Hello, what you said is true. Women who lose weight, whether they take diet pills or not, will lead to a decrease in menstrual flow.

Guiding opinions:

In fact, the reason is very simple. Taking medicine to lose weight is because there are hormones in the medicine, and dieting exercise is because of insufficient nutrition in food intake. I wish you good health.

The above is a suggestion on the problem that "during the weight loss period, the amount of menstruation becomes very small, and almost no on the third day". I hope it helps you, and I wish you health!
