Types of worms in humans

Worms should be understood as parasitic worms that penetrate the human body. Similar representatives exist in some species of animals.

Worms appear on the human body after being infected with parasitic eggs.

After numerous studies, scientists have concluded that more than 25 percent of people in the world know from their own experience what helminthiasis is.

As a rule, roundworms and pinworms are more common. These types of worms in humans can find a place in any of the organs.

The most favorite place for helminths is the intestines. And only then do they live in the organs of the liver and lungs.

But it is no exception when parasites find their place in the eyeball or muscles.

External characteristics of worms in humans

When diagnosing the patient's body, the doctor must have all the knowledge about the possible invasion of worms, as well as how to remove them in the future.

Thanks to this information, it is possible to avoid complex situations that can arise in the form of complications after infection with helminth eggs.

That is why it is important to identify the worms in the human body at the time of infection with them, ie in the early stages.

One of the most popular types of helminths are roundworms and worms. In appearance they resemble a white worm.

Surprisingly, their slender and elongated body can reach up to 40 cm. The average length is 20 cm.

But this does not mean that there are no parasites more compact in size. These include a wide ribbon.

It is called so for some reason, because in appearance it resembles a ribbon. Its length varies in meters.

Classification of worms

What are the types of worms in the human body? If this question really worries you, you should read the following information in the article.

The types of helminths are divided according to their position in the body. They can be tissue and lumen worms.

tissue worms

Tissue worms should be understood as those types of helminths that prefer to settle in the pancreatic parenchyma, liver, brain tissue, muscle and lung tissue.

For this reason, the pathology has many names: paragenesis in cases of lung damage, echinococcosis with abnormalities in the liver, filariasis - lymph nodes, cysticercosis in violation of the brain.

translucent worms

This type of helminth differs in that it prefers to live in the intestinal tract. These helminths include roundworms, tapeworms, whips, pinworms, hookworms, tapeworms and other worms.

Worms are also divided into species depending on their body structure. There may be round, flat, strips and other varieties. But this will be discussed in more detail later in the article.

Round view of human worms

This is a fairly common variety of helminths, called nematodes.

Their body is presented in a round shape, the length of the worms reaches up to 40 cm in most cases, but there are also 5 mm.

They choose nematodes for themselves as the location of the intestines, but they are likely to settle in tissues or other organs.

The prevalence of this type of worm is explained by the fact that eggs are transmitted when using unwashed vegetables or fruits. This type of pathology is considered a disease of dirty hands and therefore children suffer more often from round parasites, which try to get dirty hands in their mouth.

Other types of nematodes are also subdivided. There are:

Round worm

Cause ascariasis to develop. These are quite large worms, which can reach 40 cm in length.

They differ from their counterparts in the shape of the fuselage. Similar representatives are documented in the area of the small intestine.

During life, they move to the heart, liver and lungs. Carried through the human body they pose a great danger.

The point is, all organs and ducts suffer from worms. Their life cycle is about one year, but during this period a person will experience many unpleasant consequences associated with the onset of allergies, indigestion, as well as internal bleeding, obstruction of the intestinal organs.

If roundworms appear in children, this can adversely affect their development. A child may be far behind in development than his peers.

These parasites enter the child's body in the same way through unwashed hands with soap and dirty food.


Their body is gray. The length of such worms is 5-10 mm. The main location of the parasites is the intestine.

Most often, pinworms affect people who have swallowed their eggs through unwashed vegetables and / or fruits.

To become a sexually mature person, the eggs must exceed the period of 14 days. The total lifespan of the parasites is approximately equal to a few months.

They disrupt the normal functioning of the digestive system, which causes a person to become exhausted.


These worms differ in their habitat. They choose to settle mainly in the large intestine.

The worms have a body of 3-5 cm. They are placed on the walls of the organ absorbing blood. These worms cause hair loss disease, sending the body seriously.

They can exist in the human body for about 5 years. During this period, a person will have severe bowel movements, a problem with the desire to eat, i. e. there may be an increase or decrease in appetite, abdominal pain, and even anemia.

You should not leave the fact of lash infection unattended, because as part of their vital activity, the acute phase of appendicitis can begin.

This happens if the worms enter the cecum. They cause a relentless blow to health, and therefore efforts must be made to remove the lashes quickly.


Another type of worm, which is not large in size. They can grow up to 2-5 mm, but that does not mean that worms do not harm health.

They cause trichinosis, which manifests itself with high fever, edema, fever and allergic reactions.

You can catch Trikinela from undercooked pork or game meat. These worms penetrate the muscles of the airway or face, hitting the tissues.

For 3 weeks, the worm eggs can be trapped and therefore the person recovers. But there are more difficult situations that lead to death.

Another type of roundworm is the Toxocara. They are found in the dog's body. In appearance, they look like a round worm, but the body length is 15-30 cm.

This type of worm can be found in the human body. If this happens, there is a development of toxocariasis, accompanied by dysfunction of internal organs, allergic reactions and other disorders in the body.

It should be noted that the larvae, once entering the human body, are not able to develop in the state of sexually mature individuals, this is only possible in the body of dogs.

The symptoms of a worm infestation will vary depending on the state of human health as well as the number of worms in the organs.

Type of worm tape in humans

Tapeworms pose a major risk to human health. They are called cestodes. These are worms that reach 18 m. It is usually divided into 2 types:

  • ribbons;
  • chains.

To grow into sexually mature individuals, the worms must change host. One of the stages of this process is the presence in the body of cattle.

The brightest representatives of this species will be presented in a detailed description below.

wide ribbon

It reaches about 10-15 meters in length. He chooses the small intestine as his habitat.

It is able to cause the development of bifurcation. A kind of tape enters the body if a person has eaten incompletely cooked freshwater fish, which has been invaded by pest larvae.

The infection is accompanied by severe abdominal pain, indigestion, anemia. This type of worm, like many other worms, looks really awesome.

Bull movie

In length, this type of tape can reach up to 18 m. This species is one of the largest in the human body.

It causes the development of teniarinhoz pathology, which leads to physical exhaustion of the body. Also, a person may experience intestinal obstruction, dysfunctions in the central nervous system.

This type of worm enters the body through the infected beef with parasite larvae. The worm settles in the area of the small intestine, which hits all the organs of the human body.

Pork ribbon

This type of parasite enters the human body through infected pork. The worms can be up to 8 meters long.

They usually settle in the area of the intestine, where they carry out their parasitic activity.

Tension causes severe stomach dysfunction, accompanied by allergic reactions and nervous disorders.

Another dangerous type of tape is called echinococcus. Installed in the body of dogs, cats.

Humans are selected as an intermediate habitat. Even in such a short time, it can completely harm the human body, causing the development of echinococcus.

The parasite's eggs reach the larval stage. They then grow on the tissue membrane of the organs, causing the formation of cysts.

Only a surgical method can remove this manifestation of parasitic echinococci. For decades, these individuals have lived in the body of adults and experienced the process of their development into meat.

They are seals. They differ from other types of tapeworms in that they have special suction cups on the body, thanks to which they are absorbed into the walls of human organs and tissues.

They suck blood and useful information. Such worms can be as large as 1. 5 m. At first glance they look like a plant leaf.

The main source of puffiness in the human body will again be poorly cooked, poorly cooked fish or seafood.

During their developmental stages, these parasites change hosts. The main varieties of inflatables include the following subspecies:

  • fluke liver;
  • unexpected succes.

Based on the above information, it is worth concluding that almost all worms enter the human body through meat.

In fact, this is not always the case; there are also types of parasites that affect the skin. They will be discussed below.

Types of worms that affect the skin in humans

Worms called rishta can infect a person's skin and soft tissues. They cause dracunculiasis.

In length, they can reach 120 cm. Rishta hits the subcutaneous tissue or muscle tissue.

Contamination occurs when consuming untreated water. Infection can occur during the bath, because parasites enter the intestines through the fluid and then the fiber.

If the helminth reaches sexual maturity, it has the opportunity to secrete substances that have a negative effect on the human body. The skin begins to erode under the influence of it. At the site of the lesion there will be an ulcer, which the parasite uses to remove its larvae.

This phenomenon is accompanied by intense itching. Very often such phenomena are recorded in the tropics. As intermediate hosts, Indian language worms select freshwater crustaceans, i. e. Cyclops.

Upon contact with water, a person may be exposed to skin and intestinal acne. The method of infection with them is transdermal.

The parasites cause skin defects and penetrate the bloodstream. Risk factors will be cases of walking barefoot on the ground, working with soil, swimming in ponds with dirty water.

Diagnostic measures of helminthiasis and treatment

If helminth infestation is suspected in humans, the doctor recommends blood and stool tests.

In the case of a general blood test, the changes in the leukocyte count formula indicators will shift to the right. The number of eosinophils will be expressed.

Urine, sputum and the contents of the stomach, duodenum also play an important role. For this reason the doctor may prescribe scratches in the area of the anus and rectum.

After determining the type of worms in the human body, a specialist should choose the right course of treatment with drugs, along with this, effective recipes of traditional medicine can be used.

Of course, it is worth understanding that in order to avoid re-infection, it is necessary to take precautionary measures.

For the successful treatment of an infected person, it is important that the deworming process is carried out by the whole family, that simple hygiene rules are followed. It is common to repeat the course of treatment 2 weeks after the first stage of worm relief.

Folk remedies are time-tested and many people believe that they are better than the anthelmintic drugs offered by pharmacological organizations.

Their main advantage will be the absence of contraindications and side effects as such.

It is important to note that without consulting a doctor, it is impossible to start using popular traditional medicine recipes.

It is important to consider the specific type of worms, their location, and the characteristics of your body. If you make a mistake in the chosen course of treatment, the state of infection can become even more devastating.

Expert advice

  1. Treatment with folk remedies should begin with diet therapy. It is better not to eat meat, fish for a week, ie stick to a vegetarian diet. This will weaken the parasites and therefore make it a little easier to deal with the worms. It is only important to keep in mind that fasting in this case will not be a successful idea. Lack of food intake in the body will not affect the strength of the helminths, but the person will feel much worse.
  2. You should wash your hands before eating with soap.
  3. It is necessary to carry out food processing.
  4. Early detection of infection and the course of treatment are of great importance. In this case, the recovery time will be reduced to a minimum.
