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

There are about 250 species of worms that pose a threat to the health of adults.As a result of infection with parasitic worms, the disease 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 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 spread, the main groups of parasites are distinguished:

1. Biological helminths.In the process of passing through the full development cycle, several hosts are replaced.These include tapeworms, nematodes, and echinococci.
2. Geohelminths.Capable of spreading without intermediate hosts, but through the soil.A person becomes infected by eating unwashed vegetables and fruits.Main representatives: roundworms, whipworms, necators.
3. Helminths transmitted by 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 up them;
• Cavities live in the intestinal lumen, absorbing nutrients needed by humans.

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. The larvae or eggs of worms, along with feces, end up on the soil or in water, infecting a person by consuming unwashed foods or raw liquids.During the summer holidays, the likelihood of invasion through water bodies increases.
2. Upon contact with a sick person or common objects.This method of spread is typical for pinworms.At night, the female leaves the anus and lays eggs.This process causes severe itching, as a result of which eggs remain on the hands and underwear.Subsequently, they are given to a healthy person.
3. Infection with tapeworms 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 eggs and larvae of worms on their limbs, increasing the area of possible infection.

The life cycle of the vast majority of parasites consists of releasing a huge number (millions) of eggs, which, penetrating 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 infestation can occur throughout a person's life if left untreated.

The main types of helminths parasitizing humans

Each form of microorganism is characterized by damage to a specific organ 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 disrupted, 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 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 defecation.The area of distribution is the lower part of the small intestine.Enterobiasis is formed under the influence of the parasite.The cause of infection is contact with an unhealthy person.It is very common in children under 14 years of age.
3. Tapeworms.These include bovine and pork tapeworms, and wide tapeworm.They are distinguished by their ability to increase the population at a rapid rate due to hermaphroditism.Their body consists of many parts containing 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. The whipworm is a round worm that looks like a hair with a thickened back part.Due to its structural features, it penetrates 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 infection is unwashed food.

The insidiousness of helminthiasis is that it successfully disguises itself as other diseases.

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

Signs of disease due to helminth infestation

The main symptoms of worm infection appear as:

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

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

The consequences of worm infestation 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, slight increase in temperature, urticaria due to ascariasis;
• frequent urge to urinate, sleep disturbances, nagging pain in the navel area when infected with pinworms;
• nausea, vomiting, pale skin, hypotension when affected by tapeworms;
• yellowing of the sclera, dizziness, heaviness in the liver area, aches throughout the body in case of fluke infestation.

It is important to detect worms promptly using tests and apply effective treatment.

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

Methods for collecting material to identify intestinal parasites

The main test to accurately diagnose the presence of worms is stool examination.The material is submitted 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 sending to the laboratory, the container with stool should be stored in the refrigerator at a temperature of 4–5 degrees.

Additionally, the following tests may be prescribed:

• immunological test;
• 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.

An enzyme-linked immunosorbent test is an effective way to detect helminths in the body.

A person can become infected with one type of helminth 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 internal organs, which is the cause of poor health.Signs of the disease worsen at night, which additionally affects resistance to the parasite.

Methods for treating helminthic infestations

Specialized drugs affect different groups of helminths.The use of drugs is possible both 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 drugs containing mebendazole, which blocks the worm’s ability to feed and reproduce.

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

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

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

Application of traditional medicine

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

Various decoctions and infusions have proven their effectiveness:

• tansy;
• yellow gentian;
• 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 to be used as an enema.It is possible to use fresh herb 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 an early age.A healthy lifestyle also helps reduce the likelihood of developing the disease.

Purified or boiled water should be available around the clock to prevent 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.Don't forget about routine vaccinations for dogs and cats.

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

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