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.
A parasite infection is most often diagnosed by a stool sample. Your doctor may have to test your stool more than once before you test positive for parasites. Once you know what type of parasite infection you have, you can choose how to treat it. Some parasitic infections disappear on their own, especially if your immune system is healthy and you eat a balanced diet.
This treatment is generally effective and proven to work. Some individuals choose natural remedies to cleanse their bodies of parasites instead of conventional treatments, although these remedies are unproven.
Some natural health practitioners claim that a large percentage of the U. Some even say it should be done once a year. There is no research to support this. Nevertheless, many natural health practitioners recommend cleansing human parasite infections with herbal supplements, such as:.
There are other naturally based, plant-derived medicines that claim to cleanse parasites from various body systems, including the intestines, liver, and other parts of the digestive tract. Your natural health practitioner may also recommend homeopathic treatments to eliminate specific parasites from your body. Your practitioner should choose gentle herbs for your detox. Because of this, be sure to ask your doctor or health practitioner before beginning any supplemental detox program.
Some herbal detox programs last two weeks on, two weeks off. Others can last for up to a month. Many herbs and remedies interact with medications. If you are taking any medications, talk to your doctor and pharmacist before beginning. Fiber is particularly important, as it keeps your bowel movements regular while you cleanse.
A nutrient-rich diet is also important for strengthening your immune system as the parasites are flushed out of your body. Natural practitioners claim that this, combined with a healthy dose of probiotics, will help protect your body against another infestation. Garlic , honey, pumpkin seeds , and papaya seeds are all touted as antiparasitic foods to include in your diet.
Some natural practitioners go a step further and recommend a grain-free, sugar-free diet. Others recommend limiting fruit intake in order to further reduce dietary sugars. To prevent further parasitic infections after cleansing, natural practitioners recommend that you avoid eating raw or undercooked meat and seafood.
When traveling internationally, avoid:. One study suggests that probiotic therapy may help control a parasite infection in progress, though more thorough research is needed. Clay Cressler, Anieke van Leeuwen and their colleagues have concluded that when large numbers of worms stake out intestinal territory in a host, they generally manage to hang in there for the long term.
By contrast, the model suggests that lone worms -- or small groups of them -- get overwhelmed by the immune system and quickly flushed from the GI tract. Some clear parasites really fast," said Cressler, assistant professor of biological sciences at Nebraska. The team's model can simulate host-parasite interactions by accounting for multiple variables: number of parasites, availability of food, body mass of the host, how much of that mass is accessible to parasites vs.
Crucially, it also factors in that parasitic worms can manipulate a host's ability to digest food and mount an immune response. As part of a recent study, the team simulated whipworm infections for 1, mice while varying the number of worms that infected their colons.
From those results, the researchers deduced that a large collective of whipworms can kick-start a self-perpetuating cycle that nearly guarantees the parasites' survival.
Though the specifics aren't totally clear, prior research has led the team to suspect that a critical mass of worms may unleash a barrage of molecules that confuse or suppress the immune system and allow the parasites to begin high-jacking a host's nutrients. And then they're even better at manipulating.
So you get this positive-feedback loop that allows them to establish a chronic infection. When a moderate number of worms infect a host, their length of stay becomes less certain and seems to depend more on other factors: How large are the host's fat reserves? Has its immune system already been primed to respond?
How much is it eating? On the latter question, the team found evidence that more food increases the odds of a long-term stay. Is there a chance that what you're actually doing is just feeding the parasite more? In this case, that's what happens. Yet when all other factors are equal, the model indicates that the quantity of parasitic worms alone may determine whether they persist in a host.
That's a potentially important advance, Cressler said, given that prior approaches have mostly treated parasite duration as a fixed, independent variable rather than one dependent on other factors.
