shunts that bypass the liver's detoxification process. This can result in high levels of blood glucose, or hyperglycemia. Additionally, the liver's ability to produce glucose through gluconeogenesis can be affected in liver dysfunction, leading to higher blood glucose levels.
