I'm have symptoms related to IBS, hyperthyroidism, and blood sugar issues...can these all be related?After I eat, my vision becomes blurry and I have heart palpitations. I often have to go to the restroom about 10 min. after, but not always. I also experience frequent nausea after eating. I have already had my gallbladder removed (due to nausea, stomach pain, and frequent diarrhea) and had a hysterectomy (due to irregular periods) and am still experiencing hormone issues and digestive problems. Could a thyroid disorder be the root of my hormon and digestive problems?
