All About Roundworms
Ascariasis, a disease caused by roundworms, is found in an estimated one-fourth of the world’s population, making this one of the most common types of parasitic infection.
Roundworms are especially common in developing countries, caused by poor sanitation and malnutrition. However, the world of roundworms encompasses thousands of species, of all sizes and temperaments. Thus, not all roundworms are necessarily parasites, but the ones that are can be a great nuisance.
What are Roundworms?
Roundworms are also known as “nematodes” and encompass several different species of parasitic worms that take up residence in the human body, particularly the intestines. At this date there have been up to 15,000 different varieties of roundworms identified, many acting as parasites in the human body. They can live in all types of climates but most frequently inhabit the soil or water of humid, tropical areas.
Common Types of Parasitic Roundworms
- Hookworms
- Pinworms
- Ascarids
- Whipworms
Signs and Symptoms
Though extremely prevalent, it can at times be difficult for an individual to know if he or she has contracted roundworms. Oftentimes there are no symptoms. If prevalent, symptoms can be wide-ranging and of a general nature. In the event that a person is experiencing one or more symptoms, diagnostic tests are recommended, particularly if there has been recent travel to a tropical climate.
- Abdominal pain
- Chronic cough
- Bloody stools
- Weight loss
- Fatigue
- Itchy rash
- Loss of vision
Infections caused by roundworms can cause the intestines to become inflamed and painful, and can lead to a reduction in the body’s ability to absorb nutrients properly. This can lead to general feelings of ill-health, caused by malnutrition. In serious cases, bowel movements can be obstructed and lead to death.
Risk Factors
Although roundworms can be contracted by people of all ages and walks of life, certain environmental conditions or lifestyle behaviors can make a person more susceptible to potential infection.
- Poor sanitation practices
- Poor personal hygiene
- Insect bites
- Living in or visiting tropical climates
- Malnutrition
- Eating undercooked meat
- Soil contamination
Avoiding these risk factors may be the best way to prevent roundworms. However, in the event that infection does occur, fortunately there are treatments available.
Treatments
The first step towards treatment if roundworms are suspected is diagnosis and confirmation of the infection. Worms may pass through the mouth or anus, in which case they should be brought to a doctor for inspection. A doctor may also conduct blood tests and stool samples, among other exams, to check for the presence of roundworms.
Once identified, roundworms can be battled with anti-parasite medications, thorough colon cleansing, or surgery if necessary. In addition, a balanced diet and certain foods can help prevent the invasion of roundworms.
Dietary Tips to Combat Roundworms
- Avoid refined foods, sugar, and white breads
- Bitter and spicy foods (chili peppers, ginger, turmeric) may repel roundworms
- Drink 6-8 glasses of clean, filtered water per day
- Take vitamin A supplements
- Eat less meat, especially pork, and make sure it is well-cooked
