Intestinal parasites are worms that are parasitic in the human intestine, eat the contents or suck blood from the intestinal wall.
In humans, they can cause serious, life-threatening diseases. They occur mainly in children living in tropical and subtropical rural areas of Africa, the Middle East, South Asia, Indonesia and Central and South America.
People from the Mediterranean areas of Europe and southern parts of North America they are relatively rare.
The adult size can reach from 1 millimeter to several meters. They invade the intestinal wall of man and begin to suck their blood or live there freely, using the nutrients.
The result of the activity of these parasites is inflammation of the small or large intestine, ulcers, anemia, deficiency of vitamins (mainly A, C, B12). In more severe cases there may be intestinal obstruction and then for help you must contact the surgeon.
The larvae can move to other organs (liver, spleen, bladder, muscles, lungs, brain) where they form cysts and cause allergic inflammation.
Infestation is the infection of human, animal or plant parasites (including worms).
Intestinal parasites can live in the human intestine for many years without causing any symptoms.
Common symptoms and signs can appear a few weeks or months after the invasion and manifest as pallor, weakness, frequent tiredness (from anemia due to loss of blood sucked by worms), sleep disturbances and weight loss.
Abdominal symptoms can last from several weeks to several months and include:
Eggs of intestinal parasites fall into the environment with infected feces of humans or animals. Outside the human body, eggs need several days or weeks to develop to the stage of the cysts, or immature worms (larvae) that can enter the human body through dirty hands or when you eat raw unwashed vegetables.
