After about 35 minutes of riding my road bike, both of my hands get numb. I have drop bars that I grasp at the top, just behind the brake levers, and wear padded cycling gloves. The bike seems to fit me well enough. Is there some ergonomic adjustment that I should consider, such as raising the bars or moving the seat fore or aft?
Level top of bars with the seat
and not too far a reach,
I'd think about a shorter extension stem , though it may be higher in height.
Saddle setback from the perspective of the BB axis
should put more body weight on the back, and off your hands ..
and change hand position , including riding with one hand
to let the compressed tissues restore themselves a bit.
Try to vay your hand position frequently, and keep the pressure off the "valley" at the heel of your hand. That's where the nerves and blood vessels run, snd keeping pressure on that = numbness.
Do whatever it takes to get your body weight off of your hand/wrist or you may cause permanent nerve damage!!!

I've had surgery last year which helped at lot and I now cycle with TWO (2) pair of Specialized BG Gel gloves, UPC 6709-0193 (L over M). The Gel gloves do a better job than most styles in filling the valley in the center of the rear of your hand -- where the medial nerve runs -- and padding the outside of the rear of your hand -- where the ulnar nerve runs.

don't put so much pressure on your hands. pick them up from time to time while you ride, shake them around. your weight should be mainly on your butt on your saddle (and stand up every once in a while) and your hands should rest gently on the bars, enough to guide them, but not to support you.
