Some parasites cause cough

Most people cough is perceived as a manifestation of any colds. But not everyone knows that a cough can cause a variety of parasites, trapped in a human body. Typically, worms do not usually Express themselves in the host body too openly. But often the parasites enter the respiratory system where they start their action. For this reason, a person has a cough of varying intensity. If you suspect the presence of the body in worms, it is recommended to find out what parasite is causing the cough.

A variety of parasites that cause cough

Known 4 main types of worms cause people to cough:

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

Most often, the parasites choose the main place of his activity in the intestine. But over time, as a result of a rapid increase in the helminth larvae begin to actively move throughout the body. Means of travel on the human body is the bloodstream. So, the parasites enter the liver. Later they moved and settled in the body.

Can parasites get into the respiratory organs? The worms enter the lungs and the bronchi via the blood vessels. The food of the parasite is the blood and tissues of the body, where they live. Of course, their lives helminths secrete a variety of products, highly toxic to the internal organs of the human body. As a result, the person experiences inflammation, decreased immunity, there are serious diseases.

Giardia and roundworm can live in any organ of the human body and their penetration into the breathing organs have more to do with it, find a new point of habitat.

Toxocara and lung Fluke consciously choose as the main activity in the trachea, lungs and bronchi of a person. This type of worms can often cause coughing in humans.

Part of the worms, which live in the respiratory system, leaving the body wet cough and nasal discharge. Still some of them return to the host organism, is on a journey to the intestines, the lungs and bronchi.

Fluke and ways of their penetration into the body

Present in the body of the lung flukes are of the following symptoms paragonimoz:

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

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

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

Giardia and the cause of their symptoms

Unlike all the other parasites Giardia to a lesser extent, manifested in the human body the early stages stay. The presence of Giardia in the human body does not occur until a certain period of time.

After the asymptomatic period, cough. Start treatment now, because the symptoms worsen, and caused by parasites giardiasis becomes chronic.

With the progression of the human disease are noted:

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

The most common complication of action Giardia human bronchial work asthma.

Get lamblia. The main sources of infection are:

  • unwashed fruits and vegetables;
  • stagnant water, its drinking and bathing;
  • the infected milk;
  • open bodies of water.

Roundworms and their effect on the respiratory system

Roundworm more often than other parasites, betray their presence in the human body in the form of cough. After swallowing the roundworm starts its activities. The larvae of Ascaris, mainly living in the trachea. Due to the presence of tracheal cilia 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 together with the mucus released from the cough, but then again they can find their way back. The second part of the larva re-enters the oral cavity to the stomach and then into the intestine, when the person swallows the saliva.

The background activity of worms in humans appears first on light dry cough. Over time it passes through the wet. In the later stages the presence of ascarids in the body, when the cough begins to stand blood.

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

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

The reason you get the larvae of ascarids in the human body are:

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

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

Toxocara and their effects on the body

Toxocara is the most dangerous to the human body. The presence in the body is manifested in various symptoms:

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

These symptoms are a sign of toxocariasis caused by this type of worms. Because Toxocara are often called the dog ascarid, the main source for them to get into the people are dogs. Particularly high risk of infection after contact with stray animals, but it is often Toxocara Pets, which is not done with proper care.


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

Complications of the respiratory system against the background of infestations

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

Cough remedies are ineffective, if it is due to the presence of respiratory parasites. At untimely or incorrect treatment of people with severe complications. Primarily affect the lungs. Because of the diseases that can cause worms, the patient has pneumonia. Worms often cause a variety of cancers, the respiratory system.

Often concomitant phenomenon of life parasites of the bronchial asthma development.

Because all body systems are interconnected, with the progression of the worms the disease begin to suffer from other organs. Affects the optic nerve, violation of visual function.

Seriously affect the skin. As a result, it looks like a rash that most often appears on toxocariasis. Disturbed metabolism. Patient develops goiter, against which there is diarrhea and vomiting.
Because of the breeding of worms the respiratory organs in humans is a violation of the ventilation. For this reason, an increase in pathogenic parasites can cause asthma attacks, deadly to humans.

The necessary diagnostics

The diagnostic can be used to detect which parasites can be in the respiratory system. 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, to gather data on the presence of worm infestation of the bronchi, lungs and trachea.

The main tests are:

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

Fecal makes sense only within the first hour of intake. The study of blood pay attention to the red blood cells and number of eosinophils. They are a kind of white blood cells, which perform the function of cleansing the blood of foreign organisms. With a significant excess of the norm is reason to suspect the presence of worms in the body.

Blood suffer from helminthiasis show a low hemoglobin. Often required to perform several tests, because the worm 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 processing depends on helminths, the operation of which caused the particular disease.

Treatment and preventive measures

Treatment of diseases caused by parasites of the respiratory tract is complex. Based on anthelmintic drugs. These funds will be assigned based on the patient's age, weight, severity of the disease.

Cough and parasites can be treated with specific drugs aimed at correcting it. These drugs are used to reduce spasms of the bronchi.

To avoid the worm infestation of the respiratory organs with the help of the following conditions:

  • monitoring of the health of domestic animals and regular deworming to prevent the ingress of eggs and larvae of parasites in the body;
  • use disinfectant gel for your hands after contact with any animals, frequent hand washing after visiting toilet, common places;
  • careful personal hygiene of small children, because they are more susceptible to helminthiasis technologies respiratory;
  • wash vegetables and fruit under running water and treated with boiling water if necessary;
  • avoid swimming in stagnant water bodies unchecked.

There are quite a number of parasites that can cause irritating cough and other unpleasant symptoms, which cause a person discomfort and suffering. To avoid this, you should observe personal hygiene, immediately seek medical help.
