Which parasites cause allergies in humans?

A negative reaction from the body can occur not only in animals, plant pollen, medicines and food. An increase in histamine in the blood can cause helminths and protozoa. Which parasites cause allergies and how to deal with this phenomenon, we will consider in more detail.

Types of parasites that cause allergies

Not all helminths and protozoa are allergens that can cause a negative reaction in the human immune system. There are several types of parasitic pathogens.

  1. Unicellular organisms or lamblia. They can cause atopic dermatitis in children, eczema, neurodermatitis. Disorders appear in the work of the intestines, worsening sleep, irritability is observed in the context of severe itching of the skin.
  2. Helminths - echinococcus, roundworm, toxocara. These parasites cause hives, edema, itching, bad breath and asthma in humans. In addition, ascaris larvae are able to form focal necrosis within the body, which leads to severe inflammation of the affected tissues.
  3. Fungi, bacteria, viruses. These organisms are called infectious allergens that cause negative reactions in the immune system.

The most dangerous parasites that cause allergic reactions are worms and lamblia. Its negative impact on the body occurs in two ways. First, helminths poison human organs and systems with the products of their vital activity. And secondly, there is an acute intoxication with decomposing substances from dead individuals.

Causes and relationship

To understand the relationship between worms and allergies, you need to know the reasons why some worms cause an increased sensitivity of the immune system in adults and children.

Roundworms and toxocaras disrupt the metabolic processes of the human body, depriving it of important trace elements, minerals and vitamins. This drains the immune system, it starts to react violently. As a result, skin rashes, shortness of breath and abnormalities in the functioning of the stomach and intestines occur.

Another reason why a parasitic allergy appears is the toxic effect of the worms' waste products. Harmful substances poison human lymph and blood.

In addition, parasites have a destructive effect on intestinal microflora. As a result of this process, pathogenic microorganisms begin to grow sharply, which leads to the body's reaction in the form of faecal disorders, inflammatory processes, flatulence.

The negative processes associated with the development of helminthic invasions cause disturbances in the functioning of the defense system, increasing its sensitivity to foreign antigens - a condition close to immunodeficiency. As a result of pathological changes, dangerous diseases arise that the person does not associate with helminth invasions, and for a long time is treated with the wrong drugs, triggering the main cause of the disease.

Symptoms and course of the disease

If we start from the relationship between worms and allergies, the symptoms of a negative reaction of the body to the parasites will be similar to the typical allergic manifestations. Normally, the skin and the digestive system, and sometimes the respiratory system, are the most affected.

The main symptoms of a worm allergy:

  • skin rashes of various locations in the form of hives, eczema, dermatitis;
  • decreased bronchial lumen, bronchospasm, development of asthma;
  • severe itching, redness of the skin, blisters and swelling;
  • severe cough, fever, fever;
  • runny nose, swelling of the eyelids, lips, yellowish skin.

Important!The facet stage of ascaris and echinococcus can cause anaphylactic shock. It all depends on the number of parasites and their prevalence in Organs internal organs.

Severe allergic reactions in children are caused by lamblia. They cause the development of eczema, atopic dermatitis. The child's skin is covered with purulent acne or rough plaques. These manifestations are clearly visible in the photo.

Symptoms in the early stages are almost invisible. They intensify with the intensive development of helminthic invasions. Gradually, immunity decreases, infected children and adults are more likely to get a cold, have constant malaise, fatigue, decreased appetite and bowel disorders.

People rarely associate these manifestations with worms and do not immediately consult a doctor. In this case, the disease worsens and the condition worsens.

Treatment methods

To get rid of allergic manifestations, you need to eliminate the source of its occurrence. Therapy should be directed mainly to the destruction of parasites, their eggs and larvae. In addition, the doctor selects medications to remove toxic decomposition products from dead helminths from the body.


The medication can be prescribed as a course or as a single dose. The method and dosage are chosen by the doctor.

The treatment must be complemented with cleansing enemas. This will help to quickly remove dead helminths, their eggs and waste from the human body, thereby reducing poisoning. The best way to perform the procedures is 12 to 14 hours after taking the medication.

Parasite prevention

Based on the fact that helminths may be associated with allergic manifestations, it is necessary to try to prevent them from entering the body.

  1. Compliance with hygiene rules. Most parasite infestation occurs precisely through dirty hands (especially in children).
  2. Careful handling of food. Meat and fish must be well fried, boiled or salted. Wash vegetables and fruits thoroughly in plenty of water.
  3. Keep pets. If there are cats or dogs in the house, it is necessary to monitor the condition (deworming, vaccination), hygiene of the tray and feeding containers.

By adhering to these rules, you can protect yourself and your family members from dangerous helminth infections.

Some types of worms are actually capable of causing allergic manifestations in the form of hives, dermatitis, eczema. In severe cases, asthma, Quincke's edema and anaphylactic shock can occur. Therefore, with a noticeable decrease in immunity (frequent colds, fatigue, loss of appetite, apathy and nervousness), it is recommended to consult a doctor immediately. The sooner the source of the allergy is identified, the better the disease will respond to treatment.
