How is PMDD diagnosed?

To get a diagnosis of PMDD the best place to start is visiting your doctor. To help them understand your symptoms your doctor may:

Ask you to keep a detailed record of your symptoms for at least two months, to see if your symptoms have a pattern over time. This may be in your diary or they may give you some daily questionnaires to fill out.
Ask you about your medical history, such as any history of mental health problems.
Ask about your lifestyle, such as if you smoke, drink alcohol or are overweight.
Give you a physical examination along with some blood tests, so that they can rule out other medical problems.

When you're asked to keep a record of your symptoms over several months, getting a diagnosis can feel like a very slow process. This can be frustrating if you're having to wait a long time to get treatment. Our page on self-care for PMDD has some ideas you can try in the meantime.

"I tracked my symptoms over three months, and saw that there was a direct correlation between my monthly cycle and my mental health."

What if I'm struggling to get a diagnosis?

Some people find getting a diagnosis of PMDD can be really difficult. This might be because it can take a long time to realise that your symptoms follow a cycle and that they are linked to your period. It can also be because PMDD is not very well known, even amongst health professionals. It can be really upsetting and frustrating if you feel like your doctor is overlooking something, or not taking you seriously. There are things you could try though:

Keep your own detailed record of your symptoms over time. If you have a smartphone, you can download the app Me v PMDD to track your symptoms and cycle. You could also do this in a diary or you can download mood charts from the internet. The more information you collect over a long period of time, the better prepared you'll be to explain your symptoms to you doctor.
Take the PMDD treatment guidelines with you to your GP appointment. The National Institute for Health and Care Excellence (NICE) and the National Association for Premenstrual Syndrome (NAPS) both provide detailed, step-by-step guidelines on the diagnosis and treatment of PMS . These include severe PMS, which is another term for PMDD. You can download these from their websites.
Ask at your GP surgery if you could speak to a doctor who specialises in mental health, gynaecology or endocrinology. Gynaecology is the branch of medicine that deals specifically with the female reproductive system, and endocrinology deals with hormones.
Consider finding an advocate. An advocate is someone who can come to appointments with you and help make sure people listen to you. See our pages on advocacy for more information.

What if I'm trans or non-binary and think I might have PMDD?

If you are trans or non-binary you can still get PMDD. If you are trans or non-binary, PMDD may increase feelings of discomfort with the gender you were assigned at birth.

You may also find it difficult to talk to a GP, particularly if you have had a bad experience in the past. You have a right though to be listened to, respected and given the right support for you.

For information on how doctors should address your health needs if you're trans or non-binary, see the General Medical Council (GMC)'s guidelines on trans healthcare. Remember that if you feel you've been treated unfairly by a healthcare professional, you can complain.

If you think you might have PMDD and need support in finding trans or non-binary services to help you, see our pages on LGBTIQ+ mental health support.

"When the suicidal feelings became unbearable, I realised I had to take action. I decided I had to explain it properly to the doctor as my life depended on it, so I brought my mum with me and told the whole story. I got referred to a gynaecologist and now that I'm under hormonal treatment my symptoms are much better."

Premenstrual Exacerbation

Your doctor might consider whether you have Premenstrual Exacerbation (PME) rather than PMDD. This is when existing mental health problems are made worse during the luteal phase of your menstrual cycle. In PME, your symptoms will continue even after your period but at a lower intensity. This is why tracking your symptoms throughout your cycle is important for a correct diagnosis.

The International Association for Premenstrual Disorders (IAPMD) has more information on PME on their website.

Misdiagnosis with other mental health problems

Sometimes people with PMDD can be wrongly diagnosed with other mental health problems such as depression or bipolar disorder. This is because they share some of the same symptoms. Also, if you have any other physical or mental health problems, experiencing PMDD at the same time can make the symptoms worse.

For these reasons, it is really important to keep a clear and detailed record of how you're feeling over time, because with PMDD your symptoms will follow a regular monthly pattern.

If you're worried that a diagnosis you've been given doesn't fit your experiences, it's important to discuss it with your doctor so you can make sure you're getting the right treatment to help you.

See our pages on seeking help for a mental health problem for more information on getting the most from your doctor and making your voice heard.

"I saw five different (male) GPs before they accepted my suggestion that my problems were connected to my cycle and I eventually came away with a factsheet about 'PMS' in my hand. It wasn't until recently that I sat in front of a doctor who didn't look at me as if I was mad when I said that my menstrual cycle was driving me insane."
