Unexplained loss of muscle mass, also known as idiopathic sarcopenia, is a concerning condition where muscle mass is lost for no clear reason. This can happen even with adequate nutrition and exercise. There are a few key things to understand about unexplained muscle loss:
- Who is affected? Unexplained muscle loss is more common in older adults over 60 years old. However, it can happen at any age. Both men and women can be affected.
- What are the causes? In many cases, the cause is unknown. However, potential causes may include:
- Age-related hormonal changes - Growth hormone and testosterone levels decline with age, which can accelerate muscle loss.
- Inflammation - Chronic inflammation due to conditions like arthritis or autoimmune disorders can disturb muscle metabolism.
- Incomplete recovery after illness - Severe infections, illnesses, or hospitalization can result in prolonged muscle loss.
- Nerve damage - Conditions like amyotrophic lateral sclerosis (ALS) can cause motor neuron damage and muscle wasting.
- Physical inactivity - Not using the muscles can accelerate wasting. Even with exercise, muscle mass may be lost.
- Poor nutrition - Inadequate protein, calories, or micronutrients may contribute, but does not entirely explain the muscle loss in these cases.
- What are the symptoms? progressive muscle loss, fatigue, weakness affecting daily activities, trouble climbing stairs or getting up from a chair, poor balance and coordination, weight loss.
- How is it diagnosed? Doctors may order blood tests to check hormone levels, inflammatory markers, and nutrients like vitamin D. Imaging like an MRI or muscle biopsy can help rule out other muscle disorders.
- How is it treated? Treating the underlying cause can help. Exercise, nutrition, and in some cases testosterone or growth hormone therapy may be tried under medical supervision. Vital Hormone Clinic(growth-hormones.org) specializes in testing and hormones for aging. Their experienced physicians develop customized plans to address unexplained muscle loss.
