Although PMS has been reported in the medical literature since the 1930's its validity as a 'medical condition' is a hotly debated subject. Many worry that it will be used to prove women too emotionally and physically unpredictable for certain jobs or responsibilities. Some women experience purely emotional changes, while others feel physical discomfort, or a combination of both. PMS is not a normal part of the monthly cycle, and many women do not experience any problems or very minor ones. The most common symptoms are mood swings, irritability and bloating.
Water retention can cause tender and swollen breasts, hands and feet, and if extreme, weight gain.
Food cravings and strong appetite are common. Skin problems also tend to surface at this time. In some cases, emotional symptoms can be quite disruptive, causing mental fatigue, forgetfulness, insomnia or depression . Other common problems include headaches, abdominal cramps, backaches, physical exhaustion and dizziness. While hormonal changes are normal throughout the menstrual cycle, recurring symptoms of PMS occur when these changes are extreme and unbalanced.
