Endocrine causes of stubborn weight gain
We routinely identify hormonal contributors that have been missed for years. Treating the underlying disorder doesn't just help with weight — it usually improves energy, sleep, mood, and metabolic health overall.
- Hypothyroidism — An underactive thyroid slows metabolism and adds 5–20 lbs of stubborn weight.
- Insulin resistance & pre-diabetes — High insulin levels drive fat storage, especially around the abdomen.
- PCOS — Hormone imbalance combined with insulin resistance — common in women of reproductive age.
- Cushing's syndrome — Excess cortisol drives weight gain, particularly truncal and facial.
- Hypogonadism (low testosterone) — Loss of lean muscle and increased fat mass in men.
