Do You Have Intestinal Worms? Find Out With These Signs

Intestinal worms are parasites that live in the digestive tract and use the body as a source of nutrients. They can affect people of all ages, although some types are more common in children. Worm infections may cause no obvious symptoms at first, while others can lead to digestive problems, tiredness, itching, and changes in appetite.

Knowing the warning signs can help you seek the right medical advice instead of assuming that every stomach problem is caused by worms.

What Are Intestinal Worms?

Intestinal worms are parasitic worms that can enter the body through contaminated food or water, poorly washed produce, undercooked meat, or contact with contaminated soil and surfaces. Common types include roundworms, hookworms, whipworms, and pinworms.

The symptoms depend on the type and number of worms present. A mild infection may cause few or no symptoms, while a heavier infection can affect digestion and, in some cases, lead to nutritional deficiencies.

1. Persistent Abdominal Pain

Unexplained stomach pain or discomfort can occur with some intestinal worm infections. The pain may be mild and come and go, making it easy to mistake for indigestion or another digestive problem.

However, abdominal pain has many possible causes, so it should not automatically be linked to worms.

2. Frequent Diarrhoea Or Changes In Bowel Habits

According to a study published in the journal 'Therapeutic Advances in Gastroenterology', some worm infections can cause diarrhoea, loose stools, or changes in normal bowel habits. In other cases, people may experience constipation or alternating bowel changes.

Persistent diarrhoea, particularly when accompanied by weakness, weight loss, or dehydration, should be medically assessed.

3. Anal Itching, Especially At Night

Intense itching around the anus at night is a classic sign of pinworm infection. Female pinworms can move around the anus at night and lay eggs on the surrounding skin.

The itching may disturb sleep and can lead to repeated scratching. In children, restless sleep, irritability, or frequent waking may be noticeable.

4. Seeing Worms Or Worm-Like Material In The Stool

Sometimes, worms or parts of worms may be visible in the stool. Their appearance can vary depending on the type of parasite.

Not every string-like or pale substance in stool is a worm. Food fibres and mucus can sometimes look similar. If you notice something unusual repeatedly, speak to a doctor rather than trying to identify it yourself.

5. Unexplained Weight Loss

According to a study published in the Cureus Journal of Medical Science, some intestinal parasites such as the cecal pinworm can interfere with nutrient absorption or consume nutrients from food. This may contribute to unexplained weight loss, particularly when an infection is significant.

Losing weight without changing your diet or physical activity should always be investigated because it can have many causes.

6. Increased Tiredness Or Weakness

Certain worms, particularly hookworms, can cause blood loss from the intestine. A significant infection may contribute to iron-deficiency anaemia, which can cause tiredness, weakness, dizziness, headaches or pale skin.

Feeling tired does not mean you have worms, but persistent or unexplained fatigue warrants medical evaluation.

7. Changes In Appetite

Some people with intestinal worm infections may experience increased or reduced appetite. However, appetite changes are not specific to worm infections and can occur with many digestive, metabolic, and psychological conditions.

A persistent change in appetite accompanied by weight loss or other symptoms should be checked.

8. Nausea Or Vomiting

Some parasitic infections can cause nausea, vomiting, bloating, or other digestive symptoms. These symptoms are more concerning when they are persistent or occur alongside severe abdominal pain, weight loss, or changes in bowel habits.

9. Bloating And Excessive Gas

According to a study published in the journal 'Gastroenterology Clinics of North America', some people may experience abdominal bloating, gas, or discomfort during a parasitic infection.

However, these symptoms are very common and can also result from food intolerance, constipation, indigestion, or other gastrointestinal conditions.

Who Is More Likely To Get Intestinal Worms?

The risk can increase with poor hand hygiene, contaminated food or water, walking barefoot on contaminated soil, and eating undercooked meat or fish, depending on the parasite involved. Children may also be more exposed to pinworms because of close contact in homes, schools, and childcare settings.

Good hygiene can reduce the risk. Wash your hands with soap after using the toilet and before eating or preparing food. Wash fruits and vegetables thoroughly, drink safe water, and cook meat properly.

How Are Intestinal Worms Diagnosed?

Symptoms alone cannot confirm a worm infection. Depending on the suspected parasite, a doctor may recommend a stool examination or other tests. For pinworms, a tape test may sometimes be used to look for eggs around the anus.

Treatment depends on the type of worm. Doctors may prescribe specific anti-parasitic medicines, and the treatment may need to be repeated for certain infections.

When To See a Doctor?

Seek medical advice if you have persistent abdominal pain, ongoing diarrhoea, unexplained weight loss, blood in the stool, significant weakness, or persistent anal itching.

Severe abdominal pain, repeated vomiting, dehydration, or other sudden severe symptoms require prompt medical attention.

Final Word

Most intestinal worm infections can be treated effectively once identified. The key is not to self-diagnose based on one symptom. If several symptoms persist or you notice worms in your stool, speak to a healthcare professional for appropriate testing and treatment.
