Why can skipping meals be risky for a diabetic patient taking insulin?

Correct answer: Blood glucose may become too low

The direct answer is A: blood glucose may become too low. Insulin helps move glucose from the blood into body cells, thereby lowering the glucose level in the bloodstream. If a person takes insulin and then skips or greatly delays a meal, less glucose may enter the body from food while the insulin effect may continue. This mismatch can cause hypoglycaemia, or abnormally low blood glucose. Possible warning signs include sweating, shaking, hunger, weakness, dizziness, confusion, or loss of consciousness. A is correct because it describes the real risk. B is wrong because insulin and missed meals do not make bones grow immediately. C is wrong because food colour has no connection with this blood-glucose mechanism. D is scientifically impossible and unrelated. The exact meal and medicine plan must be decided with a healthcare professional; a patient should not change insulin doses independently. Memory cue: insulin lowers blood glucose, so insulin plus too little food can mean glucose goes too low.
