Hookworms are known to cause which of the following health issues?

Hookworms are parasitic worms that primarily affect humans and animals by attaching themselves to the intestinal wall and feeding on the host's blood. This feeding behavior can lead to a significant decrease in red blood cell count, resulting in anemia. Anemia caused by hookworms is due to the loss of blood and the body’s inability to produce enough red blood cells to replace those lost, which can lead to symptoms like fatigue, weakness, and paleness.

While skin infections, digestive issues, and respiratory problems can arise from various other conditions or parasites, they are not the primary health issues associated with hookworm infestations. The direct result of blood loss and nutritional deficiencies caused by these parasites places anemia as the most relevant health concern associated with hookworms. Understanding this relationship helps in recognizing and treating the effects of hookworm infections promptly.
