In injection technique, a higher gauge corresponds to which change in the needle?

A higher gauge means the needle has a smaller bore, so it’s thinner. Gauge measures the diameter of the needle lumen, and as the number goes up, the diameter shrinks. Length and thickness aren’t the same thing—you can have long or short needles in a range of gauges, but the gauge specifically tells you how thick the needle is. In practice, choosing a higher gauge (thinner needle) can reduce discomfort and tissue trauma, though it may be harder to use with very viscous solutions or risk bending.
