Why it matters: Knowing what triggers those emotional rollercoasters, how long they tend to last, and what you can do about them puts you back in control of your health journey.

Why Swings Happen

What hormones are we talking about?

When you start hormonal therapy youre mainly dealing with estrogen, progesterone, andif youre a transwomantestosterone. Each of these hormones plays a role in the brains chemistry, especially in the production of serotonin and dopamine, the feelgood neurotransmitters. A sudden influx or dip can feel a bit like turning a dial up and down on an old radio: you hear the static before the signal settles.

How do fluctuating levels affect the brain?

Estrogen tends to boost serotonin, which can lift mood, while progesterone can have a calming, slightly sedating effect. When the balance shifts quickly, the brain receives mixed messagesone moment you feel energetic, the next you might feel irritable or tearful. A study published in found that women on hormone replacement therapy (HRT) had a modest, shortterm increase in reported mood changes, most of which resolved within three months.

Typical timeline: when do swings start and fade?

Most people notice mood changes in the first two weeks. By weeks three to four the body starts to adjust, and many report a steadying of emotions. If youre still feeling like a mood seesaw after 12 weeks, its worth checking in with your clinician.

Mood swings HRT MTF

Transgender women often start with higher doses of estrogen, especially if theyre using injectable forms. These injections can cause peaks and troughs that feel like emotional waves. A guide from UCSFs Transgender Care Program notes that adjusting the route (e.g., switching from injection to a transdermal patch) can smooth those peaks.

Other risk factors

Having a history of depression or anxiety, high stress levels, poor sleep, or even excess caffeine can make mood swings more noticeable. Think of it like adding extra spice to an already hot disheverything becomes more intense.

Realworld example

Take Samantha, 52, who began HRT for severe night sweats. In week three she described her emotions as a rollercoaster that never stopped. After a quick chat with her doctor, the dose was lowered and a lowdose SSRI was added. By week eight, the swings had mellowed, and she could finally sleep through the night again.

• Adjusting the dosesometimes a smaller amount does the trick.
• Changing the delivery methodpatches or gels give a steadier hormone level than pills or injections.
• Adding a lowdose antidepressant or antianxiety medication for a short bridge period.
