How Do Parasites Affect Humans?
There are many symptoms of parasites that you should be aware of. First off, know that each organism will affect the human body differently. Some parasites nourish themselves on the food that humans eat, causing weight loss, vitamin deficiencies, digestive disorders, and fatigue. Others may actually attach themselves to a point on the body (such as the liver or the intestines) and suck out their nutrition from the host itself (i.e., YOU)! Depending upon the type of parasite, infection can occur in many different areas of the body such as the lymphatic system, the intestines, or the liver. Some human parasites may continually explore the body causing damage in a number of body parts. For example, some of these harmful organisms will attach to the nerves and eat away the protein coating that is responsible for signaling the brain. Others may feed on the synovial fluid of the joints causing arthritis-like symptoms.
