Dizzy after breast feeding

I recently had a baby who is quite big for his age. He eats a lot and I sometimes feel dizzy after breast feeding. Kindly let me know what the cause of the problem could be.

Some breastfeeding mothers feel dizzy after breastfeeding due to causes like low blood sugar, dehydration, and occasional hormonal flunctuations. Breastfeeding uses a lot of the body’s energy, and the significant hormonal and physiological changes after birth can also lead to temporary dizziness. 

It is important for you as a nursing mother to make sure that you increase your fluid intake as well as eating a balanced diet.
