Yes — hypothyroidism causes weight gain ranging from 3-10 kg. But the truth is most of the gain is fluid, not fat.
Why Weight Increases:
- Slow metabolism: Body burns fewer calories — weight increases even with same food intake.
- Fluid retention: Body retains water and salt — most initial gain is fluid.
- Myxedema: Substance accumulation in skin and tissues causes puffiness.
- Reduced activity: Fatigue reduces movement — a vicious cycle.
Why Weight Loss Is Slow Even With Treatment:
- Dose adjustment takes 6-8 weeks — body needs time.
- Fluid loss first: First 2-3 kg will drop quickly after starting treatment — that's fluid.
- Accumulated fat needs diet and exercise in addition to treatment.
- Some patients develop poor eating habits during hypothyroidism — need correction.
Advice:
Don't blame the thyroid for all excess weight — after dose stabilization, if weight doesn't decrease, the cause is likely lifestyle, not thyroid.
