12. Anxiety
Recent studies have revealed that inflammation can cause problems with anxiety and other mental issues. And because parasite infections tend to affect the nerves, the brain, the immune system, it also leaves a trail of exhaustion and fatigue in its wake. Many of these issues end up creating other problems like nervousness, sleeplessness, paranoia and simply feeling on edge. If you begin to notice feelings of unease, sadness, agitation, jitters and just not like yourself, as well as other symptoms on this list, be sure to talk to a doctor about checking for a parasite in your system.
