 [ Symptoms ] i have been diagnosed with pcos ibs insulin resistance hypothroidism and a vitamin d deficiency what should i do  i was diagnosed with pcos about a year ago i found out today about the rest of them i am unsure how these all relate to each other and what i should do next [ Disease ] the first thing you should do is work closely with your healthcare provider he or she should be able to recommend vitamin d supplementation to get your levels back up there is definitely a connection between pcos and insulin resistance and possibly ibs i recommend you see a registered dietitian as all of these health conditions are related to nutrition and weight a dietitian can help you develop a meal plan to help improve pcos and insulin resistance and pinpoint foods that increase your ibs symptoms all while taking your lifestyle and personal preferences into consideration to find a dietitian near you go to eatright org good luck
