Hi, from past few months i have been noticing a lot of weakness in my body. i also feel shakiness in my hands and suffer from cramps in legs and feet.

See a physician: You should consult a physician. Who can examine you and run some lab test to rule out other causes of weakness and tremors like anemia hyperthyroidism and medications.I guess that you may be suffering from dehydration, hypokalemia or hypoglycemia which is causing your symptoms. In the meantime you cut back on all caffeine nicotine and alcohol intake. See your internist for work up asap.

Many possibilities: Low blood pressure, low blood sugar, and magnesium deficiency all cause those symptoms. Stay well hydrated, eat 6 times a day healthy unprocessed foods with fresh raw vegetables and fruit and high quality protein and good fats. Take sufficient vit d3, check body temperature if low take more, and vit k2, get a good night sleep, move through the day, and manage stress well. See kelly mcgonigal.
