According to unofficial estimates, both in the United States and in Russia, the level of infection of the population with parasites is 95-99%, and most are not even aware of this. Helminths (worms) are among the most common parasites.

Contrary to popular belief, they live not only in the intestines, but also in many other organs of the human body, up to the brain and skin, and can cause allergies, respiratory diseases and others, which even doctors do not always associate with helminthiasis.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

What parasites do people most often get sick?

Statistics show that, as a rule, certain types of parasites predominate in certain regions. For example, parasites found in tropical countries are rarely diagnosed in people living in more northern regions.

In Europe and the CIS countries, about 20 types of parasites are most often found, including:

Nematodes (roundworms):

  • Pinworm;
  • Ascaris;
  • Vlasoglav;
  • Trichinella;
  • Negator americanus;
  • Trichostrongylides;
  • Intestinal acne;
  • Ankylostomida.

  • Cat fluke;
  • Liver fluke;
  • Nanophyetus schikhobalowi;
  • Metagonimus yokogawai.

Symptoms if parasites are in the stomach or intestines

Signs that intestinal worms live in the body are often similar to symptoms of other diseases that can be caused by a completely different cause. There are a lot of signs by which one can suspect intestinal infection with worms, and they are quite diverse.

The main symptoms of parasites in the stomach and intestines:

  • Diarrhea due to the destruction of the intestinal microflora by the parasite and damage to the intestinal walls;
  • Constipation due to impaired intestinal motility;
  • Flatulence (increased gas production);
  • Decrease in body weight due to lack of appetite and impaired absorption of food;
  • Impaired absorption of nutrients and trace elements due to the fact that they are utilized by worms;
  • Belching, unpleasant taste in the mouth 2-3 hours after eating;
  • Nausea and vomiting when overeating due to the fact that the weakened stomach and intestines cannot take in excess food;
  • Pain in the liver and intestines, which are worse after exercise, stress or heavy drinking;
  • Sudden acute attacks of intestinal colic due to paralysis of certain segments of the gastrointestinal tract by helminths, which leads to peristaltic contraction of the intestine.

Other symptoms:

  • Allergic reactions to the parasites themselves and to their metabolic products;
  • Decreased work of the immune system;
  • Poor skin condition;
  • Anemia;
  • Insomnia;
  • Irritability and nervousness;
  • Chronic fatigue syndrome;
  • Respiratory problems.

The manifestation of worms with damage to the nervous system and brain

The parasites found in the brain include cysticercus and echinococcus.

Cysticercosis is a parasitic disease of the nervous system that occurs when pork tapeworm eggs (pork tapeworm) enter the human gastrointestinal tract.

For the development of cysticercosis, it is necessary for the eggs of the helminth to enter the stomach and intestines, where, under the influence of gastric juice, the dense shell of the eggs dissolves, and the released embryos are carried through the blood vessels through the tissues and organs of a person. Most often (more than 60%), cysticercus enters the brain, less often skeletal muscles and eyes. Life expectancy in the brain is from 5 to 30 years.

On the inner surface of the bubble there is a Finnish head - a scolex with hooks and suction cups.

Cysticercus is localized in the pia mater at the base of the brain, in the superficial parts of the cortex, in the cavity of the ventricles, where they can swim freely. When the parasite dies, it calcifies, but remains in the brain and maintains a chronic inflammatory process.

Cysticercosis has a toxic effect on the nervous system and causes reactive inflammation of the surrounding brain tissue and membranes. Cysticercosis is accompanied by cerebral edema and hydrocephalus. For cysticercosis, various mental changes are typical. They are expressed by neurotic manifestations, and in more severe cases - in agitation, depression, hallucinatory-delusional phenomena, Korsakov's syndrome.

CSF hypertension and cerebral edema are manifested by paroxysmal intense headache, vomiting, dizziness, and congestive optic discs.

With the localization of the cysticercus in the ventricle, Bruns syndrome occurs, consisting in paroxysmal sharp headache, vomiting, forced position of the head, respiratory distress and cardiac activity, sometimes impaired consciousness.

Echinococcosis is caused by the echinococcus tapeworm larvae. Symptoms of infection with echinococcus in the early stages are mild and intensify with the course of the disease. The latency period can last for many years, and manifestations of increased fatigue and headaches are attributed to age.

Localized in the brain, the larva forms a bubble around itself - the so-called fibrous capsule. The fibrous capsule affects the organ in which the echinococcus larva has settled, by growing and, accordingly, squeezing the tissues of the organ.


The result of the vital activity of most helminths is toxic substances that cause the phenomenon of general intoxication of the body.

The constant exposure to toxic substances on the body leads to the formation of persistent disorders of the central nervous system:

  • Headache of varying intensity;
  • Dizziness;
  • Feeling of nausea, sometimes vomiting;
  • Increase in body temperature up to fever;
  • Pain in large and small joints;
  • Avitaminosis, which is a constant companion of helminthiasis, in combination with toxic effects on the nervous system leads to the formation of chronic fatigue syndrome, loss of concentration, as well as increased drowsiness or insomnia.

Can allergies be a sign of worms in the body?

Any allergic reaction in the human body manifests itself in the form of a retaliatory strike by the immune system. This is the detection of antibodies against foreign organisms. Worms are one of the most active producers of antibodies that can cause allergies.

The reasons for such manifestations can be different:

  • The body's reaction to the waste products of the worms that they secrete;
  • Decomposition of dead parasites;
  • Soft tissue damage caused by worms when moving.

The first symptoms of allergy with worms may appear already in the presence of larvae in the human body. In the course of their life, worms need to absorb many trace elements.

They suck zinc, manganese, silicon, etc. from the human body. Lack of these elements leads to a deficiency in the production of enzymes in the gastrointestinal tract.

Lack of essential enzymes provoke the fact that food stops being absorbed. It is at this moment that allergic manifestations appear.

Most often it is a rash on the skin, itching. Here are the most common allergic reactions caused by worms:

  • Echinococcus, roundworm, toxocaras can cause allergies throughout the entire period of being in the human body. The reaction manifests itself not only in a rash on the skin, but also in edema, both external and internal. All organs and mucous membranes, to which the larvae have attached, swell;
  • Pinworms manifest themselves at night. The patient is worried about itching in the anus, provoked by the laying of eggs by the female parasite, which crawls out for this. In addition to itching, there may be a small rash on the body;
  • Ascaris infection is expressed by a rash on the skin and the manifestation of conjunctivitis.
  • Trichinella causes swelling and rashes all over the body, fever, general malaise;
  • The feline fluke will manifest itself in the form of urticaria;
  • Intestinal acne causes an allergic cough;
  • Anisakides can cause anaphylactic shock.

Symptoms of parasites in the lungs

The larvae of worms can live in the lungs, without showing themselves, for many years. The manifestation of helminths and the appearance of symptoms begins no earlier than 3-4 years later with chest pains.

Then, developing, the worms in the lungs begin to multiply, secrete waste products and the person has shortness of breath and cough. Most often, even doctors confuse these signs of a person with worms in the lungs with symptoms of bronchitis or pneumonia.

You can suspect the appearance of parasites in the lungs by the following signs:

  • Decreased appetite;
  • General weakness of the body;
  • Frequent attacks of nausea, vomiting;
  • Severe pain in the chest area;
  • Feeling better in the evening than in the morning;
  • A sharp jump in temperature;
  • Migraine headaches, dizziness;
  • Morning cough with little sputum;
  • A persistent allergic reaction caused by the waste products of parasites.

Symptoms of worms with heart disease

Dirofilariae, schistosomes, filariae, echinococcus - all these worms can parasitize in the human body, and their larvae can enter the bloodstream and heart.

The following symptoms indicate the presence of helminths in the heart:

  • Headaches occur against the background of intoxication of the body;
  • The body responds to foreign invasion with allergies. A rash appears on the skin that looks like hives;
  • Often the patient is worried about nausea, in some cases vomiting occurs, not associated with food intake;
  • Pain and heaviness in the heart, which many patients associate with heart disease. Therefore, they are treated by a cardiologist, or they themselves drink cardiovascular drugs in the hope that everything will return to normal. Shortness of breath and chest pain appear;
  • Helminthic invasion leads to rapid weight loss. In this case, the appetite may be normal or even increased;
  • The body temperature rises periodically, which is associated with the phase of migration of helminths in the body;
  • Constant fatigue and lack of sleep leads to irritability and unreasonable aggression.

Manifestations of helminthiasis under the skin

Parasites can also infect the skin, invading the layers of the skin. This is manifested by a number of specific signs inherent in each type of parasite, which causes not only discomfort in the patient, but also serious complications, including the formation of abscesses, which are sometimes worse than helminthiasis itself.

Worms living under the skin of a person create not only unpleasant, but also very dangerous diseases:

  • Cysticercosis: manifests as a rounded mass on the shoulders, palms, or chest that becomes denser over time. Allergic rashes often occur on the patient's skin, facilitating the diagnosis of this disease;
  • Dirofilariasis: occurs after the bite of an infected insect, usually a mosquito. The disease is manifested by the appearance of a painful nodule or even a feeling of worming. Parasites destroy the surrounding tissues and lead to intoxication of the body;
  • Gnatostomiasis: occurs when eating meat from an infected animal that has not been properly heat-treated. Helminths cause swelling of the skin in a person, as well as damage to the eyes and even internal organs;
  • Dracunculiasis: a dangerous infection that can even cause death. Blisters form on the skin, which burst on contact with water.


Blood poisoning

Some types of helminths directly reproduce and live in blood vessels, and some maintain their vital activity by feeding on human blood.

Parasitic individuals, the main source of food for which is blood, not only provoke the development of diseases of internal organs, but can also lead to death.

Among the most common individuals in the blood are:

  • Hemosporidia;
  • Trypanosomes;
  • Microfilariae.

The danger of this type of parasite lies in their rapid reproduction and colonization. Signs of worms in human blood include:

  • General intoxication of the body, its weakening;
  • Periodic temperature rise up to 37.5 ° C;
  • An allergic reaction is a rash on the body that suddenly appears and also disappears, not being treated with dermatological drugs. In allergy sufferers, the reaction can turn into an attack of bronchospasm;
  • Anemia is a lack of vitamins and minerals in the human body, which leads to pallor of the skin and frequent dizziness;
  • Nervousness and fatigue, apathy, memory impairment;
  • Decreased immunity - frequent colds and allergies, the penetration of infections into the human body, the possibility of oncology development against the background of constant poisoning by the waste products of parasites;
  • Asthma - as the worms move throughout the body, the airways are touched, phlegm is released, a runny nose appears and the temperature rises.
