Sometimes I have to weigh myself 3 times in a row cuz my digital scale is cold or just being weird. I weigh until I get the same number twice. Weighing every day can show you ups and downs tho. Its just how our bodies are.

I know the scales are best on a hard surface. We have a hard tile floor with large tiles in our bathroom, and I even try to keep the scales on one tile so it might be more consistent, being more likely level.

My husband is hypothyroid and has Congestive Heart Failure. His cardiologists tell him to weigh every morning after urinating and if his weight goes up more than 2 lbs in 24 hrs or 5 lbs in a week he needs to contact the clinic right away. I try for the same plan. There can be a connection between the thyroid and CHF; and water weight is a big issue for CHF.

I had the same problem until I invested in a new scale. I got the weight watchers scale. It is digital and very consistent. The other thing to remember is that our weight can fluctuate daily due to many differing factors. Water weight, sodium intake can be some of them. Weighing at the same exact time early in the morning the same day of the week with the right scale should give you more accurate numbers.

By mid day my weight is more than it was when I first got up. when I go to lb scal sometimes show that I have gained 5 lbs. I userly lose that temporary weight over night. na when I wake mid mormiing, n weigh in, will, scale doesn't indicate weight lose but when it's time for me to get up to start my day I have lost day before weight gain.
most of time it is due to temporary water gain, partical digest food,n/r the juice that body make while it is in process of digesting food, The later may not apply.
To set my scale to correct setting. I match it w Dr offc scale. mine appears/is set 3 lbs. more than if it was set on 0. it is pre set on 0 when I step on it. that gives me correct weight.
I used a magic maker, n out lined my scale on certain spot in my kitchen. I can set the scale slightly outside the drawing, the scale indicate more than it always does when the scale sets completely inside box area.
Occass inal I check my home scale with Dr offc scale.

Good night/day for now!

I weigh only once a week, but like Jen if my number seems weird I might go a couple times in a row till I get the same number twice and go with the double number.

I weigh every Friday morning after I pee and before I eat anything, just barely bday suit level lol. If I exercise that day I might weigh again after I exercise before my shower (as I exercise in the morning before I eat or drink anything).

My scale is a Biggest Loser Scale (goes up to 400lb and my highest was 330) from Walmart. I think I got it for $20 or something. It's pretty accurate and have had no issues with it.

I don't know if any of that helps at all since I haven't had your problem, but I hope you can get it sorted out soon cause I can't imagine how frustrated you must be. Good luck!

The misery we have to put ourselves thru......LOL
