muskelnedgång

Muskelnedgång, also known as muscle atrophy, refers to a decrease in the size of muscle tissue. This loss of muscle mass can be due to a variety of factors, including disuse, aging, malnutrition, and certain medical conditions. When muscles are not used regularly, the body begins to break them down as they are not essential for immediate survival. Aging naturally leads to sarcopenia, a progressive loss of muscle mass and strength. Insufficient protein intake or overall calorie deficiency can also prevent the body from maintaining muscle tissue.

Several diseases can cause muscle atrophy, such as muscular dystrophy, neurological disorders like ALS, and chronic illnesses that lead to inflammation or metabolic changes. The symptoms of muscle atrophy include reduced muscle size, weakness, and a feeling of heaviness or fatigue in the affected limbs. In severe cases, it can impact mobility and daily functioning. Diagnosis typically involves a physical examination, medical history, and sometimes imaging tests like MRI or EMG to assess muscle health and nerve function.

Treatment for muscle atrophy depends on the underlying cause. If it's due to disuse, physical therapy and exercise are crucial to regain muscle mass. Nutritional support, particularly adequate protein intake, is also important for muscle repair and growth. For muscle atrophy caused by disease, managing the underlying condition is the primary focus, often alongside therapies to preserve muscle function and strength. Early intervention and consistent management are key to mitigating the effects of muscle nedgång.
