Is it anxiety — or something else?

Anxiety isn’t always in your head. We explore hormones, metabolism, and root causes before rushing to label or treat.

Updated this week

If you’ve ever been told “it’s just anxiety” — but something inside you knew it was more — you were probably right.

At Fishtown Medicine, we take a step back and ask:

What else could be driving this?

Because anxiety is real — but it’s not always the root cause. Sometimes it’s a signal from deeper systems that need attention.


🧠 Symptoms that look like anxiety, but aren’t always:

  • Racing heart

  • Chest tightness

  • Shakiness or dizziness

  • Brain fog

  • Irritability or overwhelm

  • Trouble falling or staying asleep

  • Morning dread or mid-day crashes

These can be caused by emotional stress — or by hormones, blood sugar swings, nutrient imbalances, or nervous system dysregulation.


🧪 What we look for beyond mood:

1. Thyroid health

  • Overactive thyroid (hyperthyroidism or Hashimoto’s flares) can mimic anxiety

  • Underactive thyroid can create fatigue-driven anxiety or looping thoughts

We check:
TSH, Free T4, Free T3, Reverse T3, and thyroid antibodies


2. Blood sugar and insulin resistance

  • Crashes in blood sugar (reactive hypoglycemia) can cause panic-like symptoms

  • Rising insulin levels over time can lead to inflammation, irritability, fatigue

We check:
Fasting insulin, HOMA-IR, glucose curves, A1C, and nutrient response


3. Cortisol and circadian rhythm

  • High evening cortisol = wired but tired

  • Flat morning cortisol = dread, overwhelm, no get-up-and-go

  • Dysregulated rhythm often gets labeled as "generalized anxiety" — when it's hormonal

We may check:
AM cortisol, salivary panels, or symptoms over 24 hours


4. Perimenopause, PCOS, and low testosterone

  • Estrogen and progesterone imbalances can cause heart racing, insomnia, and mood swings

  • Low testosterone (in men or women) can present as anxiety, low motivation, or sensory overload

  • PCOS patients may experience cycles of anxious energy → crash


5. Nutrient deficiencies

  • Low B12, magnesium, iron, and omega-3s can affect mood and focus

  • MTHFR-related methylation issues can cause anxiety in response to stress or histamine


🩺 Our approach:

  • Validate your experience — anxiety is real, whether or not it’s the root

  • Zoom out before labeling — we don’t treat labs in isolation, and we don’t treat emotions as pathology

  • Layer in lifestyle, nervous system regulation, nutrition, and clinical testing

  • Only introduce meds or supplements when the system as a whole makes sense

We believe anxiety is not a diagnosis — it’s a signal. Our job is to decode it.


💡 Bottom line:

Anxiety isn’t always in your head.
Sometimes it’s in your thyroid, your gut, your glucose, or your trauma history.
We look at all of it — not to overcomplicate your care, but to get it right.
