Definition of Parasite & What You Need to Know About the Ones That Most Commonly Affect Humans TheWellthieone

A parasite is an organism that lives on or in another organism, known as the host, and benefits from it. Parasites can cause a variety of problems for their hosts, including disease and death. Some parasites, such as tapeworms and hookworms, live in the intestines and feed on the host’s food. Others, such as malaria-causing mosquitoes, live on the skin and suck the host’s blood. 

Still others, such as the bacteria that cause Lyme disease, live in the host’s tissue and release toxins that damage cells. While parasites are often associated with poverty and poor sanitation, they can infect anyone, anywhere. In fact, it is estimated that over half of the world’s population is infected with at least one type of parasite. In this blog post, we’ll be discussing the various types of human internal parasites like tapeworms and hookworms that you may encounter and what you can do to prevent them.

60 Million Americans Infected, Most Unaware

According to the CDC, over 60 million Americans suffer from some sort of parasitic infection. These infections are caused by tiny creatures that live off of the host’s blood or tissue.

While most parasites are harmless, some can cause serious illness. Unfortunately, diagnosing a parasitic infection can be difficult.

Testing Does Not Often Produce Conclusive Results

Many parasites are difficult to detect with conventional Western medicine testing methods, and doctors often mistake them for other conditions. As a result, many people suffer from undiagnosed parasitic infections while they are getting treated for conditions they do not have. 

A negative test for one type of parasite does not mean that you are free of all parasites.  The tests used in Western medicine often only test for one or a few types at a time, missing others. When a negative diagnosis is received, a patient may be falsely told that they are negative for all parasites, which is often not the case.

There is no harm in doing a parasitic cleanse from time to time. 

For example, if you eat sushi or any kind of raw fish, there’s a good chance you have already ingested parasites, and they’ve been living in your gut for some time.

These creatures can enter your body through contaminated food and water and set up shop in your intestines, where they can live for years. A proper cleanse is beneficial to overall health because these creatures feed on the nutrients meant for you.

If you are wondering what types of quality parasite cleansing kits are available, we have additional helpful information in this article here:

If you suspect that you may have a parasitic infection, it is important to see an integrative or more holistic doctor who is more familiar with these types of infections. With proper treatment, most parasites can be easily removed from the body.

3 Types of Common Human Parasites

There are three main types of human parasites: protozoa, helminths, and ectoparasites.

  1. Protozoa are single-celled organisms that can only be seen with a microscope. They’re usually transmitted through contaminated food or water and can cause diseases like dysentery and malaria.
  1. Helminths are multi-cellular organisms that include worms like tapeworms and pinworms. They’re usually transmitted through contact with contaminated soil or feces, and can cause diseases like trichinellosis and ascariasis.
  1. Ectoparasites are parasitic insects that live on the surface of their hosts’ bodies. They’re usually transmitted through contact with contaminated animals or humans, and can cause diseases like typhus and scabies.

There are ways to prevent parasites, including cooking food properly, avoiding raw meat and fish, washing your hands regularly, avoiding contaminated water, and wearing protective clothing when outside.


In conclusion, parasites are more common than people think and could be the reason for unexplained fatigue and illness. It is worth doing a parasite cleanse on a more regular basis.

We wish you well on your continuing journey to optimum health.
