Parasites in Humans - Symptoms

Parasites are microscopic organisms that live in the body of the host. They depend entirely on the host for their nutrition and shelter. Some of them do not harm the host, but there are others that can cause a series of infections. Parasites can be of any size from the microscopic protozoa to the worms that can be seen with naked eyes. These parasites can live in any part of the body. Most of the individuals are affected by intestinal parasites or worms that live in the small or large intestine of the body. Parasites in humans symptoms are unlikely to be identified since it takes several weeks and even months for the signs of an infection to surface. Some of the most common types of parasites that affect human beings are tapeworms, liver flukes, ringworms, and heartworms etc. There are many media through which a parasite can enter the body. Contaminated food, water and polluted air are some of the common media from where the parasites enter a body and cause infections. Let's learn more about parasites in humans symptoms, the ways to prevent their infestation and methods of treating the symptoms. Also read about intestinal parasites symptoms.

Symptoms of Parasites in Humans

After the parasites enter the body, they release certain toxins that can cause several types of infections and health related disorders. The parasites that are present in the intestinal tract can cause inflammation of the inner lining or the mucosa membrane of the intestines. The toxins can also cause malfunctioning of certain organs like the kidneys and liver. Given below are some parasites in human symptoms:

    Allergies: The presence of certain parasites in the body can cause allergies. Some parasites irritate and perforate the inner lining of the intestinal tract, leading to intestinal permeability (also known as a leaky gut). The presence of these pathogens in the body leads to the over production of the body's defense cells called eosinophils. An excess of these fighter cells in the body can cause allergic reactions. The presence of these allergy producing parasites can also trigger the over production of immunoglobulin E (IgE), which is a type of antibody.
    Anemia: The presence of certain types of worms like taenia solium (tapeworm), ascaris lumbricoides (round worm) and liver flukes attach themselves to the mucosal membrane of the intestine and suck the nutrients from the body. If there are many worms present in the intestinal tract, then they also tend to suck blood causing iron deficiency anemia or perinicious anemia.
    Bloating and Gas: The inflammation caused due to the toxins, produced by the pathogens living in the small intestine can lead to a feeling of fullness or bloating and gas. This can also lead to the indigestion of high fiber foods like beans, vegetables and raw fruits. The symptom of this condition is a recurring distention of the abdomen. This symptom can last for a few months to many years till the parasites are completely eliminated from the body.
    Constipation: Some parasites are so large that they tend to block the intestinal passage restricting proper bowel movement. The infestation of worms can cause constipation, which can cause the elimination of waste materials from the body difficult and infrequent.
    Diarrhea: Certain protozoa like entamoeba histolytica can cause the over production of an enzyme called prostaglandin, which leads to the loss of sodium and chloride from the body. This condition can develop into diarrhea, or amoebiasis where the person may experience loose, watery stools. This condition may also lead to irritable bowel syndrome (IBS).
    Joint and Muscle Pain: The parasites tend to travel to other parts in the body and sometimes even in the muscles. This can lead to muscle stiffness, pain, irritation and inflammation of the joints.
    Skin Conditions: The toxins produced by the parasites can create allergic reactions on the skin like hives, weeping eczema and rashes etc. The infestation of protozoa can lead to dermatitis, swelling, sores and lesions on some parts of the body like face, area around the eyes, and feet.
    Other Symptoms: Some other parasites in human symptoms are tumors, sleep disorders, grinding of teeth, chronic fatigue syndrome, dysfunction of the immune system and nervousness etc.

Prevention and Treatment for Parasites Symptoms in Humans

In order to prevent infections, one must practice clean habits like washing hands and legs after coming from outside, using a disinfectant and drinking boiled water. Washing fruits and vegetables before consuming them is also a necessity to ward off any infections. For diagnosis, the doctor may tell you to undergo a magnetic resonance imaging (MRI scan) to detect the presence of worms. A stool sample may also be taken in case of intestinal worms. In case you are infected by parasites or protozoa, get some antibiotics and other drugs.

  1. It is no secret that I have a very deep and personal relationship with God. I have pushed and resisted that relationship this past year through all the bullshit I have had to go through living with Herpes but once again, God is bigger than my stubbornness and broke through that outbreak cold sore and all I had Genital Herpes. For me personally, hearing over and over how I am not good enough has really invaded my mind in the worst way possible. I completely shut down and I was just waking up like is this how life going to end this temporary herpes outbreak “fuck everybody with herpes if you know what I mean” but let's be honest here...It is a cowardly to say no to herbal medicine. It is fear based. And it is dishonest to what my heart wants. Don't build a wall around yourself because you are afraid of herbals made or taking a bold step especially when it's come to health issues and getting cure. So many young men/ women tell me over and over that Dr Itua is going to scam me but I give him a try to today I feel like no one will ever convince me about herbal medicine I accept Dr Itua herbal medicine because it's cure my herpes just two weeks of drinking it and i have been living for a year and months now I experience outbreak no more, You can contact him if you need his herbal medicine for any such diseases like, Herpes, Hepatitis, HIV, Epilepsy, Infertility, Love Spell,. Email..drituaherbalcenter@gmail.com then what's app.+2348149277967.... My advice to any sick men/women out there is simple... Be Always an open book. Be gut wrenching honest about yourself, your situation, and what you are all about. Don't hold anything back. Holding back will get you nowhere...maybe a one way ticket to lonelyville and that is NOT somewhere you want to be. So my final truth...and I'm just starting to grasp this one..
