How adrenal insufficiency triggers life-threatening hypoglycaemia risks

Adrenal insufficiency (AI) can lead to dangerously low blood sugar levels, a condition known as hypoglycaemia. This happens because the body lacks enough cortisol, a hormone that helps regulate blood sugar. Without it, people with AI struggle to raise their glucose when levels drop too far. Hypoglycaemia is particularly common in children with AI and those with secondary AI. Their higher energy demands and lower glucose reserves make them more vulnerable. Early signs of the condition include fatigue, shaking, sweating, and confusion. In severe cases, sufferers may lose consciousness or even have seizures.

For some, hypoglycaemia can be the first warning sign of AI. Doctors have recorded cases where it revealed undiagnosed secondary AI. Mild episodes can often be treated by eating or drinking something sugary. But severe drops in blood sugar may signal an adrenal crisis—a life-threatening emergency. An adrenal crisis requires immediate treatment with an emergency hydrocortisone injection to restore cortisol levels. Without fast action, the situation can become critical. Preventing hypoglycaemia in AI involves careful management: sticking to treatment plans, adjusting hydrocortisone doses during illness or stress, and making lifestyle changes. Reducing stress, following exercise advice, and eating enough carbohydrates all help keep blood sugar stable. The long-term outlook for those with AI and hypoglycaemia varies. Milder cases respond well to treatment and monitoring. But severe episodes, especially adrenal crises, carry higher risks and require urgent medical care.

Managing AI and hypoglycaemia relies on early recognition of symptoms and prompt treatment. Regular monitoring and dose adjustments help prevent dangerous drops in blood sugar. For those at risk, understanding the link between cortisol deficiency and glucose control remains crucial for staying healthy.
