Ascaridosis - symptoms

It is widely believed that various parasites live only in the human digestive system, especially in the intestine. But some helminthic ways affect almost all organs in the body, including the nasopharynx, the brain, bronchus, lungs, liver and even the heart. Such invasions include ascariasis - the symptoms of the disease confirm the extensive migration of parasitic larvae and in many cases allow an unmistakable diagnosis of this pathology.

Early symptoms of ascariasis in adults

The very first clinical manifestations of helminth infection occur not earlier than two weeks after the ascaris eggs get into the body, and most often after two or three months.

The fact is that for the development of characteristic signs of invasion, the maturation of individuals of parasites is necessary, which proceeds in stages:

  1. Eggs helminths in favorable conditions (temperature about 24 degrees, the soil is saturated with oxygen) are ready for life in the human body. As a rule, this happens in the spring and autumn.
  2. The hands of a person in contact with soil contaminated with ascarids, or unwashed fruits, vegetables, berries, are seeded with eggs. If the elementary rules of hygiene are not observed, they enter the intestine.
  3. On the mucous membranes, eggs of parasites develop, passing into the stage of larvae.
  4. Maturing helminths penetrate into the portal vein and spread throughout the body along with blood, settling on any internal organs.
  5. After the migrating larvae enter the lungs, they cough into the oral cavity and return to the intestine (thin) again with saliva, where they grow to mature ascarids.
  6. Adult female parasites lay eggs (up to 250,000 pieces per day).
  7. After 10-14 months helminths die, as well as their offspring, unable to develop without contact with soil and air.

Early signs of ascariasis in humans begin to be observed only at the stage of migration of larvae:

Depending on the general state of health, the listed symptoms can be expressed or more intensely, resembling an organism's intoxication, or to appear weakly, practically absent.

Signs of the late phase of ascariasis in adults

The stage of invasion considered corresponds to the return of mature larvae to the small intestine, where they grow to adult individuals and postpone the offspring. Because of the large number of eggs in the lumen of the organ, characteristic late symptoms of ascariasis in humans appear:

With the deterioration of the immune system and severe ascariasis, complications can develop:
