Why Did I Gain 10 Pounds in a Week?
While some weight fluctuation is normal, a fluctuation of 10 pounds is a little excessive. Overnight weight gain can be the result of water retention, changes in metabolism, and the timing of meals. People weigh different amounts at different times of the day, too.

What can cause you to gain 10 pounds in a week?

When weight gain is not related to a health condition, common causes include:

  • eating more.
  • menstrual cycle.
  • perimenopause and menopause.
  • metabolism slowing down with age.
  • being less physically active.
  • water retention due to dehydration or excess salt.
  • stress, depression, or anxiety.
  • lack of sleep.

Why am I gaining weight so fast all of a sudden?

It's often due to fluid retention, abnormal growths, constipation, or pregnancy. Unintentional weight gain can be periodic, continuous, or rapid. Periodic unintentional weight gain includes regular fluctuations in weight. One example of unintentional weight gain is experienced during a woman's menstrual cycle.
