How to Maintain Normal Blood Sugar After weight loss surgery

Weight loss surgery is one of the best ways to lose weight effectively. There are three different types of weight loss surgery. Gastric bypass surgery, Sleeve gastrectomy and Gastric banding are the common three different types.

Gastric Bypass Surgery

Gastric bypass is a type of weight loss surgery that doctors perform by changing the stomach and the small intestine in a way to lose a significant amount of weight. Patients lose an average of 3 to 5 kgs every month for a year following the surgery. The result of weight loss surgery is accompanied by better overall health and improved confidence.

Complication – Low Blood Sugar

But like every other surgery gastric bypass surgery has some complications too. One of these complications in few cases are the occurrence of low blood sugar. This is also known as postprandial or reactive hypoglycemia. It mostly can’t be noticed for almost a year, post-surgery. In such cases, patients produce too much insulin after the meal and become more sensitive to the blood sugar-lowering effects of their insulin.


This complication can be recognized easily by its symptoms which mostly occurs after one to three hours of having a meal. Symptoms include:

  • Confusion
  • Anxiety
  • Cold sweats
  • Dizziness
  • Hunger
  • Shakiness
  • Unconsciousness but very rare

Tips To Manage It

Most gastric bypass patients usually don’t experience reactive hypoglycemia, but those who do should know how to manage it. Throughout the day you need to maintain a constant blood sugar level. Tips include:

  • Eat three to four balanced meals every day, with equal times apart.
  • Take carbohydrate as minimum as possible, especially if you have a high glycemic index.
  • Since sweets ultimately increase blood sugar by stimulating insulin secretion, limit their intake.
  • Follow a doctor’s and dietician’s advice on what to include in your regular diet to maintain normal blood sugar.
  • Pay attention to symptoms and act before they become severe, especially while driving or engaging in any other potentially dangerous activities.

These steps will help you keep your blood sugar level to normal. Try to prevent it from happening even if only one symptom becomes apparent. Weight loss surgery is seemingly an easy procedure with minimum complications. But our advice is if you are prone to reactive hypoglycemia monitor yourselves closely for the next few hours of a meal and be sure to eat again shortly. If the complication becomes persisting, contact your doctor.
