What happens to the spleen as the body ages?

As the body ages, the spleen typically undergoes atrophy, which means it gradually shrinks in size and potentially reduces in weight and function. This atrophy can affect the immune system, as the spleen plays a critical role in filtering blood and producing lymphocytes, which are vital for immune response.

The aging process often leads to a decrease in immune function, making older adults more susceptible to infections and other health issues. While some organs may enlarge or become more active with age due to various reasons, the spleen does not follow this pattern, emphasizing the unique changes that occur in this organ. Understanding the atrophy of the spleen with aging is important for recognizing potential health challenges in elderly patients and how that may influence treatment and care strategies.
