Amongst patients admitted to intensive care units (ICUs), hypoalbuminemia is specifically associated with ICU-acquired muscle weakness. [14] In chronic kidney disease, hypoalbuminemia is an indicator of frailty, which is itself associated with complications, mental distress, quality of life impairment, resource utilization, and mortality.

Weakness is a symptom of many different medical conditions. [1] The causes are many and can be divided into conditions that have true or perceived muscle weakness. True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy .
True muscle weakness is a primary symptom of a variety of skeletal muscle diseases, including muscular dystrophy and inflammatory myopathy. It occurs in neuromuscular junction disorders, such as myasthenia gravis. Muscle weakness can also be caused by low levels of potassium and other electrolytes within muscle cells. It can be temporary or ...
Typically, the weakness and fatigue are worse toward the end of the day. [17] Myasthenia gravis generally starts with ocular (eye) weakness; it might then progress to a more severe generalized form, characterized by weakness in the extremities or in muscles that govern basic life functions. [18]
Disuse is a common cause of muscle atrophy and can be local (due to injury or casting) or general (bed-rest). The rate of muscle atrophy from disuse (10–42 days) is approximately 0.5–0.6% of total muscle mass per day although there is considerable variation between people. [5]
Rhabdomyolysis (shortened as rhabdo) is a condition in which damaged skeletal muscle breaks down rapidly, often due to high intensity exercise over a short period. [6] [4] [5] Symptoms may include muscle pains, weakness, vomiting, and confusion.
The Fried Frailty Phenotype assesses five domains commonly affected by frailty: exhaustion, weakness, slowness, physical inactivity, and weight loss. The presence of 1-2 findings is classified as "pre-frailty", 3 or more as frailty and the presence of all 5 indicates "end-stage frailty" and is associated with poor prognosis. [ 11 ]
Weakness (motor deficits) occurs in generalized fashion, rather than beginning in one region of the body and spreading. Limb and respiratory (diaphragm) muscles are especially affected. The muscles of the face are usually spared, but in rare cases, the eye muscles may be weakened, leading to ophthalmoplegia .
