5. Confusion
When the body is faced with any kind of severe infection that it can’t get rid of, it can sometimes choose to put even more energy towards trying to get rid of the offender in the system – which can be a parasite like Giardia in many diagnosed cases. While the body is doing this, you have to realize that it’s going to take energy away from another part of the body to compensate for this energy loss – and this can lead to many other symptoms that one might not associate with giardia or other parasite infections, but ones that will almost always show up.
Confusion can be a common symptom associated with parasitic infections. In some cases it can happen due to the energy process and the body’s attempt to expel the parasite as described above, but in more severe cases it can be confusing due to the parasites traveling up where they can affect the brain and spinal column.
See your doctor if any confusion becomes a symptom regardless of the other symptoms you experience in conjunction.
