Whipworm infection usually happens due to accidental swallowing of microscopic eggs. The sources can be contaminated soil, food, or water. Although a mild infection may not cause any symptoms, a heavier infection can cause abdominal symptoms. Our experts explain how early assessment can help you receive appropriate care during pregnancy.

Whipworm is a type of intestinal parasite. It may infect you after you swallow its eggs accidentally. The eggs may reach your intestine through contaminated soil, impure water, unwashed vegetables, and eating food without thoroughly washing your hands. This infection is most prevalent in areas where sanitation is poor. Once inside your body, the worms mature in the large intestine.

With mild whipworm infection, you may not always experience noticeable symptoms. However, if the infection is severe, you may experience abnormal bowel movements and poor nutritional status.

During pregnancy, abdominal discomfort or changes in bowel habits do not necessarily mean you have an infection. Various pregnancy-related physiological changes happening in your body may cause similar symptoms. If any persistent symptoms occur, inform your doctor at your antenatal visit.


What Are the Symptoms of Whipworm Infection During Pregnancy?

Many people with a mild infection have no symptoms. When the worm burden is higher, you may notice:

  • Diarrhoea
  • Abdominal pain or discomfort
  • Nausea
  • Reduced appetite
  • Weakness or tiredness
  • Blood or mucus in the stool in more severe infections
The symptoms can overlap with other digestive problems. Therefore, symptoms alone cannot confirm a whipworm infection.

Can Whipworm Cause Anaemia During Pregnancy?

Whipworm may affect your nutritional health, particularly when the infection is heavy. However, hookworm infection is more closely linked with the following:

  • Chronic intestinal blood loss
  • Iron-deficiency anaemia
On the other hand, a heavy whipworm infection may lead to inflammation of the intestines, diarrhoea, and, in some cases, blood in the stools. If you already have anaemia during pregnancy, your doctor might consider stool and blood testing if they suspect such a parasitic infection may be the reason for your condition.

How Is Whipworm Infection Diagnosed During Pregnancy?

Your doctor may recommend a stool examination to look for whipworm eggs. The test can help confirm an intestinal worm infection. If you also have symptoms of anaemia, your doctor may recommend a blood test to check your haemoglobin level.

Your doctor may consider:

How Can You Prevent Whipworm Infection During Pregnancy?

Whipworm spreads when you swallow infective eggs from contaminated soil, food, or water. You can reduce your risk by following good hygiene and food-safety practices.

  • Wash your hands before eating and after using the toilet.
  • Wash vegetables and fruits thoroughly before eating them.
  • Cook food properly.
  • Drink safe water.
  • Use toilets and avoid contact with soil contaminated with human faeces.
  • Keep your surroundings clean.
  • Follow your antenatal care plan.
If you have persistent diarrhoea, abdominal pain, weakness, or blood in your stool, speak to your doctor rather than self-treating.

You may have a whipworm infection during pregnancy without experiencing any symptoms. If you experience persistent symptoms, a timely medical assessment can help confirm the infection and guide safe treatment during pregnancy.
