what is pms

Premenstrual syndrome (PMS) is a combination of physical and emotional symptoms that many women experience after ovulation and before the start of their menstrual period. Symptoms tend to recur in a predictable pattern, and they can range from mild to severe. Some common symptoms of PMS include mood swings, tender breasts, food cravings, fatigue, irritability, depression, bloating, headaches, and trouble falling asleep. Emotional and behavioral symptoms such as tension, anxiety, crying spells, mood swings, and irritability or anger are also common. PMS is estimated to affect up to 75% of menstruating women, and it is most common in women in their 30s. While the exact cause of PMS is unknown, researchers believe that changes in hormone levels during the menstrual cycle may play a role. Treatments and lifestyle adjustments can help reduce or manage the signs and symptoms of PMS.
