Damage to the kidneys may give rise to decreased or absent urine production, usually 12 to 24 hours after the initial muscle damage.Swelling of damaged muscle occasionally leads to compartment syndrome—compression of surrounding tissues, such as nerves and blood vessels, in the same fascial compartment—leading to the loss of blood supply and damage or loss of function in the part(s) of the body supplied by these structures. Symptoms of this complication include pain or reduced sensation in the affected limb. A second recognized complication is disseminated intravascular coagulation (DIC), a severe disruption in blood clotting that may lead to uncontrollable bleeding. Causes
Any form of muscle damage of sufficient severity can cause rhabdomyolysis. Multiple causes can be present simultaneously in one person. Some have an underlying muscle condition, usually hereditary in nature, that makes them more prone to rhabdomyolysis. Genetic predisposition
Recurrent rhabdomyolysis may result from intrinsic muscle enzyme deficiencies, which are usually inherited and often appear during childhood. Many structural muscle diseases feature episodes of rhabdomyolysis that are triggered by exercise, general anesthesia or any of the other causes of rhabdomyolysis listed above.
It can be used to detect abnormalities such as those associated with pituitary tumors. Thyroid function tests: tests used to assess thyroid functioning by checking levels of thyroid-stimulating hormone (TSH), thyroxine (T4), and triiodothyronine (T3). Differential diagnoses
A variety of medical and psychological conditions have been misdiagnosed as anorexia nervosa; in some cases the correct diagnosis was not made for more than ten years. The distinction between binge purging anorexia, bulimia nervosa and Other Specified Feeding or Eating Disorders (OSFED) is often difficult for non-specialist clinicians. A main factor differentiating binge-purge anorexia from bulimia is the gap in physical weight. Patients with bulimia nervosa are ordinarily at a healthy weight, or slightly overweight. Patients with binge-purge anorexia are commonly underweight. Moreover, patients with the binge-purging subtype may be significantly underweight and typically do not binge-eat large amounts of food. In contrast, those with bulimia nervosa tend to binge large amounts of food. It is not unusual for patients with an eating disorder to "move through" various diagnoses as their behavior and beliefs change over time. Treatment
There is no conclusive evidence that any particular treatment for anorexia nervosa works better than others.Treatment for anorexia nervosa tries to address three main areas. Restoring the person to a healthy weight;
Treating the psychological disorders related to the illness;
Reducing or eliminating behaviors or thoughts that originally led to the disordered eating.In some clinical settings a specific body image intervention is performed to reduce body dissatisfaction and body image disturbance.
