Parasites in the human body

However, the world health organization gives a very dry, but the frightening figures: in the world die each year about 50 million people, with more than 16 million with their cause of death are infectious and parasitic diseases. Infestation of intestinal worms are on the third place on number of patients.

Naturally, such figures make you think about the symptoms of parasitic infestation. It is important to understand that most of the parasites exist in the human body completely asymptomatic. Quite simply said this in his book "principles of medical Parasitology" Dr. Thomas George. Brooke. He calls worms are among the oldest parasites that are well adapted to the living conditions in the intestine, so the patient does not even notice their presence.

Statistics relentless in terms of infections. Thus, each 8-9 meeting ends with the parasite infection. About this disturbing fact says a famous physician and author of medical books Zoltan Rona (Canada). He indicates that in North America due to the increasing flow of tourists and migrants ' heightened pace of pollution of water, soil, food. In addition, people are increasingly using different chemicals and antibacterial agents. This has a direct impact on the spread of worms, amoebas, nematodes among the population. Moreover, traditional medicine is not even aware of the scale of the disaster. Very common parasites in meat products, especially sausage, sausage, ham, bacon, chops, etc. infested almost all the major livestock, poultry and fish.


Who heads the Laboratory of parasitic diseases at the National Institute of Health Dr. F. Novo categorically States that in North America the number of infested people is much greater than in Africa. He also connects this fact with pollution chemicals food and water, and General deteriorating health of the nation.

Parasite – an organism that secures its existence at the expense of the owner. Parasites live in the human body, you lead your life, eat human food, and energy, and often the human cells and tissues. Recent studies indicate that the body 85% of the population of North America is home to at least one parasite. Some scholars add to this figure another 10%.

Dr. Ross Anderson made a statement regarding the fact that parasitic infestation is the most undiagnosed disease in the world. He admits that this is a very bold statement, but it is based on analysis of data from the case histories of more than 20 thousand patients and many years of experience that exceeds 20 years.

Parasites in the human body can live almost anywhere. There are no obstacles. They are parasites not only in the intestine but also in liver, joints and muscles, blood, brain, eyes. There are more than 100 species of parasites living in the human body, ranging from the invisible to the eye amoebas and ending with the worms of a few meters.

To establish that parasites in the human body is really present, by a fence of fecal analysis. This is the traditional and most common method of diagnosis. However, it is very unreliable, so as to detect the parasite only in the case when a physician assistant to see the larvae through a microscope. But not always worms lay large numbers of eggs, and therefore, during standard research, the parasite may not be expressed. Some experts recommend the triple tests, but it does not guarantee an exact result. It is believed that for the detection of parasites has to make at least 8 or even 10 research of feces.

It was found that the most common parasites that live in human intestines, are precisely the worms. They all have different shapes, may be similar to the wood sheet, bracelet for women, sharpened on both sides of the pencil. However, one thing unites them – they aim to destroy its host, to squeeze out of his body the maximum benefits. In addition, all the parasites are very prolific and viable. It is a mistake to believe that helminthic invasion is exclusively a childhood disease. Very often they suffer from adults, and most people are not even aware of such unpleasant and dangerous neighborhood.

The first signs and symptoms of parasites in human

That parasites in the human body to seek the most visible existence, is well known. However, our body is very difficult to deceive, and it sends signals to the person that was infected. The main thing is to be able to recognize these signals and to interpret them correctly.


Thus, the first signs and symptoms of parasites in humans are as follows:

Regular constipation, stasis of bile

Some parasites are able to reach large sizes, so they often become mechanical obstacle in the lumen of the intestine or in the bile ducts.

It violates the natural course of the feces and bile in their ways, forming a complete or partial obstruction. Sometimes patients even develops jaundice (e.g., roundworm).


Some parasites, in particular protozoa, in the course of their life secrete special substances which are similar to prostaglandins. This, in turn, leads to the loss of body sodium and chloride, which provokes the development of diarrhea.

Flatulence, bloating

If the parasites a place of residence choose the small intestine, it causes a characteristic discomfort in the form of copious gases.

In addition, intestinal inflammation contributes to poor assimilation of nutrients. Fats, which normally had to be processed in the small intestine, enter with it into the colon, causing her cramps, alternating diarrhea and constipation.

Joint and muscle pain

Parasites in humans get freedom of movement. They will settle in places where they are most comfortable conditions of existence. This place is often the joint fluid or muscle.

As a result, they either injure joints, or provoke the body's immune response that begins to attack its own joints and muscle tissue that leads to inflammation and pain.

Allergic reactions

Parasites injure the intestinal lining. In the damaged areas of the mucosa can get food, which leads to inflammation to which the body reacts to increased level of eosinophils.

It is the eosinophils are directly involved in allergic reactions. In addition, they enhances the production of immunoglobulin E. the organism also reproduces in large numbers in response to parasitic invasion.

Skin problems


Parasites in the human body, inhabiting the gut, often provoke atopic dermatitis, eczema, urticaria. Giardia, in turn, are responsible for inflammatory skin reactions. The lack of nutrients and vitamins causes the skin becomes dry, dull and prone to acne.

Trouble sleeping, nervousness

This is due to irritation CNS toxic products that produce the parasites. In addition, some species of parasites can live in the brain and to influence it from the inside.

Teeth grinding in sleep

Often this symptom is alarming parents whose children according to the diagnosis results are infested with parasites. The relationship of bruxism and parasites in traditional medicine still remains unknown.

However, scientists believe that teeth grinding at night is associated with irritant substances secreted by the parasites on the human nervous system.

Chronic fatigue syndrome

Chronic fatigue syndrome with weakness, drowsiness in the daytime, with the deterioration of all cognitive abilities. The cause of this condition are often is parasites.

A weakened immune system, frequent colds, acute respiratory infections, chronic adenoids, tonsillitis

The immune system weakens, decreases the production of immunoglobulins, designed to deal with the attacks of viruses and bacteria. As a result the person usually begins to ache.

An additional factor that reduces immune defenses, are persistent toxic and allergic reactions, which occur due to parasitic activity of the worms.

The development of cancer

It is established that the risks of oncological diseases increase because of lack of nutrients, prolonged and sluggish inflammatory process in the tissues of an organ. The perpetrators of these pathological conditions are often be parasites.

If a person observes himself or his relative a few of these symptoms, it makes sense to be screened for the presence of helminths in the body.

The above symptoms of parasitic infestation is not all signs that can indicate the presence of parasites in the body. They can be supplemented and modified depending on what kind of alien organism lives in the human body.

Next, consider the symptoms of parasites, depending on their type:


Symptoms of enterobiasis (pinworms).Pinworms cause worms, called pinworms. These are the most common parasites in the human body. The people they are better known as worms.

Symptoms of worm infestation:

  • Anal itching, which is most pronounced in the evening hours and during night rest. It is due to the migration of female pinworms to the rectum and the process of laying eggs in the perianal folds.
  • Local redness and scratching of the skin may eczema in the anal area.
  • The intense itching provokes sleep disturbances, bruxism, lethargy, drowsiness, fatigue. In children, possible urinary incontinence.
  • Periodically there are abdominal pain, cramping which are of the nature of low intensity. Mainly localized pain in the right iliac region.
  • Appetite often worsens, the stool becomes unstable, possibly alternating constipation and diarrhea.
  • Man worried about flatulence, nausea, sometimes vomiting may occur.
  • Allergic manifestations enterobioza more vulnerable children. Reactions proceed according to the type of atopic dermatitis, allergic conjunctivitis, bronchial asthma.
  • Occasional headaches, memory loss, deterioration of attention, increased irritability.

Symptoms of enterobiasis will vary depending on the age of the person and the massiveness of invasion. In some instances, pinworms can lead to serious health problems, including appendicitis, urethritis, cystitis, proctitis, vulvitis, etc.


Symptoms of teniasis (pork tapeworm).Tapeworm is a parasitic infestation that is caused by lesions of the small intestinal pork tapeworm.

Symptoms of teniasis can be hidden, and can be clearly expressed:

  • Early patient's complaints boil down to the fact that he had nausea, vomiting, diarrhea or constipation, weight loss and appetite.
  • If person vomits, the vomit, the possible presence of segments of the pork tapeworm larvae inside.
  • Are weak pain in the abdomen, although sometimes they can leak type contractions.
  • Possible anal itching.
  • Frequent dizziness, headaches, quality of sleep, possible fainting.

In 60% of cases of cerebral cysticercosis observed when the larvae of the worm into the cerebral hemispheres. The person begins to suffer from speech defects may develop epilepsy, headaches, mental disorders, delusions, hallucinations, fainting. In addition, parasites in the human body is able to penetrate into the eye, the heart, lungs, can parasitize the skin.

Alveolar dangerous because it can metastasize to the brain. In this case, the person has common symptoms with severe pain, attack, etc. can Not be excluded fatal disease.

The symptoms of giardiasis (Giardia).Giardiasis is a protozoal parasite, which provoked intestinal Giardia. Asymptomatic carriage occurs in 25% of cases.

For other cases typical clinical picture:

  • Disruption of the functioning of the gastrointestinal tract.
  • Complaints of pain around the navel and the right hypochondrium.
  • Characterized by nausea, belching, poor appetite, bloating.
  • The chair is often frothy, may happen up to 5 times a day. Diarrhea alternate with constipation.
  • Once acute form of the disease has passed, infection becomes subacute course. Man begins to lose in weight, occasionally bothering his intestinal symptoms.
  • The heavier the infestation, the more symptoms of intoxication. The prolonged increase in body temperature to levels, CNS depression (irritability, fatigue, decreased performance, weakness, nervousness, mood swings).
  • Giardiasis in children is often expressed in the form of urticaria, the appearance of ticks, unconscious state, pruritus.

Symptoms of parasites in humans myriad. The severity of manifestations depends, first of all, the immune status of the patient and from which the parasite entered the body, and where it is a parasite.
