PMDD, ADHD, and Endometriosis: Why These Conditions So Often Show Up Together

If you’ve ever wondered why you feel more emotional, unfocused, and in pain during your time of the month, you’re not imagining a connection.

Many women experience premenstrual dysphoric disorder (PMDD) or premenstrual exacerbation (PME), ADHD, and endometriosis together, often without anyone connecting the dots. Instead, the symptoms of each condition are treated and considered in isolation.

This results in poor treatment outcomes and misdiagnosis. This is especially true for BIPOC women who are more likely to be misdiagnosed with other mental health conditions, such as bipolar disorder. This misdiagnosis is often due to the severity and cyclic nature of symptoms that mimic the features of other conditions.

Research shows that these conditions share biological, neurological, and hormonal pathways that help explain why they are so frequently comorbid and why together they can be so debilitating when left untreated.

Let’s talk about what we know and what it means for your care.

What Is PMDD?

PMDD is a severe, hormone-sensitive mood disorder tied to the luteal phase of the menstrual cycle. PMDD can involve:

• Intense depression or anxiety

• Irritability or rage

• Hopelessness or suicidal thoughts

• Cognitive fog and overwhelm

• Heightened pain sensitivity

Interestingly enough, PMDD is not caused by abnormal hormone levels, but by an abnormal sensitivity to normal hormonal fluctuations, particularly with changes in estrogen and progesterone levels.

PME (Premenstrual Exacerbation)

PME (premenstrual exacerbation) is a related condition that is diagnosed when you have another mental health condition that worsens at different points in your cycle. For example, let’s say you were diagnosed with depression. During your luteal phase, your depressive symptoms worsen (this can look like not being able to get out of bed, uncontrollable crying, and fits of rage) but improve after your period ends. Improvement looks like returning to your baseline symptoms with depression once your period ends (i.e., feeling calmer, feeling less hopeless or sad, and feeling more clearheaded).

PMS (Premenstrual Syndrome)

PMS (premenstrual syndrome) is less severe and shares a similar symptom profile to PMDD.

The PMDD–ADHD Connection

Research increasingly shows that people with ADHD are significantly more likely to experience PMDD. Why?

Several shared mechanisms stand out:

1. Dopamine Dysregulation

ADHD involves lower baseline dopamine activity. Estrogen directly influences dopamine production and transport. When estrogen drops in the luteal phase, dopamine availability drops further and causes worsening symptoms:

• Emotional regulation challenges

• Executive functioning deficits increase

• Motivation decreases

• Impulsivity increases

For someone with ADHD, this hormonal shift can feel like their coping tools disappear overnight. Medication may need to be prescribed in order to help women from being debilitated. Zoloft and Prozac are both FDA-approved to treat PMDD and can be life-changing for women who are struggling to manage their symptoms. There are two dosing models as well: continuous (taken on an ongoing basis) and intermittent (taken for 2 weeks during the menstrual cycle only).

2. Nervous System Sensitivity

Both ADHD and PMDD involve heightened nervous system reactivity. This can amplify:

• Emotional intensity

• Emotional outbursts

• Sensory overload

• Rejection sensitivity

• Stress responses (e.g., vasovagal syncope, which is triggered by the vagus nerve being overstimulated in response to stress)

What may look like “mood swings” is often a nervous system under real biological strain, unable to recalibrate.

Endometriosis and Mental Health

Endometriosis adds another layer — and it’s not just about pain.

Endometriosis is increasingly understood as a whole-body inflammatory condition, not simply a reproductive one. It’s associated with:

• Chronic inflammation

• Immune system dysregulation

• Estrogen dominance or altered estrogen signaling

• Central sensitization (the nervous system becoming more reactive over time)

Chronic pain and inflammation affect the brain. They change how stress is processed, how emotions are regulated, and how safe the body feels.

This helps explain why many people with endometriosis also experience:

• PMDD

• ADHD-like symptoms (or worsening of existing ADHD)

• Anxiety, depression, or trauma responses

Pain is not just physical; it’s cognitive and experienced by the brain. We must not forget that the brain and body are in constant conversation and seek to work together.

The Common Thread: Hormones, Inflammation, and the Brain

When we zoom out, a clear pattern emerges. PMDD, ADHD, and endometriosis intersect at:

• Hormone sensitivity (not necessarily hormone imbalance)

• Dopamine and serotonin pathways

• Chronic inflammation

• A sensitized nervous system

• Higher trauma and stress exposure over time

This combination can make people feel as though they are “losing themselves” every month, especially when their experiences are dismissed, misdiagnosed, or left unmanaged.

Why This Matters for Treatment

When these conditions are treated in isolation, people often feel like nothing fully works.

Effective care usually requires:

• Trauma-informed mental health treatment

• Hormone balancing therapies (e.g., seed cycling, supplements, and birth control)

• Support for executive functioning and ADHD traits

• Validation of chronic pain and medical trauma

• Collaboration between medical and mental health providers

Women deserve providers who are not only knowledgeable about this relationship. We deserve providers who can address the issue from multiple angles to promote effective management.

When Faith and Biology Feel at Odds

For Christian women, this intersection can carry a unique spiritual burden.

Many are striving to live as “new creations in Christ,” yet find themselves cycling through despair, irritability, brain fog, or emotional overwhelm month after month. This can lead to shame, guilt, confusion, and self-doubt:

• Why did I just curse him out? I thought I had stopped doing that since I got saved.

• There must be something wrong with me. Why can’t I just do what God expects of me when I feel like this?

• I keep praying and asking God to change me, but I keep doing the same thing over and over. He must be sick of me asking him. He must be ashamed of me too.

But the presence of PMDD, ADHD, and endometriosis literally impairs your ability to maintain your deportment. And scripture reminds us that transformation does not erase the flesh that fights against our Godly nature. We are renewed in Christ, but we are still imperfect. We still live in bodies affected by hormones, pain, inflammation, and trauma. God knows this because He formed you and knew you before you were even born. Caring for your mental health and honoring biological limits are essential to survive and live the life you were meant to live. Struggling with this because these comorbid conditions are so deeply impactful shouldn’t be an indictment on your character. For many women, healing begins not with trying harder on your own, but with releasing condemnation and allowing our Heavenly Father to show up strong in our weaknesses.

An Invitation to Join the Discourse

Do you live with one or all three of these conditions? If so, you are not alone. Even your lovely author struggles with all three!

If you live with PMDD, ADHD, endometriosis, or any combination of the three, your experience isn’t as outlandish as you think. You are not “too much.” You are responding to a body and brain that are working incredibly hard to survive. This conversation is still evolving, and your voice matters so much to me. I look forward to having a rich discussion with you here on this post or over on my social media handles (@cheerfulheartmhcpllc on Instagram and Facebook).

To keep the conversation going, consider these questions. More questions on Instagram and FB.

• What patterns have you noticed in your own cycle, mood, focus, or pain?

• What do you wish your providers understood?
