You can't tell if it's a parasite or bacteria just by symptoms, as they overlap (diarrhea, cramps, fatigue), but a doctor diagnoses it using specific tests like stool exams (looking for eggs/parasites), blood tests (antibodies/antigens), or imaging (X-rays, MRI for organ involvement), while bacterial infections are often found in blood/urine/stool cultures. Parasites are organisms living off a host, bacteria are single cells; testing identifies the specific microbe to guide treatment, as some antibiotics can help with certain parasites too.
Parasitic infections often cause intestinal illness, with symptoms like diarrhea and vomiting. But they can also give you itchy skin rashes or infect other parts of your body, like your brain or lungs.
Unexplained digestive problems, itchiness, anemia, muscular and joint pain, and inability to feel satisfied after even a hearty meal are some of the commonly experienced signs you may have a parasite. Call your doctor if your unusual signs indicate the presence of a parasite.
You know you might have parasites through digestive issues (diarrhea, bloating, pain), fatigue, unexplained weight loss, skin problems (rashes, itchiness), sleep disturbances (insomnia, teeth grinding), increased appetite, muscle aches, or even seeing worms or eggs in your stool; however, many infections have few or no symptoms, so a doctor's diagnosis via stool sample, blood tests, or other imaging is needed for confirmation.
Joint pain — there's a known link between parasite infections and arthritis, which causes joint pain and swelling.
Some of the most common signs of a parasitic infection include:
A fecal (stool) exam, also called an ova and parasite test (O&P) This test is used to find parasites that cause diarrhea, loose or watery stools, cramping, flatulence (gas) and other abdominal illness. CDC recommends that three or more stool samples, collected on separate days, be examined.
Some parasites are visually comparable to undigested foods that can appear in the stool, namely germinated bean sprouts; physicians should not only be mindful of such similarities, but should also take a full dietary history and consider any such correlations before requesting microbiologic analysis.
Common parasite symptoms may include:
To avoid health risks, it's important to check yourself over for parasites regularly. You can do this by: Looking for the signs. Common symptoms of a parasitic infection include diarrhea, bloating, gas, fatigue, weight loss, and itching around the anus.
Bacterial illness will still happen and antibiotics are the only available treatment. Discovering another treatment would be groundbreaking, which is why many researchers are exploring bacteriophages. Sometimes known simply as phages, these are a type of virus that infects and kills bacteria.
Bacteria and viruses can live outside of the human body (for instance, on a countertop) sometimes for many hours or days. Parasites, however, require a living host in order to survive. Bacteria and parasites can usually be destroyed with antibiotics.
Bacteria and parasites can often be killed with antibiotics. But these medicines can't kill viruses. Children sick from a virus can be given medicines to make them feel better. But antibiotics don't fight viral infections.
If you continue to experience symptoms like stomach cramps and pain, nausea or vomiting, dehydration, weight loss, and digestive problems, including unexplained constipation, diarrhea, or persistent gas even after trying several treatments, you may have a parasite.
Frequent (3+ per day) watery stools are a common symptom of many parasitic infections. Roundworms and hookworms can disrupt normal intestinal function, leading to diarrhea.
10 Warning Signs of Parasitic Infections
Chagas disease is often called a silent killer because many people don't realize they have it until complications from the infection kill them.
What Foods May Support the Body's Defense Against Parasites?
Among parasitic diseases, infections with the two fish-borne liver flukes of the family Opisthorchiidae (trematodes), specifically Opisthorchis viverrini and Clonorchis sinensis, can induce cholangiocarcinoma, and infection with the blood fluke Schistosoma haematobium may cause cancer of the urinary bladder (Bouvard et ...
Here are five potentially deadly parasites you should keep on your radar.
This paper discusses five parasitic diseases: American trypanosomiasis (Chagas disease), dracunculiasis, lymphatic filariasis, onchocerciasis and schistosomiasis.
There are many at-home tests for parasites. Testing for parasites at home is very easy. Our Ultimate and Advanced Gut Health Tests both test for parasites.
Ivermectin has proven to be an effective treatment for various parasitic diseases, including intestinal parasites, ectoparasites, filariasis, and onchocerciasis.
