putting it back on?!?!

I am almost 7 years post op. I had the full bypass done. I had done very well, lost 100lb, maintained that for about a year then my body got comfortable with between 75-85 loss. I maintained this for about 5 years, until recently.
As of the begining of the year I have gained 17 lbs. I have also started doing Zumba at least two times a week,either walking on a treadmill during lunch or taking walks, about twice a week. Loaded an ap on my phone to help me record what I was eating. Not that I was eating bad before, but with a log you are more concious. Since doing all of this, I have put the weight on.
Getting frustrated, went to my doc and had blood work, as we were concerned that it might be my thyroid, with other symptoms I have. Thats not it, according to blood work. Has this happened to anyone else? am I just losing my mind wondering what I am doing wrong?
Is it possible that due to my surgery my levels would be different and my thyroid could really be worse than it shows?
soooo frustrated right now.
thoughts/suggestions....
thanks,

How many calories per day are you eating?

What is the proportion of macronutrients (aka Fat/Carbs/Protein)?

my response to a poster below: why some people gain weight

Some of us get severe RH 1-2 years post op RNY. And eating become an issue. Real issue. If I do not eat enough or often enough - my BS will drop, if I eat too many carbs - my sugar will drop, if i eat only proteins - my sugar will drop... and so on...
The very fine line where I have to eat enough to make sure my BS is stable and not too much to gain weight. And the "fun" is every day. And exercise - yea --- that is tricky also - any serious exercise - and my BS drops.
Reactive hypoglycemia and Hypoglycemia. There are no "save" carbs for me (except fiber), there are no "good carbs' and "bad carbs". Some are worse than others. Some will always make my BS drop some - some times only and with combination of other things, an only if I eat too many of them.
Post op RNY... regain due to insulin overload.. how fun...

Now most people do not have as severe RH. Some have - but just do not know it - they get the shakes - they eat, eat - graze carbs all day - because they get hungry... very hungry...
When your BS drops below "save level" - first you get hungry.... (my BS will be app 60?) I still can wait... and try to ignore that..but at 55-60 the normal survival instinct kicks in and you have to eat. But if that drops to 40'3 or 30's or even below... that's when the real "fun" begin... (horrible panic like attack, possible seizures, blackouts, etc...)

I do try to follow a very well balanced - low carb, high fiber, high protein moderate fat diet. Every meal has to be balanced. I am on a "very strict permanent diet" for the rest of my life...


New Data on Weight Gain Following Bariatric Surgery

Gastric bypass surgery has long been considered the gold standard for weight loss. However, recent studies have revealed that this particular operation can lead to potential weight gain years later. Lenox Hill Hospital’s Chief of Bariatric Surgery, Mitchell Roslin, MD, was the principal investigator of the Restore Trial – a national ten center study investigating whether an endoscopic suturing procedure to reduce the size of the opening between the gastric pouch of the bypass and the intestine could be used to control weight gain in patients following gastric bypass surgery. The concept for the trial originated when Dr. Roslin noticed a pattern of weight gain with a significant number of his patients, years following gastric bypass surgery. While many patients could still eat less than before the surgery and become full faster, they would rapidly become hungry and feel light headed, especially after consuming simple carbohydrates, which stimulate insulin production.

The results of the Restore Trial, which were published in January 2011, did not confirm the original hypothesis – there was no statistical advantage for those treated with suturing. However, they revealed something even more important. The data gathered during the trial and the subsequent glucose tolerance testing verified that patients who underwent gastric bypass surgery and regained weight were highly likely to have reactive hypoglycemia, a condition in which blood glucose drops below the normal level, one to two hours after ingesting a meal high in carbs. Dr. Roslin and his colleagues theorized that the rapid rise in blood sugar – followed by a swift exaggerated plunge – was caused by the absence of the pyloric valve, a heavy ring of muscle that regulates the rate at which food is released from the stomach into the small intestine. The removal of the pyloric valve during gastric bypass surgery causes changes in glucose regulation that lead to inter-meal hunger, impulse-snacking, and consequent weight regain.

Dr. Roslin and his team decided to investigate whether two other bariatric procedures that preserve the pyloric valve – sleeve gastrectomy and duodenal switch – would lead to better glucose regulation, thus suppressing weight regain. The preliminary data of this current study shows that all three operations initially reduce fasting insulin and glucose. However, when sugar and simple carbs are consumed, gastric bypass patients have a 20-fold increase in insulin production at six months, compared to a 4-fold increase in patients who have undergone either a sleeve gastrectomy or a duodenal switch procedure. The dramatic rise in insulin in gastric bypass patients causes a rapid drop in glucose, promoting hunger and leading to increased food consumption.

“Based on these results, I believe that bariatric procedures that preserve the pyloric valve lead to better physiologic glucose regulation and ultimately more successful long-term maintenance of weight-loss," said Dr. Roslin.

Are your clothes getting tight also or are you just looking at the number on the scale? You might be putting on muscle..In which case you're doing all you can.

The clothes are definatly getting tighter. I (along with many people) thought it was the muscle thing. but with the tightness in the clothes, I am not thinking that is what it is.

I am also 7 years out and am having these yearly patterns.... in the spring I go up 12-15lbs and in the fall/winter I go back down. I am not aware of what it is that I am doing but its something. My bloodwork has always come back normal. I have had no issues with absorption and am stumped and getting no help from the dr who at this point thinks that I am crazy! So, in the event that I am grazing and not realizing it, I recommend that you keep a food and exercise diary.
