Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. You need to take Amygra life long as there is no specific cure for this problem which is myasthenia gravis. You can try taking Ashwagandha (after consulting a herbalist) .This herb is effective in such auto immune conditions. High potassium foods should be tried bananas , apricots etc. Avoid trans fats like animal fats . Do not consume more sugary foods as they increase inflammation. Eat smaller meals. Vitamin D and calcium should be taken after advice from your doctor. Hope I have answered your query. Let me know if I can assist you further.
