If you take blood-thinning medicines regularly, talk with your doctor about how to manage your medicine. Do not take sucralfate (Carafate) or antacids on the day of the test. These medicines can make it hard for your doctor to see your upper GI tract.Before the test, you will put on a hospital gown.If you are wearing dentures, jewelry, contact lenses, or glasses, remove them.For your own comfort, empty your bladder before the test.f you take blood-thinning medicines regularly, talk with your doctor about how to manage your medicine.

A cylinder has 2 flat surfaces and 1 curved surface. In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines.As such it can have any number of flat surfaces but need not have any at all.A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively; these have no flat surfaces.s such it can have any number of flat surfaces but need not have any at all. A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively; these have no flat surfaces.
A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively. An elliptic cylinder with the half-axes a and b for the surface ellipse and the height h.An elliptic cylinder is a quadric surface, with the following equation in Cartesian coordinates : This equation is for an elliptic cylinder, a generalization of the ordinary, circular cylinder (a = b).here d is the diameter. For a given volume, the closed cylinder with the smallest surface area has h = 2r. Equivalently, for a given surface area, the closed cylinder with the largest volume has h = 2r, i.e. the cylinder fits snugly in a cube (height = diameter).
