Which of the following are symptoms of hypoglycemia?

Hypoglycemia, or low blood sugar, presents with specific symptoms that indicate the body's response to inadequate glucose levels. The symptoms mentioned include chills, shakiness, weakness, headache, and diaphoresis (sweating). These symptoms arise as the body reacts to low glucose availability, triggering the release of adrenaline, which can lead to the classic fight-or-flight responses. Adrenaline causes shakiness and sweating, while the brain's lack of glucose can result in weakness, confusion, headache, and chills. Recognizing these symptoms is essential for prompt treatment to avoid severe complications.

The other options listed reflect symptoms more aligned with different conditions. For instance, flushed skin and increased thirst often accompany dehydration or high blood sugar (hyperglycemia) rather than hypoglycemia. Weight gain and fatigue usually indicate issues like metabolic syndrome or hypothyroidism, while nausea and vomiting can relate to gastrointestinal problems or other metabolic disorders. Understanding the correct symptoms of hypoglycemia is crucial for timely intervention and management.
