𩺠Specific Conditions
This guidance is general information only and does not replace medical advice.
š¬ Diabetes
Type 1 Diabetes
A VLCD or Total Diet Replacement plan is not suitable unless managed directly by your specialist diabetes team.
Type 2 Diabetes
You may be able to follow the plan under medical supervision. Rapid weight loss can significantly reduce blood glucose levels and medication requirements. Your GP or diabetes nurse may need to adjust treatment to reduce the risk of hypoglycaemia.
Do not begin without professional supervision.
𦓠Gout
Rapid weight loss may temporarily increase uric acid levels, which can trigger gout flare-ups.
If you have a history of gout, consult your GP before starting.
š§ Epilepsy
Changes in weight and nutritional intake can affect seizure control or medication levels.
Speak to your GP or specialist before starting.
š¦ Thyroid Conditions
If you take thyroid medication, dosage may need monitoring during significant weight loss.
Consult your GP before beginning.
ā¤ļø High Blood Pressure
Weight loss can improve blood pressure, but medication doses may require adjustment as levels change.
Medical advice is recommended before starting.
