Understanding Sarcopenia and GLP-1 Medications

The term sarcopenia, meaning poverty of flesh, is crucial in discussing the effects of GLP-1 medications, particularly in older adults. These medications can lead to significant weight loss, with estimates suggesting that nearly half of the total weight lost can come from muscle. This is concerning, especially for individuals aged 40 and above, as they are already at a higher risk for muscle loss due to aging. The implications of muscle loss for strength, health, and overall quality of life are still being researched, highlighting the need for caution when using these medications.
