Premise: How to know if you have worms<br>Keep track of any unexplained weight loss. When you have worms in your body, you get less nutrients than you are used to because the worm is consuming these nutrients. You may therefore begin to lose weight because while you are eating like normal, your body is not absorbing the calories and nutrients that it should because the worm is taking them from you.
Hypothesis: If you have not lost weight you do not have worms.
