Morning sickness, which rarely happens only in the morning, is no fun. Oftentimes women just feel nauseous and blah, but some women throw up several times a day and cannot keep anything down throughout the whole pregnancy. There are several theories as to what causes nausea in pregnancy and here I explore three of them. First the body is detoxing; Second, low blood sugar; and third, low in magnesium. Unfortunately, not one thing works for everyone, so I have included here a list that work from most successful to what works for only a few. I encourage women to be proactive keep trying them until they find what works for them.
