Parasites in the human body

However, the world health organization provides a very dry, but frightening figures: in the world die each year about 50 million people, more than 16 million of them the cause of death are infectious and parasitic diseases. Infestation of intestinal worms are in third place in the 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 are in the human body completely asymptomatic. Simply said this in his book "principles of medical Parasitology" Dr. Thomas George. Brooke. He calls worms are among the oldest parasites of man, which are perfectly adapted to life 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 of the parasite infection. This disturbing thing, said the famous doctor and writer of medical books Zoltan Ron (Canada). He shows that in North America due to the increasing flow of tourists and immigrants increased the rate of pollution of water, soil, food. In addition, people are increasingly using a variety of chemicals and antibacterial agents. This has a direct impact on the spread of worms, amoebas, nematodes among the population. In addition, traditional medicine is not even aware that the scale of the disaster. A very common parasite in meat products, especially sausages, sausages, ham, bacon, chops, etc. Parasites infected nearly all major livestock, poultry and fish.


The head of the laboratory of parasitic diseases National Institute of Health, Dr. F. Nova categorically States that in North America the number of infested people is much higher than in Africa. He also connected this to the fact, 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 living in the human body, to live and work, eat people food, and energy, and the number of human cells and tissues. Recent studies show that the body 85% of the population of North America is home to at least one of the parasites. Some scholars add to this figure another 10%.

Dr. Ross Andersen made a public statement to the fact that parasitic infestation is the most undiagnosed disease in the world. He admits that he is a very bold statement, but it is based on the information collected, the analysis of the case histories of more than 20 thousand patients and many years of experience, which exceeds 20 years.

Parasites in the human body can live almost anywhere. For them there are no obstacles. They are parasites not only in the intestine but also the 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 confirm that parasites in the human body is really present, fence the fecal analysis. This is the traditional and most common method of diagnosis. However, it is very unreliable, because you can detect parasites only, if the physician assistant will see the larvae through a microscope. But not always worms lay large number of eggs, and therefore, during standard research, parasites can not be detected. Some experts recommend the triple tests, but it does not guarantee to get the result. It is believed that the detection of the parasite is to make at least 8 or even 10 research of feces.

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

The first signs and symptoms of parasites in humans

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


So, the first signs and symptoms of parasites in humans are the following:

Regular constipation, biliary stasis

Some parasites can achieve impressive size, so they often become mechanical obstruction in the gut lumen or the bile ducts.

It violates the natural feces, and bile of their ways, to form complete or partial blockage. Sometimes patients even develop jaundice (e. g., roundworm).


Some parasites, in particular protozoa, 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 parasite a place for homeowners to choose from in the small intestine, it causes a characteristic pain in the form of abundant gas.

In addition, intestinal inflammation contribute to poor assimilation of nutrients. Fats, which normally should be dealt with in the small intestine, drop it into the colon, causing her cramps, alternating diarrhea and constipation.

Joint and muscle pain

Parasites in the human body's free movement. They will settle in places where they are most comfortable conditions of existence. This place is often a common liquid or meat.

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

Allergic reactions

The parasites damage the intestinal mucosa. In the damaged areas of the mucous membrane of the can to get food, which leads to inflammation, which the body responds with increased number of eosinophils.

It is the eosinophils are directly involved in allergic reactions. In addition to strengthening them to promote the production of immunoglobulin E. the organism also produced in large quantities in response to parasitic attack.

Skin problems


Parasites in the human body, which live in the gut, often cause atopic dermatitis, eczema, urticaria. Giardia, in turn, are responsible for the skin's inflammatory reactions. Lack of nutrients and vitamins causes the skin to become dry, dull and prone to acne.

Trouble sleeping, nervousness

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

Teeth grinding sleep

Often this symptom is alarming parents whose children according to the diagnosis results are the parasites. Relationship between bruxism and parasites traditional medicine is still unknown.

However, the researchers believe that teeth grinding at night is associated with irritating substances excreted by the parasite in the human nervous system.

Chronic fatigue syndrome

Chronic fatigue syndrome weakness, drowsiness during the day, with the deterioration of all cognitive abilities. The reason for this condition often are just parasites.

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

The immune system weakens, reduces the production of immunoglobulins, the purpose of which is to deal with the attacks of viruses and bacteria. The result is usually a person begins to ache.

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

The development of cancer

It is reported that the risk of oncological diseases to increase, because lack of nutrients, long-term and slow the inflammatory process in the tissues of the organ. The factors of these pathological conditions are often parasites.

If a person finds himself or his relative a few of these symptoms, it is sensible to be screened for the presence of helminths in the body.

The above mentioned symptoms of parasitic infestation is not all signs that may indicate parasites in the body. They can be supplemented and changed depending on what kind of alien organism living 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. People, they are known as intestinal worms.

Symptoms of worm infestation:

  • Anal itching that is most intense 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 anus of the folds.
  • Local redness and scratching of the skin can rash in the anal area.
  • The intense itching provokes sleep disturbances, bruxism, somnolence, drowsiness, fatigue. In children, possible urinary incontinence.
  • At times there is abdominal pain, cramping, which are by nature low intensity. Mainly localized pain in the right iliac region.
  • Appetite often worsens, the stool becomes unstable, possibly alternating between constipation and diarrhea.
  • A man worried about flatulence, nausea, sometimes vomiting may occur.
  • Allergic reactions enterobioza more vulnerable children. The reactions proceed according to the type of atopic dermatitis, allergic conjunctivitis, asthma.
  • Occasional headaches, memory loss, deterioration of attention, increased irritability.

Symptoms enterobiasis vary depending on the age of the person and the massiveness of the attack. In some instances, pinworms can cause serious health problems, such as appendicitis, urethritis, cystitis, proctitis, vulvitis, etc.


Symptoms of teniasis (pork tapeworm).The tapeworm is a parasitic infestation that has caused damage in the small intestine of the pork tapeworm.

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

  • Early patient complaints boil down to the fact that he had nausea, vomiting, diarrhea or constipation, weight loss and appetite.
  • When a person vomits, the vomit, the possible presence of segments of the pork tapeworm larvae inside.
  • Appear weak abdominal pain, although sometimes they can leak the type of contractions.
  • Possible anal itching.
  • Often dizziness, headache, sleep quality, possible fainting.

60% of cases of cerebral cysticercosis observed when the larvae of a worm brain. A person begins to suffer from speech defects may develop epilepsy, headache, mental disorders, delusions, hallucinations, fainting. In addition, parasites in the human body can penetrate the eyes, heart, lungs, can parasitize the skin.

Alveolar dangerous because it can metastasize to the brain. In this case, the person is the most common symptoms, with severe pain, dizziness, etc. it is not excluded, fatal disease.

Symptoms of giardiasis (Giardia).Giardiasis is a parasitic protozoal infestation, which provokes intestinal Giardia. Asymptomatic carriage occurs in 25% of cases.

Other cases of a characteristic clinical picture:

  • Disruption of the functioning of the digestive system.
  • Complaints of pain in the navel and the right hypochondrium.
  • Characterized by nausea, belching, loss of appetite, bloating.
  • The chair is often frothy, may occur up to 5 times a day. Diarrhea alternating with constipation.
  • When the acute form of the disease has passed, infection becomes subacute period. People began to lose weight, sometimes the effort of his intestinal symptoms.
  • The heavier the infestation, the more symptoms of intoxication. The long-term rise in body temperature, CNS depression (irritability, fatigue, decreased performance, weakness, nervousness, mood swings).
  • In children, giardiasis is often manifested in the form of urticaria, the appearance of ticks, unconscious state, itching.

Symptoms of parasites in humans countless. The severity of symptoms depends on firstly, the immunity of the patient and where the parasite entered the body, and where it is a parasite.
