Hello, my daughter, 45 years old, has had IBS for the last several years. She gained a lot of weight, her maximum being around 210 pounds, which gave her a lot of pain in her hips and knees. Trying to get rid of so much pain, she opted to have a Bariactric surgery in Toronto, on March 3rd, 2015. Since then she has lost about 55 pounds, but she has also had constant diarrhea, which has sent her to the emergency department numerous times. due to her potassium level being very low, her dizziness, and her extreme weakness. I am extremely concerned about my daughter, she seems to be weaker by the day. Can you help???
