Passing a worm in your stool is a definitive sign that you have parasites.

Other important signs include excessive food cravings and/or weight loss, despite eating large portions of food. Indigestion, frequent gas, abdominal pain, and food poisoning all hint at the possibility of parasites. If your elimination consists of chronically soft stool or acute watery stool and diarrhea, you may be harboring unwelcome visitors. Many parasites cause anal itching. If you experience bloody stools, constipation, or IBS, consider getting tested to determine whether parasites are ravaging your GI tract.

Next, consider your tongue. Is it coated? Does it have depapillated regions - places where it looks irritated, as if a piece of it was scraped off? Is your tongue swollen with teeth marks around the edges? Do you have a bitter or metallic taste in the mouth? All of these can indicate changes in the digestive tract caused by parasites. However, these signs may be present in individuals without parasite infection as well.

• Parasites destroy ojas so may see signs of dryness or low ojas on tongue. This may include cracks as well as bare patches on the tongue (a peeled tongue).
• Parasites create inflammation so you may see rawness or heat signs on the tongue such as a yellow coating, red dots (inflamed papillae), or rawness due to toxic mucus. Your tongue may be swollen (with scalloped edges) due to inflammation and low agni.
• Parasites create ama so you may see a thick coating on the tongue.

Parasites can make you feel jittery and prevent you from sleeping soundly. Their waste products contain toxins that can make you a bit cuckoo, a condition called "verminous intoxication." These toxins can also cause joint pain, reactive arthritis, and skin irritation. They may wake you up throughout the night to pee. They can cause you to grind your teeth. Parasites can make you feel weak and fatigued. These little vampires can lead to anemia as they rob your body of nutrients.

Parasites frequently secrete specific hormones and chemicals to make your body a more hospitable host. For example, blastocystis secretes chemicals that shut down your immune system, making you more vulnerable overall to infection. If you experience frequent urinary tract infections or vaginal yeast infections but your diet is otherwise clean, think about getting tested. Also consider getting tested if you frequently get sick for no apparent reason.

Parasites often have cyclical flare ups that coincide with the moon or a particular time of year. Every parasite has a different life cycle. Some will cause pain in the upper GI, others will cause pain in the lower GI. You may find one of these invaders passed in your stool, which is why it's always a good idea to check out your poop before you flush. Traveling increases your risk for contracting a parasite because you have no natural immunity in a foreign territory.

Beware! Parasites are often stealthy and keep their presence under the radar by causing no signs or symptoms at all. That's why an antibody or DNA stool test is your best bet to ensuring you are parasite free.

Parasites flourish when the weather is warm and moist. That makes autumn an ideal time to get tested and to cleanse your body of summer parasites.

Some parasites are classified as both good and bad bacteria, depending on who you talk to. In that case, some discernment may be required before taking a pharmaceutical. Otherwise, parasites should be killed as quickly as possible, before they have a chance to adapt to your gut or cause permanent damage. Once parasites adapt, they are more difficult to get rid of.
