Why Do I Feel Faint or Lightheaded?

Dear Blossom,

Recently I’ve had to move up a doctor’s appointment because I’ve felt mildly faint at work–even when I’ve had adequate rest and exercise. Would you share some pointers for noticing when blood pressure or blood sugars might be changing?–Helena

Thank you for your question, Helena. To answer, allow me to share some of the top reasons why you may feel faint or lightheaded when standing up or anytime throughout the day after having bariatric surgery.

  1. Low blood sugar. You may not feel hungry thanks to your new small sleeve, but your body will tell you it needs glucose by making you feel dizzy, lightheaded, breaking out in a sweat or feeling faint. The best ways to get that glucose into your cells is with a few bites of no sugar added applesauce, or a teaspoon of real peanut butter with some real honey mixed in it. While we stress the importance of protein, carbohydrates in your daily diet in the forms of vegetables, lentils and beans also play an important role.
  1. Dehydration. If you have symptoms mentioned above, you may be dehydrated. Drink an electrolyte-enhanced bottled water, coconut water, or even pedialyte to replace electrolytes quickly. Once dehydrated, reaching for an electrolyte-enhanced beverage will help you rehydrate more quickly than water.
  1. Adrenal fatigue. Your doctor might not know how to test for adrenal fatigue, but one of the most prevalent markers for adrenal dysfunction is dizziness upon standing or very low blood pressure readings. B vitamins, clean protein and healthy fats support your adrenals which are responsible for helping your body overcome stress.

Keeping your blood sugar levels regulated, staying hydrated and taking the proper vitamin supplements will help overcome dizziness spells.
