I have low vitamin d and calcium deficiency low, can this cause dizzy spells and the urge to have a sweet drink?

Should not: Sugar cravings can be a possible sign of candida overgrowth, or adrenal fatigue. Dizziness can be due to hypoglycemia which can also be a sign of adrenal fatigue. See your doctor and get checked out. Make sure you are not diabetic.

No: Sx of low vit d includes soft bones ( osteomalecia), bone and muscle aches/pains. Sx of low calcium include muscle irritability with twitching and cramping, numbness and tingling in the hands, feet and around the mouth. Dizziness and craving sweets may be a sign on low blood sugar a separate issue.
