Menstrual Irregularities


The average girl starts her period at the age of 12, called Menarche. On average, a normal menstrual cycle lasts for about 21 to 35 days in women. When the cycle becomes less or more than the said number of days or a heavier or lighter than normal period is experienced, it is known as Menstrual Irregularity. It may be associated with abdominal pain or cramping. 

Although it is normal to have irregularity in menstruation a few times after the first period, it takes time for hormones to balance out, and it can vary from girl to girl. Still, if it persists, one must get in touch with a health practitioner. 

Menstrual irregularities can affect a patient's health; of most concern is anemia, which happens due to increased blood loss and causes symptoms like fatigue, paleness, shortness of breath, and feeling constantly tired. It may also pose a threat to fertility. It is managed by finding out and eradicating the underlying disorder.


There can be many causes of menstrual irregularity most common are discussed as follows;


Menstrual irregularities are of different types;

  • Amenorrhea: It is the absence of menstruation.
  • Oligomenorrhea: Having light periods
  • Menorrhagia: It is excessive (heavy) bleeding during periods 
  • Dysmenorrhea: It is a period associated with pain 
  • Metrorrhagia: It is abnormal bleeding that is not associated with menstruation. It can occur in between the periods. 
  • Premenstrual syndrome: It is the time before having menses, during which women experience pain and cramps in the abdominal area, bloating, irritability, acne, cravings, and excessive fatigue. 
  • Premenstrual dysphoric disorder (PMDD) comprises more serious mood changes like irritability and depression a week before menses.
