About this guide
This guide brings together clinical guidance, research and practitioner perspectives on premenstrual dysphoric disorder, known as PMDD. My aim is to make the information easier to understand and help women and girls recognise when they may need more support.
It is for general education. It cannot tell you whether you have PMDD or provide a personal diagnosis or treatment plan. Please discuss symptoms, medicines and supplements with an appropriately qualified healthcare professional. If you are having thoughts of self harm or suicide, seek urgent support.
What is PMDD?
Many people notice changes in the days before a period. With PMDD, emotional symptoms can be much more intense. They may affect relationships, work, school, parenting and the ability to manage everyday life.
Symptoms usually appear after ovulation, during the luteal phase, and improve shortly after the period begins. A woman may feel like herself for part of the month and then experience a striking change before her next period.
PMDD does not necessarily mean that hormone levels are too high or too low. During the luteal phase, progesterone rises and oestrogen has a smaller second rise. Both then fall before menstruation. Research suggests that people with PMDD are more sensitive to these normal changes.
PMDD can affect teenagers as well as adult women. It should never be dismissed as someone being dramatic, difficult or simply “bad at coping”.
The liver, gut and oestrogen recycling loop
Oestrogen does not simply disappear once the body has used it. The liver processes oestrogen and its metabolites, and some are sent into bile and on to the gut. Some leave the body in the stool, while others leave through the urine. In the gut, certain bacterial enzymes can release oestrogens from the forms prepared for removal. Some can then be absorbed again and return to the liver. This is called enterohepatic recycling.
That loop is one reason to look at liver function, bile flow, digestion and regular bowel movements when exploring the wider hormone picture. If oestrogens are recirculated rather than eliminated, they may contribute to greater oestrogen exposure in some circumstances. People sometimes call an imbalance between oestrogen and progesterone oestrogen dominance. It is important to understand the whole pattern rather than assume that one symptom or one stool test proves this is happening.
We can work on the foundations that help the liver and digestive system do their jobs, including adequate nourishment, fibre that suits your gut, and addressing constipation or other digestive concerns. A DUTCH test can often give useful detail about oestrogen and progesterone metabolites, while a comprehensive stool analysis may help us look more closely at gut health and, where included in the test, bacterial beta glucuronidase activity. We would interpret these findings alongside symptoms and cycle history before deciding on individual support.
Neither test diagnoses PMDD or proves that oestrogen is recirculating excessively. This recycling loop may be relevant to someone's overall hormone health, but it has not been established as the cause of PMDD. PMDD can reflect sensitivity to normal hormone changes, so severe mood symptoms still need their own assessment and support.
How might it feel?
PMDD can look different from one person to another. Emotional symptoms may include:
- Sudden mood changes or tearfulness
- Irritability or anger that feels difficult to control
- Anxiety, tension or panic
- Low mood, hopelessness or harsh thoughts about yourself
- Feeling overwhelmed
- Difficulty concentrating
- Losing interest in things you normally enjoy
Physical changes may include poor sleep, exhaustion, food cravings, breast tenderness, bloating, headaches or muscle and joint pain.
The most useful clue is the pattern. When do these symptoms begin? When do they ease? Is there a part of the month when you feel substantially better?
PMDD is serious, but it is also important not to assume that every difficult premenstrual symptom is PMDD. Other health concerns may need attention too.
Is PMDD becoming more common?
More women and girls are talking about PMDD and sharing their experiences. This may mean that people who were previously dismissed are finding a name for what they have been going through and asking for help. We do not yet know whether PMDD itself is becoming more common.
Keeping a symptom diary
There is no single blood test that diagnoses PMDD. The usual approach is to record symptoms every day for at least two menstrual cycles.
A diary does not need to be complicated. Note the first day of each period and give a daily score for mood, anxiety, irritability, energy, sleep and physical symptoms. It also helps to note how well you could work, study, care for others and enjoy your usual activities.
Include any thoughts of hopelessness or self harm, along with medicines, supplements or hormonal contraception you are using. The aim is to see whether symptoms repeatedly become severe before a period and then clearly improve afterwards.
You can take this record to your GP or another suitably qualified clinician. It gives you both something more useful to discuss than trying to recall your most difficult days from memory.
PMDD or an existing problem that gets worse before a period?
This distinction matters.
In PMDD, the most troubling symptoms are mainly tied to the premenstrual part of the cycle. In premenstrual exacerbation, sometimes called PME, a condition is present throughout the month but becomes worse before a period.
For example, someone living with anxiety, depression, migraine, chronic pain or another condition may notice a premenstrual worsening. It is also possible to have an underlying condition and a separate PMDD pattern.
A daily diary and a full assessment can help make sense of what is happening. This is particularly important if symptoms continue throughout the month. Depending on the person’s history, a clinician may also consider concerns such as thyroid problems, anaemia, heavy or painful periods, medication effects or perimenopause.
PMDD at different stages of life
Teenagers
A teenager’s distress deserves to be heard. School demands, sleep, friendships, family life and the early years of menstruation can all make it harder to see a clear pattern.
It is worth recording symptoms without jumping to a diagnosis. Notice any changes in school attendance, withdrawal from friends, difficult periods, sleep, eating or safety. A young person who talks about self harm or self loathing needs immediate support. Treatment decisions for teenagers need an individual medical assessment.
Adult women
PMDD can affect confidence, relationships, work and family life. Some women notice that arguments, hopelessness or the urge to make a major life change recur at much the same point in each cycle.
Recognising that pattern can help someone seek support and plan for more difficult days. It does not mean that their feelings or the problems in their life should simply be dismissed as hormones.
Pregnancy, after childbirth and perimenopause
The usual PMDD pattern depends on menstrual cycling, so it does not continue in the same way during pregnancy. Symptoms may return when cycles resume after childbirth. Low mood or anxiety after childbirth also deserves attention and assessment in its own right.
During perimenopause, periods and ovulation can become less predictable. Sleep problems, hot flushes and other changes may overlap with premenstrual symptoms. A diary can still help, but new or persistent symptoms should be assessed rather than automatically labelled PMDD.
What help is available?
There is no need to work through severe symptoms alone. You are not the only girl or woman who struggles. Reaching out is the first step. Treatment is individual, and sometimes more than one approach is helpful.
Talking therapies
Cognitive behavioural therapy, known as CBT, may help with coping, the strain symptoms place on relationships and the dread of knowing another difficult week may be coming. Offering therapy does not mean that PMDD is imaginary or that someone has caused it through the way they think.
Medicines
Medicines called selective serotonin reuptake inhibitors, or SSRIs, have some of the strongest evidence for PMDD symptoms. A prescriber may recommend taking one every day or during a particular part of the cycle. The decision depends on the person, other health conditions, possible side effects and whether pregnancy is planned.
Some combined contraceptive pills, particularly a studied formulation containing drospirenone, may help some women. Others find that hormonal contraception worsens their mood. A prescriber needs to assess whether a particular option is suitable.
For severe symptoms that have not improved with initial treatment, specialist services can discuss other approaches. These are decisions for specialist care.
Everyday support
Regular meals, enough sleep, movement you enjoy and ways to reduce stress may help support wellbeing. It can also help to tell someone you trust when your difficult days tend to occur and what sort of support is useful.
These steps can sit alongside medical treatment. They should not be presented as a cure for PMDD or as a reason to delay care when symptoms are severe.
Food and supplements: what do we know?
There is no single proven “PMDD diet”. Eating regularly and getting enough nourishment is a sensible foundation, especially if symptoms are accompanied by poor sleep, cravings or skipped meals.
Calcium has some of the clearest evidence among the nutritional approaches discussed in guides to premenstrual disorders. Food intake and any supplements need to be considered together.
You may also read about magnesium, vitamin B6, vitamin D, omega 3 fats, saffron or the herb Vitex, but the evidence varies. There is no established supplement plan that suits everyone.
Supplements can also cause side effects or interact with medicines, so it is sensible to check before taking them.
Iodine, progesterone creams and products promoted for “oestrogen detoxification” are not established PMDD treatments and do not suit everyone. A personal supplement plan should take account of symptoms, medical history, medicines and nutritional needs.
What about histamine?
Some practitioners and people living with PMDD have noticed that allergies, hives, flushing, headaches or food reactions seem to change across the menstrual cycle. This is worth recording if it happens to you.
Researchers are interested in how hormones and immune signals interact. At present, though, histamine intolerance or mast cell activation has not been established as the cause of PMDD. Low histamine diets, antihistamines, quercetin and DAO supplements are not proven PMDD treatments.
If you have a suspected allergy or recurring reactions, those symptoms deserve their own assessment. Keeping a record of what happens, when it happens and whether it also follows your cycle may help you discuss it with a healthcare professional. Avoid removing large numbers of foods without a clear reason and appropriate support.
Looking at naturopathic perspectives
Practitioners such as Lara Briden, Aviva Romm and Jolene Brighten have written about menstrual health from naturopathic or integrative perspectives. Their work may raise useful questions and help people feel heard.
Ideas discussed in this area do not all have the same level of evidence. In particular, histamine protocols, iodine, progesterone and high doses of vitamin B6 should not be treated as established PMDD treatments. It is reasonable to be curious about emerging information, but treatment plans need appropriate guidance.
When to seek help
Please speak to a GP or another appropriately qualified healthcare professional if premenstrual symptoms are disrupting your life, relationships, education or work. You do not need to wait until you have completed two cycles of diary entries to ask for help.
Seek prompt assessment if symptoms are severe, continue throughout the month, or occur alongside heavy bleeding, severe pain or another worrying physical symptom.
Thoughts of self harm or suicide need urgent support. If you or someone else is in immediate danger, call emergency services now. You are not alone.
A gentle place to start
If this guide sounds familiar, begin by writing down what happens each day and when your period starts. Note the difficult days and the days when you feel more like yourself.
Bring that record to a healthcare appointment. Tell them clearly how the symptoms affect your life. PMDD can be difficult to live with, but your experience deserves to be taken seriously, and there are ways to get support.
