Dr abd home scales so different?

Is your home scale on tile, wood flooring, carpet? Is the floor fully level and flat? Are the feet of the scale dirty? Did you set it to zero when you weighed yourself?

My scale can read my weight up to 100lbs less if it's placed on carpet. If I put it on one part of my floor that is not fully level it can read up to 50lbs plus or minus my actual weight. Placed on tile it can read up to 30lbs less if it's placed between a few tiles. When the feet of my scale are dusty, dirty, etc it can read much lower or much higher.

I believe electronic scales can be wrong due to the amount it is used, if it's kicked, moved, etc. Also, you would of weighed more at the doctors due to wearing shoes (if you were), what you have drank, eaten and the clothing you were wearing... however that most likely wouldn't cause a 40lb difference.

My scale is on flat viyanl flooring. I had eated and drank before dr appt.

You shouldn't be getting drunk before Doctors appointments.

If they smell it on your breath they'll make a little note saying that your an alcoholic and they'll try to persuade you to go to meetings. They'll also be more conservative when prescribing pain killers.

Do you have a harder floor to try your scale on? Tile or hardwood?

I find vinyl isn't the greatest as it may of been placed on uneven flooring and vinyl doesn't fix that problem all the time. I find vinyl can have higher/lower spots especially in somewhere like a bathroom where there may be some moisture underneath.
