Women's Menstrual Cycles Can Affect Blood Sugar

Hormonal changes during a woman's premenstrual phase such as cramping, bloating, and mood swings, might cause the blood sugars to significantly vary.

Depending on the person, some diabetic women may become less sensitive to insulin in a week or two prior to their period, which can result in higher-than-normal blood sugar levels. Right after menstruation begins, readings usually return to normal. Reduce your intake of carbs at that time or add more exercise if you notice that your blood sugar levels are regularly high the week before your period.
