Types of intestinal helminths, symptoms of the disease and methods of treatment

There are about 250 types of worms that pose a threat to the health of an adult. As a result of infection with parasitic worms, the disease helminthiasis develops. The vital activity of worms in the internal organs can cause severe allergies, hypovitaminosis, pancreatitis. All age groups of the population are susceptible to infection, but a higher rate of infection in children.

Most types of worms are inside the body, only there they lay eggs and die after a certain period of time.

Forms of parasitic worms and features of their development

Depending on the method of distribution, the main groups of parasites are distinguished:

  1. biological worms. In the process of passing through the full cycle of development, several owners are replaced. These include tapeworms, nematodes, echinococci.
  2. Geohelminths. Able to spread without intermediate hosts, but through the soil. A person becomes infected by eating unwashed vegetables and fruits. The main representatives: roundworm, whipworm, necators.
  3. Helminths transmitted by contact with an infected person. This group includes pinworms and dwarf tapeworms.

More than 150 species of helminths registered in humans are known.

Parasites also differ in location in the body:

  • tissue affect the internal organs and tissues that make up their composition;
  • abdominal live in the intestinal lumen, absorbing the nutrients needed by a person.

In appearance, helminths are divided into 3 groups:

  • roundworms;
  • flatworms;
  • flukes.

Methods of infection with helminths

In most cases, parasites enter the host organism in the following ways:

  1. Worm larvae or eggs, along with feces, end up on the soil or in water, infecting a person when eating unwashed foods or raw liquids. During the summer holidays, the likelihood of invasion through water bodies increases.
  2. By contact with a sick person or shared objects. This mode of distribution is typical for pinworms. At night, the female leaves the anus and lays eggs. This process causes severe itching, as a result of which the eggs remain on the hands and underwear. Subsequently, they indulge in a healthy person.
  3. Infection with tapeworms occurs when eating raw and insufficiently processed meat. Tapeworms of this species infect the muscle tissue of intermediate hosts, which include cattle and pigs.
  4. Insects can carry eggs and worm larvae on their limbs, increasing the area of potential infestation.

The life cycle of the overwhelming majority of parasites consists in the release of a huge number (millions) of eggs, which, penetrating into the human body, after a certain time turn into larvae.

The development of the parasite in the human body can cause acute and chronic forms of the disease. The acute form is characterized by pronounced symptoms and persists for up to two months. Chronic invasion can be observed throughout a person's life if left untreated.

The main types of helminths that parasitize humans

Each form of a microorganism is characterized by a lesion of a certain organ and the corresponding symptoms. However, all parasites are united by the method of obtaining nutrients - at the expense of the host organism. At the same time, a person's metabolism is disturbed, anemia and other types of diseases develop.

There are different forms of helminths:

  1. Roundworms are large white nematodes up to 20 cm long. Adults live in the small intestine, and the larvae can move through the circulatory system to the lungs. They belong to geohelminths, infection occurs when unwashed vegetables, fruits and water are consumed. Parasite eggs also accumulate on the sand.
  2. Pinworms are small worms that can be seen with the naked eye after a bowel movement. Distribution zone - the lower part of the small intestine. Under the influence of the parasite, enterobiasis is formed. The cause of infection is contact with an unhealthy person. It is very common in children under 14 years of age.
  3. Tape helminths. These include bovine and pork tapeworms, wide tapeworm. They are distinguished by the ability to increase the population at a rapid pace, thanks to hermaphroditism. Their body is made up of many parts, containing a reproductive system and thousands of eggs. Depending on the type of parasite, different diseases are formed. Localized in the small intestine, damage the epithelium mucosa. Accumulate in the lumen of the intestine and can cause its obstruction. Infection occurs when eating undercooked beef, pork or fish.
  4. Vlasoglav - a round worm that looks like a hair with a thickened back. Due to the peculiarities of the structure, it penetrates into the blood vessels and feeds on tissue fluid. Lack of treatment leads to a decrease in the body's resistance to infections and cancer. The source of invasion is unwashed products.

The insidiousness of helminthiasis lies in the fact that it successfully disguises itself as other diseases.

The development of the parasite from an egg to a sexually mature individual occurs within three weeks. During this period, symptoms may be absent or manifest in a mild form. If left untreated, the intensive reproduction of worms will lead to the fact that the disease becomes chronic.

Signs of disease with helminth infestation

The main symptoms of infection with worms are manifested in the form of:

  • weakness and fatigue;
  • pain in the intestines;
  • constipation alternating with diarrhea;
  • swelling on the face or throughout the body;
  • inflammation of the lymph nodes, coughing and suffocation;
  • skin rashes that provoke itching;
  • pain in the joints.

The topic of parasites is unpleasant and scary, so many myths about these harmful organisms have arisen.

The consequences of infestation with worms are often disguised as other diseases. The difference between pathologies lies in the specific signs of disturbances in the functioning of the body. Depending on the type of helminth, there may be:

  • increased salivation, a slight increase in temperature, urticaria with ascariasis;
  • frequent urge to urinate, sleep disturbance, nagging pain in the navel when infected with pinworms;
  • nausea, vomiting, pallor of the skin, hypotension with tapeworms;
  • yellowing of the sclera, dizziness, heaviness in the liver, aches all over the body in case of invasion of flukes.

It is important to detect worms in a timely manner with the help of tests and apply effective treatment.

Symptoms of helminthiases directly depend on the type of parasite, its localization in the body and the intensity of infection.

Methods for sampling material for the detection of intestinal parasites

The main analysis that allows you to accurately diagnose the presence of worms is the study of feces. The material is handed over to the laboratory in a sterile container on the day of stool collection. The use of laxatives and the ingress of urine on the material is unacceptable. The stool container should be stored in the refrigerator at 4-5 degrees until sent to the laboratory.

Additionally, the following tests may be prescribed:

  • immunological test;
  • blood and urine analysis;
  • scraping from the vagina in women and girls;
  • sputum examination in the presence of cough;
  • Ultrasound and endoscopy;
  • bile analysis.
blood test for worms

ELISA blood test is an effective way to detect helminths in the body.

A person can become infected with one type of helminths, or several. As a rule, the presence of single individuals in the body is characterized by the absence of symptoms. An increase in the population of worms leads to severe damage to the internal organs, which is the cause of poor health. Symptoms of the disease are aggravated at night, which additionally affects the resistance to the parasite.

Treatment methods for helminthic invasions

Specialized drugs affect different groups of helminths. The use of drugs is possible both in case of infection and for prevention. Prescribe medications only after identifying the type of worm that hit the body.

Adult ascarids and pinworms are destroyed with drugs containing mebendazole, which blocks the worm's ability to feed and multiply.

preparations for removing worms from the body

Modern tablets from worms are divided into three groups, depending on the sensitivity of parasites to medicines.

Vlasoglav is affected by preparations containing mebendazole and albendazole. Iron-containing preparations are necessary to eliminate the consequences of rectal prolapse.

The course of treatment is prescribed strictly by the attending physician. Self-administration of medicines is unacceptable due to various contraindications.

The use of traditional medicine

The most common remedy for worms are pumpkin seeds. They are consumed in the morning on an empty stomach, after grinding and adding honey. The recommended dose is about 300 grams per hour. After taking it, it is necessary to clear the stomach with laxatives.

Various decoctions and infusions have proven their effectiveness:

  • tansy;
  • gentian yellow;
  • immortelle sandy;
  • garlic.

Folk remedies for worms in adults are recommended for preventive and therapeutic purposes.

A decoction of wormwood is recommended to be used as an enema. It is possible to use fresh grass juice mixed with alcohol. Carrots and its juice also destroy parasites.

Preventive measures against worms and their effectiveness

Clean hands are the most effective way to protect children and adults from any type of parasite infestation. The concept and rules of personal hygiene should be formed in children from an early age. A healthy lifestyle also helps to reduce the likelihood of the disease.

Purified or boiled water should be available around the clock to eliminate the possibility of drinking contaminated fluid. Vegetables and fruits are best washed with boiling water.

Care must be taken when dealing with animals. Pets must be treated for various parasites, both externally and internally. Do not forget about routine vaccinations for dogs and cats.

vaccination of animals and people against worms

Vaccinations will minimize the risk of losing a family member from one of the common diseases.

It is possible to use prophylactic drugs prescribed by a doctor. Infection with worms can progress into dangerous diseases, so it is important to minimize the risk of getting worms into the human body.
