In general, our body produces insulin to help metabolize carbohydrates or sugar and reduce blood glucose levels. Whenever carbohydrates or sugar is consumed in large amounts, our blood glucose fluctuates which can lead to muscle tightening and anxiety. The corresponding increase in insulin can also lead to heighten pain sensitivity hence increasing pain.
Additionally, sugar is known to cause yeast or Candida to proliferate in the stomach or vagina. This results in yeast infections causing pain or discomfort in the gastrointestinal tract and vagina.
The increased intake of carbohyrates or sugar can also cause nutritional deficiencies as many ten to take in less vegetables and proteins.
