Tapeworm: Symptoms, Causes, Diagnosis, Prevention & Treatments post thumbnail image

Tapeworms are flat-shaped worms that live in the intestines of animals. People can be affected by tapeworms by eating the undercooked meat of infected animals. Animals will be infested with the parasite while grazing or drinking contaminated water. There will be few symptoms in human beings and the infestation can be treated very easily. However, if the treatment is not provided in time, it will lead to a life-threatening issue. You should be aware of the symptoms and should undergo the right treatment to overcome the infection.

Symptoms of Tapeworm:

It is not very uncommon that most tapeworm-infected people will not show symptoms. If you are suffering from an infection, the symptoms will depend on the type of tapeworm that you are affected by. If you are suffering from invasive tapeworm, the symptoms are based on the location (or presence) of the larvae in the body.

Symptoms of intestinal infection

–  Nausea

–  Diarrhoea

–  Abdominal pain

–  Loss of appetite

–  Dizziness

–  Craving for salt

–  Weight loss

–  Difficulty in absorbing the nutrients from the body

–  General weakness

Symptoms of invasive infection

The invasive infection will take place if the larvae migrate to other parts of the body from the intestines. It will lead to the formation of cysts. In this process, either the tissue or the organ damage will take place.

The following symptoms are prominent:

–  A headache

–  Mass or lump

–  Allergic reaction

–  Seizures

–  Neurological symptoms

Tapeworm Causes:

You should be aware of the causes of tapeworm infestation. The infestation is caused by either eggs or larvae.

– Infestation through eggs – If the food or water source is contaminated with the faeces of the infected person or animal, you will contact the tapeworm infection.

The faeces released by the animal may be contacted by the food or water source. As you eat the infected food, you will get the infection.  If the eggs are inside the intestine, they may travel to other parts of the body, and the formation of cysts will take place. For example, cysts may be formed in the liver, lungs, and other organs of the body.

– Infestation through larvae – The infestation may also take place through the larvae. If an animal is infected with tapeworm, the larvae will be present in its tissues. The larvae will be ingested into your body if you eat the undercooked meat of the infected animal. The larvae will develop into adult tapeworm when you eat the meat. The length of the adult tapeworms will be more than 25 meters. They have the capability to survive for up to 30 years in the human body. Some tapeworms will be attached to the intestines and some will be exit through the stool.

What are the risk factors of Tapeworm?

You should be aware of the causes and risk factors of tapeworms.

–  Poor personal hygiene – The contaminated water may reach your mouth due to infrequent washing or bathing.

–  Exposure to animals – If you are living in an area where human and animal faeces are not being disposed of properly, there will be a great risk of contamination.

–  Poor sanitation practices – If you travel to countries where the sanitation practices are poor.

–  Raw eggs and uncooked meat – The risk perception is high by eating raw eggs or uncooked meat or semi-cooked meat.

What are the complications of Tapeworm?

You should be aware of the symptoms of tapeworm infestations and the complications arising out of the infestation.

– Blockage of the appendix – If the size of tapeworms is high they can block the appendix. It is an infection that should be attended to on an emergency basis. The infection may affect the bile duct or pancreatic duct. The bile duct will carry the bile to the intestines.

– Impairment of brain and central nervous system – There will be a headache and visual impairment through the presence of poke tapeworm. The other issues that lead to serious health complications include seizures, dementia, meningitis, and visual impairment. If the infection is severe it will lead to death as well.

– Disruption of organ function – The functioning of various organs such as the liver and lungs will be affected by the formation of cysts. If the cysts are large enough, it will lead to the restricted blood supply. It may lead to additional cysts as well with the rupture of larvae. There will be an allergy-like situation with the rupture or leakage of the cyst. The other symptoms include itching, hives, swelling, and difficulty in breathing. If the issue is severe, it will lead to breathing difficulty and surgery as well.

Diagnosis of Tapeworm:

The diagnosis of tapeworms will be done through blood tests, stool tests, and certain kinds of scans. The signs and symptoms are prominent in the eyes, muscles, and brain.

– Blood test – The antibodies should produce to fight the tapeworm infestation in the best possible way. It can be checked through a blood test.

– Imaging systems – By applying the imaging solutions such as CT scans, MRI scans, X-rays, or ultrasounds of cysts, it is possible to figure out the tapeworm infection.

– Stool sample – The doctor will check the stool and a stool sample will be sent to the lab. The presence of eggs or larvae will be identified through microscopic examination. As the passage of eggs will be different at various points in time, it is necessary to conduct tests at various intervals. The patient might want to go through two or more tests as well. A transparent adhesive might be pasted to the anus to collect the eggs in a very efficient manner.

Tapeworm Treatments:

– Without medication – In most cases, no specific treatment is required to overcome the tapeworm in infection. The tapeworms will be expelled from the body automatically.

– With medication – If you are affected by tapeworms, you can undergo the medication through which the infection can be overcome very easily. The medication is based on the type of tapeworm and the area of infestation.

– Oral medication – The following oral medication will be prescribed by doctors to overcome adult tapeworm infection:

–  Biltricide

–  Albenza

–  Alinia

The above drugs are used to treat adult tapeworms.

– Sample test after the treatment – The doctor will suggest a test after undergoing the medication. If the stool is free from tapeworm eggs, larvae or proglottids, it will be concluded that you are free from tapeworms.

– Albendazole (Albenza) – By using Anthelmintic drugs, the cysts’ size will diminish. The assessment will be done by undergoing an ultrasound or X-ray test.

– Corticosteroid medication – To reduce the inflammation of cysts or organs, the doctor may suggest corticosteroid medication such as prednisone or dexamethasone.

– Anti-seizure drugs – If the patient is suffering from seizures, the doctor will prescribe anti-epileptic medication.

– Shunt – The placement of the permanent tube in the head is called a shunt. The tube will be used to drain the excess fluid formed in the brain.

– Surgical procedure – If the organ function is affected it will be handled by the surgical procedure. The most possible organs affected by surgery include the eyes, liver, and lungs.

As prevention is better than cure, you should take all possible steps to avoid tapeworm infestations.

Myth #1: It is not possible to expect a full recovery

It is possible to expect a full recovery in a few days to a few weeks. If the infection is severe, the recovery period will belong. If you manage a poor immune system, the recovery rate will be slow. People suffering from existing health conditions will take more time than healthy people to recover from the infection.

Myth #2: You can stop the medication if you feel better

After starting the medication, you should continue the same until the completion of the course. Even though you feel better after using the drug for a few days, the course should not discontinue. Even though the medication goes for several weeks, you should not stop abruptly.

Myth #3: Endoscopy cannot be applied

If the doctor finds it difficult to trace the presence of tapeworm through the stool test or X-ray, the endoscopy or colonoscopy will be suggested. The other causes of symptoms can be eliminated in the best possible way.

Myth #4: Tapeworms will not spread by drinking contaminated water

Tapeworm infection will spread by drinking contaminated water or food. Hence, you should opt for food prepared in hygienic conditions. The source of food, water, and the preparation process will also play a huge role in spreading the infection.

Myth #5: You are not required to wash your hands after using the toilet
