Common symptoms of premenstrual syndrome include bloating and weight gain, headaches, mood changes and food cravings, states the Office on Women's Health. Other symptoms include swollen or tender breasts, acne, constipation or trouble with memory or concentration.
In addition to these symptoms of PMS, WebMD also lists fatigue, irritability, low sex drive, sadness and anxiety as other possible symptoms of PMS.
According to the OWH, premenstrual syndrome is a series of symptoms that commonly occur one to two weeks before a woman's menstrual period. Most women experience relatively mild PMS symptoms, although about 3 to 8 percent of women suffer from premenstrual dysphoric disorder, or PMDD. Symptoms of PMDD include more severe instances of depression, such as sadness or hopelessness, anxiety or tension, extreme moodiness, or marked anger or irritability, states Mayo Clinic.
Although not fully proven, the OWH attributes the causes of PMS to hormonal changes within the female body. However, other PMS symptoms may also be caused by chemical changes within the brain, and a lack of vitamins and minerals. Common treatments for PMS range from various lifestyle changes to medications, such as ibuprofen and birth control bills. The OWH recommends exercising regularly, eating fruits and vegetables, getting eight hours of sleep per night, and avoiding salty, sugary and caffeinated foods. It also states that certain vitamins and minerals, such as folic acid, calcium, vitamin B-6 and magnesium, may ease PMS symptoms.
