Losing more than five per cent of your body weight over six to twelve months without trying is worth investigating, whatever your starting weight.

Why it matters

Unintended weight loss is a general signal rather than a specific one. Digestive conditions, thyroid disease, diabetes, infection and cancer can all present this way, which is why it is investigated rather than watched.

Important

Weight loss with difficulty swallowing, bleeding or persistent abdominal pain should be assessed without delay.

When should I see a doctor about weight loss?
Book a consultation if symptoms persist, get worse, wake you at night, or come with bleeding, fever or unexplained weight loss. Anything that does not settle within a few weeks is worth having looked at.
Will I need surgery?
Often not. Many conditions settle with medication, physiotherapy or a change in daily habits. Surgery is discussed when simpler measures have been tried, or when the problem is structural.

Still unsure what is causing your symptoms?

A short consultation with a Lux bariatric & GI surgery specialist can tell you what you are dealing with — and what, if anything, needs treating.
