Parasites can be difficult to find.  They can live throughout the intestines, including in the lining of the intestines.  If they are able to breed and multiply, they may leave the lining or tract of your intestines and enter into your blood stream causing more problems.

Parasites can cause tremendous problems throughout the body.

Parasites can move anywhere in the body through the blood stream, including into the organs, the hearts and the lungs.  If the parasites get into the organs, they may be difficult to find.

The digestive system has hundreds of substances enter into it each and every day that it is required to process.  It may be already compromised by some of these substances when a parasite enters into the system.  The parasites can injure digestive tissue and disrupt functioning of the digestive tract and affect the immune system.

Throughout their time in the body, parasites also can produce toxic wastes of their own, which can affect the digestive system and as far as the central nervous system.  Further, as the parasites progress to the organs or central nervous system, they become more difficult to recognize as problems and effectively treat.

As the parasites continue to remain in your body, they can continue to cause problems.  As explained above, the parasites can attach to the digestive tissues.  Once this happens, you can have chronic pain and inflammation.  This can affect absorbing of nutrients from your food.

Many times you have a parasite it can heal or be eliminated in a short period of time without any serious complications.  In the beginning stages, you may experience diarrhea, nausea, vomiting and loss of appetite.  You usually will not even have to see a physician.  If the conditions do not improve in a timely manner on their own, your physician may take a stool sample and run tests.

There are some cases when the digestive pain and problems progress.  While you are getting better, you should be concerned with dehydration.  It is important to continue to keep up with your fluid intake.  If you become dehydrated, you may need to be hospitalized for IV fluids.  Additionally, dehydration is harder on your system and can complicate your condition further.

The transmission of parasites usually targets the feces and the digestive system.  All of these systems are interrelated.  The parasites tend to migrate and breed within the intestinal system.  Therefore, almost all of the parasite infections are going to affect your digestion, your eating, your stomach and all related systems.  As usual, you should be aware of any changes in your diet or eating habits to determine if you have an infection or parasite.

If you do not feel better within a short period of time, you should always consult your physician for testing.
