**Core Concept**
The body has a limited capacity to metabolize fructose, which can lead to its accumulation in the bloodstream. This excess fructose is primarily metabolized in the liver, where it can cause an increase in uric acid production and potentially lead to an osmotic diuresis.

**Why the Correct Answer is Right**
When fructose is ingested in excess, it is primarily metabolized by the enzyme aldolase B in the liver. The metabolism of fructose leads to an increase in the production of uric acid, which is a byproduct of purine metabolism. The increase in uric acid production can lead to hyperuricemia, which is a common cause of gout.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the context of fructose overingestion. The correct answer is related to the metabolism of fructose and its effects on uric acid production.
* **Option B:** This option is not a direct consequence of fructose overingestion. While it is true that fructose can cause an increase in the production of various metabolites, the specific consequence of uric acid production is the correct answer.
* **Option C:** This option is not a direct consequence of fructose overingestion. The metabolism of fructose does not directly lead to an increase in blood sugar levels, as it is primarily metabolized in the liver.

**Clinical Pearl / High-Yield Fact**
It is essential to note that individuals with a deficiency in the enzyme aldolase B, such as those with hereditary fructose intolerance, can experience severe consequences from fructose ingestion, including hypoglycemia and seizures.

**Correct Answer:** C. Hyperuricemia.
