Can PCOS cause sudden weight gain?Hormonal Conditions PCOS
I’m a 21 yo female. I’ve been having irregular periods since I was 15 years old. For the past 5 years, I used to have a stable weight at around 50kg. However, in the past 2 months, I’ve gained about 5kg. Can PCOS cause sudden weight gain, and how will I know if my sudden weight gain is due to PCOS? Thank you!
PCOS is a condition that is associated with weight gain and obesity, and women with PCOS find it easy to put on weight and difficult to lose weight. Most women with PCOS gain weight over a period of months and years.
Such a rapid weight gain of 10% body weight in 2 months is not typical of PCOS, though if other causes have been excluded, may well be the case.
It is important to exclude other causes, for example hypothyroidism (low thyroid hormones) and hypercortisolism (high steroid hormones) as they're also associated with weight gain and irregular menstrual periods.
I would suggest seeing an endocrinologist who can help investigate for the underlying cause of your weight gain and manage accordingly.
