Diagnosed with small hiatal hernia. no gerd at all. what are the chances it grows and gives me gerd in future. 23yo 145lbs. it hapnd frm hevy lifting ?

Yes It can develop.: Heavy lifting doesn't always have too much to do with hiatal hernia as opposed to a groin hernia. A small hiatal hernia can certainly get bigger. The GERD or the reflux can be prevented or minimized by paying attention to your lifestyle in avoiding the late or the large meals and also in using an extra pillow when needed. Watch your weight.
