Worm Infections in Adults: How to Know If You Have Them

When most people hear about worm infections, they immediately think of children. However, the truth is that adults are also at risk, especially in areas with poor sanitation, inadequate food safety protocols, or contaminated water sources.

Worm infections are not only unpleasant but they can also lead to life-threatening health complications if left untreated. The good news is, they’re preventable and treatable with the right knowledge and care.

What Are Worm Infections?

Worm infections (also known as helminth infections) are caused by parasitic worms that live inside the human body, usually in the intestines. These worms can enter your body in several ways: through contaminated food or water, direct contact with infected soil, or even through your skin.

The most common types of intestinal worms include:

• Roundworms (Ascaris lumbricoides): Spread by eating food or water contaminated with worm eggs from human waste.
• Hookworms: Can enter the body through the skin, often via bare feet on infected soil.
• Tapeworms: Contracted by eating raw or undercooked beef or pork.
• Whipworms (Trichuris trichiura): Spread by ingesting soil or food contaminated with infected faeces, common in areas with poor sanitation.

These parasites can remain dormant in your body for weeks or even monthsbefore symptoms appear.

Signs and Symptoms

Symptoms can vary depending on the type of worm and duration of the infection. Some people may show no signs at all, while others may feel unwell quickly.

Here are common signs of a worm infection:

• Persistent abdominal pain or bloating.
• Diarrhoea or, in some cases, constipation.
• Nausea or vomiting.
• Unexplained weight loss, even with a normal appetite.
• Fatigue or weakness.
• Itching around the anus, especially at night.
• Seeing worms or white segments in your stool.
• Skin rashes or allergic reactions.
• Anaemia (especially with hookworm infections).
• Poor nutrient absorption, despite a healthy diet.

If you’re experiencing several of these symptoms—especially after travelling, eating street food, or living in areas with poor sanitation—it’s a good idea to get checked.

Diagnosis and Treatment

Diagnosing a worm infection is relatively straightforward. A doctor will usually request a stool sample to look for eggs or adult worms. In some cases, a blood test or scan may be needed, especially if complications are suspected.

Treatment typically involves antiparasitic medications such as:

• Albendazole.
• Mebendazole.
• Praziquantel (especially for tapeworms or schistosomiasis).

These medicines are taken for a few days and are highly effective. In severe infections, a second round of treatment may be needed after a few weeks. In households where multiple people are at risk, doctors may advise treating everyone simultaneously to prevent reinfection.

Prevention: How to Protect Yourself

Preventing worm infections is easier than dealing with the symptoms. Here are some steps you can take to stay protected:

• Wash your hands with soap and water after using the toilet and before eating.
• Boil or treat drinking water if you’re unsure of its safety.
• Avoid eating raw or undercooked meat, especially pork and beef.
• Wear shoes when walking outdoors, especially in rural or muddy areas.
• Wash fruits and vegetables thoroughly before eating.
• Keep kitchens and bathrooms clean and hygienic.
• Consider deworming once or twice a year if you live in a high-risk area or have been exposed to parasites.

Final Thoughts

Worm infections are more common than many people realise, especially in environments where food, soil, or water may be contaminated. Left untreated, they can lead to fatigue, poor nutrition, and long-term health problems. But with early treatment and simple prevention, they’re easy to manage.
