Intestinal parasites are a very annoying disorder that causes a set of symptoms that make diagnosis difficult, since they can be confused with other ailments , such as:

  • Digestive problems
  • Nervousness
  • Changes in appetite
  • Increase or decrease in weight

Discover in this article all the symptoms that will help you to know if you suffer intestinal parasites.

What are intestinal parasites?

What are intestinal parasites?

The intestinal parasites are microorganisms that live in the intestine and that alter our bacterial flora , as well as the natural assimilation of nutrients and evacuation.

The most common are the following:

  • Giardias
  • Taenias
  • Amebas
  • Ascaris
  • Lamblias

In many cases the parasites that reach our body are excreted.

However, the toxins that accumulate in our body weaken the immune system. Thus, these parasites feed on these toxins and can grow and alter the place where they are.


How do I know if I have them?

The intestinal parasites are, in most cases, very difficult to detect, since as we have indicated previously, the symptoms can be confused with other pathologies or with simple discomforts.

That is why it is important to know these signs of the body that, if they remain without apparent cause, should help us find the cause .

Next, let’s review what these symptoms are. Some of them are very frequent and there are others that will surprise you. If you have questions, we recommend that you visit your doctor as soon as possible.

Digestive disorders

Digestive disorders

One of the most frequent symptoms of those who have intestinal parasites are frequent digestive disorders, with a predominance of diarrhea or constipation, gasand bloating.

The problem is that many people suffer from these annoyances and that, in addition, they can be due to different causes.

We must pay attention to them when we are feeding in a balanced way and, nevertheless, we continue to suffer from these disorders.

Appetite alteration

We can all have appetite changes for different reasons. However, this is one of the symptoms of parasitosis, when we suffer an excess or lack of exaggerated appetite and without knowing the cause .

This can lead to a rapid loss or weight gain too. We must, therefore, suspect intestinal parasites in these cases.

Nervousness and irritability


The intestinal parasites cause an important stress to our organism that reverberates, without our knowing it, in an alteration of the nervous system.

This causes an increase in our levels of nervousness , anxiety, irritability and stress. 

There are people who live frequently in these psychological states. However, when it is something unusual in those who suffer it, we must pay attention to other possible symptoms.

Nervousness can also be an important signal in children, who can suffer from hyperactivity. In them we can also see an increase in the pupils.


The itching in the area surrounding the anus and other body parts are also the signal that can have parasites. In addition, it is one of the most frequent reasons when it comes to infecting them, especially in children, who scratch themselves almost without us noticing.

Itching can also be frequent at the tip of the nose . This is one of the most curious and unknown symptoms and, although it has no scientific basis, we can take it into account along with others.

His explanation lies in the reflexological relationship between the tip of the nose and the intestine.

Chronic fatigue


Chronic fatigue and fibromyalgia are pathologies that have been recognized in the last decade and that gather a series of symptoms difficult to diagnose, since they can also be confused with other diseases.

Although the cause is unknown, intestinal parasites may be to blame for some of the symptoms suffered by affected people.


Vaginal infections

Women who suffer frequent vaginal infections should keep in mind that they may have intestinal parasites and that they are causing infection in the genital area.

For this reason, despite doing treatments that may seem effective in the short term, after a while they have the same discomfort.

The solution will be in the elimination of the parasites definitively and in strict hygiene measures.
