Many people who have periods experience feelings of tension, anger, fatigue and depression just before and during the first days of their menstrual period. This is called premenstrual syndrome (PMS) and is probably caused by the change in hormone levels.

 

In most people with PMS, symptoms will not be severe enough to require treatment, but some will need to discuss their symptoms with a doctor. Sometimes symptoms can be improved by avoiding some types of food, such as coffee and foods high in salt.
