Worms in humans: symptoms of helminthiasis in adults

If there are worms in humans, symptoms will be determined by their appearance, localization and severity of infestation. Worms is a collective term that unites hearts, which lead a parasitic way of life. About 200 species of worms can live in the human body.

Clinical manifestations of helminthiasis

Helminthic infection occur in people of all ages. The risk group includes young children. This is due to the not fully formed hygiene skills and visits of organized groups (schools, kindergartens). Worms are parasites that live in various bodies. There are 3 large groups of parasitic worms:

  • geo-helminths;
  • bio-worms;
  • contact.

Symptoms of worms are sometimes absent. It is possible then, if the body is inhabited by single individuals. Worms in children and adults often parasitize in the intestine. Rarely affects other organs (lungs, liver, bladder, lymphatic vessels, skin, brain, bile ducts). Most often in people are the following lessons:

  • ascariasis;
  • beef tapeworm infection;
  • echinococcosis;
  • opisthorchiasis;
  • difillobotrioz;
  • strongyloidiasis;
  • gimenolepidoz;
  • trichinosis.

At worms symptoms depend on the disease phase. There are acute and chronic stages of the development of helminthiasis. Most pronounced signs of the presence of worms is detected at an early stage, when there is sensitization of the organism. The acute stage lasts from 2 weeks to several months. During this period, most often develop an allergic reaction is the immune system's response to the introduction of parasites.

The chronic phase can last for years. Some worms (cestodes) live in the human body for 10-20 years, leading to serious consequences. Signs of worms in the adult appear after contact with eggs. Rarely in the human body introducing live larvae. The contamination is also possible through food (unwashed vegetables, fruits, raw meat or fish), water or direct contact with the patients. How you get rid of worms in humans, is known to every doctor.

Clinical manifestations in the acute stage

The first symptoms do not appear immediately, but after a few days. Symptoms of helminthiasis in adults occur after a short incubation period. On average it is 2-3 weeks. Under certain parasites it lasts up to 1. 5 years. The lesson may manifest allergic reactions. They occur in the first weeks of being infected. Worms in the process of growth and development of toxic substances that cause intoxication of the organism.

Of an allergic reaction are rash, swelling, cough, pruritus. In severe cases develop asthma and bronchitis. The rash is a reaction of the body in response to the release of histamine, which is manifested by accumulation of blood plasma and a raising of the epidermis. Some helminths (Trichinella) can cause severe allergic reactions in the form of edema of the face and rash. The latter is papular, and the type of urticaria. In the presence of intestinal worms in humans symptoms and treatment be determined by your doctor.

A severe reaction may develop on the background of echinococcosis. This occurs due to rupture of the cyst. In this case, there is a risk of anaphylactic shock and death. Symptoms of infection with worms in the acute phase include not only allergies. Often patients with increased body temperature. With a massive invasion of deteriorating overall health. Often there are catarrhal symptoms. In the acute form of ascariasis often appear cough and chest pain.

Signs of helminthiasis in the chronic stage

In the presence of worms in the adult, the symptoms depend on the localization of the parasite. In the chronic stage revealed the following signs of infestation:

signs of worms
  • unstable stool;
  • bloating;
  • pain;
  • a decrease or increase in appetite;
  • pain in muscles and joints.

Intestinal worms in humans secrete substances that disrupt the process of digestion. Worms fed by his master, in this connection, in the body there is a lack of certain compounds. Parasitic worms lead to dysbacteriosis. Worm infestation is often accompanied by loose stools.

Less likely to develop constipation. This is possible if blockage of the intestines by worms. Lesson lead to decreased immunity. This is particularly clear in children. It is proved that worm infestation reduces the effectiveness of vaccination. Not all worms live in the intestines. Often affects the liver, biliary tract and the lungs.

Signs of worms in humans include neurological disorders. The higher the intensity of the infestation, the more symptoms of lesions of the nervous system. The toxins that are formed in the process of life parasites cause headache, dizziness, weakness, decreased performance. In severe cases, a migraine develops.

The symptoms of helminth infection include inattention, insomnia, absent-mindedness. Patients often become irritable. Infected children do not learn and can't concentrate. Worm infestation in the chronic form often leads to the development of asthenovegetative syndrome. Helminths can cause anemia. Often develop hypovitaminosis. They are manifested by dry skin and cracked, brittle nails and hair, bleeding.

Signs of infection pinworm

Symptoms of worms in humans is known to every doctor. The most common worms are pinworms. This worms are of elongated shape with a pointed end. They reach a length of 1 see the First signs of worms appear after a few days after infection. The acute stage lasts about a week.

What worms appear, knows not everyone. People infected by close contact with patients. Factors of transmission may be any items which contain eggs of the parasite. More common in young children and schoolchildren. In the acute phase the symptoms of the presence of worms in humans include abdominal pain, diarrhoea, discomfort, nausea, flatulence.

The presence of these signs is due to the following violations:

  • the mechanical action of the parasite on the intestinal wall;
  • the release of toxins;
  • allergic reaction;
  • violation of digestion.

The symptoms of worms in adult often absent. Prolonged infestation by parasites causes itching, increased pain and neurological complaints. Small children tire quickly, constantly crying and being left behind. In girls, these worms can cause the development of candidiasis. The disease leads to inflammation of the small intestine or colon. Itching is a specific symptom of infestation. It is the result of irritation of the worms secreted substances.

Heavy infestation can cause the development of appendicitis, dermatitis, eczema and abscess. Amid the scratching of possible septic complications. It is established that the infestation complicates the course of pregnancy and other infectious diseases. In the presence of these worms treatment combined with sanitation and hygiene activities as required to prevent re-infection.

Clinical manifestations of ascariasis

You need to know not only what the worms are, but how dangerous roundworm. These are the larger worms, which reach a length of 40 cm They live in the small intestine. People get oral way. Distinguish early (migration) and late (intestinal) stage of the disease. Phase circulation of larvae in the human body manifested by the following symptoms:

  • various rash;
  • malaise;
  • fever;
  • enlargement of the liver and spleen;
  • increased sweating;
  • weakness;
  • cough;
  • the pain in his chest.

Frequent manifestation of ascariasis is the development of bronchopulmonary syndrome. Some patients revealed eosinophilic pneumonia. When roundworms migrate through the lungs, shortness of breath and rales are heard. In this helminthiasis symptoms of sensitization of the body is gradually weaken. Developing the late (intestinal) stage. It is characterized by morning sickness, diarrhea, weight loss, periodic vomiting, bloating, sleep disturbance.

When this worm infestation symptoms include convulsions, loss of memory and attention. In severe cases in children, there is delayed psychomotor development. Sometimes there are epileptic signs. If treatment for worms in adults and children is not possible, you can develop the following complications:

  • cholangitis;
  • intestinal obstruction;
  • perforation;
  • appendicitis;
  • peritonitis;
  • acute inflammation of the pancreas;
  • damage to the liver.

Known cases when the roundworm climb into the Airways and lead to suffocation. This is possible when a large number of worms and irrational treatment.

A dangerous roundworm and pregnant women. They can cause severe toxicity and delayed development of the baby.

The symptoms of trichinosis

People who do not eat enough ready-cooked meat of infected animals, can be infected with trichinosis. This is a dangerous disease from the group of nematodes. These worms enter the human intestine together with food. The greatest danger is the meat of wild animals (boars, bears). The incubation period is 10-20 days.


Larvae of Trichinella with the flow of blood to penetrate into the muscles. To determine the presence of worms in the body by the following symptoms:

  • pain in the muscles;
  • fever;
  • edema;
  • soreness of the skin at the selected sites;
  • rash.

In the acute stage of the disease deteriorates overall health. Manifested fever of the wrong type. Body temperature reaches 40ºC. Fever often associated with chills, nausea and vomiting. The patients face becomes puffy. The cause of the edema — allergic reaction. Most often affects the eyelids. With a massive invasion of the swelling down on the trunk and limbs.

What are the signs typical of acute trichinosis, known not for everyone. Patients often develop allergic conjunctivitis. In the presence of data in the body symptoms of worms in adults and children include muscle pain. This is a specific symptom of trichinosis. The muscles affected from the bottom up.

In severe cases, can movement. A permanent sign of the presence of Trichinella is resistant eosinophilia. The acute form of infection is characterized by dyspeptic disorders, pain in the abdomen. If the treatment of worms is not possible, then develop complications. On the background of trichinosis it can damage the heart according to the type of myocarditis. Often develop meningoencephalitis, hepatitis, pneumonitis, myositis, pleurisy. Trichinella can lead to the particular syndrome.

How to get rid of worms, the patient should tell the doctor.

Cestodes - signs of infection

People can get tapeworms. The name of these worms of the cestodes. This group includes cepni (bovine, swine and rabbit). In the presence of these worms in the adult the symptoms are often nonspecific. Man becomes infected by eating poorly cooked meat of infected animals (pigs, boars).

The clinical picture of infection pork tapeworm is represented by the following syndromes:

  • asthenic-neurotic;
  • abdominal;
  • dyspeptic.

The appearance of symptoms associated with allergic reaction, damage to the intestinal mucosa by hooks and suckers of the worms and indigestion. Asthenic-neurotic syndrome include sleep disturbance, mood lability, and persistent headaches. When teniasis often concerned about pain in the lower abdomen: it is dull and aching. Dyspeptic syndrome is manifested by belching, irregular bowel movement and abdominal discomfort.

In a group of tapeworms include beef tapeworm. Infection is the consumption of cattle meat, have not passed thermal processing. These worms reach 12 m in length. In the presence of these worms in the human body the following symptoms:

  • nausea;
  • heartburn;
  • loose stools;
  • increased salivation;
  • malaise;
  • sleep disturbance;
  • pain in the iliac or epigastric areas;
  • the presence of segments of the parasite in the stool.

Patients with loss of appetite may change its increase. Very often the beef tapeworm infection is asymptomatic. Infection of bovine tapeworm leads to a decrease in gastric acidity and anemia. Complications are rare. The human body can be the habitat of such a parasite like tapeworm wide. It causes a disease called difillobotrioz. This parasite can reach 10 m or more in length. Method of transmission of the parasite is raw fish.


Specific signs of infection lentetsa wide is the development of B12-iron-deficiency anemia. Asymptomatic period is 1-2 months. This can cause obstruction of food. In the case of severe infestations lead to neurological disorders that is manifested by sensory and motor disorders. B12-deficiency anemia has symptoms such as dizziness, pale skin, swelling, inflammation of the tongue, pain while eating.
