Helminthiasis is the most common parasitic infection that affects people of any age. Doctors cannot give exact statistics on the number of cases, since many do not go to a specialist when they detect alarming symptoms, but prefer to treat themselves. This approach can lead to serious complications becauseEven broad-spectrum medications may be ineffective against certain types of helminthic infestations., for example, filariasis: infection by filamentous nematodes.
In total, more than 400 varieties of helminths are known that can parasitize the human body, and it is possible to accurately determine which of them caused the disease only after laboratory examination of feces. It is necessary to consult a doctor (general practitioner, proctologist or infectious disease specialist) if signs of helminthic infestation are detected. The difficulty of timely diagnosis in almost half of cases lies in the absence of typical symptoms of helminthiasis, so it is important to know what signs may be indirect manifestations of helminthiasis. It is recommended that adults undergo preventive stool analysis, as well as scraping for enterobiasis, at least once a year.
How can you get infected?
Most patients believe that helminth infestation is a "disease of dirty hands. "This statement is only half true. Some varieties of worms, for example, cestodes and other flatworms, can live in soil and sand, therefore, in the absence of sufficient hand hygiene, a person can become infected with helminthiasis, but this route of transmission is typical mainly of children of the younger age group (from 1 to 6 years). In adults, the main source of infection is poor quality food (expired dairy products, poorly processed meat, rancid eggs) and tap water.
How does worm infection occur?
You can become infected with worms in open rivers and reservoirs. In rare cases, while swimming, a person can become infected with leeches - representatives of the class of annelids that cause hirudinosis. The pathology is quite serious, since the main food of leeches is blood and its components, which causes damage to blood vessels, rapidly progressing anemia and blood poisoning against the background of systemic intoxication of the body. To avoid this, you should not swim in places that are not equipped with signs indicating that swimming is allowed. In summer, soil and water samples are periodically taken in specially designated places and the risk of infection in these places is several times lower.
Other sources of infection for people may include:
- stray and domestic animals (the pet's tray should be cleaned only with gloves, and the animal should be bathed regularly and treated with anthelmintic drugs 2 times a year);
- polluted air;
- blood-sucking insects (mosquitoes, ticks);
- dust (including household dust that accumulates on stuffed animals and upholstered furniture).
Note!Some types of worms can enter the human body through the skin, so body contact with a person who has been diagnosed with helminthiasis should be limited as much as possible.
Helminths spread quickly throughout the body.
Acute infection in adults: symptoms and signs
It is possible to diagnose or suspect a helminth infestation independently at home only during the period of acute and subacute course of the disease. Depending on the type of worms, their number and the state of the immune system, it can range from 1 week to 4 months. The symptoms of pathology during this period are more pronounced, so the chances of timely treatment and reducing the risk of complications in the acute form are maximum.
The main symptoms of acute helminthiasis are disturbances in intestinal function. The patient develops functional intestinal disorders in the form of diarrhea or prolonged absence of stool (constipation is 4 times less common compared to diarrhea syndrome). The consistency of feces when infected with worms is thin, watery, sometimes with the addition of foam. The smell is foul, acrid. The color can vary, but in most patients the stool becomes lighter in color and pale yellow. If there is a heavy worm infestation, the droppings may be brown or green. Sometimes they contain streaks of mucus and blood, which are released as a result of damage caused by worms to the blood vessels and capillaries located in the intestinal mucous membranes.
Among other signs from the gastrointestinal tract, the patient may have abdominal pain, sudden and causeless vomiting, loss of appetite against a background of constant nausea. Many patients lose weight during this period: weight loss can reach up to 10% within 2 to 4 months from the onset of the disease. The skin turns pale and a polymorphic rash appears in the form of vesicles or nodules filled with exudate. The same rash can occur on the mucous membranes of the genitals, oral cavity and internal organs. Approximately 10% to 20% develop acne, boils, and comedones during this period. A spot red rash may appear on the skin of the abdomen and elbows.
Other signs of acute infection in an adult include:
- inflammation of the conjunctiva of the eye (parasitic conjunctivitis);
- swelling of the face, limbs and neck (may be accompanied by dropsy of internal organs);
- febrile condition;
- fever and chills against the background of periodic increases in temperature to 38°C and above.
Important!Anal itching, which is considered the main symptom of helminthiasis, is characteristic primarily of enterobiasis, a pinworm infection. It occurs as a result of irritation of the skin in the anorectal area with the secretion secreted by the female pinworms at night. For other acute forms of helminth infestation, this clinical picture is not considered typical.
Chronic infestation: what symptoms to pay attention to?
The chronic form of helminthiasis is a very common pathology that develops in the absence of timely treatment in the acute period. Most clinical symptoms diminish and lose intensity during this period, but do not disappear completely. A person may periodically experience mild pain in the abdominal area, nausea, and possible vomiting immediately after eating or 1 to 2 hours after eating. Skin rashes usually persist. If the reaction is severe, the patient may experienceAngioedema is a fatal disease accompanied by laryngeal spasm and bronchospasm..
One of the main signs of a chronic helminth infestation (as well as its complications) is anemia. It manifests itself as unnatural paleness, asthenia (chronic fatigue syndrome) and weakness. A person's performance decreases, he becomes lethargic, and emotional lability may be observed.
If the hepatobiliary system is affected.
The hepatobiliary system, which includes the liver, gallbladder and bile ducts, is the main target of parasite attacks. Worms can feed on liver parenchyma cells, blood, bile components, and bile acids. This form of pathology is manifested by intense pain located under the right rib in the upper part of the abdomen. The pain can be stabbing, cutting or dagger-shaped, which is why many people confuse it with an attack of biliary colic (this situation is especially typical for patients with chronic diseases of the gallbladder and ducts).
Obstructive jaundice is another sign that requires immediate diagnosis. Yellowing of the skin and sclera of the eyes can be a manifestation of dangerous liver diseases (hepatitis, cirrhosis) or symptoms of damage to organ tissue by parasites.
Important!Hepatobiliary helminthiasis is one of the most serious types of pathology. In the absence of adequate and timely therapy, the patient can die from acute poisoning and necrosis of liver tissue.
Clinical indicators: signs of helminth infestation.
A doctor may suspect parasitic infections if the results of three blood tests confirm that the patient has anemia, a low level of hemoglobin. For an adult, the hemoglobin norm is 120-140 g/l. In some cases, for example during pregnancy, this figure may be slightly lower, up to 110 g/l. But the amount of hemoglobin should not fall below these values. Anemia in patients with helminthiasis develops rapidly, since almost 90% of the parasites feed on human blood and damage small blood vessels.
Another constant clinical sign of long-term helminthiasis isEosinophilia: absolute or relative increase in the level of eosinophils in the blood.. This is a type of granulocytic leukocyte mass, which is the main indicator of the allergic readiness of the body. When infected with parasites, it is always combined with itchy skin and a polymorphic rash.
How to protect yourself from worm infection?
The basic rule that helps protect the body from the penetration of worms is strict compliance with hygiene, first of all, hand hygiene. For washing, it is better to use soap with antibacterial components or natural laundry soap with a fatty acid concentration of at least 72%. Laundry soap has a pronounced disinfecting and antimicrobial effect and provides excellent prevention of infectious diseases. If you cannot tolerate the smell of laundry soap, you can use a product to which aromatic additives have been added.
Food must be prepared in accordance with hygienic and heat treatment standards. It is recommended to rinse vegetables and fruits with boiling water or wash them with soap, and fry or boil meat at high temperature for at least 30-40 minutes. The minimum time to boil eggs is 20 minutes. It is important to control the quality and freshness of the products and carefully check the expiration dates. If the product does not have the necessary information and labeling, it is better to refuse the purchase.
If there are pets in the house, it is necessary to carry out a deworming course 2 times a year, even if the pet does not go outside, since worm eggs can get into the apartment on shoes and outdoor clothing. The safest deworming agent for dogs and cats is chicken-flavored tablets.
What to take for helminthiasis?
Treatment of helminthiasis should only be prescribed by a doctor, since all anthelmintic drugs are highly toxic and negatively affect the condition of the liver. The table lists frequently prescribed drugs with a wide spectrum of action, as well as their dosage, but they can only be used after laboratory diagnosis and consultation with a specialist.
Signs, treatment and symptoms of worms in an adult in the intestine.
There are about 250 types of worms that live in the body of an adult and arise as a result of the entry of parasitic worms into the human body and cause various diseases.
The presence of helminths in the intestines of people is disguised under the guise of other diseases.
A person can be treated for a disease for years without realizing that there are worms in their body. And only after helminth treatment will you feel much better.
Classification of helminths.
Parasites are divided into 3 groups:
- Intestinal worms;
- flatworms;
- trematodes.
Groups of helminths are also distinguished according to their biological characteristics:
- Biohelminths- tapeworms, porcine and bovine. During adult development, they change hosts, starting with insects and eventually migrating to humans.
- Geohelminths— nematodes, whipworms and many other parasites immediately penetrate the body of an adult and begin their development from the initial stage.
- Contact- pinworms, dwarf tapeworms. Entry occurs by an infected person.
Where can helminths live?
The parasites mainly infect the intestines of adults. But not everyone knows that there are types that can live in other organs:
- Tapeworms, nematodes and whipwormsThey live in the large intestine.
- thermotodes- enter the liver and gallbladder.
- pork tapewormLives in any organ of an adult.
Types of microorganisms that live in the adult body.
In the body of an adult, helminths such as roundworms, pinworms and tapeworms are predominantly found. They actively absorb nutrients from the body of an adult, after which metabolic disorders, anemia, severe weight loss and other types of diseases occur.
Helminths in humans:
- Intestinal worms:Infection occurs after eating unwashed vegetables and fruits.
- Wide tape:When eating raw fish.
- Intestinal worms:in contact with other people already infected with parasites and by using the same dishes and bedding.
Helminths develop over a certain period of time, generally lasting 15 to 60 days, after which the chronic stage of the disease occurs.
After the transition to the chronic stage, a person's immunity decreases. Inflammation begins immediately against the background of the weakening of the body.
Causes of worms
Helminths in humans cause severe intoxication of the body. If the worms appear in an adult, the symptoms depend on the type of parasite, the habitat and the number of parasites, which multiply several times, or even thousands of times, each day.
How long does it take for the first signs to start appearing?
For example, in the case of intestinal worms, two or three days are enough to notice a bad condition. Most often, infection with other types of parasites occurs in an adult; The first signs appear after 2 to 3 weeks, but the first symptoms of filariasis can be expected between 6 and 18 months.
The danger is that in some cases, worm disease occurs without visible symptoms. Symptoms may appear after the parasite reaches a huge size.
- pinworms— The main signs of the presence of these parasites in the body of an adult are itching, which intensifies at night. The frequency can last from one to two days and then not bother for several weeks. And if the infection is severe, itching may appear quite frequently.
- Trichocephalosis— a sign of infection with this type of helminth is the development of anemia. Nausea, dizziness, abdominal pain, constipation, diarrhea, and severe weight loss may occur.
- Intestinal worms- a rash appears all over the body, but it can also be in different parts of the body, nausea, pain in the abdomen, weight loss. If this parasite is not detected in time, the integrity of the intestine can be compromised. If intestinal worms enter the appendix, serious inflammation of this organ can develop.
If the number of helminths has increased several times, a high temperature may appear. But in rare cases, the parasitic infection is asymptomatic. But basically, helminth infection presents with signs that are not difficult to notice.
At the initial stage of the appearance of worms, it is necessary to begin adequate comprehensive treatment so that this disease does not become chronic.
How parasites enter the human body. Infection
There are four ways in which parasite infection occurs.
- Through land and water with egg worms. Through communication with animals and by ingesting food and products on which a fly with helminth eggs has landed. Every time you touch the dirt, you should wash your hands well. Vegetables and fruits collected from the site must be washed with water using a scraper or a special sponge. Spring water should not be drunk, as parasite eggs often live in the water. You should not swallow water when swimming in ponds, rivers or other bodies of water.
- From a person who suffers from parasites, such as pinworms. Reproduction occurs at night. A female comes out of the intestines and lays one or several eggs in the folds of the anal passage, after which itching naturally occurs, the person scratches, and helminth eggs remain on underwear, hands and surrounding objects. Without proper handwashing, infection occurs by introducing pinworm eggs into the mouth. This is the most common method of parasite infection.
- By eating raw and undercooked meat, and through raw fish.
- Through bites of mosquitoes, flies, etc.
When helminths enter the body, two stages of development can occur: acute and chronic.
The acute stage begins from the moment the helminths enter the human body and can last from two weeks to 2 months.
The second stage begins after a person does not get rid of the worms and lasts throughout life. When worms enter the body, poor absorption of nutrients occurs.
Where can helminths live?
The parasites mainly infect the intestines of adults. But not everyone knows that there are types that can live in other organs:

The first symptoms of worms in humans appear as follows:
- skin rash that causes constant itching;
- swelling, both all over the body and in some places;
- cough, choking;
- inflammation of the lymph node;
- weakness, fatigue;
- pain in the joints, lower abdomen;
- serious diseases;
- diarrhea, constipation, bloating, intestinal pain;
- damage to the central nervous system.

Testing for parasites in adults
To diagnose the presence of worms in the body of an adult, a stool sample is collected for investigation. For some types of helminths, additional tests are done:
- scrapings are collected from the anal canal to detect the presence of eggworms in an adult;
- in women, scrapings are collected from the vagina, navel area, and inguinal folds;
- perform an immunological test;
- Urine and blood tests are collected.
If there are individual individuals of helminths in the body, the symptoms go unnoticed by an adult. If there are a large number of parasites in the body, the symptoms present themselves in a rather complex way. Especially with certain types of worms, people suffer in the afternoon and at night.
To eliminate parasites from the human body, the doctor prescribes individual treatment.
Treatment of helminthic infestations.
In the modern world, there are many preventive measures and treatment methods that have their own specialization in the treatment of various types of parasites.
In our country there are around 70 types of helminths. Only after examining the evidence are precise treatments and medications prescribed, as the medications are highly toxic. In addition, appropriate treatment is prescribed for all types of parasites.
The course of treatment may be repeated as there is a risk of reinfection.
ethnoscience
Treatment can also be done using traditional methods. Time-tested methods are considered effective. These include eating pumpkin seeds and the tansy plant.
In the modern world, it is believed that it is best to eat pumpkin seeds in the morning on an empty stomach. You need to eat 300 grams of seeds in an hour. It is advisable to grind and add honey. Don't eat anything for four hours and cleanse your stomach with a laxative and an enema.
It is recommended to repeat the treatment after two weeks. It is also believed that carrots or carrot juice will help against parasites. A decoction of wormwood will help eliminate the problem; it should be used orally or as an enema.
Worm prevention. What is it for?
It is necessary to lead a healthy lifestyle, drink purified or boiled water, use personal hygiene items and your own dishes, bedding and other personal items.
All pet vaccinations must be completed on time. Before consuming, it is necessary to wash vegetables and fruits well and heat meat and fish. For prevention, take anti-parasite medications. Raw, dried or dried fish from freshwater bodies should not be eaten. To avoid helminth infection, it is enough to follow the prevention rules.
