When they do, symptoms include the following: Abdominal pain Diarrhea Nausea or vomiting Gas or bloating Dysentery loose stools containing blood and mucus Rash or itching around the rectum or vulva Stomach pain or tenderness Feeling tired Weight loss Passing a worm in your stool. What Causes It? These things raise your risk for getting intestinal parasites: Living in or visiting an area known to have parasites International travel Poor sanitation for both food and water Poor hygiene Age.
Children and the elderly are more likely to get infected. What to Expect at Your Doctor's Office Your doctor will ask if you have traveled out of the country recently and whether you have recently lost weight. If your doctor thinks you have an intestinal parasite, you will probably have one or more of the following tests: Fecal testing examination of your stool can identify both helminths and protozoa. Stool samples must be collected before you take any anti-diarrhea drugs or antibiotics, or before x-rays with barium are taken.
Several stool samples may be needed to find the parasite. The "Scotch tape" test identifies pinworms by touching tape to the anus several times, then looking at the tape under a microscope for eggs.
Your doctor may use x-rays with barium to diagnose more serious problems caused by parasites, although this test is usually not required. Treatment Options Drug Therapies Your doctor will choose the drug that is most effective against your intestinal parasite. Complementary and Alternative Therapies Conventional medical treatments can get rid parasites more quickly and with fewer side effects than most alternative treatments.
Nutrition and Supplements Avoid simple carbohydrates, such as those found in refined foods, fruits, juices, dairy products, and all sugars, except honey. Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
Blood tests can show the presence of parasites such as those that cause Chagas disease and samples of stool from bowel movements can show the presence of parasites that infect the intestines. Giardia infections: The infection usually clears up on its own within a few weeks.
If the infection is severe or does not clear up, your doctor may prescribe a medication like metronidazole Flagyl , tinidazole Tindamax or nitazoxanide Alinia. Chagas disease : Antiparasitic medications benznidazole and nifurtimox will kill the parasites, but other treatments to manage the complications like heart irregularities may be needed.
Tapeworm : The most commonly used medications to kill tapeworms are praziquantel Biltricide , albendazole Albenza , and nitazoxanide Alinia. However, if the infection has progressed and become more invasive, you may need treatment with anti-inflammatory medications, anti-seizure medications, a shunt to drain fluid from your brain, or surgery to remove cysts caused by the tapeworm.
Roundworm : There are several types of roundworm so treatment varies according to the infection. The most commonly used medications for roundworm include medendazole Vermox , albdendazole Albenza and ivermectin Stromectol.
Surgery could be required to remove the worm if there is a bowel obstruction. Most parasitic infections enter the body through your mouth, either in food or drink, or by contamination — touching your face with contaminated hands.

Parasitic Infections Parasites are organisms that live in or on another organism, called the host. Examples of parasitic infections Some people think of parasitic infections, like malaria , as occurring only in developing countries or in tropical areas, but parasitic infections exist in North America as well.
Others include: E. Echinococcosis, another tapeworm, passed through dogs and sheep Cysticercosis, or tapeworm. Toxocariasis, or roundworm. Because it can be difficult to detect Giardia , you may be asked to submit several stool specimens collected over several days to see if you are infected.
Many prescription drugs are available to treat giardiasis. Although Giardia can infect all people, infants and pregnant women may be more likely to experience dehydration from the diarrhea caused by giardiasis.
To prevent dehydration, infants and pregnant women should drink a lot of fluids while sick. Dehydration can be life-threatening for infants, so it is especially important that parents talk to their healthcare providers about treatment options for their infants. Your child may not need treatment if they have no symptoms, though it is important to consider that their poop may remain a source of infection for other household members for an uncertain period of time. However, if your child does not have diarrhea but does have other symptoms, such as nausea or upset stomach, tiredness, weight loss, or a lack of hunger, you and your healthcare provider may need to consider treatment.
The same is true if many family members are sick or if a family member is pregnant and unable to take the most effective medications to treat Giardia.
Contact your healthcare provider for specific treatment recommendations. Giardia -contaminated poop can enter ground water through different ways, including sewage overflows, sewage systems that are not working properly, and polluted storm water.
Wells may be more likely to be contaminated by poop after flooding, particularly if the wells are shallow, have been dug or bored, or have been covered by floodwater for long periods of time. Overused, leaky, or poorly maintained septic systems could contaminate nearby wells with germs from poop, including Giardia.
