1. Persistent digestive problems (cramps, bloating, etc.)
2. Nausea and/or vomiting - Most parasites attack your digestive system, causing all sorts of non-specific intestinal symptoms.
3. Anemia or iron deficiency - Worms can cause ulcers, causing enough blood loss.
4. Chronic fatigue
5. Excessive weakness - Your body spends so much energy trying to fend off the parasites that you’re just beat.
6. Craving processed/sugary foods
7. Loss of appetite
8. Never feeling satisfied or full after your meals
9. Unexplained weight loss
10. Blood sugar fluctuations - These five are related. Sometimes, these worms steal nutrients from your food before you can absorb them. So, your body doesn’t get the benefits of the food you eat. You don’t feel full and your body goes into crave mode.
11. Sore/stiff joints - Some types of parasitic infections cause flu-like symptoms, including stiff joints
12. Skin irritation or unexplained rash, hives, rosacea, or eczema - Rashes are often the body’s way of saying “whoa, something’s not right here!”
13. Traveled internationally having a bout of diarrhea
14. Previous food poisoning and you don’t feel like you’ve made a full recovery - Parasites are more prevalent abroad. If you’ve had diarrhea outside North America/Europe/Australia, there’s a chance it was due to a parasite. And sometimes your body doesn’t fully recover from a bout of food poisoning. Even after some time, you may still have some nasties in there.
15. Bloody stools
16. White specks in stool
17. Changes in the appearance or frequency of stools
18. Passing a worm in your stool - Inspect your stool! Sure, it's not the most pleasant activity, but what you remove from your body can help clue you into what’s going inside. Those same ulcers from #3 above can cause blood in your stool. Parasites can appear as white flecks or strands. Parasite infections in general can cause digestive changes. And finding a worm in your stool? Say no more.
19. Colitis - Ulcerative colitis (sores in your digestive tract) has been associated with parasite infections. It can affect you in two ways: (a) directly - worm eats away at the colon wall, inviting infection or (b) indirectly - parasites affect the immune system, causing an autoimmune response.
20. Excessive flatulence - Parasites can hang out in the upper intestine area. This can lead to an overactive immune response, which can cause bloating and excess gas production.
21. Anal/vaginal/perineal itching - Certain parasites take up shop in the lower intestinal tract. They lay eggs and attach to the lower colon and rectum. This can cause irritation and itching of the whole region.
22. Sudden food sensitivities/allergies - The immune reaction from parasite infection can lead to your body attacking itself. This can occur even with foods that didn’t bother you before.
23. Mood disorders along with digestive symptoms - Parasites steal nutrients necessary for proper mind function as well as bodily function. Mood disorders are commonly seen with parasitic infection.
24. Immune disorders with excessive number of bacterial, fungal or viral infections - Your body spends a lot of energy fighting off your parasite invaders. Sometimes, it doesn’t have as much left to defend itself from the usual bacterial and viral pests. This can lead to you becoming more prone to those other infections.
25. Constipation/diarrhea - Two sides of the same coin. Parasites can confuse your intestinal function, leading to over- or under-absorption of water. This leads to development of (sometimes alternating) bouts of constipation and diarrhea.
