Chia seeds are a diet pill that should not be taken during menstruation in general. During menstruation, women may experience a loss of appetite due to a decrease in hormone levels, and this may also lead to fatigue and weakness. Chia seeds contain more dietary fiber and women may feel full after taking them, which can aggravate the loss of appetite during menstruation and also lead to diarrhea, which can lead to weakness and be detrimental to health. If women need to take chia seeds to lose weight, it is best to take them after the menstrual period and after the body has recovered, the effect will be better. During the period, you should pay attention to proper rest and eat light, nutritious food to minimize the lack of nutrition due to the loss of menstrual blood.
