General or Other | Rheumatology | Weakness in Generalized Muscle (Symptom)
The muscle weakness or inability represents the difficulty to perform an act for the engine by lowering the mechanical energy of the muscle. It can occur typical muscle fatigue; in organophosphorus poisoning; paralysis or paresis. Muscle fatigue and muscle weakness are two terms often used interchangeably, but actually describe two completely different sensations. Muscle fatigue can be generalized or can affect only a muscle or muscle group.
Some diseases of the neuromuscular system, trauma, metabolic diseases and toxins-all these are causes of significant muscle weakness. Muscle weakness is a feeling of muscle strength or physical sensation that it takes extra effort for regular daily activities that need to move the arms, legs or other muscles. Muscle fatigue is a feeling of tiredness, exhaustion, lack of energy. Both muscle weakness and fatigue are symptoms, not diseases. Because they can be caused by a variety of diseases, the importance of weakness and fatigue can only be determined when other symptoms are evaluated.
When fatigue occurs along with more severe symptoms such as dyspnea (difficulty breathing), abnormal bleeding or unexplained weight loss or gain, it is needed a medical specialist. Fatigue that lasts longer than 2 weeks usually requires specialized medical investigations. This type of fatigue can be caused by a more serious medical problems such as:
(i) Anemia - decreased amount of hemoglobin, which is the carrier of oxygen;
(ii) Heart disease ;
(iii) Thyroid - hypo and hyperthyroidism;
(iv) Kidney or liver disease - cause fatigue when the concentration of certain substances reach toxic levels;
(v) Sleep disorder - insomnia, obstructive sleep apnea, narcolepsy;
(vi) Allergies - hay fever, asthma;
(vii) Infections that require a long convalescence - bacterial endocarditis (infection of heart muscle or heart valves), parasites, HIV, tuberculosis and mononucleosis.
