Ascariasis is an infection in the small intestine caused by a parasitic roundworm “Ascaris Lumbricoides”.  Ascaris is a large roundworm that grows over 12 inches in length. It is the most common roundworm infection. People usually get this parasite through consumption of food without proper washing of hands. The parasite can also spread when you drink unsafe water. It can also transmit when vegetables grown in the soil are not properly cooked and washed.

The parasite can penetrate the intestinal tract. From there, the parasite can go to the lungs and into the air sacs and throat.


Literally, the infection has shown no symptoms. The symptoms may become noticeable when the worm starts to grow. Symptoms include:

Roundworms in the stomach

  • Vomiting, nausea
  • Diarrhea
  • Loss of appetite
  • Abdominal pain
  • Worm in the stool
  • Weight loss
  • Impaired growth among children

Roundworm in the lungs

  • Gagging or coughing
  • Fever
  • Chest discomfort
  • Blood in the mucus
  • Shortness of breath


The following are the risk factors of this infection:

  • People that live in tropical areas.
  • Poor hygiene and sanitation
  • Eating food with dirty hands.


Heavy infestation can infect other parts of the body and can lead to a more serious problem such as:

  • Duct blockage-the worm blocks the passageway to the pancreas and liver.
  • Intestinal blockage- a mass of worm blocks the intestine causing vomiting and severe pain.
  • Loss of appetite and poor nutrient absorption.


Doctors can diagnose ascariasis by examining the stool sample for parasites.

If the infection is heavy, doctors may suggest you undergo the following imaging tests:

  • X-rays
  • Ultrasound
  • CT Scan
  • MRI Test


The most important measure to prevent this kind of infection is a safe disposal of human waste. Other safety measures to prevent getting this infection include:
