lihasatrofiat

Lihasatrofia, often referred to as muscle atrophy, is a medical condition characterized by the wasting or loss of muscle tissue. This can occur due to a variety of reasons, most commonly prolonged inactivity or disuse of the muscles. When muscles are not regularly used, the body begins to break down muscle protein, leading to a decrease in muscle size and strength.

Another significant cause of muscle atrophy is neurological damage. Conditions affecting the nerves that control muscles, such as spinal cord injuries, stroke, or certain neuromuscular diseases like amyotrophic lateral sclerosis (ALS), can lead to muscle wasting because the nerve signals necessary for muscle contraction are disrupted. Age-related muscle loss, known as sarcopenia, is also a form of atrophy that occurs naturally as people age, resulting in a gradual decline in muscle mass and function.

Nutritional deficiencies can also contribute to muscle atrophy, particularly a lack of protein, which is essential for muscle repair and maintenance. In some cases, muscle atrophy can be a symptom of underlying medical conditions or a side effect of certain medications. The symptoms of muscle atrophy typically include a noticeable decrease in the size of the affected muscle, weakness, and reduced range of motion. Treatment and management strategies depend on the underlying cause and may involve physical therapy, exercise, nutritional support, or addressing the primary medical condition.
