Several glands experience changes in size or function with age. While not all glands increase in size, some show increases in volume or experience hyperplasia (increased cell number).
Glands Showing Age-Related Increases
-
Parathyroid Glands: Parathyroid hormone levels, produced by the four parathyroid glands located near the thyroid, rise with age. This increase may contribute to conditions like osteoporosis. [Source: Parathyroid hormone levels rise with age, which may contribute to osteoporosis. 21-Jul-2022] A study also shows that parathyroid gland volume increases with age, starting as early as 6-12 months and becoming three times larger by 28 months.

Prostate Gland: In males, the prostate gland often enlarges with age, leading to benign prostatic hyperplasia (BPH). While not solely an increase in gland size, this enlargement is linked to aging processes and hormonal changes. [Source: Age increases the risk of prostate problems, such as BPH and prostate cancer. ... https://www.cancer.gov/types/prostate/understanding-prostate-changes; Factors linked to aging and changes in the cells of the testicles may have a role in the growth of the gland, as well as testosterone levels. https://medlineplus.gov/ency/article/000381.htm]
Important Note:
It's crucial to understand that aging affects various glands differently. Some experience a decrease in function, others experience changes in hormone production, and some, as detailed above, show increases in size or hormone levels.
