  • You can defeat parasites!

The parasitic world is huge - there are more than 200 species of various worms that infect the human body. They can be small, which cannot be seen without a microscope, or large by several meters. Helminths can affect one or several internal organs at once.

Infection is accompanied by negative symptoms, which are similar to signs of the development of other pathologies. However, knowing what parasites live in the human body, you can start treatment in time.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

Round worms

The group of roundworms is also called nematodes. These are parasites with a thin, elongated and pointed body shape. The rounded, spindle-shaped structure of the body influenced the name of this group of worms.

Today, science knows about the existence of more than 24 thousand different nematodes - they are considered the second most diverse type after insects.

The habitat of roundworms is diverse:

  • bodies of water - both salty and fresh;
  • different soil;
  • decomposing organic substrate.

Symptoms of nematode infection develops depending on the stage of the invasion.

Early stage Late stage
Sometimes it can be asymptomatic. It is usually noted:

  • deterioration of health;
  • body temperature rises;
  • the functioning of the organs of the digestive system, liver, spleen worsens;
  • soreness and enlargement of the lymph nodes develops.
At the stage of exacerbation, or chronic, a person may face:

  • upset stool;
  • abdominal pain;
  • bouts of nausea, vomiting;
  • loss of appetite;
  • unstable psycho-emotional state;
  • it is possible to develop a dry cough without signs of colds, which over time are accompanied by the release of sputum mixed with blood;
  • due to the destruction of the integrity of internal organs, bleeding and anemia may appear.

Treatment is selected individually. The patient is usually prescribed the following anthelmintic drugs:

  • Dekaris;
  • Piperazine;
  • Pirantel.

Therapy may be accompanied by the intake of sorbents, vitamin complexes, immunomodulators, antihistamines.

Tapeworms

The life cycle of cestodes depends on intermediate hosts. They are the largest representatives of all helminths; they can grow up to 10 m in length. Invertebrates are intermediate carriers of tapeworms.

For development into a sexually mature individual, this parasite needs to enter the intestines of the final host. As a result, larvae are formed from the eggs, and later on, adult worms.

Tape worms (cestodes)

They are distinguished by a ribbon-like body shape, divided into segments (segments). They are hermaphrodites, so infection with even one parasite leads to its reproduction. Each segment of the helminth is filled with eggs (about 200 per segment), which are hatched outside.

The invasion is accompanied by a variety of symptoms, which depend on the type of parasite and its localization:

Diphyllobothriasis, hymenolepiasis
  • Decreased appetite;
  • Nausea;
  • Stomach ache;
  • Dizziness;
  • Drowsiness, general weakness;
  • Dermis discoloration;
  • Swelling of the face, limbs.
Teniarinhoz
  • Hepatic colic;
  • Pancreatitis;
  • Gastroduodenitis;
  • Appendicular colic;
  • Epileptic seizures.
Teniosis
  • Itching in the anorectal region;
  • Feeling of a lump in the throat;
  • Stool disorders, with discharge of fragments of the worm.
Cysticerki
  • Migraine;
  • Seizures;
  • Epileptic seizures;
  • Deterioration of mental abilities;
  • Mental disorders.
Echinococcosis
  • Pain in the right hypochondrium;
  • Pain in the lower chest that radiates to the back;
  • Feeling of swelling in the abdominal cavity is possible;
  • Dry cough;
  • Bleeding;
  • Labored breathing.

Deworming of tapeworms is carried out under the supervision of a physician. Usually, Albendazole and Mebendazole are prescribed for treatment.

In some cases, surgical therapies are required. The rehabilitation period is accompanied by the intake of drugs aimed at rapid recovery of body functions.

Suckers

Flukes are representatives of a group of flatworms that require an intermediate host for development. Unlike tapeworms, it has a more simplified internal structure. They eat the foods that surround them.

They differ in special adaptations for life:

  • the presence of a cuticle;
  • there are suckers, hooks on the body;
  • regressing nervous system;
  • primitive digestive system;
  • depending on the host and the stage of development, a different mode of existence can be observed (sexual, asexual);
  • a change of host saves the parasite from overpopulation, promotes reproduction;
  • a complex life cycle improves survival.

Symptoms Treatment
  • Allergic skin rash;
  • Coughing fits, possibly with pus;
  • Enlargement of the liver, which is accompanied by pain;
  • Vomiting, pain in the lower abdomen;
  • Loss of appetite;
  • Increased body temperature (about 40 degrees);
  • Chills, fever;
  • Chest pain;
  • Shortness of breath, shortness of breath.
Fluke therapy consists of several stages:

  1. Preparing the body for treatment;
  2. Anthelmintic therapy using drugs based on albendazole;
  3. Rehabilitation treatment aimed at accelerating the process of regeneration of damaged organs, improving the protective functions of the body.

The best way to protect yourself from parasite infestation is to follow the rules of hygiene and prevention. Treatment is selected individually based on clinical manifestations, laboratory results.

It is strongly discouraged to self-medicate with any parasite infestation - this can not only aggravate the problem, but also complicate the process of further treatment with recovery.
