Problems that call for immediate medical attention are:

• Bleeding between periods
• Amenorrhea: lack of periods – periods that may have started and stopped, or not started at all
• Dysmenorrhea: painful menstruation, often with cramps
• Areomenorrhea: very rare menstruation
• Menorrhagea: exceptionally heavy periods

These anomalies in the period may be caused by:

• 90% of anomalies in menstruation are due to hormonal problems.
• Psychological disturbances caused by changes in a woman’s environment (e.g. moving to a new country, home, office), personal problems, etc.
• Strict and unbalanced diets with rapid weight loss.
• Use of drugs.
