In general, a blood glucose level in the range of 1.x mmol/L represents a severely low state, which may pose risks of coma, seizures, cardiovascular and cerebrovascular events, cognitive impairment, and accidental injuries.

1. Coma: Severely low blood glucose can lead to insufficient energy supply to the brain and may rapidly cause coma.

2. Seizures: Hypoglycemia may cause abnormal electrical activity in the nervous system, leading to seizures.

3. Cardiovascular and cerebrovascular events: Hypoglycemia triggers a stress response in the body, causing increased heart rate and elevated blood pressure, which may induce myocardial infarction or stroke.

4. Cognitive impairment: Prolonged or recurrent hypoglycemia may cause damage to brain neurons, impair cognitive function, and even increase the risk of dementia.

5. Accidental injuries: Hypoglycemia may cause dizziness, fatigue, and confusion, increasing the risk of falls, traffic accidents, and other accidental injuries.

It is important to maintain a balanced diet, avoid strenuous exercise that may cause sudden drops in blood glucose, and adjust the dosage of glucose-lowering medications under medical guidance to prevent hypoglycemic episodes.
