Detailed Answer:
Hello,
Thanks for query.

Gastric bypass surgery refers to aprocedure in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch.So a large part of stomach is destroyed or is non functional. When alcohol enters the stomach of normal person, some of it is metabolized in the stomach by the enzyme alcohol dehydrogenase in a process known as first pass gastric alcohol metabolism.Now after by pass surgery the volume of alcohol dehydrogenase enzyme decreases significantly hence level of alcohol in blood increases very quickly.Secondly when volume of stomach is more it can keep alcohol stored for a long time(most of alcohol is metabolised in intestine) and is released into intestine much slowly as compared to a patient with very small stomach.
Hope i was helpful.

Hi, I m 28, female in Australia... I used to weigh 149kg s, I now weigh 89kg after having a gastric sleeve in dec 2011. My question is... What could be causing a irregular heart beat feeling and a flutter in my chest after I have eaten? I hadn t done any heavy exercise before eating so it s all at a slow regular pace. I used to get it before my weight loss surgery, but I m still having them. When it happens I check my pulse also it has a normal heart beat but then it feels like there is a slight pause and a hard thump right after. It happens quite a few times in the space of approximately 30seconds, then when I count my heart beat I count 50 beats in 30 seconds then after a minute I m fine again. This is really scary for me as i have heart problems in my family from my grandma (mothers side). What could be causing this?

I had gastric bypass surgery on June 11th. Last week I went back to work and 1 of he incisions strarted to bother me. It is red at the incision and the area surrounding it. The skin is also hot and it s painful. I called the dr and they said it was normal. I do not have a fever or stomach pain and the incision is closed so there is no puss or seepage of any kind. The nurse told me ice it and take Tylenol and eventually it would be ok. She said it was scar tissue healing and due to my increased activity it was very irratated. What do you think?

I had a stent put in after the gastric sleeve surgery. It has been 1.5 weeks and I am experiencing what I thought was reflux but it must be extreme GAS pain from the middle of my chest all through my abdomen . How long will this last? Is it normal? What can I take for it?? It is painful, especially at night and last for hours.
