Mood Swings in Women – What are the causes?

Mood swings are sudden changes in the mood of a person. These are phases of sudden or unpredictable changes in a person’s behavior. In such phases, the emotional wellbeing of a person might switch amidst periods of depression and happiness. Whilst the sudden mood change might be a reaction to any situation or event that a person might be facing, but mood swings at times can occur without any apparent reason.

Mood Swings in Women:

Women tend to suffer from dramatic changes in mood because of certain hormonal changes that trigger when they enter their reproductive phase.


Start of puberty in young women is an indication of menstruation. The physical changes occurring during this time may trigger mood swings in young women. At the very first onset of menstruation, the body of a girl undergoes a sequence of changes. Thickening of the endometrial lining and menstrual bleeding are certain cyclic changes occurring each month because of the hormonal interactions. This reoccurring cycle is known as menstrual cycle and it usually lasts for 28 -35 days. Young women might undergo mood swings because of PMS or premenstrual syndrome. A cluster of emotional and physical signs that might occur prior to the commencement starts distinguishes this syndrome.


Though pregnancy is a matter of joy, women might feel emotional because of several physical changes taking place during this period. Women might feel overstressed due to weight gain, morning sickness, fatigue and several other fluctuations taking place during pregnancy.

Many times, women become anxious about their lives post pregnancy. Fluctuations in the levels of hormones post pregnancy might also make women more prone to undergoing postpartum depression. Lack of concentration, sleep deprivation, anxiety and depression are few signs of this particular condition. Postpartum psychosis, which is an uncommon yet serious depression type and a woman suffering from this condition, may harm the baby or herself.

Chemical Imbalance:

Neurotransmitters released by our brain are messengers accountable for amending the emotional and mood responses. Any imbalance in neurotransmitter levels may cause mood swings or other mood problems. Prolonged intake of some drugs, alcohol or drug abuse, exposure to ecological toxins and prolonged stress are some major factors that cause chemical imbalance.


Women suffering from prolonged stress are highly prone to health problems. Few factors are accountable for stress and it can trigger due to problems at work, financial issues, marital concerns, health problems, emotional problems and disastrous relationships. In case you fail to resolve the factors causing stress, you might suffer from mood swings or depression.

Menopause and Perimenopause:

Menopause infers to the end of menstruation. A woman is said to reach menopause stage if she does not had a single menstruation period for a whole year. Perimenopause is a kind of intermediary period, which precedes the menopause stage. The physical discomfort resulting during this period might lead to stress, which might in turn cause mood swings in them.
