What Causes Diabetes Along With High Blood Pressure?

Hello. Yes I have a huge question. I am a 50 year old,young lady. I have multiple illnesses. I am diabetic, I have high blood pressure, high cholesterol that s good now with medication. I have arthritis, fibromialgia, bone density, gerd and gastroporiesis. I am on all sorts of meds. My question is, I was diagnosed with gastroporiesis last year, I ve always had trouble moving my bowels, it can take over a week for me to go and that s because I get so much pain, I end up taking all the meds my Dr has prescribed, like lactose, miralax, metamucil, linzess, amitiza and stool softeners and it still takes forever. I ve had testings done like an endonoscopy and colonoscopy.. I don t know what else to do, help.?
