Parasites can affect your body in ways you might not expect. These tiny organisms need a host (like a human body) to survive, and they do this by taking nutrients from the foods you eat. Think of them as uninvited guests who eat at your table without contributing anything in return.

Here’s how parasites can impact your overall health:

  • They compete for your nutrients Parasites live off the food you eat, taking essential nutrients before your body can absorb them. This can leave you feeling tired and lacking important vitamins and minerals your body needs.
  • They affect your digestive system – These organisms can change how well your intestines work. When they attach to your intestinal walls, they can make it harder for your body to process and use the food you eat properly.
  • They drain your energy – Since parasites take nutrients from your body and make your immune system work harder, you might feel more tired than usual. Many people report feeling exhausted even after getting enough sleep.
  • They can work quietly – One of the trickiest things about parasites is that they often don’t cause obvious problems right away. They might be affecting your health for weeks or months before you notice any changes.
