Gastric bypass 6 months ago. Is 2500 mcg b12/daily too much? Will my kidneys jus flush out the excess essentially wasting it?

Yes, you are wasting: Daily requirement of B12 is less than 3 microg, even with gastric by gastric bypass you produce intrinsic and can absorb it in the distal ileum, any excess beyond liver storage capacity will be eliminated by the body. Vegans also need supplementation. Speak to your doctor, if you want your B12 levels could be checked. Read more

On a CAT scan for kidney stones fecalization of distal ileum possibly early obstruction was picked up. I am 61. two years post gastric bypass with two?

On a CAT scan for kidney stones fecalization of distal ileum possibly early obstruction was picked up. I am 61. two years post gastric bypass with two?

Tough to answer: Hi
I wasn't able to see the remainder of your question due to the character limit, but small bowel obstructions are usually diagnosed with clinical findings in combination with radiographic findings. Just hearing about your CAT scan findings isn't enough to say whether or not you could have "early obstruction". Would be happy to discuss further via inbox consult if you wish. Hope this helps.

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's, (5'4", 203), but isn't there a less invasive answer?

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's, (5'4", 203), but isn't there a less invasive answer?

Options: Probably theist popular weight loss operation at the moment is a sleeve gastrectomy. Its not really less invasive, but has less potential for long term side effects. There are also some newer endoscopic therapies, but they are not so effective. Ask your doctor if a consultation with a Bariatric surgeon is appropriate. Hope this helps! Read more

How can I tell if I have stretched out my gastric bypass pouch, are there any symptoms?

How can I tell if I have stretched out my gastric bypass pouch, are there any symptoms?

Try Bagel Test: After a bypass, you can test your pouch size and emptying by a bagel test. Eat mini bagels until full (in morning without any fluids). Record number of bagels (could be up to two for normal). Then wait 30 minutes. Don't drink anything. Try eating mini bagels again. Ideally, most of the pouch should still be full and you should only be able to eat one. Read more

For what reason wouldn't gastric bypass work on some people?

For what reason wouldn't gastric bypass work on some people?

Gastric bypass fail: In order for a gastric bypass to work, the patient must do their part which is to eat healthy food, eat the right portions, and exercise. The operation helps with eating the right portions, but it doesn't dictate what you eat. You can eat junk food, not exercise, and defeat a gastric bypass. Also, overeating can stretch the pouch and make it easier to eat more food. Read more
