General and specific signs of the presence of parasites in the human body

The signs of parasites in the human body depend on the specific type of parasite and its residues. One of the most common signs of parasites in the body is intestinal and stomach discomfort.

According to WHO statistics, about 95% of the world population is infected with parasites, microorganisms that exist and feed on other organisms. Often the signs of the presence of parasites in the human body go unnoticed because some of them are very well adapted and the signs can be confused with other diseases.

Varieties of parasites that frequently infect the human body

The human body is most often populated:

  • roundworm;
  • pinworms;
  • hookworms; lamblia;
  • whipworms;
  • optimistic tapeworm;
  • wide tape
  • ;
  • pig tapeworm;
  • echinococcus;
  • Trichinella.

Helminths are the general name of worms that exist in a living organism. Simply put, worms. They are classified according to the following types: tapeworms (cystodes), worms (trematodes) and roundworms (nematodes). The most common type of helminths are roundworms.

They are round and live mainly in the intestine, its various parts. Some of the representatives, for example, Trichinella, can migrate throughout the body. The intestine is the main place for the worms to live. Representatives of the adhesive tape pests - bovine and swine tapeworms, broad tapeworms, echinococci. The sizes of the parasites considered can reach several meters in length. Some of them begin to develop outside the human body.

Parasites in the intestines

Bovine and swine tapeworms, for example, enter the intestine at an intermediate stage. Worms can settle in several organs. They feed on blood cells, in addition, they can consume intestinal contents, mucus, etc. Its length reaches half a meter. These include liver and feline fasciole, schistosome, etc. According to the type of development, helminths are divided into biohelminths, geohelminths and contact parasites.

Biohelminths pass through the stage of maturation and development in animal organisms. These are, for example, toxocars, bovine and swine tapeworms, etc. Geohelminths develop in the soil. And they enter the person through the skin or swallowing. This includes many types of roundworms. Contact parasites penetrate a person through direct contact with another person. Enterobiasis is one of the diseases transmitted by contact parasites, the pinworms.

How the infection occurs

It is possible to become infected with larvae of the parasite by eating unprocessed food (fish, cover), raw vegetables and poorly washed fruits, insect bites, sexual intercourse, domestic use, drinking raw water and swallowing water while swimming in bodieswater, pets, through the soil.

General signs of helminths

It is often difficult to recognize the presence of pests considered on an individual's body. And many of the symptoms can be mistaken for a chronic condition and treated without success. The symptoms of the disease can vary depending on the type of worms, their location and number. But there are general signs of the presence of parasites in the human body.

Allergy

As a result of metabolic processes, worms release toxic elements that enter the bloodstream and contribute to the occurrence of allergic manifestations. The rash may appear and disappear periodically. This allergy is difficult to treat with dermatological agents.

Allergies can occur:

  • tearing, eyelid cuts and conjunctivitis
  • chronic rhinitis
  • shortness of breath, cough
  • rash, peeling and redness, burning
  • rosacea, eczema
  • seizures in the corners and inflammation of the edge of the mouth
  • leukocytosis is an increase in leukocytes in the blood
  • scabies around the anus (pinworms) and on the body
  • problematic skin and acne
  • asthma and dry cough (hookworm)
  • hair loss

Gastric and intestinal discomfort syndrome

Many parasites invade the individual's large and small intestines. They stick to the walls, irritate them and contribute to the appearance of inflammatory processes in the organs. The nutrient absorption function, especially fatty ones, is impaired.

Large amounts of fatty elements in the stool can be detected by laboratory methods.

Stagnation of bile

Due to their enormous size, some parasites can block the bile ducts and cause biliary dyskinesia. These signs can trigger other, more serious liver diseases.

Constipation

Worms can block the intestinal lumen. Often, signs of parasites in the human body are manifested by symptoms such as constipation and can even lead to intestinal obstruction.

Diarrhea

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

Dysbacteriosis

Due to intestinal dysfunction, symptoms such as diarrhea, constipation, excessive gas production, can be mistaken for dysbiosis. But in this case, treatment with antibiotics and probiotics does not give positive results.

Decreased immunity

Parasites feed on what humans eat. They absorb most of the digested nutrients.

Due to the constant response of the immune system to the presence of "strangers", the organisms' defenses are reduced and the immune system is weakened. This is manifested by frequent colds, irrational fever, body aches, etc.

Pain in the joints and muscles

Worms can affect several organs. Trichinella, for example, takes up residence in muscle tissue and can damage it. This is the body's response to the parasites' vital activity.

Change in body weight

One of the signs of helminthiasis is weight loss or obesity. Weight loss occurs due to the inability to obtain nutrients from the food consumed. And weight gain, as a result of the body's reaction, the need to "store food for future use". Therefore, before deciding to gain or lose weight, it is necessary to do a thorough examination to detect the presence of parasites in the human body.

Anemia

Some parasites, Trichomonas, for example, can infect various human organs, including blood. Feeding on its cells, helminthiasis causes anemia and iron deficiency.

Avitaminosis

A person lacks nutrients and vitamins, which causes vitamin deficiency. This is due to the gluttony of the parasites.

Nervousness, sleep disorders

Insomnia, poor short-term sleep, may be the nervous system's response to the presence of "illegal" residents. Some helminths leave the anus at night to deposit the larvae. This can cause discomfort and itching, which makes you wake up frequently and does not give you the opportunity to rest fully.

Chronic fatigue syndrome

In a context of general intoxication of the body, lack of vitamins and nutrients that are absorbed by the parasites, the individual may experience constant fatigue, decreased concentration, apathy and loss of memory.

Oncology

The presence of parasites does not have the best effect on the human body as a whole. The normal functioning of all organs is interrupted, inflammation occurs, health worsens and immunity decreases. Interruption of the normal functioning of the body due to the influence of parasites can lead to sad consequences.

It is important to know that all these signs, with prolonged action, can cause the formation of tumors and neoplasms.

Inflammation of the larynx and airways

Worms can travel throughout the body. As soon as they reach the respiratory tract, they cause a strong cough, sore throat and fever. As a result of their vital activity, even asthma or pneumonia can develop.

Do not ignore any symptoms that indicate a malfunction of the body. In the first manifestations of signs of any of the diseases, you should immediately consult a doctor, undergo parasite verification procedures. This will allow you to receive timely treatment and will not allow the destructive effect of toxins to harm your body. The presence of worms in the human body in the long term can lead to the development of serious diseases, including oncological or chronic forms of existing diseases.

Specific symptoms of parasite infestation

In addition to the 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 menstrual cycle;
  • vaginal dysbiosis, ringworm;
  • inflammation of the ovaries, kidneys, bladder;
  • uterine fibroma;
  • infertility.

For men, the disease in question manifests itself:

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

Differences in signs in children and adults

When the parasite larvae hit, they face a 3-level protective barrier:

  • saliva;
  • gastric juice;
  • local intestinal immunity.

In a child's still fragile body, this protection may not work. And children are the most susceptible to the disease in question. In summer, when babies are constantly on the streets, the risk of getting helminths is very high. For children, there are more than enough forms of infection: children's litter boxes, pets, fruits and vegetables not always washed, swimming in reservoirs. In addition, especially for the little ones, the desire to taste everything.

The habit of sucking your fingers increases the likelihood of worm infection. The most common types of parasites in children include: pinworms, mites, whipworm, toxocar. Pinworms are small white worms, at most 1 cm in size. They go out and lay their eggs close to the anus. Therefore, the presence of such parasites is always accompanied by itching around the anus. Roundworms are bigger in size, their length can reach 40 cm!

In helminth infestation in children, first of all, there are signs such as lack of appetite, pallor of the skin and weight loss. Delayed mental and physical development, memory disorder can also indicate the presence of parasites. Because of their vital activity, worms cause metabolic disturbances, decreased immunity in a child. All of this is manifested by frequent viral infections, allergic reactions.

Note that bruxism (gnashing of teeth) is considered one of the signs of parasites in the human body and tends to worry babies during sleep. Parents should pay attention to this fact and examine the child for parasites. Very often worms live in the intestines, so children can have problems with stools, flatulence, vomiting and epigastric pain.

Diagnosing parasites

Diagnosis of parasites

The main problem in diagnosing parasitic diseases is that they disguise themselves as many chronic diseases and it is very difficult to recognize the true causes of the symptoms.

How to detect the presence of parasites

When either organ or tissue is damaged, distinct characteristics predominate.

In the intestines

The most favorable place for the vital activity of the parasites: high humidity, mild temperature, ambient pH - neutral. Intestinal symptoms:

  • constipation;
  • diarrhea;
  • flatulence;
  • intestinal obstruction;
  • spastic pain, abdominal cramps;
  • weight loss;
  • vomiting;
  • nervousness;
  • lack (or increase) of appetite.

A person is overwhelmed by impotence, fatigue, unwillingness to move.

In the stomach

In case of parasitic infestation, the following signs are observed:

  • nausea;
  • burp;
  • drooling;
  • weight and distention of the stomach;
  • diarrhea;
  • bleeding during bowel movements;
  • itching in the anal area due to worms;
  • coughing due to irritation of the neuroreceptors in the stomach.

In intestinal acne, sputum can be separated with blood fractions.

In the liver

Symptoms:

  • pain in the right hypochondrium;
  • burp;
  • nausea;
  • allergic urticaria;
  • yellowing of the sclera, mucous membranes of the mouth and skin;
  • loss of hair follicles;
  • weakness;
  • irritability;
  • anemia.

Severe swelling of the legs and abdomen is observed.

With heart injury

There are always signs of pulmonary and heart failure.

  • cough;
  • shortness of breath;
  • nervousness, fear;
  • weakness;
  • chest pain;
  • arrhythmia, bradycardia;
  • temperature, fever alternating with chills;
  • drop in blood pressure;
  • sweat;
  • pallor of the face, neck;
  • anemia.

There are signs of hypoxia: cyanosis of the skin on the fingertips, triangle of nasolabial membranes and mucous membranes of the mouth.

In the lungs

Typical symptoms:

  • shortness of breath;
  • shortness of breath;
  • attacks of dry night cough;
  • asthmatic bronchospasm
  • ;
  • allergic rhinitis, sneezing;
  • chest pain;
  • rapid heart rate;
  • nausea.

The separation of foamy and sparse sputum with blood cells is possible.

Under the skin

External symptoms:

  • small itchy skin rash, large, swollen blisters on the skin;
  • ulceration
  • , abscesses, warts, eczema;
  • fever
  • ;
  • night sweats;
  • dense areas similar to mobile tumors under the skin;
  • anemia.

Cough allergic and runny nose often.

In the eyes

Different symptoms:

  • inflammation of the conjunctiva, accompanied by burning and itching;
  • eye pain and pain when looking at the side, upwards;
  • flying flies, muddy strings before the eyes;
  • eyes with dry mucous membranes;
  • blurred vision of objects, division;
  • headaches, dizziness;
  • swelling of the eyelids;
  • blue under the eyes.

Significant deterioration in visual acuity is observed.

In the blood

Blood parasites can live in both red blood cells and plasma and white blood cells. Types of pests:

  • Mansonella is a worm that can grow up to 8 centimeters. It causes dizziness, headaches and joints, fever, skin problems, numbness in the legs.
  • Hemosporidia are single-celled erythrocytes.
  • Trypanosomes are single-celled, causing Chagas disease and sleeping sickness.
  • Plasmodium malaria.

Parasitosis is disguised in thousands of diseases, so it is impossible to determine it visually, without laboratory tests. The healing period depends on the accuracy of diagnosis and detection of parasites in the early stage of infection.

Symptoms of diseases caused by parasites

Often, the disease is called the parasite that causes it.

Abdominal cramps with ascariasis

Ascariasis

The causative agent of the disease is the ascaris worm, located in the human intestine. The degree of the disease depends on the age of the patient, the severity and the duration of the parasitic invasion.

Ascariasis symptoms appear as follows:

  • an allergic skin rash located on the patient's feet, hands and body;
  • increased temperature readings, fever;
  • weakness and general malaise;
  • sweat at night and during the day;
  • enlarged liver and painful pain in the hypochondrium;
  • lack of appetite and nausea;
  • abdominal pain and cramps;
  • constipation and diarrhea;
  • weight loss or gain;
  • cough, shortness of breath and chest pain occur during the migration of ascaris and its location in the lungs;
  • insomnia;
  • decreased cognitive skills;
  • seizures;
  • obstructive jaundice and intestinal obstruction.

Teniarinhoz

Bovine tapeworm is the causative agent of the disease. Teniarinquiasis is manifested by the following symptoms:

  • nausea, heartburn and vomiting;
  • increased salivation;
  • intestinal discomfort, manifested by flatulence, constipation, diarrhea;
  • intestinal obstruction;
  • biliary tract block;
  • weakness and general malaise;
  • anemia and vitamin deficiency;
  • dizziness and headaches;
  • insomnia;
  • irritability and nervousness;
  • dysfunctions of the cardiovascular system, manifested by tachycardia and hypotension.

Enterobiasis

The disease is caused by worms, also called worms. This is the most common parasitic disease that occurs in almost everyone. Enterobiasis symptoms:

  • itching in the anus, most often at night, which is caused by the migration of female moths to lay eggs in the rectum;
  • localized redness of the skin around the anus, until the formation of eczema;
  • bruxism, sleep disorders, fatigue, nervousness and irritability;
  • urinary incontinence in children;
  • cramps and abdominal pain;
  • worsens and poor appetite;
  • constipation and diarrhea;
  • increased gas production and intestinal discomfort;
  • nausea and vomiting;
  • allergy manifested as atopic dermatitis, allergic conjunctivitis, asthma;
  • dizziness and headaches;
  • decreased cognitive skills;
  • memory and attention deficiency;
  • increased nervousness and irritability.

Toxocariasis

The causative agent of the disease is the parasitic worm toxocara, which affects human organs and tissue. The disease is widespread, as it persists for a long time with unclear and indistinct symptoms. The obvious clinical symptoms appear in the later stages of the infection.

Signs of toxocariasis:

  • the main symptom of this disease is allergic skin rashes that spread throughout the body;
  • Quincke's edema develops as a result of swelling of the skin on the upper part of the face and neck, which can lead to suffocation and death of the patient;
  • bronchial asthma manifests itself in the form of paroxysmal persistent dry cough with sputum elements. increase in temperature indicators;
  • loss of appetite, headaches;
  • enlarged lymph nodes.

With toxocariasis, worms are able to migrate and locate in internal organs, eyes, brain and epidermal tissues.

Ankylostomiasis

The causative agents of the disease are helminths, hookworms and non-pathogens. Symptoms of the disease:

  • hives and dermatitis, when the larvae penetrate the skin, edema forms at the site of penetration, which causes a burning sensation and itching;
  • bronchitis, tracheitis, laryngitis are observed during the migration of parasites by the human body, in this case the patient presents with cough, shortness of breath, hoarseness;
  • when the larvae reach the intestines, anemia, vomiting, nausea, abdominal pain, constipation, diarrhea, loss of appetite develop;
  • irritability, fatigue, insomnia.

Diphyllobotriasis

The disease is caused by tapeworm. Symptoms of the disease:

  • weight loss;
  • diarrhea and constipation;
  • loss of appetite;
  • subfebrile temperature;
  • increased tiredness and fatigue;
  • the presence of worms in the faeces in the form of white ribbons;
  • cramps and abdominal pain;
  • anemia;
  • dizziness and headaches;
  • cracks and red spots on the tongue;
  • pathological processes in the mouth and esophagus;
  • intestinal obstruction;
  • depression
  • .

Teniosis

The causative agent of the disease is the pork tapeworm, located in the small intestine. Symptoms of the disease:

  • nausea and vomiting, fragments of parasite larvae can be observed in vomiting;
  • diarrhea and constipation;
  • weight loss and appetite;
  • cramps and abdominal pain;
  • anal itching;
  • dizziness and headaches;
  • insomnia and anxiety;
  • when the larvae are located in the brain, cysticercosis develops, which is manifested by speech difficulties, epilepsy, delirium, hallucinations, loss of consciousness;
  • When the parasite migrates, it can enter the eyes, heart and lungs.

Echinococcosis

The causative agent of the disease is echinococcus tapeworm. The worm is dangerous because it is capable of forming a cyst in almost all internal organs: heart, liver, brain, lungs, etc. The disease is very insidious, since at first it is totally asymptomatic, and the clinical manifestations are already observed in the final stages of the formation of an echinococcal cyst.

Symptoms of the disease:

  • the occurrence of pain at the site of the cyst formation;
  • weakness, increased fatigue, drowsiness;
  • skin allergies, such as hives and itching;
  • disturbances in the functioning of the affected organ: if the liver is affected, appetite worsens, nausea and vomiting appear, if the lungs are affected, there is cough, shortness of breath, fever, if the brain, then epilepsy, paresis of thearms and legs, during formation, cysts in the heart can develop severe cardiopathologies;
  • When a cyst ruptures, the parasites spread at tremendous speed to all internal organs and systems, which can lead to very serious complications and even death.

Alveococcosis

The causative agent of the disease is the tapeworm alveococcus. This disease is considered slow: from the moment of infection until the development of the disease, it can take 10 years or more. Symptoms of the disease:

  • dermatological manifestations: itching and hives;
  • bitterness in the mouth, nausea;
  • pain and heaviness in the right hypochondrium;
  • hepatic colic;
  • there is hardening in the liver;
  • weight loss;
  • weakness and malaise;
  • when the parasite is located in the brain, severe headaches and dizziness are observed.

Giardiasis

The disease develops as a result of infection of the human body by intestinal lamblia. Sometimes, asymptomatic transport occurs, with no obvious signs of the disease. Symptoms:

  • disorders in the functioning of the gastrointestinal tract: nausea, vomiting, belching, diarrhea and constipation;
  • specific pain in the navel region;
  • loss of appetite, flatulence;
  • temperature increase;
  • general fatigue, reduced performance;
  • irritability and nervousness;
  • itching.
Abdominal pain with amebiasis

Amebiasis

This disease is caused by a histological amoeba. Sometimes the symptoms of the disease may be completely absent, and sometimes, on the contrary, they manifest very clearly. Symptoms are manifested in two ways: intestinal and extraintestinal. In the extra-intestinal form of amoebiasis, the lungs, brain, genitourinary system and skin are affected, but the intestinal form is the most common.

Symptoms of intestinal amebiasis:

  • excruciating diarrhea, with frequent urgency (up to 20 times), sometimes with blood;
  • abdominal pain;
  • increase in temperature indicators;
  • vomiting and nausea;
  • loss of appetite.

After a while, the symptoms of the disease may disappear on their own, for a while, and then reappear with renewed vigor.

Schistosomiasis

The causative agent of the disease is the blood schistosome. The disease has several stages of development:

  • early, the patient develops allergic reactions, which are manifested by skin rashes and edema, cough with hemoptysis, paroxysmal in nature, with general malaise and pain in the joints and muscles;
  • when the disease becomes chronic, the symptoms are limited to violation of the urination (pain and cramps when urinating, increased urination, daytime and nighttime urinary incontinence);
  • there are especially serious cases that can lead to the patient's death.

The symptoms of parasites in the human body are enormous. Without laboratory tests, based only on the symptoms themselves, it is impossible to diagnose the presence of parasites in the body. The severity of symptoms depends mainly on a person's defense mechanisms, the location of the parasite and its type.

Methods to diagnose parasites

Direct methods:stool analysis, urinalysis, scraping of the perianal region, subungual phalanges, sputum analysis and duodenal content.

Ultrasound is also used to study the presence of parasites in the body.

Indirect methods: X-ray, morphological, ultrasound, biopsy.

Bioresonance methods: Voll's method, ART.
