The Thyroid Gland One cause is the cancer itself. For example, in an effort to fight the cancer, the body produces substances called cytokines. These substances can lead to weight loss, muscle loss, and a decrease in appetite. Another common cause is the treatments for cancer. Radiation and chemotherapy often cause a decrease in appetite. They can also lead to side effects such as nausea, vomiting, and mouth sores, which can affect your ability to eat normally, further contributing to weight and muscle loss.

muscle tone Pathologically, loss of tone (flaccidity) can be caused, e.g. by peripheral nerve damage, and exaggerated tone (spasticity) by overstimulation, e.g. when the activity of the relevant lower motor neurons is released from higher CNS control in spinal injury.

Muscle Weakness Muscle weakness is commonly due to lack of exercise, ageing, muscle injury or pregnancy. It can also occur with long-term conditions such as diabetes or heart disease. There are many other possible causes, which include stroke, multiple sclerosis, depression, fibromyalgia and chronic fatigue syndrome (ME).

Muscle Science Muscles shrink and weaken if they are not exercised. Muscle loss also occurs in certain diseases, and it is an inevitable consequence of aging. Age-related muscle loss, or sarcopenia, affects 40 percent of people who are age 80 or older.

Weakness and Fatigue - Topic Overview Muscle weakness that is slowly getting worse requires a visit to a doctor. Sudden muscle weakness and loss of function in one area of the body can indicate a serious problem within the brain (such as a stroke or transient ischemic attack) or spinal cord or with a specific nerve in the body.

- Loss of muscle function is often caused by a failure in the nerves that send signals from the brain to the muscles, causing them to move. Muscle function tends to occur in what are called voluntary muscles. Voluntary muscles are skeletal muscles that you have full control over.

Weight Loss: Symptoms & Signs Symptoms & Signs. Weight loss can be intentional, such as from dieting and exercise, or unintentional and be a manifestation of illness. Weight loss can result from a decrease in body fluid, muscle mass, or fat. A decrease in body fluid can come from medications, fluid loss, lack of fluid intake, or illnesses such as diabetes.

- Other common causes of disuse atrophy include medical conditions that decrease mobility, such as rheumatoid arthritis (chronic autoimmune disease characterized by joint inflammation) or osteoarthritis (thinning and weakening of the bones), and injuries, such as broken bones and burns.njuries or trauma to nerves due to spinal cord injury, burns, or stroke can also lead to muscle atrophy. Depending on the cause, atrophy may occur in one muscle, a group of muscles, or the entire body, and it may be accompanied by numbness, pain or swelling, as well as other types of neuromuscular or skin symptoms.

Muscle atrophy Muscle mass is reduced as muscles atrophy with disuse. Muscle atrophy occurs by a change in the normal balance between protein synthesis and protein degradation. During atrophy, there is a down-regulation of protein synthesis pathways, and an activation protein degradation.

- Muscle atrophy can also happen if you are bedridden or unable to move certain body parts due to a medical condition. Astronauts are subject to some muscle atrophy after a few days of weightlessness. Other causes for muscle atrophy include: 1  lack of physical activity (for any reason). 2  aging. 3  alcohol-associated myopathy (pain and weakness in muscles due to excessive drinking over long periods of time). 4  burns. 5  injuries and broken bones. 6  malnutrition.

Muscle atrophy Muscle atrophy results from a co-morbidity of several common diseases, including cancer, AIDS, congestive heart failure, COPD (chronic obstructive pulmonary disease), renal failure, and severe burns; patients who have cachexia in these disease settings have a poor prognosis. Moreover, starvation eventually leads to muscle atrophy.

What Is Muscle Atrophy? So, what is muscle atrophy and what can be done to reverse it? Muscle atrophy is the loss or decrease of muscle mass. The synonyms for it are muscle wasting, muscle loss, muscle catabolism, muscle withering. The cause of muscle atrophy are a lack of use of the muscle or a disruption of the nerve signals to the muscle. It is seen in many conditions, especially with cachexia in cancer and HIV/AIDS. The cure for muscle atrophy is using the muscle, most easily through exercise and being active in normal daily activities.

Muscle Weakness Lack of use. Lack of muscle fitness (deconditioning) is one of the most common causes of muscle weakness. It may occur as a result of an inactive (sedentary) lifestyle. If muscles are not used then the fibres within the muscles are partially replaced with fat.

What Causes Leg Muscle Atrophy? The most common reason for atrophy to occur in the legs is disuse. Lack of activity for any reason -- illness, injury, seated desk job, sedentary lifestyle -- can lead to loss of leg muscle. Alcoholism and malnutrition can also inhibit muscle growth and cause the body to use muscle proteins for energy.

Evaluation of the Patient with Muscle Weakness Muscle weakness, or myasthenia, is a decrease in strength in one or more muscles. It is a common symptom of muscular, neurological and metabolic disorders. Muscular diseases, such as muscular dystrophy and dermatomyositis (disorder characterized by muscle inflammation), are common causes of muscle weakness.ther possible causes of muscle weakness include paralytic shellfish poisoning, botulism, and low levels of potassium in the blood. Depending on the cause, weakness may occur in one muscle, a group of muscles, or all the muscles, and it may be accompanied by pain, atrophy, cramping, or other types of muscular symptoms.

Muscle Atrophy Also known as: Muscle wasting, Wasting or Atrophy of the muscles. Definition. Muscle atrophy is the wasting or loss of muscle tissue. Causes. There are two types of muscle atrophy: disuse and neurogenic. Disuse atrophy is caused by not using the muscles enough. This type of atrophy can often be reversed with exercise and better nutrition.

- Muscle atrophy is when muscles waste away. The main reason for muscle wasting is a lack of physical activity. This can happen when a disease or injury makes it difficult or impossible for you to move an arm or leg. You may have muscle loss if one of your limbs appears smaller (not shorter) than the other.Schedule a physical exam to determine the cause of the loss. Your doctor will determine what treatment you need.his can happen when a disease or injury makes it difficult or impossible for you to move an arm or leg.

Muscle atrophy Disuse of the muscles, such as when muscle tissue is immobilized for even a few days of unuse – when the patient has a primary injury such as an immobilized broken bone (set in a cast or immobilized in traction), for example – will also lead rapidly to disuse atrophy.n addition to the simple loss of muscle mass (atrophy), or the age-related decrease in muscle function (sarcopenia), there are other diseases which may be caused by structural defects in the muscle (muscular dystrophy), or by inflammatory reactions in the body directed against muscle (the myopathies).
