What unexplained weight loss can point to, how urgent it is, and who assesses it in the UAE.

Also known as losing weight without trying

Get checked promptly

This needs a prompt medical assessment

Unexplained weight loss has many causes and most of them are not cancer — but it is on the list of features that doctors investigate quickly rather than watch. Getting it checked early is what makes the difference.

Go now if any of these apply

A new lump, or a lump that is growing, hard, or fixed in place
A symptom that has persisted for more than three weeks without improving
Unexplained weight loss, drenching night sweats, or persistent fatigue
Bleeding that is unexplained — in stool, urine, when coughing, or after the menopause
A mole or skin lesion that is changing in size, shape, colour, or is bleeding

Book a doctor's appointment within the next few days and say how long the symptom has lasted. Ask specifically whether an urgent referral or a scan is warranted.
