As mentioned earlier, dehydration can cause problems, owing to inadequate fluid intake during fasting. At the same time, electrolyte imbalance (loss of essential minerals like potassium and magnesium) may also be a cause. In some people, fluctuations in insulin, cortisol, and adrenaline can cause vision issues. Besides that, nutrient deficiencies like inadequate intake of omega-3 fatty acids, vitamin A, and antioxidants are also culprits.
