According to the World Health Organization, about 4. 5 billion people are infected with one type of parasite or another. In this case, most often it is not clear that "settlement" has occurred. Signs of parasites are not always obvious; sometimes they are similar to the symptoms of other diseases, from which they can be differentiated using different examination methods.
Types of parasites and places of their localization in the body
Many types of parasites have now been discovered. Some of them can be found quite often in your body.
Pinworms
Quite common in young children and teenagers. They live in the large intestine. Their length is no more than 1-1. 5 cm in length. Their peculiarity is that, living in the folds of the large intestine, they lay eggs on underwear and skin folds. Egg maturation occurs within 6 hours. In this case, the child feels severe itching, grinds his teeth in his sleep, eats little, and gets tired quickly. This parasite can enter a child’s body through dirty hands, toys, toilet seats, dishes, and underwear of other children.
Toxocars
The carriers of this parasite are domestic animals - cats and dogs. In their body it reaches 30 cm. Toxocara eggs can survive for quite a long time in soil and sand. They get from there through human hands, and can also stick to clothes and shoes. After this, they enter the body, where they spread through the vessels and internal organs, but are not carried out.
Ascaris
This pathogenic organism is the most common; it is found annually in 100 million people. Spreads through food, soil, water, dirty hands. The parasite reaches 40 cm in length. The female lays up to 200 thousand eggs every day. They end up in the soil, where they can persist for many years. If the penetration of parasites occurs through food, they penetrate the intestines, spread through the bloodstream through the capillaries, into the liver, brain, lungs, eyes, constantly multiplying. Roundworms feed on red blood cells and nutrients that come from human food. As a result, a person often develops various types of anemia, disturbances in the functioning of the digestive system occur, and allergic reactions occur. When roundworms penetrate the respiratory tract into the deeper layers of the skin and lungs, diseases such as bronchial asthma, neurodermatitis, arthritis, convulsions, fever and other symptoms that are similar to bronchitis or pneumonia develop. If the lungs are affected by roundworms, the following are possible: rupture of pulmonary vessels, hemoptysis and other unpleasant symptoms reminiscent of tuberculosis.
Often the location of sites of parasite damage is the liver, biliary tract, pancreas, kidneys, causing disturbances in the normal functioning of these organs. In particularly difficult cases, the following may occur: intestinal obstruction, purulent processes.
Wide tapeworm
This type of parasite can reach 10 m in length. In the patient’s body it is in a twisted state. Its nutrition comes from the nutrients consumed by humans. As a result, a person experiences exhaustion of the body, iron deficiency anemia, nausea, morning vomiting, abdominal pain, loss of strength, and drowsiness.
Infection with this type of parasite occurs most often through raw fish.
Bovine (pork) tapeworm
Tapeworm infection occurs through meat products - raw or undercooked. The length of this parasite reaches from 2 to 7 meters. Can live in the human body for up to 20 years. The main danger of this parasite is that it can infect the brain and eyes.
Echinococcus
Infection with this type of parasite occurs from infected animals, soil-contaminated fruits or berries, through water. The larvae of parasites penetrate the body and spread throughout the bloodstream, affecting various internal organs: kidneys, liver, brain, as well as the lymphatic and skeletal systems. In addition, echinococcal larvae can degenerate into cysts, growing to such a size that they compress nearby internal organs. Symptoms depend primarily on the location of the parasites.
General symptoms of the pathological condition
There are a lot of common signs of this pathology, but each of them may or may not appear depending on the location and type of parasite.
- syndrome of intestinal, gastric discomfort;
- dysbacteriosis;
- constipation;
- diarrhea;
- bile stagnation;
- weight change;
- problematic skin;
- allergy;
- pain in joints, muscles;
- anemia;
- decreased immunity;
- avitaminosis;
- sleep disturbance, nervousness;
- chronic fatigue;
- oncology.
Stomach discomfort is one of the signs of parasites
Intestinal or stomach discomfort
Many types of parasites are located in the upper or lower intestines, which leads to inflammation of this area, disruption of its functioning, and bloating. In this case, the absorption of nutrients decreases. If the location of the parasites is in the upper intestine, then the fats are not broken down, but enter the lower sections, thereby causing spasms, alternating constipation and diarrhea.
In addition, this symptom is usually accompanied by:
- pain in the epigastric region;
- pain on the left and right side under the ribs;
- nausea, heartburn;
- decreased or complete lack of appetite;
- constipation or diarrhea;
- flatulence;
- dysbacteriosis;
- intestinal/biliary colic.
If the digestive tract is not functioning properly, other accompanying symptoms are also observed, which affect the condition of the skin:
- rashes of various types (acne, pimples);
- pigmentation;
- decreased tone, frequent formation of wrinkles;
- dehydration, dry skin;
- change in complexion - sallow, dull tone.
Stagnation of bile
Parasites located in the biliary tract or nearby organs, due to their large size, can block the ducts of the tract, which creates blockage of the common duct and difficulty in the outflow of bile, causing obstructive jaundice.
This problem also negatively affects the condition of the skin.
Weight change
The change in body weight can be either up or down. This is a consequence of a parasitic disease. Weight reduction occurs due to the consumption of nutrients by the "sub-settler". Obesity is also due to the fact that the parasite consumes everything a person eats, which is why he has a false feeling of hunger. The feeling of unsatiation also occurs due to the fact that the helminth poisons the "host’s" body with its feces and a drop in blood sugar occurs.
Changes in body weight are a possible sign of parasites
Pain in muscles and joints
Parasites look for the most convenient place for themselves and sometimes "settle" in joints or muscles. As a result, tissue injury or an immune reaction to their presence in the body occurs. This causes a person to experience muscle or joint pain.
Allergy
Parasites disrupt the functioning of the digestive system, as a result of which undigested pieces of food enter the lower intestines. The immune system reacts to this by activating the body's protective cells - eosinophils, which contribute to the development of an allergic reaction. Parasites also contribute to increased secretion of immunoglobulin E, which also contributes to an increase in the allergic reaction.
Decreased immunity
The presence of a parasite in the body impairs immunity. The synthesis of immunoglobulin A, which also maintains the level of immunity, decreases. As a result, the body becomes susceptible to the negative influence of various bacteria and viruses.
Therefore, patients are often infected with colds, viral and other diseases.
Sleep disturbance, nervousness
Toxic secretions of parasites negatively affect the functioning of the central nervous system, cause constant nervousness, worsening the quality of sleep. Patients often experience night awakenings between 2 and 3 a. m. , which are caused by the body’s "desire" to get rid of toxic substances secreted by parasites through the liver.
If the brain is damaged by parasite larvae, the following signs are possible:
- difficulty reading;
- hyperactivity;
- attention disorder.
Sleep disturbance is a possible symptom of the presence of parasites in the body
Constant lack of sleep, nervousness and anxiety negatively affect the condition of the entire body, including the skin.
Chronic fatigue syndrome
Its signs include:
- general weakness;
- decrease or increase in body temperature not due to any reason;
- emotional instability;
- depression;
- apathy towards all aspects of life;
- impaired concentration;
- poor memory;
- absent-mindedness;
- rapid fatigue with minimal physical activity.
These symptoms may also be caused by other diseases that are caused by the parasitic presence.
Diagnostic methods
Diagnosing the presence of parasites is quite difficult, especially in the first period after their "invasion". Previously, the most effective methods were stool analysis and duodenal intubation. These studies made it possible to determine the presence of fragments of parasites, their eggs and larvae. But these methods did not always give reliable results. Currently, examinations are being carried out that help determine the presence of parasites with an almost 100% guarantee.
- stool analysis (at least 3 times);
- ELISA tests;
- enzyme immunoassay;
- ultrasound examination of internal organs;
- serological examination methods;
- computed tomography;
- PCR diagnostics, which involves analysis for parasites using DNA analysis;
- endobiopsy.
If there are signs of parasites, a stool test is prescribed
These research methods not only help determine the presence of parasites, but also identify various diseases and disorders in the functioning of systems and organs, as well as assess the condition of internal organs.
If there are several signs of parasite damage, you should immediately contact a specialist who will prescribe all the necessary tests. In this way, it will be possible to detect the "settler" in time and protect yourself from its negative effects on the body.
