I am 5 years post op RNY and I already had to have iron infusions 2 times.  Most of the time - the prescription iron are not that good ... and if she takes them and her number are low- then why does she take them (that iron causes severe cramps and constipation in me) 

some of the shots are only good as calories - and then even not so much. They are not good as protein supplements... wrong type of protein - unless all is from whey isolate... (they have some shots from whey) 

It is made from soy. soy may affect thyroid in some individuals. Not everyone - but some may get long term becoming hypothyroid... hypothyroid= low energy, weight gains, being cold, etc, etc... 

some people may not be affected... 

click on the link and read that... 

I have one - few? in my pancreas.   The doc will probably follow up that. 

I am 5 years post op and in the last 5 years I have seen more docs than ever in my life.   

Some of those issues I had may be due to RNY  and losing weight (GB removal, hernia, etc) but some may bhave been there long term.  Just now - since I am not fat - the docs would listen and don't blame my issues on my weight (but some try to blame them on my RNY). 

Some people have no issues or minimal issue s- some have complications. 

Ulcers - I when I think I have an ulcer (or irritation ) I no longer see my doc for that - i start treating that right away... I have script for ulcer meds and I adjust my diet and usually all gets resolved in 2-3 months... (in 1 week most symptoms go away -as long as I follow easy diet... but like with any possible "wound" - the healing takes time). 

I deal with abdominal pain for last  year - but it only hurt when I eat "solid" - dense foods. So far I can drink proteins shakes, and get some liquid - or creamy soups. Also PB goes in just fine... but any meat, veggies, even thick yogurt - is no-no, unless I am willing to deal with pain.

Hope you find answers.  I and still looking for that,. 

Costco does not make me fat.   I shop there all the time.  Some food makes me sick, other - I chose not to eat ,,,  It is about choices.   Same food is everywhere else. 

Samples - I only pick some that are proteins.  And only AFTER I read what is in that. Otherwise - I don't bother.  Cheese, meats, even spreads (hold the cracker) ...and so on.  

Meat, fish, fresh veggies and fruits( only some of them) are my choices. They do have good selection and not too bad pricing. 

While losing weight I have to go to chiro over an over,, the body changes its shape and my back has been "twisting" 

Yoga helped a lot, so did acupuncture. 

You may also make sure that you get enough minerals, good oils and vitamins to support your joints. 

If after 2 moths you still feel tired - it may be time to do a detailed blood work. Sometimes surgery will mess up some of our minerals - vitamins levels and it may take a while before the body repairs itself.  

i.e. iron - ferritin - may drop due to surgery and since you are 3 years post op - this is the time some of us see ferritin drop. 

Also low B12 - and Vit D, also proteins amy make you leave tired and slow to heal. 

make sure you have DETAILED blood work done. Including iron, ferritin, B12, D, proteins, etc, to make sure all is were it needs to be. 

Don't relay on the doc telling you "all is fine" get your own copy and check the numbers. i.e. ferritin - the doc s call it normal when it is > 10 ... while some of us get really tired with ferritin below 50. Same with B12 - I feel my best with my B12 >800, and may feel tired when that is lower. 

Allergies. I know after RNY I developed some food allergies. unless I take allergy meds 2 x a day (or more) I can't speak. 

HUGS... I had disc issue , slipped and herniated, but not bone issue.  

If you are facing surgery - MAKE sure your adrenals are working right - make sure they check your hormones... in case you have adrenal deficiency - recovery from a surgery may be long unless you get extra help.
