Thiazolidinediones
Medications that improve how your body responds to insulin.
💡 These medications help your body use insulin more effectively.
How They Work
Thiazolidinediones (e.g. pioglitazone) increase the body’s sensitivity to insulin.
- Improve insulin action in muscle and fat
- Reduce insulin resistance
💡 They do not increase insulin production.
Benefits
📉 Improves insulin sensitivity
Helps the body use glucose more effectively.
🛡️ Low risk of hypoglycaemia
Unlikely to cause low blood sugar on its own.
How Quickly Do They Work?
These medications work slowly and may take several weeks to show full effect.
💡 They are not used for rapid blood sugar control.
Common Side Effects
- Weight gain
- Fluid retention (swelling)
Important Considerations
- May cause swelling in legs or ankles
- Not suitable for people with heart failure
- Regular monitoring may be required
⚠️ Fluid retention can worsen heart conditions and should be monitored carefully.
Practical Tips
- Report swelling or rapid weight gain to your doctor
- Take medication regularly as prescribed
- Continue lifestyle changes alongside treatment
Key Takeaway
Thiazolidinediones improve insulin sensitivity but are used carefully due to side effects.
💡 They may be useful in selected patients as part of a broader treatment plan.
