My son had a roux en y (which may have been a roux en o- which means an "error") 10 years ago. He was diagnosed with a copper deficiency 2 years ago. Not a single dr that he has seen had a clue as to what it is. It is not rare! It is misdiagnosed as MS, Lupus, etc. He has much neurological issues. He has malabsorption and this has resulted in mild brain damage, digestive issues, severe pain everywhere, spinal problems... and can cause osteoporosis and much more. He researched his symptoms a year or so before he saw a Dr.. No insurance. When he finally had to leave his job and had a couple of trips to the ER, he was granted financial aid from the local hospital. He had realized that he had a copper deficiency and on his first visit to the primary care physician, he asked the dr to please check his copper and zinc levels. The dr rared back in his chair and treated him like an idiot. At his 4th visit, he finally consented ito check his levels. The copper lab took almost a week to come back. By that time my son was deathly sick and transported by ambulance to the hospital. That very day, his results were in and his copper level was bottomed out. Even in the hospital, no one knew anything. Bariatrics surgery is a living, breathing nightmare, with symptoms showing up 10 or 20 years down the road. His surgery was an emergency due to a duodenal ulcer, but he was never told that he should have certain vitamins and minerals checked every year (copper and zinc every 6 months) for the rest of his life. I know this is probably too much info.. I am just so frustrated. There is a Dr. Heeraj Kumar at the Mayo Clinic in Minnesota that really knows his stuff. If you can read some of his articles, it may help you. Praying for you and her!
