Hypoglycaemia (usually below 70 mg/dL) happens in diabetics on insulin or certain tablets — from a delayed meal, extra exertion, or too large a dose. The brain runs on sugar, so consciousness deteriorates fast if you don't act.

In short — what to do

  1. Give 15 grams of fast sugar: half a cup of juice, 3 dates, 3 teaspoons of sugar in water, or glucose tablets.
  2. Wait 15 minutes and re-check the sugar if a meter is available.
  3. Still low or still symptomatic? Repeat another 15 grams.
  4. After improvement: a real snack (bread, dates with milk) to hold the sugar up.

The biggest low-sugar mistake: chocolate

21 seconds

Chocolate and biscuits: the fat slows sugar absorption. The right move is 15 grams of fast sugar: half a cup of juice, 3 dates, or 3 teaspoons of sugar in water. Wait 15 minutes, and repeat if still low or still symptomatic.

A low comes without warning: keep dates ready

10 seconds

Keep dates or glucose tablets in the car, the office and your pocket, and teach the household the 15/15 rule — a low comes suddenly and doesn't ask permission.

The full details

The signs

  • Cold sweat, tremor, palpitations, intense hunger.
  • Confusion, sudden irritability, strange speech — they may seem "drunk".
  • And in severe cases: drowsiness, seizure, unconsciousness.

Awake and able to swallow? The 15/15 rule

  1. Give 15 grams of fast sugar: half a cup of juice, 3 dates, 3 teaspoons of sugar in water, or glucose tablets.
  2. Wait 15 minutes and re-check the sugar if a meter is available.
  3. Still low or still symptomatic? Repeat another 15 grams.
  4. After improvement: a real snack (bread, dates with milk) to hold the sugar up.

Unconscious or can't swallow?

  1. Put nothing in their mouth — no juice, no honey; they will choke.
  2. Place them in the recovery position and call 998 immediately.
  3. If a glucagon kit is available and someone knows how: give it now.

Common mistakes

  • Giving chocolate or biscuits — the fat slows sugar absorption.
  • Injecting insulin "to fix the situation" — the low gets lower.
  • Letting them drive or sleep before confirming the sugar has risen.

For diabetics and their families
