Diabetic Foot Care: The Ten Minutes a Day That Prevent Amputation
Most diabetic amputations begin with a wound the patient never felt. A daily foot inspection is the single most cost-effective preventive habit in diabetes care.

A diagnosis of type 2 diabetes is not a sentence — it is a starting point. What you do in the first twelve months determines much of what the next thirty years look like.
Understand what the numbers mean
- Fasting blood sugar: normal below 100 mg/dL, prediabetes 100–125, diabetes 126 or above
- Post-meal (2 hours): normal below 140 mg/dL, diabetes 200 or above
- HbA1c: normal below 5.7%, prediabetes 5.7–6.4%, diabetes 6.5% or above
- Target for most adults with diabetes: HbA1c below 7%, individualised by age and other conditions
Worth knowing
HbA1c reflects average sugar over roughly three months. A single good fasting reading before a clinic visit does not change it — which is precisely why it is the test we rely on.
The dietary changes that actually work
The most useful change for most South Indian households is not eliminating rice but restructuring the plate. Fill half the plate with vegetables, a quarter with protein — dal, egg, fish, chicken, paneer or soya — and only a quarter with rice or roti. The same quantity of rice eaten after vegetables and protein produces a substantially lower sugar spike than rice eaten first.
Replace refined rice with hand-pounded or brown rice, or mix millets such as ragi, jowar and bajra into the rotation — these are traditional Rayalaseema grains that have simply fallen out of daily use. Avoid fruit juice entirely, since removing the fibre turns fruit into sugar water. Whole fruit in moderation is fine.
Do not skip meals to control sugar. Long gaps cause the liver to release glucose and lead to overeating later. Three meals with consistent timing beat erratic eating with 'compensation'.
Movement matters more than the gym
A brisk thirty-minute walk on most days improves insulin sensitivity for up to 48 hours. Walking for ten to fifteen minutes after each main meal blunts the post-meal sugar spike more effectively than one long walk at another time of day — a small change that costs nothing and works.
Resistance work matters too. Muscle is where glucose is stored, and more muscle means better sugar handling. Two sessions a week of simple bodyweight exercise — squats, wall push-ups, stair climbing — makes a measurable difference over months.
The screening schedule nobody explains
- HbA1c every three months until stable, then every six months
- Blood pressure at every visit — target below 130/80
- Lipid profile annually
- Urine microalbumin annually, to catch kidney involvement early
- Serum creatinine and eGFR annually
- Dilated eye examination annually, even with perfect vision
- Foot examination at every visit, with a full sensory check annually
- Dental review annually — gum disease and diabetes worsen each other
Medication myths worth discarding
Starting insulin does not mean the disease has reached its final stage, and it is not a punishment for poor control. Insulin is sometimes the safest and most effective option, particularly during infection, surgery or pregnancy, and is often temporary.
Metformin is not 'hard on the kidneys' — it is one of the safest and most studied drugs available and is continued in mild to moderate kidney impairment. Stopping medicines because sugar has normalised is the most common cause of relapse we see; the sugar is normal because the medicine is working.
Signs that need same-day medical attention
- Blood sugar above 400 mg/dL with vomiting, abdominal pain or drowsiness
- Sugar below 70 mg/dL with sweating, trembling or confusion
- A foot wound, blister or blackened area, however small and however painless
- Fever with reduced urine output
- Sudden blurring of vision
Key takeaways
- Restructure the plate rather than eliminating rice — vegetables and protein first, carbohydrate last.
- Walk ten to fifteen minutes after each meal to blunt post-meal sugar spikes.
- Annual eye, kidney and foot screening are non-negotiable, even without symptoms.
- Never stop medication because sugar has normalised — that is evidence it is working.
