My daughter (mentioned above) is 16 and we have found tremendous information and support on the facebook page for SMAS. They offer valuable advice based on their own situations (not medical advice) and a great list of documents and links. It's been fabulous since we're new to this as well! I have heard privately from one survivor that "reversed" the SMAS after gaining weight. Her biggest piece of advice was to see a nutritionist that specializes in eating disorders and a nutrition therapist, but those that are willing to learn about SMAS. To answer your questions---Yes, our daughter was advised to gain 10 lbs in the next 3 months or the next step would be feeding tube (maybe). And fortunately for R, she has not had a problem with vomiting at all. She has all of the other symptoms, but not that. Her SMAS was also diagnosed after a barium swallow test. Hope this is helpful! But be sure to check out the FB page--it's a gold mine of info. Let me know if you have any other questions. This is definitely a battle.

My 40 year old husband was diagnosed with SMA on October 12, 2012. He is 6 foot tall and was down to 122 pounds before any of the doctors could figure out what was wrong. He had a g/j feeding tube placed on August 31, 2012 because he was losing weight so rapidly. We had already been diagnosed with Pancreatitis, Cyclic Vomiting, Stress, Delayed Gastric Emptying, and Chronic diarrhea. He was diagnosed after an Endoscopic Ultrasound. We have refused the repair surgery because of the high mortality rate we found. He is 100% feeding tube dependent and up 10 pounds from the date we learned what he had. We have gone to a high protein, high calorie formula and we are doing automatic flushing with his feeding pump so he is getting 100% of his calorie and free water intake daily. He is just starting to regain the ability to eat without throwing up everything. His doctors (in Kansas City) are very optimistic that with continued weight gain that he will be symptom free. They have urged him to gain about 80 pounds. They would like to see him weigh around 200 pounds for the rest of his life. He will also need to keep the feeding tube so that if he were to get sick with anything (like the stomach flu or a cold) and he were to not feel good, we could tube feed him to keep him gaining or maintaining weight.I have looked on Facebook for a support group and the only things I can find are a few sights run by young women that talk about their day to day life. I wish them the best, but that isn't really what my 40 year old husband is looking for. He would like information about what to expect as life goes on with all the complications of SMA Syndrome. We have 5 children and wonder if we should have our tall, thin children checked for the defect on the SMA to prevent them from ever getting sick.
I am glad to finally find a site that actually has other folks that recognize this syndrome.
