If you have a parasite in your stomach it may not cause any symptoms at all, although when the parasite in your stomach and intestines does cause symptoms it mainly affects your digestive system, although they can also cause systemic issues like nutritional deficiencies as well as fatigue.
The system and physical symptoms of a parasite in your stomach and intestines include unexplained weight loss or loss of appetite, constant fatigue or weakness, anal or perianal itching, especially at night, which is caused by pinworms and nutritional deficiencies like an iron deficiency anemia from hookworms.
Common gastrointestinal symptoms of parasites in your stomach and intestines include nausea and vomiting, bloating and excessive gas, abdominal pain and cramping and persistent diarrhea, which is sometimes watery, foul smelling or even bloody.
To check if you have worms yourself, look for the physical signs of the worms in your poop and do an at home "tape test" for pinworms and also monitor for common symptoms of worms.
After pooping, check your poop closely and look for any small, white, thread like worms which are pinworms and look for flat, white rectangular segments, which look like grains of rice, which are tapeworms.
Pinworms will also often emerge to lay their eggs around your anus at night and you should do a tape test for pinworms first thing in the morning before you wash or use the toilet.
To do the tape taste for pinworms, press the sticky side of a piece of clear Scotch tape or cellophane tape to he skin around your anus.
And then remove the tape and inspect the tape as eggs of the worms will stick to the tape, which you can then also take to a doctor to look at under a microscope.
The common symptoms of worms in humans are intense itching around your anus, especially at night, unexplained weight loss or even a loss of appetite, stomach pain, nausea or diarrhea, poor sleep quality or teeth grinding and visible red or irritated skin around your anal area from scratching.
You will sometimes poop out worms after deworming although you may or may not see the worms in your poop, depending on the type of deworming medication and the specific parasite you have.
Most modern human deworming medications (like Mebendazole or Albendazole) work by paralyzing the worms or disrupting their ability to absorb nutrients.
What this does is it, causes the worms to detach from your intestinal wall.
The worms are then digested by your body or dissolved into your stool, meaning you will often see absolutely nothing abnormal in the toilet.
Visible Dead Worms: For certain infections, or if you have a high number of parasites, you might notice whole, dead worms or fragments of them in your poop a few days after treatment.
Visible Moving Worms: In rare cases, a worm might be expelled while still faintly moving as it is paralyzed and dying.
While alarming, this simply means the medication is successfully purging them from your system.
Common types of worms that infect humans are pinworms or threadworms, tapeworms, roundworms, hookworms and whipworms.
Hookworms and whipworms are generally too small to ever see in your poop or anywhere with your naked eye.
Roundworms are larger, earthworm like parasites and if they don't dissolve completely, they will look like pale strings.
Tapeworms are often eliminated in broken up, flat white segments that also resemble grains of white rice.
And pinworms or threadworms look like tiny, white pieces of thread around 1 to 13 millimeters long and they are the most common worm infection and are usually visible in poop or around your anal area.
To know if your worms are gone from your body, you should have no visible worms, segments or eggs in your poop and you should no longer have stomach aches, diarrhea or anal itching as the anal itching once the worms are gone from the body should have stopped completely for over 2 weeks.
When worms are gone from the body, you should also have clear skin and the red, itchy worm shaped rashes should have faded and a follow up stool sample provider by your doctor should come back negative.
The best way to know for sure if your worms are gone from your body are to have a stool test done by your doctor to be 100 percent sure the worms are gone.
If you think or know you have worms or a parasitic infection, you should see a doctor as they can do tests like a stool test to identify the exact type of parasite and prescribe a highly effective and targeted dewormer medication like Albendazole, Mebendazole or Pyrantel pamoate.
Pyrantel pamoate is commonly used for pinworms.
The best dewormer for humans will depend on the type of worm infection you have like tapeworms, roundworms, pinworms etc.
Some worms are resistant to some types of deworming medication and you may need a prescription dewormer in some cases to get rid of certain worms.
If you have a type of worm that over the counter dewormer won't treat, then a doctor must identify the specific parasite through tests and prescribe the correct dewormer medication to treat it.
Although the most effective and best dewormers for humans include Mebendazole (Vermox, Emverm), Albendazole (Albenza) and Pyrantel Pamoate (Reese's Pinworm, Pin-Rid).
Mebendazole (Vermox, Emverm) is highly effective against common soil-transmitted worms (pinworms, whipworms, roundworms, and hookworms).
It is also generally taken as a chewable tablet.
Albendazole also known as Albenza is a broad spectrum dewormer that is used to treat a wide variety of different parasitic worm infections, which includes tapeworms.
And Pyrantel Pamoate (Reese's Pinworm, Pin-Rid) is an over-the-counter (OTC) dewormer medication used to treat pinworms, which works by paralyzing the worms so they pass in your poop.
To get rid of worms without going to the doctor you can use over the counter deworming tablets.
Oral dewormer tablets are available directly from your local pharmacy without the need for a prescription and can work on most worms.
Medications that contain pyrantel pamoate (such as Reese’s Pinworm Medicine) are widely available at pharmacies without a prescription and work for most common intestinal worms like pinworms.
To treat the worms at home with the over the counter deworming medication you take a single dose and then 2 weeks later you take another dose to prevent reinfection from any lingering worm eggs in the body.
Although pinworms spread easily, so everyone that lives in your home with you must also be treated with the deworming medication at the same time, even if they show no signs or symptoms of having worms.
The deworming medication that you take to kill the worms, only kills the adult worms and not the microscopic eggs, which can still survive easily on surfaces for up to 2 weeks time.
So to prevent a reinfection of the worms, you should aggressively clean the area.
Wash everything, including all bed lines, blankets, towels, sleepwear and underwear in hot water and dry them using high heat.
And take a morning shower daily, instead of a bath and wash your anal area thoroughly to remove any eggs that were laid overnight.
Be sure to also disinfect kitchen and bathroom surfaces and vacuum or wet mop the floors and keep your fingernails cut very short to prevent eggs from becoming trapped underneath them.
Although if you have any intense itching, nausea, abdominal pain that persist or if a different type of worm infection is suspected and the at home deworming medication is not working, you should see a doctor.
Some worms may require a prescription deworming medication to get rid of as some worms can be resistant to the over the counter deworming medication.
