When Mood Shifts Strain Relationships: It’s Not Always ‘Just the Marriage’

It can feel devastating when a marriage or long-term relationship starts to change. Arguments may come more quickly, one partner seems short-fused, or intimacy feels distant. It’s natural to wonder if the relationship itself is failing — but sometimes the root cause isn’t about love at all. It may be about health.

Why Relationships Feel the Strain

When one partner changes in mood, energy, or interest, the relationship absorbs the impact. Common drivers include:

  • Stress and burnout from work, family, or caregiving

  • Hormonal shifts such as low testosterone, perimenopause, or thyroid changes

  • Mental health struggles like depression or anxiety that go unnoticed

  • Withdrawal when one partner feels too tired, irritable, or disconnected

From the outside, it can look like love is fading. But often it’s biology creating emotional distance.

Signs It May Be More Than Just Conflict

  • A partner who used to be patient now snaps easily

  • Intimacy or desire has dropped off with no clear explanation

  • Fatigue or brain fog make it harder to connect

  • One partner pulls away, the other feels rejected

These patterns hurt — but they don’t always mean the relationship is broken.

Hormones, Mood, and Connection

Hormones influence how we show up in relationships.

  • Low testosterone in men and women can cause irritability, fatigue, and loss of interest in intimacy.

  • Perimenopause and menopause can bring mood swings, anxiety, and disrupted sleep.

  • Thyroid imbalance can lead to depression, withdrawal, or short temper.

  • Cortisol imbalance from chronic stress can leave someone “wired but tired,” too exhausted to engage.

When hormones are off, even small relationship stressors feel amplified. Supporting hormone health often restores energy, patience, and connection — making space for the relationship to heal.

Why Getting Checked Matters

Blaming the relationship without considering health overlooks a huge piece of the puzzle. By checking hormones and mood together, couples often discover that what felt like “falling out of love” was really a body out of balance.

My Role

As both a hormone specialist and a psychiatric mental health nurse practitioner, I’m trained to see both sides. I don’t separate mental health from hormone health — I connect them. This approach often means:

  • Less trial-and-error with counseling or medication alone

  • Faster identification of what’s truly driving mood and connection changes

  • Plans that address both the person and the relationship they care about

If you’ve noticed your relationship changing in ways that don’t feel like “you,” it may be time to look deeper.
