Sarcopenia is the progressive loss of muscle mass, strength, and function that often occurs with aging. While some muscle loss is a normal part of getting older, severe muscle loss can affect mobility, balance, independence, and overall health.
What Causes Sarcopenia?
1. Aging
Beginning around age 30–40, people gradually lose muscle mass. The process often accelerates after age 60.
2. Physical Inactivity
Muscles need regular use to stay strong. Long periods of inactivity, bed rest, or a sedentary lifestyle can speed up muscle loss.
3. Inadequate Protein Intake
Muscles require protein to maintain and repair themselves. Insufficient dietary protein can contribute to muscle wasting.
4. Chronic Illness
Conditions such as:
- Type 2 Diabetes
- Heart disease
- Chronic kidney disease
- Certain cancers
can increase the risk of sarcopenia.
5. Hormonal Changes
Lower levels of hormones such as testosterone, estrogen, and growth hormone may contribute to declining muscle mass.
6. Inflammation
Chronic low-grade inflammation, which becomes more common with age, may accelerate muscle breakdown.
