The main signs of the presence of parasites in the human body. Symptoms of parasites

According to who statistics, about 95% of the population are infected by parasites –microorganisms that exist at the expense of other organisms.

Types of parasites that often affect the human body


Worms is the common name of the worms that exist in a living organism. To put it simply, worms. Their klassificeret for the following types: tapeworms (custodia), flukes (trematodes) and roundworms (nematodes).

The most common type of worms are round worms. Among them are: Ascaris, pinworms, Trichinella, Toxocara, whipworm, hookworm. They are round and mostly live in the intestines, its various departments. Some representatives, for example, Trichinella, can migrate throughout the body.

The intestine is the main place for the life of roundworms

Representatives of the band pests – bovine and porcine cepni, broad tapeworm, Echinococcus. The size of the parasites can reach several meters in length. Some of them begin to grow outside the human body. Bovine and porcine cepni, for example, penetrate the intestine at an intermediate stage.

Flukes can be located in various organs. Eat blood cells, also may use intestinal contents, mucus, etc. Their length is up to half a meter. This includes liver and cat Fluke, shistosoma, etc.

According to the type of development helminths are divided into biohelminth, and contact geohelminth parasites. Biohelminth undergo a stage of maturation and development in animals. This, for example, Toxocara, bovine and porcine cepni etc.

Geohelminth develop in the soil. And get inside the person through the skin or by ingestion. These include many species of roundworms.

Contact the parasites penetrate human by direct contact with another person. Enterobiasis is one of the diseases that is transmitted by contact with parasites pinworms.

How is the infection

To become infected with the larvae of parasites by eating raw food (fish, Cape), poorly washed raw vegetables and fruits, when insects bite, during intercourse, everyday way of eating raw water and swallowing water while swimming in pools, Pets across the soil.

Flies also are vectors. They carry on their paws parasite eggs, which then fall inside people together with products. Contaminated localities, the hot climate, unsanitary conditions, violation of rules of personal hygiene increases the chance of infection.

Common signs of the presence of worms

The worm

Very often recognize the presence of the considered pests in the body of the individual is difficult. And many of the symptoms can be mistaken for chronic disease and unsuccessfully treated it.

Symptoms may vary depending on the species of worms, their localisation and quantity. But there are General signs of the presence of parasites in the human body.


As a result of metabolic processes of the worms secrete toxic elements which penetrate into the blood system and contribute to the allergic manifestations.

The rash may intermittently appear and disappear. Such an Allergy is difficult to treat dermatological preparations.

Troubled skin

Infected worms may be manifested by dryness of the skin, a variety of inflammation in acne, pimples, boils.

Syndrome gastric and intestinal discomfort

Many parasites inhabit the large and small intestine of the individual. They stick to the walls, annoy them and contribute to the emergence of inflammatory processes in the organs. Disturbed function of absorption of nutrients, especially fat.

There are inherent symptoms of "irritable bowel syndrome"

A large number of fatty elements in the stool can be detected by laboratory methods.

Bile stasis

Because of its enormous size, some parasites can block bile ducts and cause biliary dyskinesia. These symptoms can provoke other more serious liver disease.


Worms may block the lumen of the intestine. Often the signs of parasites in humans manifest with symptoms such as constipation, and can even lead to intestinal obstruction.


Diarrhea is one of the most common symptoms of helminth infection. Prostaglandins, which are produced by parasites, leads to frequent watery stools.


Because of the violation of bowel function, there are symptoms such as diarrhea, constipation, excessive gas, which mistakenly can be taken for dysbiosis. But in this case the treatment with antibiotics and probiotics does not give positive results.

Reduced immunity

Parasites eat what man eats. They absorb a large part of the digested nutrients.

Because of the constant response of the immune system to the presence of "foreign residents" reduce the defenses organisms that weakens the immune system. This is manifested by frequent colds, unreasonable fever, pain in the body etc.

Pain in joints and muscles

Worms can affect different organs. Trichinella, for example, settle in the muscle and may damage it.

Symptoms of arthritis

It is the body's response to the parasite viability.

The change in body weight

One of the signs of helminthiasis is the reduction of body weight or obesity. The weight loss is due to the inability to obtain nutrients from the food consumed. And weight gain as a result of the reaction of the body, the need to "stock up on food for the future".

Therefore, before taking the decision to set or reset weight it is necessary for a complete examination for the presence of parasites in the human body.


Some parasites, Trichomonas, for example, can affect various human organs, including blood. Feeding her cells, helminths provokes anemia and iron deficiency.


The person experiences a lack of nutrients and vitamins, causing a deficiency. This is a consequence of the extravagance of parasites.

Nervousness, sleep disturbance

Insomnia, poor short sleep may be a nervous system response to the presence of "illegal" residents. Some worms at night come out through the anus in order to lay their larvae.

This could cause the discomfort and itching that causes you to Wake up frequently and does not allow relaxation.

"Chronic fatigue syndrome"

Against the background of General intoxication, lack of vitamins and nutrients that are absorbed by the parasites, the individual may feel constant fatigue, poor concentration, apathy and memory impairment.


The presence of parasites is not the best influence on the human body as a whole. Disrupted the normal functioning of all the organs which arise from inflammation, deteriorating health, reduced immunity.

It is important to know that all of these symptoms, if prolonged activity can cause the formation of tumors and cancer.

Specific symptoms of infestation


In addition to General, there are a number of special signs of the presence of parasites in the human body, which are inherent to women and men separately.

For women it is:

  • violation of the regular cycle of menstruation;
  • vaginal dysbiosis, fungal infections;
  • inflammation of the ovaries, kidney, bladder;
  • uterine fibroids;
  • infertility.

For men consider the disease manifests itself:

  • sexual dysfunction;
  • the presence of sand or stones in kidneys, bladder;
  • inflammation of the prostate gland;
  • mental disorders.

Differences in the characteristics of children and adults

When ingested the larvae of parasites, they are faced with a protective barrier:

  • saliva;
  • gastric juice;
  • local immunity of the intestine.

In the child's body, this protection may not work. And it is the children most affected by this disease. In the summer, when kids are on the street, the risk of Contracting worms is very high.

Tract infection for children is more than enough: a children's sandpit, Pets are not always washed fruits and vegetables, bathing in the ponds. Plus, especially for the little ones, the desire to taste. Habit of sucking fingers only adds to the likelihood of catching helminthic infestation.

The most frequent types of parasites in children include: pinworms, ascarids, whipworm, Toxocara.

Pinworms – small white worms, no larger than 1 cm They come out and lay their eggs around the anus. Therefore, the presence of such parasites is always accompanied by itching around the anus. Roundworm – larger sizes, their length can reach 40 cm!

When worm infestation in children, first of all, there are such symptoms as lack of appetite, pale skin, decrease in body mass. Lag in mental and physical development, memory disorder can also indicate the presence of parasites.

Live worms provoke metabolic disorders, reduced immunity in the child. All this is manifested in frequent viral infections, allergic reactions.

The cause of atopic dermatitis in children may be the presence of worms

Please note that such a phenomenon as "bruxism" (teeth grinding) is one of the signs of the presence of parasites in the human body and often troubled children in their sleep. Parents should pay attention to this fact, and to survey the child on presence of parasites.

Very often, worms live in the intestines, so the children may experience problems with the chair, flatulence, vomiting, epigastric pain.

Diagnosis of parasites

The main problem in the diagnosis of parasitic diseases is that they are disguised as a chronic illness and very difficult to recognize the real cause of the symptoms.

Also significant problem is posed by the ability of many parasites to long, sometimes existence without symptoms in the human body. Therefore, if there are signs of a chronic disease, should be examined for the presence of parasites.

Methods of diagnosis of parasites:

  • Direct methods: stool, urine, scrape of perianal region, unguinal phalanges, sputum and duodenal contents.

These methods have several disadvantages that are associated with the period of parasite development, and also with the condition of the human body.

To increase the informative value of such a diagnosis, it is necessary to undergo examination several times. But that does not guarantee the receipt of reliable information.

  • Recently used a stool sample according to the method of PCR, greatly increasing the efficiency of direct methods, as it helps to calculate the parasites of their DNA. But it is only in the case of the presence of parasites in the digestive tract.
  • Indirect methods: x-ray, morphological, ultrasound, biopsy.
  • Bioresonance methods: the method of Voll, VRT.

The method of enzyme immunoassay is to determine the presence of antibodies to parasites of various kinds in human blood. This method is very informative and helps to identify early forms of disease.

If you need to go to the doctor

In the initial stages, the signs of the presence of parasites in the human body may be missing. It will take years before a parasitic infestation to manifest itself.

It is important to remember that, if a person is concerned about any of the symptoms described above should immediately consult a specialist, especially if it concerns children. The doctor will prescribe tests that might need to go a few times for more accurate information. Then will have to choose an adequate treatment.

Helminthiasis is a very serious and dangerous disease. It is important to remember this and will not allow the parasite to inflict severe harm to the body. So you should observe good personal hygiene, follow food and promptly seek help from a qualified specialist.
