Why Does It Happen—and to Whom?
Muscle mass naturally starts to decline from the age of 30 (yes, that early!), but the process accelerates significantly around 60. The causes are multiple, often overlapping:
1. Time Passing
With age, hormones that support muscle growth—such as IGF-1 and growth hormone—decline. Recovery after activity is slower, nutrient absorption less efficient, and the body overall becomes less resilient.
2. Lifestyle Habits
Daily habits can either strengthen or weaken muscles. Skipping meals, eating too little protein, avoiding physical activity, or sitting for long periods all accelerate muscle decline. Sedentary behavior is the number one risk factor. Add to this a widespread vitamin D deficiency, which impairs muscle tone, and the problem grows.
3. Underlying Conditions
Certain medical issues silently worsen sarcopenia. Diabetes, thyroid disorders, chronic inflammation, and neurological conditions can all accelerate muscle loss—sometimes without obvious symptoms.
