Final answer:
Untreated hypertension can lead to congestive heart failure, retinopathy, and chronic renal failure, but not typically to hepatomegaly, which is usually related to liver disorders.
Step-by-step explanation:
Untreated or unmanaged hypertension can lead to several serious health complications, but hepatomegaly (enlargement of the liver) is not typically one of them. The conditions directly related to untreated hypertension include congestive heart failure, retinopathy, and chronic renal failure. These are due to the strain that elevated blood pressure puts on the heart, eyes, and kidneys, respectively. Unlike these conditions, hepatomegaly is more commonly associated with liver disorders and is not a direct result of hypertension.
