What happens when someone with diabetes has a blood sugar of 29?

A blood sugar level of 29 (mmol/L) is extremely high and considered a medical emergency.

When a person with diabetes has a blood sugar this high, their body becomes unable to effectively use the insulin it produces or takes, which leads to a severe buildup of glucose in the bloodstream. This condition is known as diabetic ketoacidosis (DKA).

DKA occurs when the body starts breaking down fat and muscle for energy instead of glucose, producing ketones as a byproduct. Ketones can accumulate in the blood and urine and cause several severe complications.

Symptoms of DKA include:

- Extremely high blood sugar levels (above 24 mmol/L or 432 mg/dL)

- Frequent urination

- Excessive thirst

- Dry mouth

- Weakness and fatigue

- Nausea and vomiting

- Abdominal pain

- Shortness of breath

- Fruity-scented breath (due to the presence of ketones)

- Confusion or altered mental status

If left untreated, DKA can lead to severe dehydration, electrolyte imbalances, coma, and even death. It's crucial for individuals with diabetes to monitor their blood sugar levels regularly and seek immediate medical attention if their levels reach dangerously high levels.
