Types of intestinal helminths, disease symptoms and treatment methods

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

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

Forms of parasitic worms and their developmental characteristics

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

1. Biological helminths.In the process of going through the full development cycle, some hosts are replaced.These include tapeworms, nematodes, and echinococci.
2. Geohelminths.Able to spread without an intermediate host, but through soil.A person becomes infected by eating unwashed vegetables and fruits.Main representatives: roundworms, whipworms, necators.
3. Helminths are spread through contact with an infected person.This group includes pinworms and dwarf tapeworms.

There are more than 150 species of helminths registered in humans.

Parasites also differ in location in the body:

• tissue affects internal organs and the tissues that make them up;
• Cavities live in the lumen of the intestine, absorbing the nutrients that humans need.

Based on their appearance, helminths are divided into 3 groups:

• roundworms;
• flatworms;
• flukes.

Methods of infection with helminths

In most cases, parasites enter the host's body in the following ways:

1. Worm larvae or eggs, together with feces, end up on the ground or in water, infecting a person by eating unwashed food or raw liquid.During the summer holidays, the possibility of invasion through water bodies increases.
2. When in contact with sick people or common objects.This method of propagation 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.After that, they are given to healthy people.
3. Tapeworm infection occurs when eating raw and undercooked meat.Tapeworms of this species infect the muscle tissue of intermediate hosts, which include cattle and pigs.
4. Insects can carry worm eggs and larvae on their limbs, increasing the area of possible infection.

The life cycle of most parasites consists of releasing a large number (millions) of eggs, which, penetrating the human body, after a certain time turn into larvae.

The development of parasites in the human body can cause acute and chronic forms of this disease.The acute form is characterized by clear symptoms that persist for up to two months.Chronic attacks can last a person's life if left untreated.

The main types of helminths parasitizing humans

Each form of microorganism is characterized by damage to certain organs and corresponding symptoms.However, all parasites have in common the way they obtain nutrients - at the expense of the host.In this case, 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 larvae can travel through the circulatory system to the lungs.They are classified as geohelminths;infection occurs through consumption of unwashed vegetables, fruits and water.Parasite eggs also accumulate on the sand.
2. Pinworms are small worms that can be seen with the naked eye after defecating.The area of distribution is the lower part of the small intestine.Enterobiasis is formed under the influence of parasites.The cause of infection is contact with unhealthy people.It is very common in children under the age of 14.
3. tapeworm.These include cattle and pig tapeworms, and broad tapeworms.They are distinguished by their ability to increase the population at a rapid rate due to hermaphroditism.Their body consists of many parts that contain the reproductive system and thousands of eggs.Depending on the type of parasite, different diseases develop.Localized in the small intestine, they damage the epithelial mucosa.They accumulate in the intestinal lumen and can cause obstruction.Infection occurs when eating undercooked beef, pork or fish.
4. Whipworms are round worms that look like hair with a thickened back.Due to its structural features, it penetrates blood vessels and consumes tissue fluid.Lack of treatment leads to a decrease in the body's resistance to infection and cancer.The source of infection is unwashed food.

The peculiarity of helminthiasis is that it successfully disguises itself as another disease.

The development of the parasite from an egg to a mature individual occurs within three weeks.During this period, symptoms may be absent or mild.If left untreated, the intensive breeding of worms will cause the disease to become chronic.

Signs of disease due to helminth attack

The main symptoms of worm infection appear as:

• weakness and fatigue;
• pain in the intestines;
• constipation alternating with diarrhea;
• swelling of the face or the whole body;
• inflammation of the lymph nodes, cough and suffocation;
• skin rash that causes itching;
• joint pain

The topic of parasites is unpleasant and scary, which is why many myths have arisen about these pests.

As a result of worm infestation often masquerades as other diseases.The difference between the pathologies lies in the signs of certain disorders in the body's functions.Depending on the type of helminth there may be:

• increased salivation, slight increase in temperature, urticaria due to ascariasis;
• frequent urge to urinate, sleep disturbances, disturbing pain in the navel area when infected with pinworms;
• nausea, vomiting, pale skin, hypotension when affected by tapeworms;
• yellow sclera, dizziness, heaviness in the liver area, pain in the whole body in case of fluke attack.

It is important to detect worms immediately using tests and use effective treatment.

The symptoms of helminthiasis directly depend on the type of parasite, its location in the body and the intensity of the infection.

Methods for collecting material to identify intestinal parasites

The main test to accurately diagnose the presence of worms is a stool examination.The material is sent to the laboratory in a sterile container on the day of stool collection.The use of laxatives and contact with urine on the material is unacceptable.Before being sent to the laboratory, the container with feces should be kept in a refrigerator at a temperature of 4-5 degrees.

In addition, the following tests may be prescribed:

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

Enzyme-linked immunosorbent assay is an effective way to detect helminths in the body.

A person can be infected with one or several types of helminths.As a rule, the presence of a single individual in the body is characterized by the absence of symptoms.An increase in the population of worms leads to severe damage to internal organs, which is the cause of poor health.Symptoms of the disease worsen at night, which also affects resistance to parasites.

Methods for treating helminthic infestations

Specific drugs affect different groups of helminths.The use of drugs is possible in case of infection and for prevention.Medicines are prescribed only after identifying the type of worm that has infected the body.

Adult roundworms and pinworms are destroyed using a drug containing mebendazole, which inhibits the worms' ability to feed and reproduce.

Modern tablets for worms are divided into three groups, depending on the parasite's sensitivity to the drugs.

Whipworms are treated with drugs containing mebendazole and albendazole.Iron supplements are needed to eliminate the consequences of rectal prolapse.

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

Traditional medicine applications

The most common anti-worm remedy is pumpkin seeds.They are eaten in the morning on an empty stomach, after crushing and adding honey.The recommended dose is about 300 grams per hour.After taking it, you need to clean your stomach with a laxative.

Various decoctions and infusions have proven their effectiveness:

• tansy;
• yellow fiber;
• sandy immortelle;
• garlic

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

A decoction of wormwood is recommended for use as an enema.You can use fresh herbal juice mixed with alcohol.Carrots and their juice also kill parasites.

Preventive measures against worms and their effectiveness

Clean hands are the most effective way to protect children and adults from infection by any type of parasite.The concept and rules of personal hygiene should be developed in children from childhood.A healthy lifestyle also helps reduce the chances of getting this disease.

Purified or boiled water should be available at all times to avoid the possibility of drinking contaminated liquid.It is best to wash vegetables and fruits with boiling water.

Caution must be exercised when contacting animals.Pets must be treated for various parasites, both externally and internally.Do not forget about routine vaccinations for dogs and cats.

Vaccination will minimize the risk of losing a family member to one of the common diseases.

It is possible to use preventive medicine prescribed by a doctor.Infection with worms can develop into a dangerous disease, so it is important to minimize the risk of worms entering the human body.
