When unexplained weight loss needs a doctor — soon

·Loss of more than 5 kg without dieting
·Loss of appetite or early satiety
·Change in bowel habits or blood in stool
·Night sweats or persistent low-grade fever
·New lumps, persistent cough, or jaundice

This is general guidance, not a diagnosis. If you have any of the above, book a same-day consult or seek urgent care.

Common causes a physician will look for

·Uncontrolled diabetes — high sugars literally spill calories into urine
·Hyperthyroidism — weight loss with palpitations and heat intolerance
·Chronic infection (TB is still common in India)
·Malabsorption — coeliac disease, chronic pancreatitis, IBD
·Less common but important to rule out: malignancy, depression

What to expect at the consult

Detailed history, examination, and a structured work-up: HbA1c, TSH, CBC, CRP, liver/kidney profile, chest X-ray, stool screen, and imaging only when indicated. Speed matters; investigations are usually completed within a week.
