Decode What Your Body
Is Trying To Tell You
Fatigue, weight gain, poor recovery, low libido, cravings, bloating, brain fog and hormonal symptoms often have a deeper metabolic or hormonal pattern. The FITDOC Symptom Decoder helps identify where to start.
The Problem
You're not lazy. Your body may be giving you signals.
These symptoms are commonly dismissed — but they're often the early signs of hormonal imbalance, metabolic dysfunction, or nutrient deficiency. They deserve a proper clinical look.
Constant fatigue
Weight gain or stubborn fat
Cravings & blood sugar dips
Low libido
Poor gym recovery
Brain fog
Mood swings
Bloating
Sleep disruption
Irregular cycles or menopausal symptoms
If you experience three or more of these regularly, your body is likely signalling a pattern worth investigating.
What the Decoder Evaluates
Eight clinical pillars of metabolic health
The Symptom Decoder maps your responses against clinically recognised patterns across these key health domains.
Hormones
Testosterone, oestrogen, progesterone, DHEA, LH, FSH — the foundations of energy, mood and body composition.
Thyroid
TSH, T3, T4, antibodies — the master regulator of metabolism, weight, temperature and energy.
Insulin & Glucose Control
Fasting glucose, insulin, HbA1c — identifying pre-diabetes, insulin resistance and metabolic dysfunction.
Cortisol & Stress Load
Adrenal function, HPA axis, chronic stress response — the hidden driver of fat storage and fatigue.
Gut Health
Inflammation markers, microbiome indicators, digestive function — linked to mood, immunity and nutrient absorption.
Nutrient Deficiencies
Vitamin D, B12, iron, ferritin, zinc, magnesium — deficiencies that silently impair energy and recovery.
Sleep & Recovery
Sleep architecture, recovery markers, melatonin and cortisol rhythms — the foundation of restoration.
Training & Lifestyle Load
Overtraining indicators, inflammatory load, readiness — matching your body's capacity to your demands.
