What may cause hypoglycaemia to a healthy person?

  • A

    Excessive intake of vitamin C.

  • B

    Not eating regularly.

  • C

    Flying at high altitudes without oxygen.

  • D

    Decompression sickness.

HYPOGLYCAEMIA
Skipping meals or fasting can lead to low blood sugar (hypoglycaemia), typically when levels drop below about 50 mg per 100 ml of blood. Common symptoms include:

  • Headache
  • Abdominal discomfort
  • Low energy levels
  • Irritability or nervousness
  • Trembling
  • Drowsiness
  • Poor concentration
  • In severe cases, fainting

In the short term, hypoglycaemia can be improved by eating a small snack.

Let's analyze the given options:

Excessive intake of vitamin C. → INCORRECT. Vitamin C does not lower blood sugar to dangerous levels in healthy people. It is not a cause of hypoglycaemia.

Not eating regularly. → CORRECT. Skipping meals or fasting reduces glucose intake, causing blood sugar levels to drop, which can lead to hypoglycaemia even in healthy individuals.

Flying at high altitudes without oxygen. → INCORRECT. This leads to hypoxia (low oxygen levels), not low blood sugar.

Decompression sickness. → INCORRECT. This condition is related to nitrogen bubble formation due to pressure changes, not blood glucose levels.
