I have noted that hypoglycemia can cause muscle twitching. It can also caused slurred speech and behaviour changes. I can see how maybe someone who is hypoglycemic and slurring could be concerned especially if they are twitching. That being said if a person eats the symptoms should dissapear unless there is some kind of endocrine malfunction or perhaps a problem with the process in the manner the muscles are metabolizing glucose. Has anyone here been diagnosed as hypoglycemic or does anyone have more in depth information on potential problems with the way the muscles are using glucose?Edit: The more I look into this the more complex it becomes especially when it comes to muscular uptake of glucose. In fact a certain autoimmune response may prevent proper uptake of glucose in the muscles. The synthesis of glucose in the muscles is far more complex than what I learned in high school biology. It involves sodium, magnesium and the kidneys, but also involves something called cytokine which is a soluble protien which binds to receptors."In recent years, the cytokine receptors have come to demand the attention of more investigators than cytokines themselves, partly because of their remarkable characteristics, and partly because a deficiency of cytokine receptors has now been directly linked to certain debilitating immunodeficiency states"These receptors can be affected by toxins including tobacco and alcohol.
