Estrogen in Perimenopause: Why You Feel So Different Lately

If you’ve been feeling emotionally all over the place lately…more anxious,more irritable,more exhausted,less motivated,or just not like yourself altogether…

There’s a very good chance estrogen fluctuations are playing a role.

One of the biggest things I want women to understand is this:

Your hormones impact so much more than just your reproductive system.

They affect:

• your mood

• your energy

• your motivation

• your sleep

• your brain

• your stress resilience

• your metabolism

• and even how connected you feel to yourself

And when estrogen starts fluctuating during perimenopause, it can feel like your entire system is sending mixed signals.

What Estrogen Actually Does

I like to think of estrogen as:

• your energy hormone

• your stimulating hormone

• your lubricating hormone

While progesterone tends to be more calming and grounding, estrogen helps regulate:

• motivation

• focus

• mood

• happy neurotransmitters like serotonin and dopamine

So when estrogen becomes too high, too low, or wildly fluctuates, that’s when things can start feeling a little chaotic.

And that’s why so many women suddenly feel like they don’t recognize themselves anymore.

What Low Estrogen Can Feel Like

Low estrogen often feels like depletion.

Women commonly describe it as:

• flat mood

• exhaustion

• low motivation

• brain fog

• feeling emotionally “blah”

• feeling disconnected from themselves

And physically, it can show up as:

• hot flashes

• night sweats

• vaginal dryness

• joint pain

• thinning hair

• dry skin

• sleep disturbances

• increased UTIs

• weight gain around the middle

One thing I personally started noticing was joint pain.

I was hiking with friends, and suddenly my knees were hurting, even though I’d never really had knee issues before.

That’s one of those things women often don’t connect back to hormones.

Frozen shoulder is another very common symptom connected to estrogen decline.

Why Estrogen Impacts So Many Areas of the Body

Estrogen helps support many important functions in the body, including the production of serotonin and dopamine, which influence mood, motivation, and emotional well-being. It also supports healthy blood flow to the brain, collagen production for skin elasticity and a more youthful appearance, bone health, and the health and lubrication of vaginal tissues.

This is why women may suddenly notice more wrinkles, droopier skin, dryness, brain fog, emotional flatness, weaker bones, and mood changes as estrogen levels begin to decline during perimenopause and menopause. Annoying, I know. 

And one of the most frustrating symptoms for many women is the weight gain around the belly that often happens as estrogen declines.

But you haven’t changed anything, yet your body is changing, and that is incredibly discouraging.

The “I Don’t Care” Phase

One thing I joked about is I’m in my “IDAF phase.” 😂

You know that phase where you suddenly don’t want to:

• socialize

• go anywhere

• tolerate nonsense

• overextend yourself anymore

There’s actually a hormonal reason for some of that.

When estrogen drops, many women feel flatter emotionally and less socially driven than they used to.

Things that once excited you suddenly feel exhausting.

What High Estrogen Can Feel Like

Now, on the flip side, high estrogen can create a very different set of symptoms.

This may look like:

• bloating

• water retention

• breast tenderness

• heavy periods

• mood swings

• headaches

• migraines

• anxiety

• fibrocystic breasts

• weight gain around the hips and thighs

For me personally, moodiness and irritability around my cycle were huge symptoms in earlier perimenopause years when estrogen fluctuations were more intense.

Why You Feel Like You’re on an Emotional Roller Coaster

One of the reasons perimenopause feels so emotionally intense is because progesterone and estrogen are supposed to work together.

In early perimenopause:

• progesterone usually starts declining first

• estrogen starts fluctuating wildly up and down

And when those hormones are out of sync? Women feel:

• anxious

• irritable

• emotionally reactive

• exhausted

• emotionally overwhelmed

• unlike themselves

Your nervous system is trying to keep up with constantly changing chemistry.

The Symptoms Can Feel Similar, But Different

One thing that makes hormones so confusing is that low progesterone and low estrogen can sometimes look similar.

For example:

Low Progesterone Often Feels Like:

• anxiety

• irritability

• poor sleep

• feeling wired and tired

• breast tenderness

• heavier periods

Low Estrogen Often Feels Like:

• flat mood

• sadness

• depletion

• night sweats

• vaginal dryness

• lighter periods

• brain fog

• loss of motivation

And because hormones are constantly fluctuating in perimenopause, symptoms can change week to week,  and sometimes even day to day.

Your Hormone Fluctuations Are Not Your Fault

I think one of the most important things women need to hear is this:

You are not failing because your body is changing in midlife.

You are not weak because stress feels harder, or lazy because your motivation changed.

Your hormones are shifting and that impacts almost everything.

Ways to Support Estrogen Naturally

The good news is that there are things you can do to help support your body during this transition.

Some foundational things that can help include:

Supporting Liver Health

Your liver helps process and clear excess estrogen from the body.

Some helpful foods include:

• leafy greens

• broccoli

• kale

• arugula

• lemon water

Stabilizing Blood Sugar

This one matters so much for mood and hormones. Blood sugar is simply the amount of fuel in your bloodstream. Your brain runs mostly on that fuel. When Blood sugar is steady, you feel calm. When it drops too low, your brain senses danger, and your mood, energy, and emotions can shift quickly.

That means:

• eating enough protein

• not skipping meals

• reducing ultra-processed foods

• limiting excessive sugar and refined carbs

Lowering Stress

Your nervous system needs support during this season.

Simple things like:

• walking

• breathwork

• getting outside

• going to bed earlier

• slowing down

can make a bigger difference than many women realize.
