Get the details on rhabdomyolysis.


Weakness is a medical symptom that can be brought on by various underlying conditions. One of these possibilities is rhabdomyolysis. Some of the other things that can lead to it are mentioned on this page. Keep in mind that the term weakness can refer to a variety of things, such as exhaustion, missing muscle strength, malaise, etc.


In this situation, the patient has a low level of potassium in the blood. In many cases involving a mild level of hypokalemia, no symptoms are noticed. There may be a slight increase in the patient's blood pressure. In some cases, cardiac arrhythmia can occur. When the decrease in potassium becomes moderate, then additional symptoms can present, one of which is weakness of the muscles. The muscles can also be affected with pain and cramping. Severe cases can lead to even further symptoms. Additionally, in a severe case of hypokalemia, it is possible for the situation to lead to rhabdomyolysis.

Hypokalemia itself can be caused by different situations. It is possible for a diet too low in potassium to lead to this, although that rarely occurs unless there is a significant loss of this mineral from the person's body. More frequently, the situation occurs when this loss takes place, in many instances related to significant loss of fluid. Diarrhea is one example of this. For information about diagnosis of hypokalemia and how to treat a particular case, talk with a doctor or other professional.

Vitamin D deficiency

Some amount of this vitamin can be ingested in the diet, but it is often received by exposure to sunlight. Therefore, the combination of a diet low in it along with insufficient exposure to sunlight may lead to this deficiency. Other situations can also cause it, such as things that lead to poor absorption.

As far as symptoms go, weakness of the muscles can occur. Muscles can also be impacted by twitches, as well as aches. The bones in particular can also be affected by this condition. One example of this is that osteoporosis can develop. In osteoporosis, bone density is lowered. Osteomalacia, a softening of the person's bones, can also result. Another possibility is that the person may have rickets, another situation in which the bones are softened. Osteomalacia occurs in adults, whereas rickets impacts children.
