Intestinal worms that bother children and adults alike; 5 main causes

The growth of parasitic worms in the intestines causes digestive problems and malnutrition. The main ways in which worms enter the body are:

Contaminated food and water: The most common cause of intestinal worms is food and water prepared in unsanitary conditions. They enter the body by drinking water contaminated with worm eggs or by eating vegetables washed in dirty water without cooking them.

 

Poor personal hygiene: Worm eggs can be stuck between the nails and on the hands. Not washing hands properly with soap before eating and after using the toilet can cause the worms to enter the stomach directly through the mouth.

Contact with soil: Hookworms can enter the bloodstream through walking barefoot in soil contaminated with worm eggs. This risk is higher in farmers and children who play in the soil.

Undercooked meat: Tapeworms can enter the human body by eating meat from worm-infested animals (especially pork and beef) that is not properly cooked. Cooking meat at high temperatures can help kill these worms.

 

Pets: If your pets are infested with worms, they can spread to humans by touching them and eating them without washing their hands.
