For two weeks you are irritable, hopeless and not yourself. Then your period comes and it lifts, and you tell yourself you were being dramatic.
Premenstrual dysphoric disorder is a recognised condition in which severe mood symptoms appear in the week or two before menstruation and resolve shortly after it begins. It affects a small but significant minority of menstruating women. It is not ordinary PMS, it is not a bad attitude, and it is treatable — but it is routinely missed because the cyclical pattern is the very thing nobody thinks to look for.
PMS or PMDD
Most women experience some premenstrual symptoms — bloating, tenderness, irritability, low mood. Uncomfortable, manageable, and not a disorder.
PMDD is distinguished by three things:
Severity. The mood symptoms are the dominant feature and they impair functioning. Missed work. Arguments that damage relationships. Days where getting up is genuinely hard.
Specific symptoms. Marked irritability or anger; marked depressed mood, hopelessness or self-critical thoughts; marked anxiety or tension; and pronounced mood swings — alongside the physical symptoms.
Timing. This is what makes the diagnosis. Symptoms appear in the final week or two before the period, improve within a few days of it starting, and are largely absent in the week afterwards. That clear, repeating pattern is the signature.
If symptoms are present all month and simply worsen premenstrually, that is more likely an underlying depression or anxiety condition with premenstrual exacerbation — a different thing, treated differently. Working out which is the reason tracking matters.
The rage nobody talks about
Depression and anxiety in PMDD are documented and expected. The symptom women are most ashamed of, and least likely to mention, is anger.
Not irritation — disproportionate, frightening rage over something trivial, followed a few days later by mortification when the fog lifts and you have to look at what you said to your husband, your children, your sister.

Many women describe living in a repeating cycle of damage and apology, quietly concluding that they are a bad person with poor self-control. They are not. It is a symptom, it has a name, and it responds to treatment.
Why it gets missed here
The cyclical pattern is invisible without tracking. Each month feels like an isolated bad patch. Nobody joins the dots across six months unless someone deliberately looks.
“Every woman goes through it.” The most common response to a Nigerian woman raising premenstrual mood symptoms, from relatives and sometimes from clinicians. It contains just enough truth to close the conversation.
Menstruation is not discussed. Limited conversation between mothers and daughters, and little in clinical settings, means most women have no framework for distinguishing normal from not.
It gets read as character. A woman who is fine three weeks in four and difficult in the fourth gets labelled moody, temperamental, or spiritually unsettled — rather than assessed.
Marital cost. Many husbands experience the cycle without ever learning it is a cycle, and read it as evidence about the marriage.
Our piece on does menstruation affect women’s mental health? covers the broader relationship between the cycle and mood. PMDD is the clinical end of that spectrum.
Tracking, which is the actual first step
PMDD cannot be diagnosed from a single conversation. It requires prospective tracking across at least two consecutive cycles — recording symptoms daily as they happen, not reconstructing them from memory afterwards.
Record each day: mood, irritability, anxiety, energy, sleep, physical symptoms, and where you are in your cycle. A rating out of five is enough. Any tracking app or a notebook works.
Two reasons this matters. It gives a doctor the evidence needed to distinguish PMDD from other conditions, which is otherwise very difficult. And it changes the experience of it: knowing on day twenty-two that this is day twenty-two, and that it will lift, is a genuinely different thing from believing your life has become unbearable again.

What treatment involves
Treatment exists and works for most women. The details are a conversation with a doctor — there are several approaches, they depend on your history and circumstances, and none of them should be self-prescribed. What is worth knowing is the shape of the options:
- Medication. Different classes are used, sometimes continuously and sometimes only in the second half of the cycle. Effective for many women. A doctor’s decision.
- Hormonal approaches. Suitability varies considerably by individual history.
- CBT, which has evidence for premenstrual mood symptoms and helps particularly with the rage, the anticipatory dread and the aftermath — the parts that persist between cycles.
- Sleep, exercise and reducing stimulants, which are supporting measures rather than treatments in themselves, and which do help.
For how the therapy-versus-medication decision is normally approached, see therapy or medication.
Bring your tracking to the appointment and say it plainly: my mood symptoms follow my cycle, here are three months of records, I would like to be assessed for PMDD. That sentence does more than describing the symptoms again.
The safety point
PMDD carries a genuinely raised risk of suicidal thinking in the premenstrual phase. That is well documented and it deserves stating clearly rather than tucking away.
If your low periods include thoughts of ending your life, do not wait for the cycle to turn. Tell a doctor, tell someone close to you, and use our helplines — they are free and available now. Coping with triggers of suicidal thoughts is worth reading today.
Knowing the thoughts are cyclical does not make them safe. It makes them predictable, which is useful for planning — including agreeing in advance with someone you trust what happens during that week.
If it is your wife, your sister, your friend
Learn the pattern. If you can see it coming, you can stop treating each episode as a fresh crisis or a statement about you.
Do not tell her it is just her period. That is the sentence that keeps women from seeking help for a treatable condition. Encourage the tracking, and go to the appointment with her if she wants that.
Frequently asked questions
What is the difference between PMS and PMDD?
Severity, symptom profile and impairment. PMDD involves marked mood symptoms — irritability, depression, anxiety, mood swings — that disrupt functioning and resolve shortly after the period starts.
How is PMDD diagnosed?
By prospective daily symptom tracking across at least two consecutive cycles, showing the symptoms appear premenstrually and resolve afterwards.

Is PMDD a mental illness or a hormonal problem?
Both, in effect. It is understood as an abnormal sensitivity to normal hormonal fluctuation, and it is classified as a depressive disorder.
Can PMDD be treated?
Yes, and most women improve. Options include medication, hormonal approaches and CBT — all decisions for a doctor based on your history.
Is it normal to feel suicidal before my period?
It is a recognised feature of PMDD and it is not something to wait out. Tell a doctor and use our helplines if you are having those thoughts now.
