Your cycle and the scale
Why many women see higher readings before a period, and how to keep your trend fair.

Many women notice that their weight rises for a few days before their period and falls again afterwards. This is common and usually water, not fat.
Why it happens
Hormone changes across the menstrual cycle affect how much water the body holds. Bloating, cravings and changes in sleep can add to it. The pattern differs from person to person and month to month.
Keeping your trend fair
- Compare like with like. If you want to compare months, compare the same point in your cycle.
- Look at the trend. One higher week does not change a steady line much.
- Tag it. Tap Period when you add a weigh-in. Evenly will learn your pattern and explain higher days.
If you are trying to lose weight
A higher week before your period can feel discouraging. Knowing it is expected helps. Watch the trend over two or three months.
When to see a doctor
See a doctor if your periods change a lot, are very painful, or if you notice large or rapid weight changes you cannot explain.
