Answer:

Osteoporosis

Step-by-step explanation:

Osteoporosis is a more common condition in women over 45 that leaves bones fragile and porous. As it progresses with advancing age, the disease increases the risk of fractures, especially in the wrist, spine and hips.

The structure of our skeleton lives in constant renewal. We gain bone mass by age 20 and lose more quickly after 40. Two types of cells - osteoclasts and osteoblasts - are involved in the bone renewal cycle. Osteoclasts promote the absorption of minerals, eliminating areas of bone tissue and creating cavities.

Osteoblasts, in turn, are in charge of filling these cavities, producing new bones. For this they use calcium, absorbed with the help of vitamin D. Thus, every three months 10% of the skeleton renews itself.
