Question – I am non-diabetic but have had low blood sugar after bariatric surgery. What should I do?
There are many reasons why a person feels light headed and dizzy after bariatric surgery. One such reason is hypoglycemia. Hypoglycemia is a possibility after both gastric sleeve and gastric bypass surgery.
- Hypoglycemia or low blood sugar is a complication of gastric bypass or any other bariatric surgery, including mini gastric bypass surgery or gastric balloon.
- According to Cleveland Clinic Journal of Medicine, post-gastric bypass hypoglycemia (PGBH) should initially be treated with a diet rich in fiber and protein but low in carbohydrates.
- It further states that if the problem persists, medication such as “acarbose or a calcium channel blocker and octreotide or diazoxide or both” can be taken.
Symptoms of Non-Diabetic Hypoglycemia Post Weight Loss Surgery
It is not necessary to experience any of these symptoms to have hypoglycemia. Such a condition has been termed as Hypoglycemia Unawareness.1 Some common symptoms are-
- Blurred Vision
- Extreme Hunger
- Excessive Sweating
- Problem in Concentrating
Severe hypoglycemia patients exhibit symptoms like rapid heartbeat, seizures, nausea and anxiety.2
Causes of Hypoglycemia After Bariatric Surgery
Some factors3 that put a person at a greater risk for hypoglycemia are –
- A very high dose of medication (either insulin or hypo causing tablets)
- Irregular meals
- Too much exercise
- Deficiencies in counter-regulatory hormones (cortisol, glucagon and epinephrine)4
Alleviating Hypoglycemia Following Bariatric Surgery
Post bariatric hypoglycemia can be life threatening as it can be accompanied with dizziness and seizures, which gives rise to motor vehicle accidents as well.5 This is why it is necessary to eat right and drink the right amount of fluids. One needs to have a protein rich balanced diet. (Some post-op stage 3 diet ideas).
Research indicates that post-gastric bypass hypoglycemia (PGBH) specifically occurs postprandially, after 6 months of the surgery.6
- Mild hypoglycemia can be treated by taking glucose orally or by consuming foods that contain carbohydrates. For instance, juice, candy or a small meal.7
- Try drinking about one-third of a cup of juice.
- Have a protein + glucose stabilizer bar.
- If you are more than 1 week out from bariatric surgery, you can have some puréed fruit, yogurt with a little sweetener, or mashed potatoes.
- For those of you that are longer out, 1/2 a piece of fruit and 1 oz of cheese or 1 tbs of nut butter is a great snack to have.
- Eat something with at least 15 gm of carbohydrates every 3 hours to help prevent hypoglycemia.
- Good choices are fruit, Greek yogurt, 3-6 whole grain crackers, oatmeal, roasted potatoes, brown rice, dried fruit, or whole grain bread (if you can tolerate it).
