Sudden, unexplained weight loss accompanied by thirst and fatigue may signal the onset of diabetes. Health authorities emphasise the importance of early recognition to prevent serious complications.
Sudden, unintentional weight loss can be a warning sign of diabetes, particularly when it comes alongside persistent thirst, frequent urination and unusual fatigue, according to the US Centres for Disease Control and Prevention and the Mayo Clinic. Health experts say these symptoms can appear before a person realises their blood sugar is elevated, making early recognition important.
The CDC says diabetes can cause the body to lose weight because it cannot use glucose properly for energy. In that situation, it begins breaking down fat and muscle instead. The organisation and the Mayo Clinic both note that unexplained weight loss is especially significant when it happens without changes to diet or exercise.
Doctors generally regard a loss of about 5% of body weight, or roughly 10lb, over six to 12 months as worth investigating, especially if other signs of high blood sugar are present. Those can include increased hunger, blurred vision, dry skin and wounds that heal slowly, according to the CDC, Mayo Clinic, Cleveland Clinic and WebMD. The effect can be more noticeable in type 1 diabetes, where the immune system destroys the insulin-producing cells of the pancreas.
Because type 2 diabetes can develop gradually, some people may dismiss the early symptoms or attribute them to stress or ageing. Health sources say anyone noticing unexplained weight loss together with thirst, hunger or repeated urination should seek medical advice and ask about blood sugar testing.
