Introduction:

Ascaris is one of the large helminths that live in the human intestine and causes the disease ascariasis. This parasite mainly enters the human body when hygiene rules are not followed.

Main part:

Ascaris lumbricoides belongs to the group of roundworms and can reach a length of 20–40 cm. It mainly lives in the small intestine and feeds on nutrients.

The life cycle of the parasite is complex: eggs are released into the external environment through feces and re-enter the human body through contaminated water or food. The larvae migrate from the intestine through the bloodstream to the lungs, then are swallowed again and return to the intestine where they mature.

Ascaris causes several harmful effects in the body:

digestive disorders

allergic reactions

intestinal obstruction (in severe cases)

general weakness and weight loss

Conclusion:

Ascariasis is one of the most widespread parasitic diseases. To prevent it, it is important to follow personal hygiene rules, thoroughly wash fruits and vegetables, and consume clean drinking water
