Can Worm Infections Go Away on Their Own?

A few mild infections might resolve on their own over time, but many intestinal worm infections require treatment.

Why Should You Not Wait?

  • There could be deficiencies in your body’s nutrients.

Treating vs Waiting

Risk of Delaying Treatment

A delay may lead to a persistent infection.

  • Disruption of sleep
  • Reinfection

Prompt treatment may help address these problems.

  • Changing bed linens often
  • Washing clothes in warm water

  • Should my relatives also get treated?
  • How can I avoid reinfection?

These conversations can serve as helpful guidelines for treatment.
