What Causes Parasites In Humans?

Do you ever feel like there's something living inside of you, feeding off of your blood and energy? Chances are, you're not crazy - you may have parasites! Don't worry, though; there are ways to get rid of them. Keep reading to learn more about parasites in humans and how to get rid of them!

What Are Parasites?

Most people think of parasites as something that only affects animals, but the truth is that humans can be infected with them, too. Parasites are tiny organisms that live off of other creatures - including us! - for food and shelter.

There are three types of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites. Protozoa and helminths affect the gut mostly, while ectoparasites include lice and mites that attach or burrow into the skin for long periods. The majority of protozoa and helminths don't cause disease or result in mild illness only. Some, though, can cause severe human illness.

At first, the symptoms of parasitic diseases are usually gastrointestinal infections and issues like diarrhea. However, if parasites invade red blood cells or organs, they can become much more dangerous.


Protozoa are tiny single-celled organisms that multiply inside the human body. The most common type of protozoa that causes illnesses is called Giardia lamblia. These are intestinal parasites that affect the small intestine. Other types of intestinal protozoa include:

· Cryptosporidium

· Cyclospora

· Entamoeba histolytica

· Plasmodium (this is the parasite that causes malaria)


Helminths are parasitic worms that can grow up to a meter in length! The three main types of helminths that affect humans are roundworms, tapeworms, and flukes. Intestinal helminth infections usually occur when people eat contaminated food or drink contaminated water. The worms then travel to the digestive tract and attach themselves to the intestinal wall, where they can live for years. Some common helminths include:

· Ascaris lumbricoides (roundworm)

· Trichuris trichiura (whipworm)

· Taenia solium (pork tapeworm)

· Schistosoma (flukes)


Ectoparasites are parasites that live outside a human host. The most common ectoparasites that affect humans are lice and mites. Lice are wingless insects that live in clothing or on the body and feed on human blood. Mites, commonly known as human itch mite, are small arthropods that live in the skin and hair follicles and can cause scabies. Other types of ectoparasites include:

· Fleas

· Bedbugs

· Ticks

Aches And Pains Throughout The Body

Heavily Coated Tongue

If you wake up and find that your tongue is heavily coated or white, this could be a sign of an infection, which is often caused by parasites. This infection can also cause other symptoms like brain fog, fatigue, and cravings for sugar.

Intestinal Issues

Another common sign of parasites is experiencing intestinal issues like diarrhea, bloating, constipation, and gas. We know, it doesn't sound fun at all. If you also have a fever along with these symptoms, it's even more likely that parasites are to blame.

Weight Loss

If you've been trying to lose weight but haven't been able to, despite making changes to your diet and exercise routine, it could be because you have parasites. Some types of parasites can cause malnutrition by preventing your body from absorbing nutrients from food properly.

Irregular Menstruation

For women, another sign of parasites is irregular or missed periods. This is usually caused by hormonal changes that happen when parasites invade the reproductive organs.


If you have anemia, it means that your red blood cells are not able to carry enough oxygen to your tissues. This can be caused by various things, but if you also have other symptoms of parasites, it's worth getting checked out.

Ravenous for Bad Food

Parasites love sugar and processed foods. So if you find yourself constantly craving sweets or carbs even though you're trying to eat healthily, it could be because you have parasites.

Fasting has been used for centuries as a way to cleanse the body and get rid of toxins. It's believed that fasting can help get rid of parasites by starving them and cleansing your body. There are various ways you can fast, but one of the most common is to do a juice cleanse or water fast.

What is a juice cleanse? A juice cleanse is when you consume nothing but juices made from fresh fruits and vegetables for a period of time, usually 3-5 days. While a water fast is when you consume nothing but water for a period of time.

There is also another common method of fasting known as intermittent fasting, which is when you eat all your meals within a smaller window of time. For example, you would eat all your meals between 10 am and 6 pm and then fast for the remaining hours of the day.


Probiotics are live bacteria that are good for your gut health. They can help restore the balance of bacteria in your gut and improve your digestion. Probiotics are found in various foods, such as sauerkraut and kimchi.

But beware of taking synthesized probiotics or supplements, as they can do more harm than good by disturbing the natural balance of good and bad bacteria in your gut.
