Snapping at small things that never used to bother you, feeling teary out of nowhere, or noticing your patience has worn thinner than usual? Mood changes and irritability catch a lot of people off guard, especially when nothing in their life has actually changed enough to explain it. We hear this constantly, and the explanation is often sitting in your hormones, not your circumstances.
For women, estrogen is one of the biggest players here. According to Mayo Clinic, changes in mood during perimenopause are common and can include irritability, fatigue, sadness, or anxiety, often a direct result of declining estrogen levels. That swing isn’t constant either; estrogen can fluctuate sharply during this transition, which is part of why the mood shifts can feel so unpredictable.
Men aren’t exempt from this either. According to Cleveland Clinic, testosterone levels can fluctuate for many reasons, and when they drop, men often describe feeling irritable, depressed, weak, or low in energy, symptoms that frequently get written off as stress or burnout instead of being traced back to hormones. Left unaddressed, that mislabeling can drag on for years.
Thyroid imbalances, chronic stress, poor sleep, and blood sugar swings can all layer on top of hormonal shifts, which is why mood changes and irritability are rarely about willpower or just “having a short fuse.”
Progesterone has a naturally calming effect on the nervous system, and it’s often one of the first hormones to drop during perimenopause. As levels fall, that calming buffer weakens, which can leave anxiety, restlessness, and a shorter emotional fuse more room to show up.
Mood is more connected to the gut than most people expect, since a large share of the body’s serotonin is produced there. Chronic inflammation or an imbalanced gut microbiome can interfere with that process, adding another layer on top of whatever your hormones are already doing.

Rather than jumping straight to antidepressants or telling you to manage your stress better, Narges and the team look at what your hormones are actually doing. Estrogen, progesterone, testosterone, thyroid function, and blood sugar are all reviewed, since any one of them can throw your mood off balance. Our hormone replacement therapy program is frequently part of the solution here, calibrated to your specific labs rather than handed out as a blanket fix. Because stress, sleep, and inflammation often tangle together with hormones, this evaluation also draws on our Functional Medicine program to look at the bigger picture.

It can be either, or both at once. That’s exactly why testing matters; it separates what’s hormonal from what’s situational so your plan actually targets the right thing.
Yes. Declining or fluctuating testosterone is a well-documented cause of irritability and low mood in men, even though it’s often mistaken for everyday stress.
Not necessarily. Many patients see meaningful improvement once the underlying hormonal cause is addressed, and your plan is reassessed regularly rather than left on autopilot.
Yes. Perimenopause can start years before periods stop, and mood changes are often one of the earliest signs, sometimes before any change in your cycle.
It depends on what’s driving your symptoms. Some patients notice a shift within a few weeks, while others take longer as your provider fine-tunes the plan.
No. This is one of the most common things we hear, and your provider will treat it as the legitimate medical concern it is, not something to brush off.
