LOW BLOOD SUGAR — COMMON IN DIABETES TREATMENT
Hypoglycemia
A condition of abnormally low blood sugar causing sweating, shakiness, weakness, confusion and faintness. Common in diabetes treatment, requiring prompt sugar intake and review of medication.
ABOUT THIS CONDITION
What is Hypoglycemia
Hypoglycaemia is a condition in which blood sugar levels fall below the normal range, depriving the body and brain of their main source of energy. It is most commonly seen in patients with diabetes, particularly those on insulin or certain anti-diabetic medications, but can also occur in other situations such as missed meals, excessive alcohol intake or specific hormonal disorders. Typical symptoms include sweating, shakiness, palpitations, hunger, weakness, dizziness, irritability and difficulty concentrating. Severe hypoglycaemia can cause confusion, seizures, loss of consciousness and, if untreated, can be life-threatening. Prompt treatment with fast-acting sugar, followed by a longer-acting snack, usually restores normal blood sugar quickly. Identifying the cause and adjusting diabetes treatment is essential to prevent recurrence. Dr. Patnam Pravallika Reddy provides assessment, treatment and personalised diabetes adjustment at Lux Hospitals, Hyderabad.

HOW WE TREAT IT
Treatment Approach
Prompt Sugar Correction with Medication Adjustment
The most effective approach is immediate correction with fast-acting sugar in mild and moderate episodes, glucagon or IV glucose in severe cases, followed by careful review and adjustment of diabetes medication to prevent recurrence.
- 1

Dr. Pravallika reviews the pattern, timing and severity of hypoglycaemia, examines you and orders blood tests to assess overall control.
- 2
Treatment Planning
A personalised plan is created to manage acute episodes and adjust medications and lifestyle to prevent further low-sugar events.
- 3
Medical Management
Adjustment of insulin or anti-diabetic medication, structured meal and activity planning, and detailed education on recognising and managing low blood sugar.
- 4

AVAILABLE TREATMENTS
Treatment Options
Oral Glucose if Conscious
Fast-acting sugar such as glucose tablets, fruit juice or sweets is given to bring blood sugar back to normal in conscious patients.
IV Dextrose or Glucagon if Unconscious
In severe hypoglycaemia with loss of consciousness, intravenous dextrose or a glucagon injection is given urgently.
Identifying Cause
Each episode is reviewed to find the cause — over-medication, missed meals, unplanned activity, alcohol intake or other factors.
Adjusting Diabetic Medications
Insulin or oral anti-diabetic medication doses are adjusted to reduce the risk of further low-sugar episodes.
Patient Education
Detailed education on warning signs, self-treatment, sick-day rules, exercise planning and avoiding repeated episodes.
