Common Symptoms of Ascariasis: Identifying and Treating the Infection

Ascariasis is a common intestinal infection caused by the roundworm Ascaris lumbricoides. This parasitic worm can infect humans through ingestion of contaminated food, water, or soil that contains the eggs of the roundworm. Once inside the human body, the roundworm can cause a range of symptoms that can be distressing and uncomfortable for those affected.

One of the most common symptoms of ascariasis is abdominal pain. The roundworms can cause inflammation in the intestines, leading to cramping and discomfort in the abdominal area. This pain may be intermittent or persistent, and it can range in severity. If left untreated, the infection can potentially lead to more serious complications.

In addition to abdominal pain, individuals with ascariasis may also experience nausea and vomiting. This is often a result of the roundworms irritating the lining of the intestines, causing a disruption in the normal digestive process. The nausea and vomiting may be accompanied by a loss of appetite and a general feeling of malaise.

Other common symptoms of ascariasis include weight loss, fatigue, and visible worms in stool or even coughed up. As the roundworms consume nutrients from the host’s body, the individual may experience unintentional weight loss and a decrease in energy levels. The presence of worms in the stool or coughed up can be a clear indication of an ascariasis infection.

If you suspect that you or someone you know may have ascariasis, it is important to seek medical attention. A healthcare professional can perform diagnostic tests to confirm the infection and prescribe appropriate treatment. In most cases, medication is prescribed to kill the roundworms and alleviate the symptoms. Additionally, practicing good hygiene, such as washing hands regularly and properly cooking food, can help prevent ascariasis and other parasitic infections.

Symptoms of Ascariasis

Ascariasis is an intestinal infection caused by the roundworm Ascaris lumbricoides. The infection is most common in areas with poor sanitation and is typically transmitted through contaminated food or water.

Abdominal Pain

One of the main symptoms of ascariasis is abdominal pain. The roundworms can cause blockages in the intestines, leading to discomfort and cramping in the abdominal area. The pain may range from mild to severe.

Vomiting

Another common symptom of ascariasis is vomiting. The presence of roundworms in the intestines can irritate the stomach, leading to nausea and vomiting. In severe cases, the vomiting may be accompanied by the expulsion of worms.

In addition to abdominal pain and vomiting, other symptoms of ascariasis may include:

Weight loss
Diarrhea
Fever
Worms in the stool
Fatigue
Coughing

If you notice any of these symptoms, especially if you have recently traveled to an area with poor sanitation, it is important to seek medical attention. A healthcare professional can perform tests to confirm the presence of ascariasis and prescribe appropriate treatment.

How Ascariasis Spreads

Ascariasis is a common infection caused by the roundworm Ascaris lumbricoides. It spreads through the ingestion of contaminated food or water that contains the eggs of the parasite. Once inside the human body, the eggs hatch in the intestines and the larvae grow into adult worms.

The eggs of the roundworm are usually found in soil contaminated with human feces. They can survive in the environment for long periods of time, making it easy for them to contaminate food and water sources. When a person ingests the contaminated food or water, the eggs hatch in the intestines and the larvae make their way to the lungs through the bloodstream.

In the lungs, the larvae mature further and then travel up the windpipe. They are then swallowed back into the intestines, where they grow into adult worms. Once fully grown, the female worms release up to 200,000 eggs per day, which are then passed in the feces, continuing the cycle of infection.

In addition to contaminated food and water, ascariasis can also be spread through poor sanitation and hygiene practices. Infected individuals who do not wash their hands properly after using the toilet can unknowingly contaminate surfaces and objects, allowing the eggs to be ingested by others.

Common symptoms of ascariasis include abdominal pain, nausea, vomiting, and intestinal obstruction. In some cases, the infection can also lead to malnutrition, as the worms compete with the host for nutrients.
