4. Weakness

Fatigue is a common symptom of many illnesses, and it can range from mild tiredness to extreme exhaustion depending on the cause. During an infection, the body releases hormones called cytokines that signal your cells to conserve energy, resulting in feelings of weakness. The fatigue associated with blood poisoning is much more intense than everyday tiredness, often making even simple tasks feel overwhelming.
