  4. Decreased liver function

Option A, low blood pressure, is not directly related to bleeding risk but can cause symptoms such as dizziness and fainting. B, high sugar intake, is also not directly related to bleeding risk, although it may lead to other health issues such as diabetes which can increase the risk of bleeding.

Therefore, option C
