Can you see intestinal worms in feces

Some tapeworms live in water, and drinking unclean water may allow them into the body. Other tapeworms live in meats, such as beef or pork, and ingesting unclean or raw meats may expose the person to them. Tapeworms are flat and tend to be long, usually between 3 and 10 meters depending on the type of worm. The name of the worm describes the way that one end of its body tapers off into a needle or hook shape. The CDC state that, according to estimates, to million people in the world have a hookworm infection.

Hookworms take up space in the small intestine, where they lay eggs, which pass out of the body through the feces. When the eggs hatch, the larvae can potentially enter through the skin of another person. People are at risk if they come into contact with the fecal matter or with soil containing contaminated feces as fertilizer. Most people with a hookworm have no symptoms. Some people may show typical gastrointestinal symptoms, and this may be more common with first-time infections.

Flukes are another type of flatworm. Flukes may be more common in animals, although it is possible for humans to contract these parasitic worms as well. Flukes are small and have a rounded leaf shape. Humans get them by accidentally eating or ingesting them, either in drinking water or freshwater plants, such as watercress. Some people do not have any symptoms, but others may experience symptoms months or even years after first ingesting the parasite. These people may experience inflammation of the bile ducts or complete blockages.

They may have an abnormally large liver or unusual readings on a liver test. Pinworms are relatively harmless and sometimes live in the colon and rectum of humans. Someone who has the worms can pass them onto someone else through direct contact or by sharing a contaminated object with them. Pinworms commonly cause itching around the anus, which can be severe enough to make sleeping difficult.

Symptoms appear during the night as this is when the female pinworms crawl out of the anus to lay their eggs on the surrounding skin. Ascariasis is similar to a hookworm, although it is only a few inches long. It lives in contaminated soil, so it only enters the body when people ingest the eggs.

Inside the body, this worm lives in the intestines. People with an ascariasis infection often show few to no symptoms. However, severe infections may cause intestinal blockages or impair growth in children. Trichinella worms are another type of roundworm that may pass to humans who eat undercooked or raw meats that contain the live larvae. The larvae then grow in the intestines. On reaching their full size, the Trichinella worms may leave the intestines and live in other tissues, such as the muscles.

Symptoms vary with a trichinosis infection. In addition to common gastrointestinal symptoms, some people may experience:. Heavy infections may cause breathing or heart problems or make it difficult for the person to move. Very severe cases may lead to death. Trichinella infection is rare in the U. As a study notes, over 3.

The vast majority of these infections occur in developing countries where sanitation is poor. However, intestinal worms are still possible in developed areas. When they come out in the poop, they start the life cycle all over again. Most people with ascariasis don't have any symptoms.

Those who do can have symptoms that range from mild to severe depending on how many worms are in the intestines. Symptoms also depend on which part of the body is affected. They include:. Kids are more likely than adults to complain of gastrointestinal symptoms.

That's because their intestines are smaller and more likely to get blocked by the worms. A large mass of worms in the intestines can lead to malnutrition and poor growth.

It can also block the appendix and other organs, leading to appendicitis or problems with the liver, pancreas, or gallbladder.

Ascariasis doesn't spread from one person to another. To become infected, a person has to swallow the worm's eggs. Doctors can diagnose ascariasis by looking at a worm that comes out when someone coughs or poops. They can also test stool samples for eggs. Sometimes, imaging tests like an X-ray, ultrasound, or CT scan can show the worms in the belly or chest.

Doctors treat ascariasis with prescription anti-parasite drugs. Symptoms usually stop within 1 week of starting treatment. Very rarely, doctors do surgery to remove the worms. This usually happens only if they block the intestines or cause problems with the liver, pancreas, or gallbladder.
