Roundworms do not die on their own, and they multiply if left untreated. Ascaris is an intestinal parasite that absorbs glucose from the body through the intestinal wall during its lifetime to sustain itself. Since nutrition in the human intestine is constantly present, roundworms do not have the possibility of starvation and will multiply in the process of intestinal parasitism, and some people will even suffer from incomplete intestinal obstruction due to roundworms forming a mass when they multiply. Ascaris can survive in the intestine for about a year, and will die after reaching a certain level of life expectancy, but during this year will multiply offspring, causing health effects on the patient. Once the presence of roundworms in the intestine is detected, treatment with anthelmintic drugs such as mebendazole and albendazole should be chosen as soon as possible.
