Which of the following is a consequence of leukopenia?

Leukopenia is characterized by a reduced number of leukocytes, or white blood cells, in the body. White blood cells play a crucial role in the immune system by defending the body against infections and diseases. When the level of these cells drops, the body's ability to fight off pathogens is significantly impaired, leading to an increased susceptibility to infections. This condition makes it difficult for the immune system to respond appropriately, resulting in a higher likelihood of developing infections from bacteria, viruses, or other pathogens.

The other options do not directly correlate with leukopenia. While anemia involves a deficiency in red blood cells, it is not a direct consequence of leukopenia. Enhanced blood clotting is generally unrelated to white blood cell counts and can have other causes, such as platelet disorders. Weight gain does not have a direct link to leukopenia and could be influenced by a variety of other factors. Therefore, the consequence of increased risk of infections is the most accurate outcome associated with leukopenia.
