Why symptoms are often missed in India
Type 2 diabetes develops slowly, and symptoms like tiredness or increased thirst are easy to blame on heat, stress, or ageing. Studies suggest a large fraction of diabetes in India is undiagnosed until complications appear. Knowing the pattern helps you seek testing early.
Type 1 diabetes in children and adolescents usually comes on faster, with obvious thirst, weight loss, and vomiting — this is a medical emergency if ketoacidosis develops.
Classic symptoms of high blood sugar
- Excessive thirst (polydipsia) and dry mouth
- Frequent urination, including at night
- Unexplained weight loss despite eating well
- Increased hunger
- Fatigue and poor concentration
- Blurred vision
- Slow-healing cuts, boils, or fungal infections
- Tingling or numbness in feet
- Dark velvety patches on neck or armpits (acanthosis nigricans)
Symptoms more common in Indian clinical practice
Recurrent skin and urinary infections, repeated boils, and gum infections are frequently the first clue. Many patients report 'weakness' and leg cramps rather than classic textbook thirst. Central weight gain with normal or modest BMI still warrants glucose testing in South Asian families.
Women with PCOS, gestational diabetes history, or irregular periods should screen even without obvious symptoms.
When to see a doctor urgently
Seek emergency care for vomiting with abdominal pain and very high sugars (possible DKA), fruity breath, confusion, or glucose below 54 mg/dL with altered consciousness. For gradual symptoms, book fasting glucose, HbA1c, and a physical exam including foot sensation and blood pressure.
Do not wait for symptoms to become severe. If you are over 30 with a family history, ask for annual screening at your local clinic or diagnostic lab.
