Some remain in the gut, others leave and invade neighboring organs.

Some parasites are so small that they can only be seen under a microscope, while others can be long centimeters. 
Most of tapeworms and roundworms lumbricoides (nematode family) grow in the human body and lay their eggs in the gut.

 

Types of human intestinal parasites

Protozoa : Protozoa are unicellular parasites that multiply inside the human body. 
They are microscopic in nature. 
Transmitted orally (food or contaminated water) or through feces. 
The protozoa that infest humans are:

  • Giardia,
  • Amebas,
  • Toxoplasma,
  • Cryptosporidium,
  • Sarcocisto,
  • Blastocisto, etc.

Helminths : Helminths are parasites composed of many cells and are large enough to be seen with the naked eye when they become adults. 
When parasitic worms enter the adult stage, they can not multiply in the human body, but release their eggs in the intestine that are excreted in the host’s faeces. 
The common helminth worms are:

  • Tênias,
  • Oxiúros ,
  • Ancilostomídeos,
  • Ascaris lumbricoides, etc.

 

Risk factors for intestinal parasite infection

These factors increase the risk of infection by intestinal parasites:

1. International travel; 
2. Lack of hygiene (for food and water); 
3. Age – children and the elderly are much more likely to be infected; 
4. A weakened immune system, for example, because of HIV or AIDS .

 


Symptoms of intestinal parasites in humans

Constipation
Parasites can irritate the intestines and can cause:

This can cause pain during bowel movements.

Diarrhea
This symptom is common. 
The parasite assumes the nutrients that the body needs to produce the normal stool and therefore causes diarrhea .

Insomnia and nervousness
In severe cases, intestinal parasites can affect the central nervous system and prevent the person from resting. 
A parasite produces toxins in the body that can:

  • Causing restlessness,
  • Perturbar or are.

When we go to sleep, the parasite causes insomnia.

Urticaria and skin rashes
Among the most visible symptoms of intestinal parasites are skin rashes . 
Symptoms can become severe, for example, if ulcers and wounds can form . 
These are caused by the reaction of the immune system to the parasites. 
Certain types of parasites cause an intense  anal itching , similar to urticaria , especially ascaris lumbricoides. 

Bruxism
The sudden onset of bruxism is another symptom of intestinal parasites. 
Anxiety at night caused by symptoms that occur during sleep causes stress and muscle tension, the consequence is that the infected person clenches their teeth.

Abdominal distension and bloating
The intestinal gas  and bloated stomach can be caused by many things, but they are also symptoms of an intestinal parasite. 
They can cause tummy ache . 
The parasites irritate the abdominal wall or attack it.

Nausea and vomiting
The onset of nausea and vomiting may be a sign of intestinal parasites. 
The body reacts to certain types of intestinal parasites by trying to expel them from the stomach.

Increased appetite
Increased appetite may be a symptom caused by an intestinal parasite. 
The parasite eats the nutrients in the intestine (up to 5% of food ingested), spreading the toxins and forcing it to work much more than normal. 
This requires a substantial increase in appetite because your body needs more food to meet your needs.

 

Other symptoms of parasitic infestation

1. Allergies to different types of food 
2. Anemia (low red blood cell count) 
3. Blood in stool
4. Flu symptoms, such as cough , swollen lymph nodes ,  dyspnea  and chills 
5. Fever
6. Dizziness
7. Cramps abdominal
8. Slimming 
9. Deficiency of vitamin B12 
10. Anal itching
11. Colitis 
12. Jaundice
13. Weakness
14. Headache

 

How are intestinal parasites transmitted?

Intestinal parasites are spread when the fecal material enters the mouth. This can be through:

  • Contaminated water or food;
    • Raw or undercooked pork and beef,
    • Vegetables not washed (rarely);
  • Games for sexual relations;
  • Contact with feces, such as changing a diaper.

 

Diagnosis of intestinal parasites

The doctor will perform tests to find out if the patient is suffering from intestinal parasites, even if there are no symptoms. 
Tests include: 
1. Stool analysis in the laboratory to detect parasites, eggs or larvae. 
2. If the worms are not visible on examination of stool, a proctoscopy can be performed (rare). 
This exam involves inserting a thin endoscope into the rectum to look inward. 
For example, worms take the form of small white filaments and can be seen in feces.

 

Treatment for intestinal parasites

Medications
The doctor chooses the most effective medicine against intestinal parasites. You may need only one dose or take this medicine for several weeks. 
For example, treat the worms with Pantelmin® (Mebendazole) .This medication is not recommended during pregnancy because many doctors do not know the possible effects on the fetus, especially in the first 12 weeks.

 

Diet and food against intestinal parasites

Parasites grow by eating especially some foods.

avoid:

  • Carbohydrates and sugars,
  • Dairy products,
  • Fruit juices,
  • Refined grains (like white rice).

The following foods are natural antiparasitic and allow the elimination of parasites, we recommend eating:

  • Raw garlic,
  • Seeds of pumpkin,
  • Romãs,
  • Beets,
  • Carrots.

In one study, the researchers found that a mixture of honey and papaya seeds eliminated feces parasites in 75% of subjects. 
Drink plenty of water to aid bowel activity.

 

Eating more fiber can help expel worms

Probiotics (Lactobacillus acidophilus, lactobacillus plantarum or Saccharomyces boulardii, bifidobacteria) help keep the digestive system healthy.

Digestive enzymes help restore normal bowel conditions so it becomes inhospitable to parasites.

The Papain is a papaya plant enzyme that can help kill the worms if you eat 30 minutes before or after meals.

 

Nutrition Supplements

The Vitamin C supports the immune system. 
Decrease the dose if you develop diarrhea.

Zinc (20-30 mg / day). 
This mineral helps the activity of the immune system. 
Zinc may interact with certain medications, especially antibiotics and may not be indicated in people with HIV / AIDS.

 

Natural remedies to eliminate intestinal parasites

1) Garlic
The Garlic (Allium sativa) is a good remedy against some worms as:

  • Ascaris lumbricoides,
  • Giardia lamblia,
  • Tripanossoma.

Garlic is available in the form of capsules and tablets or you can take the form of whole garlic cloves.

2) Goldenseal Goldenseal
herb (Hydrastis Canadensis) has been used historically for infections involving the mucous membranes of the body, such as respiratory tract infections. 
Preliminary laboratory studies have shown that Berberine (an active component of goldenseal) is active against:

  • Entamoeba histolytica,
  • Giardia lamblia.

3) Black Walnut Black
walnuts are a popular remedy used for ringworm and for the athlete’s foot. 
The juice of the black walnut green peel is used for:

There are clinical studies on the efficacy or safety of black walnut for intestinal parasites.

4) Absinthe
Absinthe (Artemisia annua) is an herb used for centuries as an herbal remedy for intestinal parasites. 
Preliminary research shows that absinthe may be useful against ascaris lumbricoides, Plasmodium, Schistosoma mansoni and Giardia. 
Absinthe contains the sesquiterpene lactones, it is believed that these substances weaken the parasite’s membrane.

You can take absinthe in the form of:

  • Tea,
  • Liquid extract (or mother tincture),
  • Capsule.

Pure oil is considered toxic and should not be ingested.

The safety and efficacy of this herb has not been proven in clinical studies.

5) Wormseed Wormseed
(Chenopodium ambrosioides) is an herbal remedy used in the tropics to expel:

  • Ascaris lumbricoides,
  • Tênias,
  • Cestódeos.

The concentrated wormseed oil is very powerful, so wormseed-based herbal tea is preferred. 
Further scientific studies are needed to confirm the historical use of this herb and its safety.

6) Pumpkin Seeds
Traditionally, pumpkin seed (Curcubita pepo) is used as a remedy for worms and ascaris lumbricoides.

Herbalists often recommend large quantities of pumpkin seeds, up to 25 grams for adults. 
The seeds are often crushed and mixed with the juice. 
The clinical safety and efficacy of pumpkin seeds has not been scientifically proven.

7) Orange Seed Extract
Generally, Orange Seed Extract is found in liquid form:

  • In health food stores,
  • In the herbal or manipulative pharmacy,
