What causes your nails to break during your periods?

Nail brittleness during periods can be attributed to hormonal fluctuations that affect the body's hydration and nutrient absorption. Changes in estrogen and progesterone levels can lead to decreased moisture and weakened keratin, the protein that makes up nails. Additionally, menstrual symptoms like bloating and cramping may lead to dietary changes or reduced nutrient intake, further impacting nail health. Stress and fatigue associated with menstruation can also contribute to nail breakage.
