Why PMDD is far more than a hormonal imbalance, according to a gynaecologist

For many women, the days leading up to a period can bring an overwhelming wave of emotional distress — depression, anxiety, intense anger and mood swings that feel wildly disproportionate to the situation.

Physical symptoms such as fatigue, bloating and a general heaviness in the body can compound the experience, making even routine tasks feel unmanageable.

For years, these symptoms have been collectively normalised under the umbrella of PMS, or premenstrual syndrome — something women have long been expected to endure in silence.

But when the emotional turmoil becomes severe, recurring and disruptive enough to affect work, relationships, sleep or day-to-day functioning, it may in fact be pointing to a far more serious clinical condition: Premenstrual Dysphoric Disorder, or PMDD.

Understanding PMDD

To better understand the condition, HT Lifestyle spoke with Dr Thejaswini J, consultant obstetrician and gynaecologist at Motherhood Hospitals, Electronic City, Bengaluru.

She explained that PMDD occurs during the luteal phase of the menstrual cycle — typically in the week before a period begins — and can produce extreme emotional distress that goes well beyond ordinary premenstrual mood changes.

One of the most persistent misconceptions about PMDD is that it is simply the result of a hormonal imbalance. Dr Thejaswini was clear that this explanation falls well short of the full picture.

"Most blood tests indicate that women maintain normal biological levels of oestrogen and progesterone throughout their menstrual cycle," she explained.

"Rather, the problem is an increased nervous system sensitivity to the normal fluctuations of these hormones. While the level of progesterone increases and then drops precipitously, it affects the neurotransmitters in the brain, particularly serotonin, which controls mood, sleep patterns, and pain."

It is this drop in hormones that acts as a chemical trigger, plunging those affected into intense anxiety, despair or acute rejection sensitivity — a state in which ordinary situations can feel catastrophic.

When does PMDD occur?

PMDD follows a recognisable pattern. Symptoms emerge during the luteal phase — after ovulation but before menstruation begins — and ease markedly once a period starts.

This cyclical nature is what sets PMDD apart from generalised mood disorders, where symptoms tend to persist throughout the month rather than following a hormonal rhythm.

Dr Thejaswini described the experience in stark terms: "This 'on-off' switch creates a cycle of monthly trauma, whereby the individual will have two weeks of crisis and two weeks of damage control to fix the damage done in the first two weeks."

This pattern makes symptom tracking an essential tool. If intense sadness, anxiety, anger, irritability or rejection sensitivity appear predictably in the days before a period and lift once bleeding begins, PMDD may be the underlying cause.

Crucially, the condition is distinguished from ordinary mood swings by the severity of its impact — PMDD is disruptive enough to seriously affect work, relationships, sleep and daily life.

Treatment options

Treatment for PMDD focuses on stabilising the brain's neurochemical responses to hormonal fluctuations, rather than simply addressing the hormones themselves.

"The treatment involves stabilization of the neurochemical responses to prevent the brain from reacting in such a violent manner to the changing tide of hormones," Dr Thejaswini said.

This may involve SSRIs — Selective Serotonin Reuptake Inhibitors — which are effective for PMDD even when taken only during the luteal phase, rather than continuously.

In some cases, medications that suppress ovulation altogether may be recommended to eliminate the hormonal fluctuations that trigger symptoms in the first place.

The broader message from experts is clear: PMDD is a serious clinical condition, and the intense premenstrual symptoms many women experience should no longer be normalised or dismissed as something simply to be endured.
