Some parasites cause coughing

Most people cough is perceived as a manifestation of any colds. But not everyone knows that a cough can provoke all sorts of parasites that were in the human body. Typically, the worms tend not to Express themselves in the host body too openly. But often the parasites enter the respiratory system, where they begin their activity. For this reason, a person has a cough of varying intensity. If you suspect the presence in the body of the worms is recommended to find out what parasite is causing the cough.

Types of parasites that cause cough

Known 4 main types of worms that provoke the person cough:

  • lung Fluke;
  • Giardia;
  • roundworm;
  • Toxocara.

Most often the parasites are mainly chosen place in your life the intestines. But over time, as a result of rapid reproduction of the helminth larvae begin to actively migrate throughout the body. Means of movement on the human body is the bleeding. So the parasites enter the liver. Later on they migrated and settled in the organs.

Or parasites can get into the respiratory system? The worms enter the lungs and bronchi through the vessels with blood. Food for the parasite is the blood and tissue of organs in which they live. In the course of their life helminths secrete a variety of products, highly poisonous internal organs of the human body. As a result, the person experiences inflammatory processes, decreased immunity, there are serious diseases.

Giardia and roundworm can live in any organ of the human body and their penetration into the respiratory system has more to do with finding a new point of residence.

Toxocara and lung Fluke deliberately choose as your main place of activity of the trachea, lungs and bronchi of a person. These types of worms often can cause coughing in humans.

Part of worms that live in the respiratory organs, leave the body with a wet cough, and nasal discharge. In the further part of them returns to the host organism, passing the way from the intestines to the lungs and bronchi.

Fluke and ways of their penetration into the body

In the presence in the body of the lung flukes are the following symptoms paragonimoz:

  • at the initial stage of penetration of parasites in the lungs and bronchial tubes the cough is wet;
  • at long stay of helminths in the body in coughing there is blood and pus.
the lung Fluke

Fluke are of the type flukes. After penetration into the respiratory system they begin to actively destroy tissue. For this reason, a person experiences inflammation. Over time, Fluke provoke sclerosis and atrophic changes in the tissue. The inflammatory process is ongoing, and the patient's condition deteriorates.

Lung Fluke most likely inside of in the process of swimming in pools of open type. The main host of the parasite is the fish and other inhabitants of reservoirs. The animals are infected with helminths through water in which they live. By eating insufficiently cooked fish Fluke is able to get into the human body, to start their livelihoods.

Giardia and the resulting symptoms

In contrast to all other types of parasites Giardia to a lesser extent manifest themselves in the human body in the early stages stay. The presence of Giardia in the human body does not manifest itself until a certain time.

After the asymptomatic period is a cough. To start treatment from now on, because the symptoms are getting worse, and is caused by parasites giardiasis becomes chronic.

With the progression of human disease are noted:

  • inflammatory processes in the lung tissue;
  • allergic reactions;
  • the intoxication of the whole organism.

Common complication of activity of Giardia in human bronchi acts bronchial asthma.

To get lamblias. The main sources of infection are:

  • unwashed fruits and vegetables;
  • stagnant water, its use and bathing in it;
  • infected milk;
  • open bodies of water.

Roundworms and their effect on the respiratory system

Roundworm more often than other types of parasites, betray their presence in the human body in the form of cough. After the ingestion of the roundworm starts its activity. The larvae of Ascaris, mainly inhabited in the trachea. Due to the presence in the trachea cilia the larvae can move from one part of the trachea in the other.


When you cough the larvae of Ascaris, can get into the mouth. Some of them come out of the body along with phlegm, which is released when you cough, but then again they can find the way back. The other part of larvae re-enters from the oral cavity into the stomach and then into the intestine after a person swallows saliva.

On the background activities of worms in humans appears at first, light dry cough. Over time, it goes in wet. In the later stages the presence of ascarids in the body when coughing begins to stand blood.

In addition to the cough, a person manifest additional symptoms, caused by a parasite ascariasis:

  • inflammation in various parts of the lungs;
  • difficulty breathing, culminating in respiratory failure;
  • the blue lips.

The reasons for getting larvae of ascarids in the human body are:

  • poorly processed vegetables and fruit;
  • failure to comply with hygiene after contact with animals.

Roundworm in the process of a long stay in the human body are able to grow up to 15 cm.

Toxocara and their effects on the body

Toxocara is the most dangerous for the human body. The presence in the body manifests a variety of symptoms:

  • paroxysmal cough;
  • blurred vision;
  • some stridor, often accompanied by shortness of breath;
  • allergic rashes on the body;
  • the increased body temperature.

These symptoms are a sign of toxocariasis caused by this type of worms. Because Toxocara is often called a dog ascarides, the main source of them getting into humans are dogs. A particularly high risk of infection after contact with stray animals, but often there are Toxocara in Pets that have not been processed in the appropriate manner.


The worms can grow up to 20 cm inside the human body. As the most suitable places for their life worms out the lungs and trachea with the bronchi.

Complications with the respiratory system against the background of parasitic infestations

When the first symptoms in the form of cough it is necessary to conduct diagnosis to determine the presence of infectious diseases in the body, but also parasitic infestations. When you confirm the last important to quickly begin treatment.

Cough remedies are ineffective, if it is caused by the presence of respiratory parasites. At untimely or incorrect treatment of people with serious complications arise. Primarily affects the lungs. Because of the diseases that can cause worms, the patient is pneumonia. Worms often cause a variety of cancers of the respiratory system.

Frequent concomitant phenomenon of life of the parasites in the bronchi development of asthma.

Since all body systems are interrelated, with the progression of helminthic disease begin to suffer other organs. Affected the optic nerve, is a violation of visual function.

Severely affected skin. As a result, it appears a rash that most often appears in the toxocariasis. Disturbed metabolism. The patient develops goiter on the background of which is diarrhea with vomiting.
Because of the breeding of worms in the respiratory organs in humans is a violation of air exchange. For this reason, multiplicati parasites can cause asthma attacks, deadly to humans.

Necessary diagnostics

Diagnostics allows to detect which parasites can be in the respiratory system. At the first symptoms of cough should be tested for the presence of infection in the body. If the data do not confirm the infectious nature of the symptom, the collection of data for the presence of worm infestation in the bronchi, lungs and trachea.

The main types of tests are:

  • the study of blood;
  • urine;
  • examination of feces for the presence of helminths.

Fecal makes sense only in the first hours after intake. The examination of blood draws attention to the erythrocyte and the number of eosinophils. They are a type of white blood cells, which perform the function of cleaning the blood of foreign organisms. With a significant excess of the norms raises the suspicion of the presence of worms in the body.

Blood tests that suffer from helminth infections show a low level of hemoglobin. Often requires conducting multiple analyses, as in the worms has its own cycle of development and reproduction.

a blood test

Parasites that cause cough, difficult to identify standard methods of diagnosis. For this reason, you need to re-research. Further treatment depends on the type of helminths, the activities of which were caused by a particular disease.

Treatment and preventive measures

Therapy for diseases provoked by parasites in the respiratory tract is complex. Based on antihelminthic drugs. These funds are assigned based on the patient's age, weight, severity of the disease.

Cough with parasites can be treated with special medicines designed to eliminate it. These drugs are used to reduce spasms in the bronchi.

To avoid worm infestation in the respiratory system will allow the following:

  • monitoring of the health of domestic animals and periodic deworming to prevent the ingress of eggs and larvae of parasites in the body;
  • the use of disinfectant gel for hands after each contact with any animals, frequent hand washing after visiting toilets, common places;
  • careful personal hygiene in young children because they are more likely helminthiasises respiratory system;
  • wash vegetables and fruits in running water and treated with boiling water when necessary;
  • avoid swimming in stagnant water bodies unchecked.

There are quite a number of parasites that can cause an annoying cough and other unpleasant symptoms that cause a person discomfort and suffering. To avoid this, one should observe personal hygiene, promptly seek medical assistance.
