Muscle Weakness in Legs

Our legs are the supporting pillars of our body. They not only help in locomotion, but also support the entire weight of the body. Like the rest of the body parts, the legs are also richly supplied with blood vessels and muscles, which give the leg its shape. These muscles help in the movement of the legs and also provide anchorage to the bones. There are times when we may experience muscle cramps or muscle weakness in legs. In some cases, the individual may experience so much weakness that he is unable to stand for a long time. This condition is seen in adults as well as in children.

Causes of Weak Muscles in Legs

Muscle weakness in legs may be caused due to a number of factors, some of which may be minor, whereas some may require immediate medical intervention. Muscle weakness can also be noticed in other parts of the body.

• One of the most common reasons why most people complain of muscle weakness is because of an improper diet. Owing to the fast lifestyle, many people opt for fast food rather than healthy food. Though junk food appeases hunger, it does not satisfy the nutrient requirement of the body. Hence all this may end up in not just weakness in the legs, but the entire body.
• Another leading cause for weak leg muscles is because of poor circulation in legs. Improper blood circulation to the legs can be caused due to blocked arteries and also because of broken capillaries on legs. This can deprive the legs of the mush needed nutrients, thereby weakening the muscles.
• Involuntary muscle twitching in legs, accompanied by a feeling of weakness may be due to overexertion of the leg muscles. Prolonged use of muscles without sufficient rest can make them become weak and sore, and a condition called muscle fatigue may set in.
• A hormonal disorder, called Addison's disease, as a result of under production of aldosterone and cortisone (hormones of the adrenal gland), is also one of the causative factors for weak muscles in the legs.
• Autoimmune disorders like Grave's disease can weaken the muscles in the legs. Caused due to an overactive thyroid gland, this condition can also exhibit muscle twitching in the extremities as one of its symptoms.
• Another autoimmune disorder which causes the muscles of the legs to become weak and lethargic is Gullain-Barre syndrome. This disorder is caused because the immune system attacks the healthy nerves. Other symptoms of this condition include a feeling of numbness and tingling sensation. If not diagnosed on time, it can result in paralysis.
• Myositis, a condition which is caused due to inflammation of the muscle fibers is also one of the causes of muscle weakness in the egs. This weakness can radiate towards other parts of the body, making the person feel fatigued and also experience body pain.
• Other reasons for noticing muscle spasms and twitches, followed by weakness in the legs are multiple myeloma, hemiplegic migraines, multiple sclerosis, restless legs syndrome etc.

Providing Relief from Muscle Weakness

Though experiencing muscle weakness in legs may not always be a cause of grave concern, it is advisable not to put it off as 'something usual'. Better get to the root cause of it now rather than regretting about it later. Consult a doctor if you experience persistent weakness followed by muscle pain, so that exact diagnosis and treatment can be provided. Eating foods rich in vitamins and minerals will strengthen the weak muscles. Leg exercises can improve circulation of blood in the legs and prevent the muscles from becoming weak. Ample rest for short intervals will also keep this condition at bay.

Take proper precautions to prevent the onset of this condition. A proper diet, regular exercise regimen and visiting a health care provider for a routine body analysis will prevent the occurrence of any disorder. Stay healthy!
