‘My blood sugar level is at 230 mg/dL. Is it dangerous, or can it be controlled?’

A blood sugar level of 230 mg/dL can cause alarm, but it's important to understand what this number really means. The same reading can indicate different things depending on when it was measured. Fasting glucose reflects the glucose released by the liver overnight, while post-meal glucose includes the glucose from food eaten. Dr Rajiv Kovil, a Diabetes & Obesity Specialist, explains that a single high reading doesn't tell the whole story.

To determine the full picture of blood sugar control, doctors should also consider HbA1c, which reflects average glucose exposure over the previous 2-3 months.

Diabetes is often discovered incidentally during routine blood tests, as high glucose levels may remain silent for years. If your blood sugar is 230 mg/dL, regularly checking it at home isn't enough. Seeking medical advice and getting a proper evaluation is crucial. Dr Kovil advises against treating just the sugar number, as diabetes management involves broader metabolic health.

This evaluation may include kidney function, blood pressure, cholesterol, and a retinal examination, along with screening for metabolic dysfunction-associated steatotic liver disease (MASLD) or fatty liver.

While a blood sugar level of 230 mg/dL can usually be controlled through structured nutrition, physical activity, weight management, and medication when needed, the exact approach depends on individual health and diabetes status. It's also important to note that a reading of 230 mg/dL doesn't automatically require emergency treatment.

However, if high blood sugar is accompanied by symptoms like vomiting, dehydration, abdominal pain, rapid breathing, severe weakness, drowsiness, or confusion, urgent medical attention is necessary. Dr Kovil emphasizes that while a high blood sugar reading isn't a reason to panic, it should prompt action to treat the person and their overall metabolic risk.
