- Poor sanitation practices
Diagnosis and Treatment Options
Healthcare providers typically diagnose worm infections through:
- Stool sample analysis
- Tape tests (particularly for pinworms)
- Blood tests to check for antibodies
- Physical examination and symptom evaluation
Treatment usually involves prescribed antiparasitic medications such as:

Frequently Asked Questions
What are the common symptoms that indicate I might have worms in my intestines?
Common symptoms include unexplained weight loss, abdominal pain, changes in bowel movements, fatigue, and anal itching. You might also notice visible worms in your stool or experience nausea and decreased appetite.
How do people typically get infected with intestinal worms and how can I prevent it?
People typically get infected through contaminated food or water, poor hygiene, walking barefoot on contaminated soil, or consuming undercooked meat. Prevention includes regular handwashing, proper food handling, wearing shoes outdoors, and maintaining good personal hygiene.
What treatments are available for worm infections in humans and how effective are they?
Antiparasitic medications like albendazole, mebendazole, and praziquantel are highly effective treatments. These medications typically clear the infection within a few days to weeks, depending on the type of worm and severity of infection.
Can worm infections cause complications like anemia or digestive blockages?
Yes, untreated worm infections can lead to serious complications including anemia, intestinal blockages, nutritional deficiencies, and chronic digestive problems. Some worms can also cause tissue damage and impact growth in children.
Why do pinworms cause intense itching around the anus, especially at night?
Pinworms cause anal itching because female worms emerge from the anus at night to lay eggs on the surrounding skin. This movement and the presence of eggs causes irritation and intense itching, particularly during nighttime hours.
