Statistics from independent medical research suggests that most of the population of the post-Soviet countries is infected with helminthic invasions. More than 70% of adults and almost 95% of school and preschool children are carriers of various worms. What caused such a wide spread of parasites, and what are the dangerous worms for humans?

Worms in the human body

Worms are parasites in the human body. They feed on digestive juices or blood, and in the process of their life they release toxic substances. The harm of worms to humans is determined by the amount and composition of toxins that enter the bloodstream.

Different types of helminths secrete different toxins and live in different organs. Worms feed on split food components, so they prefer to settle in the human digestive organs, more often in the intestines. They are found in smaller quantities in the liver and stomach.

In addition, they can penetrate the bloodstream and, along with the bloodstream, enter other internal organs. Therefore, harm from worms for humans is manifested not only in diseases of the digestive system. It causes general systemic disorders and immune disruptions.

What worms are most common in the intestinal cavity, and what harm do they bring to the human body?

Types of worms and their activity

We will describe what parasites can be found in the human body during a detailed examination. And what is the peculiarity of their vital activity and the poisoning of the host's organism - a person?

Pinworms and their harm

Pinworms are intestinal parasites that look like small worms up to 12 mm long. They live in the large and small parts of the intestine and feed on its contents. Female pinworms attach to the intestinal mucosa and stay on it until the egg matures in them. All this time, they feed on split food substances. Why are pinworm worms dangerous?

In the course of their life, pinworms secrete toxic substances that cause inflammation of the intestinal walls. In medicine, this inflammation is called enterobiasis, which comes from the Latin name for pinworms - "Enterobius vermicularus" or "a worm that lives in the intestine."

With enterobiasis, the intestinal flora is disturbed. Food ceases to be fully absorbed, which makes nutrition deficient and contributes to the formation of additional toxins. The composition of feces is disturbed, diarrhea becomes frequent.

The daily intake of toxins in the blood becomes the cause of chronic poisoning. The person experiences frequent headaches, lethargy, lethargy, or irritation. The child becomes moody, does not sleep well, in a dream he often cries out, cries.

Also, the result of intoxication is various skin rashes. The body cannot cope with a large amount of ballast toxic substances, it connects the skin to their elimination. Therefore, with a long-term developed helminthiasis, a person develops an allergic reaction to food, household substances.

Violation of the intestinal flora leads to immunosuppressive conditions. The prolonged presence of parasites in the intestines greatly reduces immunity. On this basis, one can suspect that a child is infected with pinworms - frequent colds, viral diseases appear. Resistance to infections decreases, a child or an adult becomes susceptible to various diseases.

Important: studies confirm that with extensive infection with pinworms, the formation of both natural and artificial immunity is disrupted. In 20% of vaccinated children, antibodies do not form after vaccination, and in 15% they are formed in insufficient quantities.

With deep penetration of female pinworms into the intestinal mucosa, local manifestations occur. A long process leads to the formation of granulomas, anal and rectal fistulas, paraproctitis.

When they enter the appendix, pinworms can cause appendicitis. By the way, pinworms are found in a third of people operated on due to acute appendicitis.

The strong spread of pinworms in girls and women can lead to their entry into the genitals with subsequent inflammation of the mucous tissue. This is how children's vulvovaginitis appears, in adults - endometritis.

Prolonged infection with pinworms leads to constant scratching of the genitals, which in children becomes the cause of masturbation, masturbation, and early awakening of the sexual instinct.

Pinworms are the most common worms in humans. Among other helminths, they occupy a leading place, they account for up to 90% of all helminth infections.

Giardia and their harm

Giardia is a microscopic parasite. An adult is up to 0.02 mm long and shaped like a bulb with flagella. They settle in the intestines and bile ducts, while "like" stagnant bile and carbohydrate sweet foods. Note: gastric juice of normal acidity neutralizes lamblia, which can enter the digestive cavity along with raw water.

They live mainly in the upper parts of the intestines, where they feed on the carbohydrate components of split food. In the liver, they primarily "eat" unhealthy stagnant bile. What are the harmful worms such as lamblia?

Parasitism of lamblia in the intestines is accompanied by general weakness, loss of appetite, poor sleep, headaches. Giardia, like pinworms, in the process of their vital activity, release decay products - toxins. They cause local inflammation of the intestinal mucosa, disrupt its secretory function, and complicate the absorption of split food components. As a result of the activity of lamblia, feces in the upper intestines periodically stagnate.

In young children, giardiasis can cause acute diarrhea (diarrhea), similar to an intestinal infection. In older children and adults, infection with lamblia is accompanied by chronic dysbiosis, periodically there is bloating, unreasonable relief or constipation, and nausea. Chronic food indigestion causes anemia.

With prolonged infection, lamblia spreads into the bile ducts. Here they also release toxic substances that cause spasm of the bile ducts. They also interfere with the binding of bile acids, which leads to allergic rashes and itchy skin. It also initiates chronic inflammation in the bile ducts and enlargement of the liver.

In the future, lamblia toxins reduce the synthesis of immunoglobulins A, which in turn initiates the development of inflammatory diseases in the digestive organs, causing gastritis, pancreatitis.

Ascaris and their harm

Roundworms are long worms, the body of which reaches 25 cm (males) and 40 cm (females). Adults settle in the small intestine. But young larvae, just hatched from eggs, go through a difficult path, migrating through several internal organs of a person. Initially, they pass from the intestine to the liver - being absorbed through the intestinal wall into the blood.

Further along the inferior vena cava, they migrate from the liver to the heart, and then along the pulmonary artery - into the lung cavity. From here, along the respiratory tract, they rise into the pharynx and again, along with saliva, enter the stomach, and then into the intestines.

Cough is not the only harm of ascaris worms. The waste products of ascaris are strong allergens. They cause various allergic reactions - rashes, infiltrates (edema), neoplasms in the liver. In addition, during the migration of larvae, tissues are injured, small local hemorrhages and internal blood accumulations occur.

Adult worms are quite long. They live in the intestines, and, if widely distributed, can cause obstruction. In addition, the secretions of adult roundworms in the intestines form dysbiosis and intestinal upset, impair the absorption of food, cause anemia and extinguish the immune system.

Let us summarize and give a short list of diseases that form in the human body when infected with roundworms: bronchitis and pneumonia, hemoptysis, intestinal obstruction and its perforation, liver and pancreas diseases.

Solitaire or bovine tapeworm

The tapeworm is one of the longest worms, the body of which can reach 12 m. An adult tapeworm settles in the human body, which grows from a mature egg. The stage of maturation of tapeworm eggs takes place in the body of animals. Why are worms harmful to humans at sexual maturity and larval age?

The tapeworm sticks to the intestinal wall and feeds on its digestive juices. It grows and over time clogs the intestinal lumen, causing obstruction. In this state, a person urgently needs an operation, during which the presence of the parasite in the intestine is detected.

In addition, tapeworm releases toxins that disrupt the natural intestinal flora. Which leads to bowel disorders, allergic rashes and decreased immunity. Also, tapeworm toxins initiate the appearance of cystic formations on the surface of internal organs.

Because tapeworms are large in size, severe weight loss is often associated with infection with the parasite. In this case, a person feels a chronic feeling of hunger, despite the usual regimen of food intake.

The movement of the tapeworm inside the intestine triggers a response from the intestinal muscles, which is felt by the person as spontaneous movements inside. This often becomes the cause of nervousness and internal tension.

Worms in humans: why are they dangerous?

Let us summarize the information presented and draw general conclusions, at the work of which organs does helminthic invasion most often give complications?

Many worms live in the human intestine. Here they release toxins and cause dysbiosis. Which, in turn, causes several problems. Namely:

  1. Indigestion of food - causes anemia, general toxicosis, weakness;
  2. The flow of toxins causes allergic reactions, rashes;
  3. Lack of protection of friendly bacteria - reduces local and general immunity, makes the body vulnerable to infections and diseases;
  4. Violation of the intestinal flora - expressed in periodic frustration, nausea, flatulence, bloating.

Worms and nutrition

Are worms dangerous for a person who eats quality food? The likelihood of infection with helminthic infestations is greatly reduced if a person eats healthy foods. Most worms "love" sweets, so the abundance of carbohydrates in the menu increases the likelihood of infection.

But raw vegetables, fruits, salads, fermented milk products do not create "suitable" conditions in the intestines for the reproduction of pinworms, lamblia or tapeworms

A brief description of the vital activity of some parasites in the human body suggests that infection with helminths has very unpleasant consequences. It affects all human organs. It is important to understand that many modern diagnostic methods have a low probability of detecting helminthic invasions.

Therefore, it is worth carrying out periodic prophylaxis, taking funds and drugs to get rid of worms without a special examination and appropriate tests.
