• Hormonal changes: The levels of estrogen and progesterone, which are female hormones, fluctuate throughout the menstrual cycle. It is thought that these changes may affect the levels of other hormones and chemicals in the brain, leading to the physical and emotional symptoms of PMS.
• Genetics: Some women may be more susceptible to PMS due to their genes.
• Nutrition: A diet that is low in certain nutrients, such as calcium and vitamin D, may increase the risk of PMS.
• Stress: Elevated levels of stress can make PMS symptoms worse.
