Thursday, May 18, 2017

Muscle twitching is an involuntary contraction of the muscles fibres. In most common cases, it’s an outcome of muscle fatigue, but there are a few other causes to watch out for too that could be potentially dangerous for health. So let’s take a look at the top 3 things about Muscle Twitches.

  1. Common causes of muscle twitching

First, we are going to look into the common causes of muscle twitching. Minor twitching is usually less serious and results from lifestyle-related problems.

These are some of the common reasons for muscle twitching:

  • Rigorous physical activity could build up lactic acid in the muscles and can cause the muscle twitching. Intense exercise usually affects arms, back and legs.
  • Muscles twitching due to anxiety or stress could affect any part of your body.
  • Vitamin- and calcium-deficiencies could cause muscle spasms in the hand, calves and eyelids.
  • Individuals who are on an intense training regime and use caffeinated products to boost their performance in the gym could also experience muscle spasms.
  • Dehydration is a very common factor for shaky muscles.
  • Use of nicotine and tobacco can also cause twitching in any muscle of the body.
  • Certain drugs like estrogen and corticosteroids can also trigger muscle twitching.  
  1. More serious causes of muscle twitching

Muscle twitching could mean more than just a twitch in the eye. Some muscle spams could be a symptom of a more serious issue. Muscle spasms resulting from brain or spinal cord’s malfunction could damage the nerves that are connected to those tissues.

Following are a few rare, but serious causes of muscle spasms:

  • Lou Gehrig’s disease: Also known as amyotrophic lateral sclerosis, the Lou Gehrig’s disease results in the death of the nerve cells, so that twitching is an outcome of the dying cells.
  • Muscular dystrophies: These are a set of inherited diseases that can cause muscle spasms in the neck, hips or face.
  • Isaac’s syndrome: Frequent muscle twitching could occur in arms or legs from Isaac’s syndrome.
  • Spinal muscular atrophy: Any damage to the cells in the spinal cord could lead to a loss of control over muscle movement. However, spinal muscle atrophy usually causes twitching in the legs or arms first.

3. How to treat muscle twitching?

If you are training your body and if you don’t have any of the aforementioned diseases, muscle spasms are the symptoms of a quality workout, but not necessarily. If you are an athlete who on intense workouts and training, then muscle spasm are going to be a normality for you. However, there are ways you could reduce the frequency of their occurrence.

  • By eating a balanced diet that includes fresh fruits, veggies, quality carbs and moderate proteins, you could help your body against involuntary muscle spasms.
  • Manage your stress using different relaxations techniques like yoga or meditation. By exercising regularly, you could also reduce cortisol levels in the body that leads to stress.
  • Get sleep around six to eight hours every night. Optimal sleep helps your body recover and heal faster.
