Had gastric bypass. i stay extremely thirsty but my blood sugar stays around 100. anything i can do?

Thirsty after surgry: The normal blood sugar rules out diabetes or similar problems. The first treatment is just to drink more fluids. The thing to be watching out for are sources of increased fluid losses--e.g., excessive urination, diarrhea, excessive sweating, or fever. If you are still in the early post-operative period, your gut may still be hiding some fluid losses from your system inside.

Could be meds: A dry mouth could be due to medications you are taking. As you lose weight, some medication doses need to be reduced, since their effect is now greater with less weight.

Thirst mechanism: Thirst mechanism is tightly regulated by the hypothalamus/pituitary gland in the brain through receptors called osmoreceptors. These receptors are very sensitive to sodium concentration in the blood and if you have a defect in this axis, such as no release of avp hormone, you can lose water through kidneys and as such have constant thirst. This is one possibility of why you have constant thirst.

No Room: My understanding is that this is a temporary problem which many people experience following such an operation. Suddenly you can't just drink a whole glass of water at once. You don't have enough room anymore. It gets better. Some patients recommend sucking on ice or popsicles. Having something that wet and cold in your mouth may be satisfying. Don't gulp down fluids! hang in there!
