Which is NOT a typical cause of swelling in the body?

High blood sugar, or hyperglycemia, is not typically a direct cause of swelling in the body. Swelling, or edema, commonly results from conditions that increase fluid accumulation in tissues. Conditions such as allergic reactions, where histamines cause blood vessels to become leaky, physical injuries, which lead to inflammation and fluid movement into tissues, and circulatory issues, where inadequate blood flow and fluid regulation cause swelling, all serve as clear mechanisms for edema.

In contrast, while high blood sugar can lead to complications over time, such as diabetic neuropathy or kidney damage, which may indirectly result in swelling, it is not a typical or immediate cause of fluid accumulation in body tissues. Understanding the distinct mechanisms of each condition is crucial for recognizing how they relate to symptoms like swelling.
