What parasites can cause allergies in humans

what parasites in the body can cause allergies

Allergies are common in many people. Provoking factors can be various reasons, for example, flowering of certain plants, food, bites of mosquitoes, bees and other insects, as well as animal hair and even ordinary dust.

Parasites can also be one of the common causes of rashes, itching and irritation of the mucous membranes. Worms can cause quite serious damage to a person, leading to many complications, including the development of an allergic reaction. Next, we will find out what types of parasites cause allergies, as well as the main signs and treatments for this disease.

Types of parasites that can cause an allergic reaction

Often various parasitic life forms enter the human body, which settle there and can live fully, poisoning internal systems and organs with the products of their vital activity. But not all worms can cause allergies. This disease can only be caused by some of them:

  • lamblia and protozoa;
  • roundworms, toxocaras, echinococci, belonging to the helminth group.

Giardia infection can cause atopic dermatitis, neurodermatitis and eczema. Due to the unbearable itching, patients can even develop severe mental illness. Disorders of the digestive tract and stool disorders also occur. Due to the vital activity of parasites, poisoning by the products of their decomposition occurs, which provokes the development of a severe allergic reaction.

Symptoms of worm infestation

Determining the presence of parasites in the body is sometimes very difficult even with the help of laboratory tests. Components in human blood such as eosinophils can confirm the presence of worms. When the analysis gives positive results, specialists prescribe additional studies of the patient's stool for worm eggs.

Important!Most often, the first symptoms of the presence of intruders in the body appear at the stage when the parasites cause serious damage to a person.

The main symptoms of the disease include the following manifestations:

symptoms of the presence of parasites in the body
  • strong fluctuations in weight. In addition, it can be not only a loss of body weight, but also its significant increase;
  • frequent headaches that go away on their own or after taking medication;
  • bad breath;
  • stool disorder, constipation, which may be followed by diarrhea and vice versa
  • abdominal pain;
  • joint pain.

Mental health problems can include irritability, nervousness, lack of sleep, fatigue and chronic fatigue. Often, due to the multiplication of worms, intestinal permeability is disturbed. This is accompanied by the entry of undigested food particles into the bloodstream, which also leads to severe allergic manifestations.

How they affect immunity

Immunodeficiency develops fairly quickly in people infected with parasites. Worms have a negative effect on the work of all internal organs, affecting them with the products of their vital activity. Due to a decrease in immunity, the body is unable to fight off parasitic life forms, and worms multiply there without hindrance, for example, children who are often sick should be tested for pinworms, because a coldregular may indicate infection with them. Parents spend a lot of money and time getting rid of the common cold, not even realizing that other reasons can provoke the disease.

Important!Treatment should begin with a visit to the clinic. Only an experienced specialist will be able to diagnose and prescribe therapy aimed at getting rid of parasites.

Types of parasite-allergens

In addition to helminth infections, life forms such as bacteria, viruses and fungi can also cause allergies in humans. Separately, it is worth noting such types of worms as roundworms, trichinella and echinococci. Helminths and giardia are the most dangerous.

In medical practice, allergens associated with parasitic species are generally divided into two groups:

  1. Exogenous- they affect the body due to the action of worm waste, thereby causing a strong allergic reaction.
  2. Endogenous- poisoning of human organs and systems by the decomposition products of deceased individuals.

Course of the disease and features of symptom manifestation

The most common signs of allergy are severe itching and a rash that can spread throughout the body. The severity of symptoms can depend on the number of parasites in the body and the extent of damage to a person's internal organs. A manifestation such as hives, swelling and a severe itching sensation can be triggered by intestinal worms.

Important!Many people believe that rapid weight loss and excessive thinness in a person is a sure sign of infection with worms. However, this is not always the case. Sometimes a symptom of worms is a set of extra pounds.

how to recognize the presence of parasites in the body

Along with allergic manifestations, headaches and a feeling of chronic fatigue are observed. For no apparent reason, cough and watery eyes may develop.

Often, patients develop bronchial asthma, which causes bronchospasm.

Giardiasis infection is divided into acute and chronic forms.

Acute form

The disease develops rapidly, regardless of the sex, age and condition of the patient.

The main symptoms are as follows:

  • significant increase in temperature;
  • repeated nausea and vomiting;
  • severe pain in the abdomen, cuts and stabs;
  • digestive and stool disorders;
  • rash on the body of a red or pink tinge, with itching and pain.

With the correct diagnosis and treatment, the acute form of the disease passes in about 7 days and the patient recovers.

Chronic form

Usually takes a long time, which can range from several weeks to several months.

Symptoms of the disease are similar and manifest as follows:

  • redness and peeling of the skin;
  • abdominal cramps;
  • digestive disorders;
  • lack of appetite;
  • bitter taste in the mouth and dry mucous membranes.

The psychosomatic state of the patient is accompanied by sleep disturbances and worry. Apathy and nervousness can also occur.

Important!Giardia does not pose a threat to human life, but the complications it can cause can cause significant damage.

Methods of dealing with parasites

Parasitic therapy always begins with the diagnosis of the disease. In addition to laboratory blood and fecal tests, an ultrasound is often prescribed. This is done in order to identify the presence of parasites in the internal organs. An enlarged liver and spleen almost always indicates the presence of intruders in the body. Additionally, a sign such as a change in the color of the iris of the eyes may indicate an infection. This deviation can signal toxic damage to the body. Once the diagnosis is made, the doctor prescribes treatment.

Important!Only a doctor should select the drugs. Self-medication can cause permanent damage to human health, since drugs in this group are very toxic.


medicines for worms in humans

In modern medical practice, drugs are widely used that instantly act on parasites and are able to rid a person of helminthic invasions in a fairly short period of time.

The processing is fairly straightforward. To do this, the patient should take the dose of the drug prescribed by the doctor and after 10-12 hours do a cleansing enema or drink a laxative. Since most drugs can only kill living parasites without affecting their eggs, the treatment is repeated after 2 weeks.

The contraindications are childhood, pregnancy, breastfeeding. This is due to the fact that in addition to negative microorganisms, drugs also kill bacteria necessary for human life and digestion.

Use of folk remedies

Alternative therapies are also widely used.

Let's look at some popular recipes:

  1. Garlic and onion.These products are able to negatively affect parasites. Oral administration and enemas are used to cleanse the intestines. However, do not forget about the danger of causing a burn of the mucous membrane.
  2. Pumpkin seeds.An old method that is no less popular today. The seeds of this vegetable contain a number of components that are not tolerated by pests. For adults, the dose of the drug is 500 g of seeds, and they should be consumed with the skins. This is done a few hours before meals and the same amount after.
  3. Walnut leaves.300 g of green leaves from a tree are poured with a liter of water and put on fire. After the product boils, it is simmered on the stove for another 20 to 30 minutes. Take half a glass of the drug per day, morning and evening for 7 days.

Prevention of worms

And, of course, preventing disease by observing simple rules is also important.

These events include:

prevention of the appearance of worms in the body
  • limit contact with animals;
  • not to eat undercooked fish and meat;
  • avoid swimming in polluted waters;
  • wash your hands thoroughly before eating;
  • Provide prophylactic treatment to pets every 6 months.

Paying attention to your health and taking preventative measures will help you avoid infections and complications such as allergic reactions and other manifestations.
