Roundworms usually live and grow in the host’s intestines but there are some cases that they are able to invade other parts of the body like the lungs, heart, liver and even the blood and lymphatic system.

HOW ROUNDWORMS INFECT HUMAN
Roundworm infests human through ingestion of food, items, or products that are contaminated by eggs and larva of this worms. An infected person serves as a host and can infect other people. The worms usually grow and multiply inside the intestines. The eggs and larvae are passed out the body through feces and becomes the source of contamination. Soil serves as reservoir and harbors these eggs and larvae. Poor hygiene and improper sanitation can cause the transmission of roundworms. Improper handling of food and cooking techniques can also cause of contamination. People who are fond of eating uncooked and under-cooked meats also have a greater risk of getting the the roundworm.

Children are more prone to this parasitic infestation.

As the worm grow in size and number, they can even cause obstruction to the colon contributing to the abdominal discomfort and feeling of fullness.
• DIARRHEA: Diarrhea is also common in nematode infection. Since these worms are not usually seen inside the human body; diarrhea is a common defense mechanism the body initiate to try to remove the parasite inside. Loose and frequent bowel movement can also be a response to irritation of the bowel caused by the infection triggering increase peristaltic movements of the intestine.
• MELENA: Melena or commonly known as blood in the stool can also be expected. Round worm can also cause abrasions in the lining of the intestinal wall. These lesions can bleed and mix with the stool causing streaks of blood during defecation.
• FATIGUE and WEIGHT LOSS: Loosing weight, difficulty gaining pounds or lack of energy and even restlessness are symptoms to watched out for during roundworm infestation.
