Premenstrual syndrome (PMS) involves a range of physical and emotional symptoms that occur during the latter half of a woman's menstrual cycle, typically resolving with the start of menstruation. Physically, PMS can cause symptoms such as breast tenderness and bloating, while emotionally, it may lead to feelings of anger and depression. These symptoms are believed to be linked to monthly hormonal changes, involving sex hormones, neurotransmitters, and peptides. It's important to differentiate PMS from other conditions with similar symptoms. Keeping a menstrual diary is a valuable method for diagnosing PMS. Treatment options include regular exercise, dietary adjustments, support from loved ones, and medications. These medications may consist of diuretics, pain relievers, oral contraceptives, and drugs that inhibit ovarian function. PMS is the common abbreviation for this condition.
