Modifications of the organism

Old age is a stage of life that generally begins around the age of 65 and is characterized by a series of changes in the body. These changes affect various aspects of the health and well-being of older people. In this session, we will explore in detail the changes in the body that occur during old age.

Physical Changes

Loss of Muscle Mass: One of the most significant physical changes in old age is the loss of muscle mass, known as sarcopenia. This can lead to decreased strength and mobility, which in turn increases the risk of falls and injuries.

Changes in the Respiratory System: Lung function may be reduced, which can make it more difficult to breathe and adequately oxygenate the body.
